Testing The Sacred Cow

Ok, so this week is going to be a test.

Recent history has taught us that every vol. spike is an alpha opportunity. Every dip is a buy. The rapidity with which vol. spikes have “mean reverted” has increased over time…

VIX

… and indeed, that’s one explanation for elevated vol. of vol. (which, you’re reminded, was trending higher relative to the VIX well before last week, when the risk-off mood caused VVIX to hit a post-yuan-deval high):

So, is “this time different”? That is, have we finally come to the end of the “mean reversion” regime in vol. and if so, does that presage the imminent demise of BTFD, that most sacred of sacred market cows?

We’ll find out, but in the meantime, here’s a little history lesson on this from Bloomberg’s Cameron Crise…

Whenever stocks sell off these days, you can usually be sure of two things. Bears (many of whom are long-standing) will say that this is just the tip of the iceberg, and bulls will say that you need to take advantage of the buying opportunity. Over the last few years, the bulls have been proven correct. Indeed, since the early 1990s buying into the current setup has generally been quite profitable. However, there are a few reasons to believe that this time may in fact be different, at least when it comes to instant gratification for dip-buyers.

  • Over the last few years, and particularly in 2017, it has paid off to fade equity weakness more or less immediately. Mean reversion in low volatility environments means that any spike in vol is a buying opportunity.
  • Bloomberg analyst Thomas Cuppernull identified some simple criteria that fit the current environment very well. Specifically, a trailing one-month average VIX reading below 15 and a three-day move in which the level of the VIX rises by at least 40%. Since 1990 there have been 17 occasions on which these criteria have been met, with 11 of them coming since the start of 2014. (There are three instances in which the criteria have been met separately within a few days of each other.)
  • On balance, the performance of the S&P 500 subsequent to such volatility spikes has been excellent. The average one-month return has been 1.3% with a median of 1.5%. There have only been two occasions in which the index has ended up lower after a month — a pretty stunning hit ratio. So should investors be loading up the boat on stocks?
  • “This time is different” is famously one of the most expensive phrases in finance, but perhaps this time really is different — at least in the short run. Short volatility strategies are more deeply embedded than has been the case in recent years. The last CFTC report showed that nominal speculative net shorts in VIX futures were at an all-time high.

[Aside: that position was pared a bit in the week through Tuesday – but just barely]

  • While the short was not quite as extreme as a percentage of the open interest, even that ratio is higher than all but one of the prior vol spikes in our sample.
  • Moreover, the technical picture, particularly for technology stocks, remains negative. And the stock market drawdowns this year remain extraordinarily small by the standards of history. The real “this time is different” bet is that stocks continue to rally more or less in a straight line.

  1. When your economy doesn’t have to account for its debt, or have a viable way to repay that debt – ever – things can only go up. Up – until the Wile E. Coyote market investors discover that it too has long since run past the edge of the fiscal cliff and is now being supported by nothing more than freshly printed currency floating on thin hot air.

  2. Each day I count as one closer to that cliff.
    Tangible, real assets bought with fiat funds are my TTID.
    Trading on the fiat currency to add quality to my life is my goal.
    I have been in this rodeo for the last 37 years.
    Time to change direction, and saddle a new ride.
    LOL.
