Allegations of misrepresentation by a financial advisor typically mean the broker provided false or misleading information, or failed to disclose crucial details about an investment—such as the risks, fees, or performance history. In the context of bonds and options, this can involve omitting key information about liquidity, risk level, or how the investment actually works. Misrepresentation can lead to significant financial losses, especially when the client relies on inaccurate or incomplete advice to make investment decisions.
