In stock trading, margin refers to Regulation T (“Reg T”) margin, which allows investors to borrow a portion (generally between 30% and 50%) of the purchase price, using the stock as collateral. If the stock falls below a certain level, the investor will need to either deposit more money or close out positions in the account.
