Ethical Decision-Making in Investment Analysis

Jamie is an investment analyst with a well-known investment firm. During her research for a new project, she discovers that a company she is analyzing is set to release unexpectedly strong quarterly earnings reports. However, Jamie has signed a non-disclosure agreement (NDA) with the client's competitor, which prohibits her from sharing any non-public information regarding that industry. Despite her NDA, she is tempted to inform the competitor of the company’s upcoming positive earnings to help them strategize for their own investment decisions.
