.VIX 5D mountain The VIX is well off its highs from Monday as the stock market tries to claw back its losses. The VIX, often called Wall Street's "fear gauge," reflects expected volatility over the next 30 days based on the price of S & P 500 options. "Excluding the current shock, there have been 39 VIX spikes to above 35 in our empirical analysis since 1999. Market shock of this magnitude happens on average more than once per year, but is unlikely to sustain. The lingering question now is whether the concerns that pushed the market into a cascade of selling are alleviated," Krosby said.
