Behavioural gamma and fractal attractions - I blame the Russians.


I am fast wondering if someone has perfected the ultimate 'hunt and destroy’ algo trading weapon. The development of programs that can sniff out other’s stop levels and micturate all over them before running off maniacally laughing with their positions has been around for years, but the precision with which market moves have sliced and diced the flesh from many a portfolio this month has me wondering if the Russians have developed the killer algo of all killers.

I don’t really wonder if it’s the Russians, I more expect someone else to wonder if it's the Russians because if anything that involves a computer and cannot be easily explained, or rather can be easily explained by ‘yeah ok, I was dumb not to see that coming’ but we don’t want to say that - it's blamed on the Russians. I use it all the time now. My wife popped out of the room during ‘Call the Midwife’ on Sunday night and when she returned the TV was tuned to ‘Dragons Den’. I told her it must have been the Russians as I didn't know where the remote was. She couldn’t find it either to turn the channel back, thus proving my point. We also found that the Russians had turned the thermostat down in our house from 24C to 20C, which I can cope with but the Russians, as my dear wife pointed out, have also cut the power to all the wires and chargers by my bed, emptied the fridge of high-fat foods and hidden my favourite clothes. Damn cunning, these Ruskies.

Markets have turned ‘difficult trading’ into a form of waterboarding. I don’t need to talk you through the details of various asset swings over the last few weeks but if you have a position and your stop loss is in the range zero to infinity,  there is a good chance you have been stopped out. Unless you are an investor, in which case you have waved your hand in a marginally dismissive way whilst tilting your head slightly back to peer down your nose and languidly intone, “No my dear chap, I'm an investor, not a speculator, my investments are to provide me with long-term returns”. Which actually translates to - “ I haven’t got a clue what is going on with the markets as I had a chap come round to the house who sold me this marvellous long-term investment fund, no I don't know what the fees are actually, that I don’t have to look at as he assures me that it will pay me handsomely when I retire. Mr Woodford’s something or other”.

I was taken out today. Out of gold longs, stock shorts, and lunch. Only one was pleasurable.  Mourning the loss of my gold position, I bought a new one as I applied my trading maxim - 'the best time to enter a position is just after you have been stopped out of it’. Sad, but unfortunately true recently.

If you had your screens off for the last 36hrs you could well ask "what Fed minutes?"





This sort of thing hurts when you are suffering from  'fractal attraction’ and  'behavioural gamma'. When you don’t know what is going on you have some choices.

1- Carry on, pretending you do know what is going on - you may get lucky
2- Walk away - Clever, clever, clever.
3- Get angry that you don't know what is going on and make it a mission to know what is going on in an ever more dangerous search down the old mine of broken dreams - Danger danger danger Will Robinson.

Or perhaps Lassie - “What's that Lassie? You saw Polemic trying to dissect every price move down to a 3minute chart looking for patterns in order to look for breakouts that would define the next big move? And you think he needs rescuing? Nah.. he’ll already be dead"

The 'fractal attraction' is the drilling in on tighter and tighter time frame charts in the search for a pattern. Each zoom showing pretty much the same pattern, or lack of one, as the previous. Fractal-like. The 'behavioural gamma' is the chasing of any move that looks as though it is setting the next direction, as you really don't want to miss out, only for you to be caught out on a reversal and have to chase it the other way. Behavioural gamma increases dramatically when there isn’t a fitting narrative. It isn’t options gamma, as it is linked to behaviour not a mathemantically derived hedging demand, but I suppose you could imply a link between behavioural gamma and options gamma stemming from the same source of uncertainty.

One could even go so far as to cogitate if one drives the other or that the total sum of behavioural and options gamma is constant. But my mind is wandering too far.

I guess the point of this ramble is to say. Don't get sucked in. When you don't know what’s going on, walk away, as curiosity may well be terminal feline flu.

Just blame the Russians.

