Margin buying, also known as buying on margin, refers to the practice of purchasing an asset by using leverage and borrowing the balance from a bank or broker. This financial strategy allows investors to buy more securities than they could with their available cash, amplifying both potential gains and potential losses.
How Margin Buying Works
Leverage
Leverage is the use of various financial instruments or borrowed capital to increase the potential return of an investment. In the context of margin buying, leverage allows investors to control a larger position in a security than they could with their own funds.
Borrowing from Brokers
When engaging in margin buying, investors open a margin account with a brokerage firm. The process usually involves the following steps:
- Opening a Margin Account: Investors must qualify for a margin account by meeting the broker’s requirements and depositing an initial margin, typically a percentage of the total investment.
- Borrowing Funds: The broker lends the remaining amount needed to purchase the securities, using the investor’s account as collateral.
- Interest: The borrowed amount accrues interest, which the investor is responsible for paying in addition to repaying the principal.
Special Considerations
Margin Requirements
The Federal Reserve Board, FINRA, and individual brokerage firms set margin requirements. The initial margin requirement is the percentage of a purchase that must be covered with cash or fully paid securities. Maintenance margin is the minimum account balance an investor must maintain; if the account value falls below this level, a margin call occurs, requiring the investor to deposit more funds or sell securities.
Example of Margin Buying
Suppose an investor wants to purchase $10,000 worth of stock but only has $5,000. By using margin buying, the investor can borrow the additional $5,000 from the broker. If the stock price increases, the investor realizes gains on the entire $10,000 investment. However, if the stock price falls, the investor’s losses are also magnified.
Risks
Margin buying involves significant risk, including the potential for losses that exceed the initial investment. Market volatility can lead to margin calls, requiring the investor to quickly provide additional funds or liquidate positions.
Historical Context
Margin buying played a significant role in the stock market crash of 1929 and the ensuing Great Depression. During this period, excessive margin buying led to speculative bubbles and widespread financial ruin when market prices collapsed, causing severe economic repercussions.
Applicability
Margin buying is commonly used by experienced investors and traders who are comfortable with the associated risks and have a thorough understanding of the securities they are trading.
Comparisons to Other Investment Strategies
- Buying on Margin vs. Short Selling: While margin buying involves borrowing funds to purchase securities, short selling involves borrowing securities to sell them, anticipating a price decline.
- Margin Buying vs. Option Trading: Both strategies use leverage, but option trading involves contracts that give the right, but not the obligation, to buy or sell securities at a predetermined price.
