Particularly, a National Securities Corporation client filed FINRA Arbitration No. 23-00601 about Sean Hosein. Mainly, the client alleged that Hosein made unsuitable recommendations involving pre-IPO alternative investments. According to the claim, the securities broker also generated excessive commissions from 2016 through 2022. Because of this, the client allegedly incurred damages tied to those alternative investments. As a result, on March 26, 2025, National Securities Corporation settled this matter by paying the client $1,250,000.

Unsuitable advice may occur when a recommendation exposes a client to risks, illiquidity, or costs that are inconsistent with the client's profile or investment goals.