GRReat - the Global Risk Repricing



First a recap -

10 days ago -

My best case is that no narrative can be ignored and all have their strengths.  But instead of them each being a separate diagnosis of different potential diseases they are all symptoms of a single greater one. They are all building into a great big superstorm of grief encapsulated in a super-narrative

Inflation, corrections, a spike in volatility (really an increased cost of insurance), problems in leverage, US bonds, problems in risk parity, China sell-offs, Junk bonds sell off, aren’t all separate but are all part of the same single story - the new super-narrative of ‘The great global risk repricing'

A sudden spasm of awakening to true risks may now be underway.  For years we have been saying that credit is too cheap and that junk bonds are way too expensive and that leverage has been practically free. I hate to hark back to QE, as we know that it has spawned a rash of ridiculous pricing, but this, folks, could be the big one with regards to waking up and smelling the coffee. Free money does not mean any risk.

This reassessment of risk perceptions can also include US Treasuries. If there is a chance that they are no longer the ultimate safe haven then the schism would have dire consequences for the stability of current investment theory. No, I am not saying that US Treasuries aren’t safe as houses, I am saying that all you have to have is people questioning them for problems to kick off as soon as Monday.

And that is why waiting for bonds to go up to know if this is over is all the more important, If they don’t then it is really bad news.

Currencies have worn this move fairly well. Yes, they have moved with the classics like AUDJPY doing the risk off thing, but considering the size of the equity moves they are hanging on in there. Most notably,  the popular position of short USD hasn't really seen much of an unwind but it should be considered as part of the short UST trade. This is not about rate differentials anymore, as we have seen the divergence of rate differentials vs FX widen for the past few months, but about underlying trust in the US to manage its affairs. It's part of the risk adjustment as the US and USD have moved a notch right along the scale between Switzerland and Zimbabwe.

So what do we do? the trader in me wanted to buy on Friday, so I did, but the pragmatist thinks this is far from over.


And then 7 days ago - Shorting the CPI and being stopped out. 

I have to say that today was a hero to zero day for me in equity land. I played the CPI figure perfectly as stocks decided that the inflation story really. really is a concern. Until it isn't. And that ‘until it isn’t’ occurred about 15 seconds after maximum 'it is a really, really big concern'. That was when perfection vanished in a puff of humility and the ‘natural bounce up off the lows'  spent the rest of the day grinding higher up to new highs.

I am not too shy to own up to the stock shorts costing me money. I hate grinds, they are worse than sharp moves mostly because sharp moves engulf your emotions in one hit, whilst grinds tie you naked to a chair and beat your bits with a knotted rope until you are finally put out of your misery by the pistol to the head of a stop loss.

But I JUST KNOW that  US stocks will now tank. But if I don't understand why equities are going up then I must get out. Understand? That where your narrative fits whatever it is you want it to fit, but unless someone takes a 3ft pipe bending machine to the current narrative of ‘it’s inflayshun innit’ to make it fit with today’s moves then I am afraid this narrative is broken

We are getting through narratives faster than plates in a Greek restaurant.

Since then.

I licked my wounds until Monday when I started shorting things again. I couldn’t bear to think about missing the big dump. Why Monday?

Momentum was fading and we had just had a new narrative on the block - Double deficit. The double-deficit was the next big thing. But double deficits are like herpes to many countries. Many have them but are mostly unnoticed. They are a pain and you don't want to give them to anyone but the worst they normally do is sting and everyone points, rings bells and shouts ‘unclean!’.  But when something else comes along they fade away into the background to reside in the ganglion of government statistics. A double deficit? How quaint.

We can have double deficits narrative and we can have inflation narrative and we can combine them in a theory of the US crowding out, but to combine them requires something to happen - risk assets have to reprice lower and the overall discount rate applied to US assets has to go up to compensate for future USD depreciation. Meanwhile, a bit of risk premium creeps into apparently risk free assets.

