I genuinely think this is a grey area, and it's far from "insider" trading. Is it moral, I don't think so. Should Capital One sanction these employees, probably. But I think this is far from ilegal.<p>Huang and Huang had access to a db which is not open to everyone, granted, but they had to extrapolate the stock direction based on data from a subset (customers who buy Chipotle with a CC), of a subset (with a Capital One card)... and then compare that to analyst expectations, etc. but then, would it be insider trading if I stood outside a Chipotle polling customers who exited on the dollar amount spent? That is also proprietary information, and one I can use to trade stocks on. I'd like to know if they did any trades where the return went south. I know of sector investment funds which pretty much do this all day long, forecasting all sorts of industries, and it's not ilegal.<p>I'd like to know what others think.
