What is margin trading?

Margin trading allows investors to borrow funds from a brokerage to purchase more securities than their cash balance would otherwise permit. By using existing assets as collateral, traders can increase their buying power. For example, a trader with 5,000 dollars in their account might use margin to buy 10,000 dollars worth of stock. The brokerage charges interest on the borrowed amount, which is typically calculated daily based on the margin interest rate. This strategy amplifies both potential gains and potential losses. If a stock position increases in value, the trader earns returns on the full position size. Conversely, if the value drops, the losses are calculated against the total position, which can quickly exceed the initial cash investment. If the account value falls below a specific threshold, known as the maintenance margin, the broker will issue a margin call. This requires the trader to deposit additional cash or sell assets immediately to cover the shortfall. Trading on margin involves significant risk, as it is possible to lose more money than the initial deposit. Beginners should thoroughly understand the interest costs and liquidation risks before utilizing margin in their accounts.