Now the inflation narrative is only supportive of stocks and commodities and emerging markets if it’s cost-push inflation. In this scenario, short end rates rally a touch as Fed lags as it is cost driven. But if the inflation is demand-pull inflation we have a different position as the Fed will tighten faster, real yields will go up, bear flattening the curve and stocks will fall as the market starts to worry about a potential recession from a potential Fed over tightening.

So we have both inflation and double deficit - stocks down
Cost-push inflation - stocks up
Demand-pull inflation - stocks down

Two out of three are down for stocks.

Today the Fed showed their hand and stocks fell.

And now?

I am hoping that the narrative will now find some clarity, but I am still very aware that this narrative is US-centric, yet major panicky moves are always contagious. So I am constantly watching everything else.

Europe - It’s a bit sad we have had the Brexit vote in the UK, not because of the result but because of the shading, it has put on the reporting of Europe. In the salons of London, it is considered terribly bad form to point to concerns in Europe because having declared an avid will to remain in the EU casting criticism on anything European is seen as handing sharp object s to the leavers.

The AfD is rising in popularity in Germany (I read something that they are now the 2nd most popular party).  Italian elections are on the way and have all the hallmarks of doing a Brexit/Trump in providing a ’shocking' result as the concerns of the basic voter are dismissed as socially incorrect and troubles shuffled under the official carpet.  Greece has just failed to get its latest round of bailout money, Ok, they will but it is a reminder that the new glass tower of the European economy is built upon the limestone caverns of past debt mismanagement and a sinkhole could open up at any moment.

Back in 2016, I think it was for my ‘thoughts for 2017', I suggested that Europe problems could be obscured as long as economic growth kept everyone happy. This is what we have seen. The concept of default risk has evaporated and even Italian banks have been able to offload what was previously considered as toxic waste under a new wrapper of 'high yield' to private hands. Let's also not forget what Portuguese government debt is yielding. Less than US treasuries the last time I looked - now there IS a changed narrative.

But I can’t forget what is out there and how every thread of favourably reassessed credit risk leads to the door of the ECB.

The concentration of credit risk that has flown into the ECB is stupendous. Of course, it isn’t default risk because the ECB can QE until its heart content. But how content will that heart continue to be when Draghi is replaced by Darth Weidmann, commander of the Bundeathstar. I saw comments that the SPD approved of his appointment. That’s not a story. The story would be if Syriza approved of his appointment. He is a very clever man to move onto that throne under the cover of a benign economy, but even today the PMIs of Europe began to disappoint.

We tend to look at whatever is the current issue with respect to the world rather than in balance with the rest of the world. When the EU has a crisis, it’s just an EU problem and the US is just fine. When Britain has a Brexit wobble then it's Britain's wobble and the EU is just fine. Rarely are the comparative strengths and weaknesses observed and considered. One part of the equation is anchored whilst the other is considered the variable.

But maybe it isn’t. We think this a US-centric issue in the markets but we must watch out and be impartial in our judgments. Though we have global growth masking other problems, once the problems arise, global growth can collapse.

I am still playing the macro short on risk but am desperate for low-risk yield. I just think that all risk is priced too low as we enter the Great 'Global Risk Repricing’ which I hereby copyright as the GRR. Grrrrrrr indeed.

When it occurs the central banks are going to have a knife edge to walk between loosening, to counter the restrictive function of higher risk premia and tightening, to counter the inflationary effects we are already seeing. As they say with great comedy. "the secret is in the t t t timing",

If they get it right, they won't have to do anything as tightening of risk premier does their job for them. GRReat.

But the risk rolls on.

The diary of a messed up market day.



Well. Well Well. Or ‘three holes in the ground”, as my uncle used to say. That was a day.

The last two weeks have so far seen

Meltdown Monday
Turnaround Tuesday
We'll be OK Wednesday
Thumped Thursday
Found a base Friday
Make up your mind Monday
Trying Hard Tuesday

and today?
WTF Wednesday

I have to say that today was a hero to zero day for me in equity land. I played the CPI figure perfectly as stocks decided that the inflation story really. really is a concern. Until it isn't. And that ‘until it isn’t’ occurred about 15 seconds after maximum 'it is a really, really big concern'. That was when perfection vanished in a puff of humility and the ‘natural bounce up off the lows'  spent the rest of the day grinding higher up to new highs.

