Options Trading Pose Unique Investor Protection Risks


Broker-dealers like Merrill Lynch must ensure that options strategies employed by its registered representatives are suitable for their clients. Among other duties, broker-dealers must perform due diligence on the customer and collect information about the customer to support a determination that options trading is appropriate for the customer.


Options accounts are also subject to specific supervisory reviews by broker-dealers, including reviewing the compatibility of options transactions with investment objectives and with the types of transactions for which the account was approved. FINRA rules also apply when opening customer accounts, including among others, customer identification requirements under anti-money laundering rules.


According to FINRA, trading options can come with significant risks. These risks vary greatly based on whether you’re buying or selling options, including expiration risk, assignment risk, dividend risk and margin risk.
