I was surprised to see it, but this dropped a fair amount yesterday.
BBG: One-month skew, a measure of demand for options to protect against a drop in the S&P 500 Index, has risen from the lowest in a year to the 72nd percentile of observations, according to data compiled by Mandy Xu, head of derivatives market intelligence at Cboe Global Markets Inc.
“Friday’s selloff was meaningful in waking up traders to looming risks in the stock market,” Xu said by phone, referring to that day’s 2.6% drop in the S&P 500 and an almost 4.8% plunge in the Nasdaq 100 Index. “There had been a lack of hedging any downside risks after everyone was chasing the rally. But now we’re seeing a reversal on an index level, which signals investors see the potential for another leg lower in the market.”
