Signs Investors Should Look Out For About Their Brokerage Accounts

As an investor, there are a few signs that you should look out for if you believe you may have a claim against your financial advisor. These signs could potentially indicate misconduct, negligence, or investment fraud. Investors are encouraged to contact our firm immediately if you have experienced any of the following:

  • You have substantial losses in your investment accounts
  • You received a call, email, or other communication from your broker’s supervisor or manager regarding your portfolio
  • Your broker misrepresented investment opportunities, or failed to disclose details about investments
  • You notice unauthorized transactions in your investment accounts
  • Your broker is not returning your calls or emails
  • You filed a complaint with your brokerage firm that has not been resolved
  • You see a mistake on your statement, or receive a fraudulent statement

Some investors have close relationships with their brokers due to the time and trust built over the course of their investment relationship. However, it is crucial to remember that financial decisions should be based on careful analysis and due diligence rather than solely relying on personal relationships.

Engaging the services of an experienced securities attorney to evaluate your specific circumstances is strongly advised.
