Algorithms Have Their Fingerprints All Over this Rout

The markets had a wild day yesterday. Big loss at open, almost back to even, then a really steep fall, and finally, a little rally to close. Bloomberg says that the trading activity has all the telltale signs of algorithms wreaking havoc. For 15 minutes just after 3 pm, the volume of sell orders was so quick and so voluminous that nothing alive could have possibly executed them. The market tanked, plunging to a 1,597-point loss. Interestingly, the involvement of algorithms might help to assuage some fears, as brokers are using that dimension as a way to calm human investors that this was not an all out emotional panic, but rather technology gone wild.


FINSUM: So we know they are deeply ingrained and certainly going nowhere, but why, in principle, are non-human agents allowed to transact in markets? Market-making firms would say they add liquidity, but they certainly exacerbate, or even cause panic too.
