Machines Had Their Fingerprints All Over a Dow Rout for the Ages

(Worthy News) – Risk parity funds. Volatility-targeting programs. Statistical arbitrage. Sometimes the U.S. stock market seems like a giant science project, one that can quickly turn hazardous for its human inhabitants.

You didn’t need an engineering degree to tell something was amiss Monday.

For 15 harrowing minutes just after 3 p.m. in New York a deluge of sell orders came so fast that it seemed like nothing breathing could’ve been responsible.

The result was a gut check of epic proportion for investors, who before last week had been riding one of the most peaceful market advances ever seen. The S&P 500, which last week capped a record streak of never falling more than 3 percent from any past point, ended the day down 4.1 percent, bringing its loss since last Monday to 7.8 percent.
