This is probably going on right now in lots of other companies that have access to such data. We only hear about the ones that get caught. Seems like they didn't try too hard to cover their tracks. Just think about all the companies that have access to credit card data and all the people that are connected to those companies who could either be selling the data to others or trading on it themselves. Best thing to do to prevent this unfair advantage is releasing publicly available CC spend data.

> Best thing to do to prevent this unfair advantage is releasing publicly available CC spend data. Who releases it? Every credit card company? At what frequency? What if one of the nightly bulk loads into the transaction data warehouse fails with an integrity error, alerts the DWH team, is picked up by a junior person because of a staffing anomaly, who forces it through, and then the next day's data release is off by a couple of million, but the automated trading bots and manual trading desks don't know this, so they trade on this new signal... ....I'm sure you see where I'm going with that.
