What Is Unauthorized Trading Of Stocks?

Unauthorized trading refers to a situation in which a broker buys or sells securities in a client's account without the client's permission. Brokers must obtain prior consent before executing any trade unless the account has been designated as a discretionary account, which gives the broker specific written authority to make decisions on the client's behalf. When a broker conducts transactions without that authority or outside of the agreed-upon terms, it can expose clients to unexpected losses and constitutes a violation of industry rules. This type of misconduct can be particularly damaging to elderly or vulnerable investors who rely on their broker to act in their best interest.
