What is margin investing?

When you invest on margin, you borrow either cash or securities from a broker, like Vanguard Brokerage, to complete a transaction, instead of paying for the transaction in full.

Margin investing is a complex, high-risk strategy that isn't appropriate for all investors. But used appropriately, margin investing can potentially increase your investment returns and provide you with credit flexibility.

Understand the risks & benefits of margin investing

If you understand the risks of margin investing, you may still decide it's the right strategy for you.

How your margin account works

Vanguard Brokerage only allows margin investing in nonretirement Vanguard Brokerage Accounts with our prior approval.

Your margin account information will be displayed on the Margin balance detail screen when you log in to your account.

These details include your margin account buying power, a summary of margin information such as margin cash available, and margin call information.

Once you're approved for margin trading, you must buy or sell eligible securities in your margin account.

Short sales

Short sales are a feature of margin accounts. When you sell short, you sell stock that you've borrowed from a broker, hoping its price will drop in the near future so you can buy the shares back and turn a profit.

How you make a profit …

You borrow 100 shares of stock from your broker and sell them for $40 a share, or $4,000.

The stock drops to $30 and you buy 100 shares at a cost of $3,000.

You return the shares to your broker and pocket a profit of $1,000.

… Or suffer a loss

The risk you take with a short sale is that the stock will rise. If that's the case, there's no limit to how much money you can lose.

Using the same example, if the stock you sell at $40 rises to $60, you'll have to pay $6,000 to return the 100 shares to your broker. That's a $2,000 loss.

Margin calls

To comply with regulations on margin investing, you must maintain a certain amount of equity in your margin account at all times, depending on the securities held in the account.

If you don't meet minimum requirements, you'll get a margin call—a notice you have to increase the equity in your account to cover the call.

The profit you get from investing money. Over time, this profit is based mainly on the amount of risk associated with the investment. So, for example, less-risky investments like CDs (certificates of deposit) or savings accounts generally earn a low rate of return, and higher-risk investments like stocks generally earn a higher rate of return.

Margin account buying power

The amount of money available in your margin account to purchase marginable securities. Buying power consists of your money available to trade, plus the amount that can be borrowed against securities held in your margin account. For example, if you have $50,000 in your money market settlement fund, your buying power is actually $100,000 because you're required to deposit just 50% when buying or selling short most marginable securities.
