Courts often entertain insider-trading cases where individuals are accused of using material non-public information (MNPI) gathered from their employers to trade in other companies' securities. See, e.g., SEC v. Huang, 684 F. App'x 167 (3d Cir. 2017) (unpub'd) (former employee at a large bank misused customers' credit-card transaction data to guide trading in merchant companies' securities).