I am not too shy to own up to the stock shorts costing me money. I hate grinds, they are worse than sharp moves mostly because sharp moves engulf your emotions in one hit, whilst grinds tie you naked to a chair and beat your bits with a knotted rope until you are finally put out of your misery by the pistol to the head of a stop loss.

I think I might have been watching too much McMafia. Actually, that James Bond and Le Chiffre reference stemmed from a picture I saw of Macron in a Bloomberg article this morning and it just struck me how much Macron looked like Le Chiffre from Bond’s latest Casino Royale.






But I JUST KNOW that  US stocks will now tank. But if I don't understand why equities are going up then I must get out. Understand? That where your narrative fits whatever it is you want it to fit, but unless someone takes a 3ft pipe bending machine to the current narrative of ‘it’s inflayshun innit’ to make it fit with today’s moves then I am afraid this narrative is broken

We are getting through narratives faster than plates at a Greek restaurant.

I fell for that inflation one I really did. I even thought about what would do well in an inflationary world and thought.. hmm stocks could do well in an inflationary world because they hold tangible assets that are inflating so the value of them must go up against a deflating USD. Unless they own large amounts of debt and the cost of funding that goes up faster than the inflating asset values. I then thought this is getting complicated as I'll need to know the debt levels of the companies and if they are fixed or floating against which benchmarks and which currencies and where their manufacturing vs sales is and and ...  and then I stopped. It was all too much.

I'd wandered into this because my favourite dodgy high beta oil stocks that went to cash like everything else on the 12th Jan, might be worth buying again as I think we might be near the end of the oil dump. Have you noticed how correlated it is to SPX price moves?

But the problem with my dodgy oil stocks is that they have large loads of debt and funding that, relative to where rates were a month ago, would mean that oil will have to be a lot higher than its last recent peak. So I haven't bought them. I just bought oil instead. It’s always worth remembering that if you think something is going to go up or down, instead of getting clever with correlated stuff, just buy or sell the thing you think will go up or down. For example, with oil, don’t mess around with NOK/JPY FX thinking you are being clever, just buy oil.

The only consolation was a ‘that doesn't look right' enlarging of my long gold positions in the low 1320s and I did buy gold mining stocks, including some very dodgy ones. I even bought an ETF of gold miners (an ETF? In this environment? Are you mad?). It would be great if someone could inform all the goldbug loons of yesteryear, who took their evangelistic crusade to crypto-land, to come back because their one true Messiah is risen again. I never thought I'd miss them but we should point out that burying your gold coins in the backyard of your log cabin leaves your assets a little more accessible than down a phone wire that those pesky government agents, who you are sure you saw spying on you in the woods, could cut.

So that's been my day. I have ended it by kicking myself for not standing true to my initial beliefs that led me to eject all my positions in mid-January ahead of Martin Luther Turn Day. as defined in my post 4 days ago. 


1- Markets take off in January en masse in the direction set by all those ‘2018 trades of the year’. This sets consensus.
2- The week after Martin Luther King day, or Martin Luther Turn Day as I prefer to call it, together with the first expires, can often trigger a turnaround.
3- The start of February sees a peak crisis in something - EM, Bank Balance sheets, whatever.
4- This causes first round damage in the assets associated with the assumed crisis.
5- This causes losses which need countering by selling other assets that are in profit
6- This sees a cascade unwind in anything that is leveraged and heavily positioned.
7- Narratives chase price moves but are usually later proven to be incorrect.
8- These February washouts of the consensus trades of the year slowly settle down and reverse, leaving March as the time to really put on your trades of the year.


Good luck out there, I've had as much adrenaline as I can take for a fortnight. It made the skiing holiday look tame.

