If you are a broker, and when you have insider information that has negative implications on a stock your company told you to buy, Are you required to execute the trade?
I would say yes. Purely a code and standards issue - you cannot act upon or cause others to act upon material non-public information. -Stillwagon
ideally you would immediately contact the company’s management and encourage them to make the info public. If they agree your firm will change their buy order themselves. If they didn’t you would have to execute the trade
