Friday also marked the simultaneous expiry of quarterly derivatives contracts tied to stocks, index options and futures, also known as "triple witching," which can boost trading volumes and exacerbate volatility.

The week started with investors' options positions leaning toward call contracts - typically bought to express a bullish bias, said Brent Kochuba, founder of analytic service SpotGamma. However, the S&P 500's failure to rise quickly eroded the value of upside call options, putting further downward pressure on the market, he noted.
