There has been lots and lots written and said lately about systemic risks created by exchange-traded funds (ETFs), so I won’t belabor that here. I will, however, add this nice graphic from JPMorgan showing the rise in futures & ETF volumes as % of cash equity volumes. As the JPM folks rightly point out, if the market were just broad-index ETFs then the S&P 500 individual equity correlations would be 1.0 ….
To be somewhat more practicallly-minded, how can you not be a seller of implied correlation one- or two-years out at this point? Hello? This can’t continue, so it won’t. [-]
