Stock 'fear gauge' flawed, Citi equity trading chief says
"A big mistake the market makes is looking at the VIX as an indicator of stock market risk. Why? Because it's an asset class and it's more traded for yield than protection," Pringle said. "The growth of structured products around VIX drove that move. In most cases, the VIX is sold to generate yield but during some stress periods, the weakness in the spot level triggers significant computer-generated technical buying from these products," he said. Pringle cited Citi trading strategy research showing tens of billions of dollars' worth of assets under management linked to the VIX through structured notes, which had to be rebalanced to reflect actual market moves. This dampened volatility, he said. The Citi data showed these VIX-related contracts make up about 34 percent of overall volatility trading on the S&P 500 and as much as 44 percent of the short-term, 2-month volatility."
