Will Robot Traders and Rogue Algorithms Take Down Wall Street?
We already know that supercomputers, sophisticated algorithms and mathematical models are at the very heart of the modern financial markets. Now, with l'affaire Knight Capital we've just seen how robot traders and rogue algorithms could potentially take down Wall Street. In a span of less than an hour, a rogue algorithm programmed to exploit market efficiencies by buying and selling stocks repeatedly for profit actually inverted the logic of Wall Street: instead of buying low, selling low, the algorithm began to buy high, sell low. All told, the rogue algorithm resulted in a $440 million loss for Knight Capital, causing many to question the state of our modern financial markets.
