Red Flags and Investor Concerns
Even if you have not filed a formal complaint, there are several warning signs every investor should know if they worked with Jacob Harper:
-
Borrowing from clients can lead to conflicts of interest and potential misuse of funds.
-
Opening or managing accounts outside firm supervision can indicate “selling away,” a violation that often results in investor losses.
-
Frequent firm changes—from Wells Fargo to D.A. Davidson and finally LPL Financial—can signal underlying issues with compliance or supervision.
-
Regulatory sanctions without client complaints can still indicate undisclosed risks or policy violations.
If you received investment advice, account management, or portfolio recommendations from Jacob Harper, it is essential to ensure those investments were handled according to FINRA and SEC rules.
