Explaining stock market volatility

They say a picture explains 1,000 points…

…the lighter side of market volatility which in reality is probably not far off the mark.

FNF Media wrote back in October 2015,

ETFs are hitting the market faster than the dim-sum trolley can circle the banquet hall. Charles Schwab, in the 12 months to July 2015, saw a 130-fold preference of ETF over mutual funds given their relative simplicity, cost and transparency….

…ETFs, despite increasing levels of sophistication, have brought about higher levels of market volatility. Studies have shown that a one standard deviation move of S&P500 ETF ownership as a percentage of total outstanding shares carries 21% excess intraday volatility. Regulators are also realising that limit up/down rules are exacerbating risk pricing and are seeking to revise as early as October 2015. In less liquid markets excess volatility has proved to be 54% higher with ETFs than the actual underlying indices. As more bearish market activity has arrived since August 2015 we investigate how ETFs may impact given a large part of recent existence has been under more favourable conditions…

CEO Larry Fink of Blackrock, the world’s largest ETF creator, has made it clear that
leveraged ETFs (at present 1.2% of total ETF AUM) have the potential to “blow up the whole industry one day.” The argument is that the underlying assets that provide the leverage (which tend to have less liquidity) could cause losses very quickly in volatile markets. To put this in perspective we looked at the Direxion Daily Fin Bull 3x (FAS) 3x leverage of the Russell 1000 Financial Services Index. As illustrated in the following chart FAS in volatile markets tends to overshoot aggressively

…The point Mr Fink is driving at is more obvious in volatile markets, the average daily return is closer to 10x (in both directions) than the 3x it is seeking to offer. This is post any market meltdown. On a daily basis, the minimum and maximum has ended up being -1756x to 1483x of the index return, albeit those extremes driven by the law of small numbers of the return of the underlying index. Which suggests that in a nasty downturn the ETF performance of the leveraged plays could be well outside the expectations of the holders.”

FNF Media has said for many years, where CDOs and CDSs required the intelligence of a mythical hermit atop a mountain in the Himalayas to understand the complexities, ETFs are the complete opposite. Super easy to understand which inadvertently causes complacency. Unfortunately, as much as they might try to do as written on the tin, the reality could well turn out to be the exact opposite.