Saturday 10 February 2018

What happens next? The great global risk repricing.

Following swiftly on from the last post's synopsis of the changing narratives of last week, in the famous words of a UK TV sports quiz show, it's time for "What happen's next"? When a clip is shown and the contestants have to guess the, normally unlikely, outcome.

The clip shows US equities falling over, bashing heir head and looking dead only to spasm as we freeze the frame. So .. what happens next?

Friday felt like fear but the rally into the close makes this all the harder to call as both camps have ammunition.

For the bounce -

Nothing has really changed, the US economy is doing well, indeed it’s very success is what has triggered this fall.

Company earnings are booming and are not going to fall. In fact dividend yield on stocks has just gone up 10% due to the price drop. Thank you.

We needed a healthy correction. That was it. The weak holders are now out and will no doubt be sucked in slowly as prices rise again pushing them up further. Effectively we have more marginal buyers wanting to get back on the bus now they have been thrown off.

It isn't that bad, we are only back to last Noveber prices.

Why should overseas investors in overseas stocks be concerned about domestic US inflation? European investors in European stocks, where the ECB is still slow to drain liquidity, should see more reason to buy.

The size of that fall and the way it worked over the last two days saw the market move from 'unconcerned' to 'doubtful' to 'fear', only to see everything rebound into the close on Friday. We are done.

It was indeed just a volatility blow out, the ripples are settling.

It was a typical February positional wash out across all asset classes, hanging on an excuse of the labour data that tripped some ridiculous leverage in silly products. Over positioning of the year favorites has been rationalised and we can get on with it all again.


And for the trouble ahead -

It ain’t over until the fat cow squeals. the fat cow being the sacred cow position of short US treasuries.

If USTreasuies because what I saw as fear on Friday isn’t anywhere near fear yet and we are still in a complacent mode. this complacency can be reflected in headlines I saw on Friday saying we had ‘entered a corrective phase’ #. Entered a corrective phase? we entered a corrective phase two weeks ago! The sign should say; “Thank you for visiting corrective phase, only 2 days to meltdown, drive safely!"

Volatility lingers - from my last post on the last two week's action

One of the consequences of measures of volatility moving is that it affects how much leverage you can have in your portfolio. The lower the volatility in an asset the lower the assumption of risk in holding it. Value at Risk, or VaR models, dominate bank, traditional fund and, most importantly, algorithmic funds. When the number you use as a volatility input increase you have to reduce your holdings even if you still consider your base argument for holding them valid. It depends on the time frame of allocations, these can be instant in high-frequency models, to monthly for old-fashioned real money to really slow with retail. Value and volatility shocks linger in the darkest crevasses of portfolio management for ages. It's like oil on beaches after tanker spills.


That US Stocks are only back to where they were in November, meaning that losses for many are only lost profits not losses versus original investment, can be read as suggesting that many are still long.  I know this is nitpicking for mark to market, especially with a year-end real in between, but for retail it’s a psychological 'get out of jail' card. You can bet that every IFA out here is telling their clients not to worry. Probably because they haven’t yet worked out the reason to sell. This is a tell that there are many trapped longs out there praying for buyers to come back in.

But who? Real money funds have not liquidated on this and are probably as caught as retail. yet they have been sitting off record loads of cash so what are they going to spend to buy with. the wall of retail certainty will have dried up too. Of course, we will have the ‘just a dip’ buyers return but that doesn't mean it’s over. As we saw last Tuesday, buying dips and seeing a run-up doesn't mean you are right.

If this really is a US inflation story then why indeed are global stocks melting? The case for buying says that if this is US Centric that we need not fear in rest of the world. But the corollary is that as everyone else assets are dumping then this is not US-centric and the narrative is wrong.

The inflation story may just be the next narrative that will be questioned and thrown away as greater fear of unknown emerges.

