Unless you provide your broker with discretionary authority, in writing, a broker requires your prior permission to effect transactions in your securities account.
It is well-settled that "claims under Rule 10b-5 arise when brokers purchase or sell securities on their clients' behalf without specific authorization."
For example, a claim for unauthorized trading, which occurs when a broker intentionally places trades without obtaining the customer's approval, historically has been well-established under Rule 10b-5.
"By definition, a broker who is liable for making unauthorized trades makes them without the customer's authorization."
However, if you fail to act, or fail to mitigate your damages by complaining or seeking to undue any unauthorized transaction, you may lose your right to complain later. Investors who repeatedly accept confirmations and statements disclosing transactions with brokerage firms, and fail to complain about these transactions within a reasonable time after discovery, are barred by waiver, estoppel and laches from later assertion of wrongdoing.
However, if you believe that you may have been the victim of unauthorized trading by your broker, contact us for a free evaluation of your claim.
