Ex-Goldman Sachs Programmer Found Guilty
Readers twoallbeefpatties and ngrier wrote in essentially simultaneously about the guilty verdict in the trial of former Goldman Sachs computer programmer Sergey Aleynikov. We've discussed the case several times before. The trial itself was sealed from the public to prevent discussion of GS's high-frequency trading system. Reader ngrier summarizes: "After just three hours of deliberation, the jury found Sergey Aleynikov guilty of intentionally stealing proprietary Goldman Sachs code. As he had admitted copying the code as he was preparing to join a startup competitor in 2009, the case hinged on the intent. He faces up to 10 years in prison."
High frequency trading actually facilitates more accurate pricing of securities because of the liquidity it introduces to the market. The benefit of accurate pricing is hard to explain fully without getting deeper into the economics of markets, but it's definitely there. The animosity you raised is probably due to a perceived lack of contribution (no tangible products produced). But actually, facilitating better pricing will route investment into areas that deserve it (e.g. to the guy who produces 2 potatoes per unit resource instead of 1.5 potatoes). The sum effect of these actions is a raised social utility.