This has become a global risk sell-off for equities and has started to become a general risk sell-off, but rather than looking at my usual ‘February, favourite trade squeeze’ what if this is something else?

What I am suggesting -

My best case is that no narrative can be ignored and all have their strengths.  But instead of them each being a separate diagnosis of different potential diseases they are all symptoms of a single greater one. They are all building into a great big superstorm of grief encapsulated in a super-narrative

Inflation, corrections, aspike in volatility (really an increased cost of insurance), problems in leverage, US bonds, problems in risk parity, China sell-offs, Junk bonds sell off, aren’t all separate but are all part of the same single story - the new super-narrative of ‘The great global risk repricing'

A sudden spasm of awakening to true risks may now be underway.  For years we have been saying that credit is too cheap and that junk bonds are way too expensive and that leverage has been practically free. I hate to hark back to QE, as we know that it has spawned a rash of ridiculous pricing, but this, folks, could be the big one with regards to waking up and smelling the coffee. Free money does not mean any risk.

This reassessment of risk perceptions can also include US Treasuries. If there is a chance that they are no longer the ultimate safe haven then the schism would have dire consequences for the stability of current investment theory. No, I am not saying that US Treasuries aren’t safe as houses, I am saying that all you have to have is people questioning them for problems to kick off as soon as Monday.

And that is why waiting for bonds to go up to know if this is over is all the more important, If they don’t then it is really bad news.

Most notably,  the popular position of short USD hasn't really seen much of an unwind but it should be consdiered as part of the short UST trade. This is not about rate differentials anymore, as we have seen the divergence of rate difererentials vs FX widen for the pat few months, but about underlying trust in the US to manage its affairs. It's part of the risk adjustment as the US and US has moved a notch right along the scale between Switzerland and Zimbabwe.

So what do we do? the trader in me wanted to buy on Friday, so i did, but the pragmatist thinks this is far from over.



I will run my long with a trailing stop ready for part 2 as so far that may have only been part 1.i and 1.ii.

I can't help but think that gold is looking exceedingly attractive.

The changing narratives of a market dump.


It’s February and I have been using Twitter more than the blog as, in effect, most of my thoughts are pretty simple and don’t need expounding but it is probably worth pulling everything together for the record and to evaluate the 'what happens next'

As regular readers know I have a regular concern about the way markets start new years, which can effectively be summarised

1- Markets take off in January en masse in the direction set by all those ‘2018 trades of the year’. This sets consensus.
2- The week after Martin Luther King day, or Martin Luther Turn Day as I prefer to call it, together with the first expires, can often trigger a turnaround.
3- The start of February sees a peak crisis in something - EM, Bank Balance sheets, whatever.
4- This causes first round damage in the assets associated with the assumed crisis.
5- This causes losses which need countering by selling other assets that are in profit
6- This sees a cascade unwind in anything that is leveraged and heavily positioned.
7- Narratives chase price moves but are usually later proven to be incorrect.
8- These February washouts of the consensus trades of the year slowly settle down and reverse, leaving March as the time to really put on your trades of the year.

With this in mind, I approached the third week of January with huge caution, switching holdings to cash, but Martin Luther Turn Day came and annoyingly it didn’t produce the falls, which was FOMO painful. However, month-end was looming and it wasn’t hard to calculate that, with bonds having fallen and equities have risen so much, rebalancing of assets in funds was going to see some very large selling of equities and buying of bonds.

The large size of equity selling occurred in the days running up to the end of the month but there didn’t appear to be the bond buying. However, the narrative of ‘just month end’ still accommodated the equity move leaving those long excused from their positions.

But the 'end of month’ narrative had an expiry date - the end of the month - and though this had passed we saw no bounce in stocks and the amplitude of intraday swings in equity prices was picking up (normally a turn signal).

