Rise of the Algos – Knight Capital and the Inevitable Catastrophic HFT Market Meltdown
By mw | Related entries in Bad Decisions, Banks, News, Regulations, Wall Street, WTF?A High Frequency Trading proprietary algorithm crafted by highly compensated brains-on-sticks and nurtured in the bowels of an investment bank escaped into the wild. From its carefully co-located massively parallel high speed trading computer it emerged to wreak havoc on the financial markets. In this case, it was a happy ending. The algo turned on its master and sucked the very life blood out of the firm that deployed it.Once Knight Capital’s algo was identifed as the culprit, the public company’s stock was slashed by 1/3 – a $300 million market cap haircut decapitation. That was Wednesday before we knew how much the algo lost on the trades. On Thursday morning KCG’s stock was slashed in half again when the trading loss was being reported at $440 Million. The incident is yet another lights-flashing, klaxon-blaring warning signal that competing HFT algorithms operating with the speed, size and complexity that are commonplace today cannot be adequately regulated, tested, or managed. Their interactions with each other cannot even be fully understood or predicted.
