According to FINRA, Joseph Adam Eisler of East Hampton, New York was barred from association with any FINRA member in all capacities for allocating IPO shares to a customer in exchange for a portion of the customer's profits.

Eisler and the customer agreed that Eisler would receive a portion of the customer's new issue profits through additional, unearned commissions charged on subsequent, unrelated transactions. Over more than 100 new issue allocations, Eisler received more than $120,000 from the customer through this undisclosed arrangement.

Eisler never disclosed the profit-sharing agreement to his member firm, nor did he obtain prior written authorization from the customer or the firm. While he shared in the customer's gains, Eisler did not compensate the customer for any losses and made no financial contribution to the customer's new issue purchases.

The conduct violated rules prohibiting registered representatives from sharing in customer profits or losses without proper authorization and disclosure. Such arrangements create conflicts of interest—when a broker profits directly from a customer's gains, it may influence which securities the broker recommends.

Additionally, for eight years, Eisler exchanged hundreds of text messages on his personal phone related to securities business, including communications about the profit-sharing arrangement. This violated firm policy requiring business communications through approved, archived channels. Each year, Eisler falsely attested to his firm that he complied with this policy. By using personal text messages, the firm could not capture or review his communications.

For investors, this case illustrates the importance of understanding how your broker is compensated. If you suspect a broker is participating in your profits outside normal commission structures, this should raise concerns. All compensation arrangements should be disclosed and documented.