Friday morning had me scratching my head as to why traded volatility wasn’t rising


We didn’t have to wait long. The US data showed a growth in wages. This flickered like a force 4 tremor on the seismometers along the San Andreas fault of inflation concerns. Bonds sold off again and stocks fell heavily, with inflation concerns triggering ‘just stop losses’ as the inflation story had been a back-burner narrative for a while. However, we know that ‘just stop losses’ is on a par with quoting Fibonacci levels in the league of ignorance of real reason.

With both bonds and equities lower, attention turned to the 'risk parity' sector with it now being blamed for the stop loss action. Risk parity funds switch between bonds and equities as historically when one falls the other rises, hence keeping risk levels constant, but now we had bonds and equities falling sharply. So, it was assumed, it must have been them. Even volatility was polite enough to move with VIX a whole point and a half up from 13.5 to 15.

Now a quick brief here to anyone reading this who is scratching their heads over what this volatility product thing is. Experts, please jump this.

Volatility is a mathematical measure of how fast and far a price moves. It is a historic measure as you need to know how far and fast something has moved to work out how far and fast it has moved.
But volatility is also the key ingredient to pricing an insurance policy. If you know how far and fast something has moved in the past you make ASSUMPTIONS as to how far and fast it will move in the future. This assumed future volatility, though psychologically referenced through price anchoring to past volatility is basically an informed guess.
The maths used to calculate insurance policies or options as we like to call them in finance, the Black-Scholes model, can pin down every variable (Exercise price, forward prices, interest rates, discount rates, time, etc) but there is always an unknown variable (otherwise we are saying the future is certain) and this unknown variable all boils down to one number called 'implied volatility’. And this is what is traded in options markets. 
The word ‘implied' should be the clue to the danger here because as this is the only effective unknown the equation, should the price of the option change, even though basic demand (say a corporate wants to hedge a large overseas future payment) then the implied volatility changes too. This does not mean that actual price volatility of the underlying asset will change even though the implied volatility has. Nor does it mean that, as volatility is so closely linked to implied probability in the equations, that any actual probabilities have changed. 
Basically, it may IMPLY that probabilities have changed but it doesn't mean they actually have. It is worth comparing this to CDS pricing where the same calculations are made as it too is an insurance product, where many confuse CDS prices with the actual probability of default.
So with this in mind we look at the next derivative of implied volatility - which we have already decided is a derivative of the maths of guessing where prices will be in the future - the VIX. This is an index of lots of specific implied volatilities from lots of different assets in different time frames. If you think it is simple then just look here to correct that view. Yet this index is bet upon in its pure form through a futures market and as soon as something can be bet upon as a future it is assumed to be clean and pure. As this future can be bought and sold and held in a portfolio the dangerous next step is to consider it as an asset rather than the complex hypothetical maths derivate of the future unknown that it actually is.
As this comfort grows funds are structured to hold these futures in ETFs and ETNs. and if the movement in these ends seems pretty small they are geared up by leverage to multiple factors in specialist ETFs. Finally, a product is offered a product that goes up when implied the VIX goes down - the XIV (as in VIX reversed, not the French king Louis XIV, though they both suffered excruciatingly painful deaths). 
As stock prices had been rising strongly for a year demand for hedges against them falling had dropped. And so implied volatility fell too. (I won't get on to the asymmetric behaviour of volatility but it is worth bearing in mind that historic volatility can be as high on strong up moves as it can be on down, but the way people associate implied volatility is that it goes up on price falls). 
This created a trend which was observed as an trend in a true asset and was sold as such. As soon as past performance can be cited as a reason to buy then a dangerous feedback loop evolves (see Bitcoin). Money poured into the trend with very little idea of what was actually being bought, indeed funds themselves started to sell volatility to increase there own performance having missed out on the stock moves. 
We even saw people study these products with technical analysis like an asset, adding trend lines, oversold/overbought lines and Fibonacci levels (see above) to it. The distance they had stretched from the reality of what drove these things had reached parsec levels. But it had already established itself as a legitimate hedging tool and had become embedded in countless financial products and bank and fund positions.   

So what happened?

