Introduction
Margin in trading refers to a deposit a trader must make with either a stockbroker or an exchange to guarantee that they will complete a transaction. Buying shares on margin involves borrowing money from a stockbroker to fund a fraction of the investment. To protect the broker, a buyer is required to deposit a margin, a fraction of the price sufficient to cover potential losses if the buyer fails to complete the transaction.
Historical Context
The concept of trading on margin dates back to the early 20th century when margin trading became widespread during the stock market boom in the United States. The most infamous event associated with margin trading is the Stock Market Crash of 1929, which was partly fueled by excessive margin buying. This led to the introduction of more stringent regulations to manage the risks associated with margin trading.
Types/Categories of Margin
- Initial Margin: The minimum amount required to enter into a position.
- Maintenance Margin: The minimum balance that must be maintained in a margin account.
- Margin Call: A demand by the broker to deposit more funds if the account balance falls below the maintenance margin.
- Variation Margin: Additional funds required by the broker if the market moves against the trader’s position.
Key Events
- 1929: Stock Market Crash in the USA partly due to excessive margin trading.
- 1934: Securities Exchange Act establishing margin requirements.
- 2008: Financial crisis highlighting the risks of leveraged trading.
Detailed Explanation
Margin trading involves the use of leverage, allowing traders to amplify their positions. This can lead to higher profits, but also greater losses. Here’s how it works:
Example Calculation
If you want to buy 100 shares of a company at $50 per share, the total cost would be $5,000. If the broker’s margin requirement is 50%, you would need to deposit $2,500, while the remaining $2,500 can be borrowed from the broker.
Mathematical Models
The margin required can be calculated using the formula:
