I just read a great article about these two people that worked at Capital One credit cards. Their job was to monitor for credit card fraud. Being enterprising and innovative what these two did was write queries to see how many people bought Chipotle, and you guessed it, they did some market analysis and made a killing in stocks. Looks like they did this for a few different companies. Needless to say they were charged with inside trading. I can't help but wonder though, had they been able to work instead on just market data would they have been as successful in seeing trends? I doubt seriously this is the last we will hear about this kind of data mining. There are so many industries where things like this could happen. Now had this been the company owners instead of employees would it have been misappropriation?
