Margin refers to the borrowed money from a broker that allows investors to trade larger positions than their account balance would normally allow. Essentially, margin gives traders the ability to leverage their investments by borrowing funds to make additional trades, increasing both potential profits and risks.

Key Aspects of Margin:

  • Margin Account: A type of brokerage account where the broker lends the trader money to buy securities.
  • Initial Margin: The amount of money a trader must deposit to open a leveraged position. It is typically a percentage of the total investment.
  • Maintenance Margin: The minimum amount of equity a trader must maintain in their margin account to keep the position open. If the balance falls below this threshold, a margin call is issued.

Margin Requirements:

Margin requirements are set by brokers and regulatory authorities to limit the amount of leverage traders can use, protecting both the investor and the broker from excessive risk.

  • Regulatory Requirements: In the U.S., FINRA requires a minimum of 25% equity in a margin account for most stocks.
  • Broker Requirements: Brokers may set higher margin requirements depending on the risk profile of the asset or the account.

Risk of Margin Trading:

  • Margin Call: If the value of the investment falls too much, the broker can issue a margin call, demanding the investor deposit more funds to meet the required margin.
  • Potential Losses: If the trade goes against the investor, they may end up owing more than the initial investment, leading to significant financial losses.

Important Note: While margin can amplify returns, it also increases risk, and investors should fully understand the terms and risks before using margin for trading. See also: Day Trading and Cash Account
