Knight Capital
The Jersey City wholesale market maker, founded in 1995, that built the largest US business in filling retail stock orders by paying brokers for them — and then, on the morning of 1 August 2012, lost more than $460m in about 45 minutes (SEC order, 16 Oct 2013; Knight's own early estimate was ~$440m pre-tax) when a partly deployed software release reactivated retired code on one of eight servers of its order router, SMARS. Trying to fill 212 small retail orders, the router sent millions of child orders and obtained over 4 million executions in 154 stocks for more than 397 million shares, leaving Knight with ~$3.5bn of unwanted long positions and ~$3.15bn of unwanted shorts (SEC). A $400m rescue led by Jefferies five days later kept the firm alive but gave the rescuers roughly 73% of it on conversion (reported); within a year Knight had merged with the high-frequency trader Getco to form KCG Holdings (1 Jul 2013), which Virtu Financial bought in 2017 for ~$1.4bn. For a trading book Knight is the cleanest case of the edge equation's survival factor failing for operational, not market, reasons: a real, durable liquidity-provision edge, erased in under an hour by a deployment error and the absence of a hard pre-trade limit. It was also the SEC's first enforcement case under the market access rule (Rule 15c3-5), with a $12m penalty.
