Key Takeaways
- Borrow funds to amplify trading positions.
- Requires maintaining minimum equity to avoid margin calls.
- Leverage increases both potential gains and losses.
What is Margin?
Margin is the practice of borrowing funds from a broker to increase your trading position beyond the cash you have available, using your account assets as collateral. This leverage allows you to control larger investments, amplifying both potential gains and losses.
Understanding margin is essential for traders who want to expand their market exposure, as it involves specific requirements like loan-to-value ratios and risk management measures.
Key Characteristics
Margin trading has distinct features that affect your investment strategy and risk profile.
- Leverage: Enables control of a larger position with less capital, increasing both profit potential and risk.
- Initial Margin: The upfront collateral you must deposit, often regulated at 50% by U.S. rules, but can vary by broker.
- Maintenance Margin: Minimum equity you must maintain to avoid a backstop liquidation by the broker.
- Margin Call: A broker’s demand for additional funds if your equity falls below the maintenance margin threshold.
- Interest Costs: Borrowed funds accrue interest, impacting overall profitability.
How It Works
When you trade on margin, you deposit a portion of the trade value, known as the initial margin, while the broker loans the remainder. This loan is secured by your account assets, and you must maintain a minimum equity level to avoid a margin call.
For example, with an initial margin of 50%, buying $10,000 worth of stock requires a $5,000 deposit, while the broker finances the rest. If the stock value declines and your equity falls below the maintenance margin, the broker may require additional funds or liquidate your position. This mechanism is similar to the rules governing haircuts, which determine collateral value adjustments.
Examples and Use Cases

Important Considerations
Margin amplifies both gains and losses, so it requires disciplined risk management and thorough understanding of your broker’s terms. Interest expenses and margin calls can quickly erode profits or increase losses, especially in volatile markets.
Before trading on margin, ensure your account meets minimum requirements, and consider how margin fits your overall investment strategy. Reviewing broker policies and using risk controls like stop-loss orders can help mitigate margin risks effectively.
Final Words
Margin trading can amplify your gains but also magnifies losses and risks like margin calls. Carefully assess your risk tolerance and run the numbers before using leverage to ensure it aligns with your investment strategy.
Frequently Asked Questions
Margin trading involves borrowing funds from a broker to increase your trading position beyond your available cash. You deposit an initial margin as collateral, and the broker lends you the rest, allowing you to control larger positions with less capital.
Initial margin is the upfront deposit, usually around 50% of the position's value, required to open a margin trade. Maintenance margin is the minimum equity you must maintain, typically 25-30%, to avoid a margin call from your broker.
If your equity drops below the maintenance margin, your broker will issue a margin call, requiring you to deposit more funds or close positions. Failure to meet this call can lead to forced liquidation of your assets at potentially unfavorable prices.
Margin trading uses leverage, so gains and losses are magnified relative to your initial deposit. For example, a 20% price increase could yield a 40% profit on your deposit, but a 20% drop could also mean a 40% loss, plus interest charges.
Yes, you pay interest on the borrowed funds, which typically ranges from 6-12% depending on the broker and loan size. These costs can reduce your overall profits, especially if you hold positions for a long time without gains.
Margin trading carries significant risks including magnified losses, margin calls, forced liquidation, interest expenses, and potential losses exceeding your initial investment if positions move against you.
