Bakhtiari & Harrison represents investors in margin trading abuse claims against broker-dealers and registered representatives in FINRA arbitration nationwide. Margin — borrowing against the value of securities in an account to purchase additional investments — amplifies both gains and losses, and can expose investors to catastrophic losses exceeding their original investment. When a broker recommends or implements a margin strategy inconsistent with the investor’s risk tolerance and financial situation, the resulting losses are actionable under FINRA suitability rules and California securities law. Ryan Bakhtiari served as Chairman of the FINRA National Arbitration and Mediation Committee from 2013 to 2017 and as President of PIABA. Investor cases are handled on a contingency fee basis — no recovery, no fee.

What is margin trading?

Margin trading involves borrowing funds from a brokerage firm, using existing securities as collateral, to purchase additional investments. Margin amplifies investment returns when positions appreciate — but equally amplifies losses when positions decline. Because the borrowed funds must be repaid regardless of investment performance, margin losses can exceed the investor’s original investment, resulting in a net deficit to the brokerage firm that the investor is personally liable to repay.

Margin is a legitimate tool for sophisticated investors who fully understand the risks and have the financial capacity to absorb amplified losses. It is not appropriate for conservative investors, retirees, or investors whose financial situation cannot tolerate the possibility of losses exceeding their principal.

Margin calls — how losses accelerate

When a margined account declines in value, the broker may issue a “margin call” — a demand that the investor deposit additional funds or securities to maintain the required margin level. If the investor cannot meet the margin call, the broker can — and typically will — liquidate positions in the account at current market prices to restore the required margin level. This forced liquidation frequently occurs at the worst possible time, locking in losses at market lows and preventing recovery.

The margin call mechanism means that a broker who implements a margin strategy inconsistent with the investor’s financial capacity is not just making an unsuitable recommendation — they are creating the conditions for forced liquidation and catastrophic, compounded losses that the investor has no ability to recover from.

FINRA Regulation T and margin requirements

The Federal Reserve’s Regulation T sets the initial margin requirement for securities purchases at 50% — meaning investors may borrow up to 50% of the purchase price of most securities on margin. FINRA Rule 4210 sets maintenance margin requirements — the minimum equity level an account must maintain on an ongoing basis. When an account falls below maintenance margin requirements, the broker can liquidate positions without prior notice to the investor.

Broker-dealers must comply with Regulation T and FINRA Rule 4210 in administering margin accounts. When a broker implements a margin strategy that violates these regulatory requirements — or when the firm’s supervisory system fails to monitor margin levels adequately — both the broker and the firm may face liability.

Frequently asked questions — margin trading

Can I have a claim if I signed a margin agreement?

Yes. Signing a margin agreement authorizes the broker to extend margin — it does not authorize the broker to use margin in a way that is unsuitable for your financial situation or inconsistent with your investment objectives. If the broker’s margin strategy was unsuitable for your profile, you have a viable FINRA arbitration claim regardless of having signed the margin agreement.

What is the statute of limitations for a margin abuse claim?

Under FINRA Rule 12206, claims must be filed within six years of the events giving rise to the dispute. California investors may have additional state law claims with different limitations periods. Contact Bakhtiari & Harrison promptly — time limits are strictly enforced.
