How does my margin account work?

Generally, a client pledges the securities in their account as collateral for a loan that they may then use to purchase additional securities. The Federal Reserve Board (FRB) sets margin requirements for various marginable securities. For instance, the current margin requirement for initial purchase of eligible securities is 50% of the purchase amount. This is commonly referred to as the Regulation T (Reg T) requirement. Under Reg T, you must have at least 50% of the value of the trade in your account in either cash or fully paid marginable securities by settlement date of the trade. Although, The Federal Reserve determines which stocks can be used as collateral for margin loans, TD Ameritrade is not obligated to extend margin on all approved stocks.

As an example, a client with $10,000 of cash in a margin account would be able to purchase up to $20,000 worth of marginable securities, this is known as a client’s Stock Buying Power.

Margin trading increases risk of loss and includes the possibility of a forced sale if account equity drops below required levels. Margin is not available in all account types. Margin trading privileges subject to TD Ameritrade review and approval. Carefully review the Margin Handbook and Margin Disclosure Document for more details.