Monday saw the dormant VIX crack as leveraged trades in toxic products cascaded down the tree of hedges into ‘have to sell stocks’ which just pushed up volatility making it all worse.Volatility skyrocketed, both implied and actual. I am not going to quote a number it hit because different time frames have different values and I could just pick, as the press does, the most impressive. They were already performing statistical crimes by reporting that volatility had gone up 100% when it had gone up from 14% to 28% (that's up 14%).

Even with this massive 10% move in stocks the narrative of explanation was still not concerned that this was anything to worry about in the longer term. It had moved from 'just month end', through 'just stops on wage data' to 'just an explosion in mad dog leveraged lunatic esoteric products'.

Which is somewhat ironic as on this basis it would be clear that the crash had been caused by everything that posts 2008 enforced regulations and been put in place to rid us of - ridiculous leverage in products that are toxic, bought by punters who have no clue and sold by spivs who point at past performance to sell them. It was textbook.

Tuesday saw the ‘volocaust’ settle down as volatility products were now the assumed culprit and this wasn’t a reason to sell global risk. But even though VIX, which was by now as keenly watched for direction as stocks themselves (another example of the tail wagging the dog). A rally in stocks was assumed to be great news that everything was settling down and the 'volocaust' was passing, but massive moves up in the underlying asset can be as representative of chaos in a volatility market as much as down, as delta hedges in the underlying get more desperate. A rapid up move did not mean volatility was falling even if implied volatility was.

Global assets were now wobbling. If this was indeed just an esoteric product wobble then why on Tuesday night / Wednesday morning did Chinese and Japanese stocks put in such a battering? Moves like that in China, without anything else to look at, would normally of themselves because for a mini global rout (2015) but these were being studiously ignored.



Wednesday saw rallies, which made my China theory look iffy and reinforced the 'it's just vol' story - until the close, which was dreadful. Stocks were being dumped again.

One of the consequences of measures of volatility moving is that it affects how much leverage you can have in your portfolio. The lower the volatility in an asset the lower the assumption of risk in holding it. Value at Risk, or VaR models, dominate bank, traditional fund and, most importantly, algorithmic funds. When the number you use as a volatility input increase you have to reduce your holdings even if you still consider your base argument for holding them valid. It depends on the time frame of allocations, these can be instant in high-frequency models, to monthly for old-fashioned real money to really slow with retail. Value and volatility shocks linger in the darkest crevasses of portfolio management for ages. It's like oil on beaches after tanker spills.

Thursday saw another leg downwards as things were now starting to look global. China was still steadily falling, FTSE was now down 10% off the highs, the DAX was in serious trouble (the darling of the ‘euro-uber-alles' trade) and it was all starting to look as though we had a big mismatch between action and explanation. When that occurs things get really messy. Not understanding why something unpleasant is happening is the gasoline on the fire of fear.

Friday was interesting. What appeared to be fear emerged properly with even the 'just a healthy correction’ crowd looking a bit like the Monty Python Black Knight, yet the markets bounced into the close. There was no new news. Price is news (PIN).

----------------

Stepping back from all of the micro of the week, we could fit all of the above into the classic layout of the original 8 steps of a February wash out. It starts as a US concern, has accelerated and is now hitting global risk appetite with apparently dissociated assets in far off places being sold.

‘Inflation' may now be sprawled in colour on the billboard outside the cinema but inside the show is a classic black and white blow out of consensus trades.

The big what 'happens next? ' I'll ponder over in the next post "What happens next? The great global risk repricing." (Now posted here) but I am far from sure that this is over.

But before I go I’m going to be a bit unkind. But it does need to be said. There a lot of people out there who pride themselves on analysing the minutia of finance, looking for clues as to the next nuance of price moves or the odd basis point arb between trades, or clever sector switches, or curve trades. So it is with an evil gloat I see their detailed embroidery get burnt up in the house fire caused by the gallon of gasoline left in the oven that they failed to spot. At the end of the financial day, you are judged on PnL not PhD
