You are an investment banker in a major US firm and receive info from time to time from corporate clients re: takeover activities. A friend who is a securities trader in another brokerage firm has suggested to you if you are willing to provide info on upcoming takeovers she will forward info to certain individuals who could make stock pruchases through various accounts and make sales once the takeovers are announced, producing quick profits which would be shared with you. What are the legal and ethical aspects to be applied here?
