This practice often results in significant financial losses for the client, while the stockbroker benefits from the commissions generated. Violation of Blue Sky laws refers to the breach of state securities laws designed to protect investors from fraudulent securities practices. These laws vary from state to state, but generally aim to ensure the fair and equitable treatment of investors and prevent fraudulent activities in the securities' industry. Breach of fiduciary duty occurs when a stockbroker fails to act in the best interest of their client or puts their own interests ahead of the client's. Stockbrokers have a fiduciary duty to provide suitable investment advice, disclose material information, and act with honesty and loyalty towards their clients. Breaching this duty can lead to significant financial harm for clients.
