Margin is a loan from your broker to help pay for the securities you buy. Normally, you can finance up to 50 percent of your purchases with margin. For example, if you have $10,000 in cash in your margin account, you can buy $20,000 worth of stock. The shares you buy are collateral for the loan of $10,000.
