A margin account is a brokerage account in which the broker lends the customer cash to purchase stocks or other investments. The loan in the account is collateralized by the securities and cash the client deposits. As such, margin accounts are commonly used to purchase more securities than the customer could normally afford.
In order to open a margin account, the investor usually has to deposit a certain amount, which is known as the initial margin. This minimum value is usually set by the brokerage firm, but it can vary depending on the type of security it’s buying and the risk associated with it. Once the initial margin is met, the investor can borrow more money (known as the maintenance margin) up to a certain percentage of the value of the securities he holds.
The investor is responsible for paying back this loan at the prevailing market rate, often with interest. The interest rate can range from a few percentage points to over 10%. Additionally, when the value of the securities held by the investor decreases, the investor would be required to deposit additional funds (called a margin call) in order to meet the maintenance margin requirement.
Though margin accounts can be a great tool for experienced investors looking to increase their purchasing power, it’s also important to understand the risks associated with it. Leveraging investments can increase profits and losses, so it’s important to understand the margin requirements and to monitor the market closely so you can exit your positions quickly if needed.
In summary, margin accounts are financial accounts that allow investors to borrow money in order to purchase securities. While these can be an effective tool for experienced investors, potential margin account holders should take the time to understand the associated risks.
