Definition of Option Margin
Option Margin refers to the cash or securities that an investor must deposit as collateral in their trading account before writing or selling options. This requirement is essential for mitigating the risks associated with options trading, and the amount can vary depending on the specific type of option involved. Regulation T set by the Federal Reserve dictates the minimum margin requirements for various securities, including options, but brokerage firms often have their own guidelines as well.
| Option Margin | Stock Margin |
|---|---|
| A collateral requirement specific to options writing. | A collateral requirement for buying and selling stocks on margin. |
| Can vary significantly based on the type of option being traded. | Varies based on the value of the underlying stock and the brokerage requirements. |
| Helps mitigate potential losses when an option is exercised. | Helps cover the risk of loss in trading stocks. |
| Typically lower than stock margin due to the nature of options. | Typically higher because of greater volatility in stock prices. |
Example of Option Margin
When writing a covered call option on 100 shares of XYZ Company, the broker may require a margin of $1,000 as collateral. If the option is exercised, this serves as protection for the broker against potential losses. On the other hand, if one were buying shares of XYZ on margin, the required collateral might be much higher given stock price fluctuations.
