Realized Stock Volatility Plunges
Did ETFs play a role in huge price swings?
"One of the most remarkable characteristics of the '08/'09 market crash was the daily volatility that occurred. On December 8, the average absolute daily change of the S&P 500 over the last 50 days reached a record 4.02%! With the entire US stock market gaining or losing 4% to 5% of its total value on a daily basis for two months, how did any of us stay sane?
"Since peaking late last year, however, the average daily change for the market has cratered. As shown below, over the last 50 days, the average absolute daily change for the S&P 500 is now under 1% at 0.87%. This is the lowest level since July 23 of last year. Markets fall much faster than they rise, so it's no surprise that this number has gone down significantly as the S&P has risen 52% off of its lows. But many investors also believe that the 2x and 3x long and short ETFs played a role in the huge price swings that we saw. Going forward, we wonder what impact the banning of leveraged and inverse ETFs by brokerages will have on market volatility."
That .87% neatly translates into something like a 14 volatility, which is probably not surprising to you if you read here much in that I dedicate every other post to noting the pathetic lack of stock motion.
But what of these 2x and 3x Bogeymen Bespoke speaks of? Remember way back when, they were destroying America?
Now? Well they still exist, and we managed to have a monstrous rally anyway. The only time you hear anyone mention them is in relation to a lawsuit. As in, "The market imploded in fall 2008, and all my -2x and -3x ETFs went lower anyway."
With the benefit of hindsight, it's probably safe to say they work both ways, both in terms of their effect on stock prices and volatility. Remember the "rebalance trade"? That appeared to add volatility as it moved the ETF further in the direction of the move that day. But on the flip side, the Inverse ETFs become a de facto alternative to an actual put, and can lower demand for put protection and ergo, lower implied volatility.
Whatever the case, you can see the average daily dollar volume here in SKF has plummeted. The stock has halved since May, and volume has as well.
At the end of the day, you can probably surmise that their mere existence hardly prevents market rallies.
