&gt;Here, Bonan Huang and Nan Huang allegedly got the information from their employer, Capital One, which was supposed to have exclusive use of the -- hey, wait a minute, does that mean that Capital One was allowed to trade on this data for its own profit? Wouldn&#x27;t that be amazing? Surely the answer is no: I assume that Capital One signed agreements with retailers (or rather, with Visa and MasterCard, which signed agreements with retailers) in which it promised not to disclose transaction data, or use it for nefarious purposes. Really anyone who used this data would be misappropriating it from, ultimately, Chipotle. Which gets to keep its sales data to itself. Except once a quarter when it releases that data and the stock jumps.
