Unauthorized trading occurs when the stockbroker/financial advisor fails to obtain your permission to purchase or sell a security. When an unauthorized purchase or sale has occurred, it is important to complain immediately! The best way, if not the only way, of knowing whether unauthorized trading is occurring, is to open one’s mail! Many investors do not open the envelopes they receive from their brokers. Those envelopes may contain “confirmations,” documents reflecting purchases and sales. Please open your mail!
