Borrowing can increase gains, but it increases losses too, and you can lose more than you put in. If the value of the account falls, the firm can demand more money or sell your securities, sometimes without notice. Losing money on margin is not, by itself, a claim. The key questions are whether borrowing fit the investor and whether the professional who recommended or approved it fulfilled their duties.
This May Not Be Your Fault
A margin account often opens with a stack of paperwork, and many investors sign it without realizing what it allows. If you did not fully understand that you were borrowing, or what could happen if prices fell, you are far from alone.
That is why the rules put duties on the firm. Under FINRA Rule 2264, a firm must give an individual investor a separate margin disclosure statement before opening a margin account, and again at least once a year. A broker who recommends borrowing must also have a reasonable basis to believe it serves your best interest under Regulation Best Interest, which means weighing your finances, your goals, and your ability to absorb a loss. When that does not happen, responsibility may belong with the broker and the firm.
