Understanding Leverage: The Double-Edged Sword

Leverage is a strategic tool that has captivated traders, offering a gateway to the lucrative potential within the trading world. Picture this: the ability to enhance your trade exposure by utilizing borrowed funds, elevating your market exposure far beyond the constraints of your available cash. 

In essence, leverage enables traders to navigate the markets with heightened potential. The underlying principle is simple yet powerful – a leveraged position can magnify returns when market conditions align with your outlook. However, caution prevails as the double-edged nature of leverage becomes apparent; in adverse market movements, losses have the potential to be accentuated. 

  1. How does leverage work? 

The concept of leverage is relatively simple. The process involves posting margin, which can be considered similar to a deposit, representing a fraction of the total value of your trade exposure. The remaining funds are then borrowed from the broker to provide you with a large exposure to the market while only needing a small initial outlay. Let’s look at an example. 

  • Trader A (No Margin):  
  • Buys 100 shares of Company A at $50 (Initial outlay = $5,000) 
  • Share price goes up 10% to $55 and trader sells (Selling value = $5,500) 
  • Total Profit = $500 (10% of invested funds) 
  • Trader B (Margin): 20% Margin Requirement 
  • With a $5,000 initial outlay, a trader can get exposure of $25,000 by borrowing the remaining $20,000 from the broker. 
  • Position worth $25,000 and share price appreciates by 10% 
  • Selling Value = $27,500 
  • Profit = $2,500 
  • Trader put down $5,000 and made $2,500 profit (50% return on invested funds)  

In this basic example of a leveraged trade, the benefits become evident. However, it should be noted that any movement in an adverse direction will have the same effect. In a leveraged trade, the trader’s losses will be amplified in the same way as the profits shown above.  

  1. Important Concepts 
  • Margin Requirements 

To trade with leverage, a trader may require a margin account. This is an account in which the broker would lend the trader funds to purchase more securities than would otherwise be possible with the available balance in the account. Margin requirements refer to the portion of marginable securities that the trader must pay with their own funds. Margin requirements can be broken down into initial margin and maintenance margin.  

  • Initial Margin 

The initial margin requirement is the percentage of equity that is required to open a position. In simple terms, this is the percentage of the total market value of the purchase that the trader must pay in cash. For example, an initial margin requirement of 50% would provide a trader with $20,000 in purchasing power if a deposit of $10,000 is made. The purchasing power multiplier can be used to determine the trader’s buying power based on the initial margin requirement. 

  • Purchasing Power Multiplier = (1/Initial Margin %) 

Therefore, an initial margin requirement of 50% will provide the trader with (1/0.5) = 2X buying power. Similarly, a 20% initial margin requirement provides the trader with (1/0.20) = 5X buying power. In this case, a deposit of $100,000 would have purchasing power worth $500,000, where the remaining $400,000 is borrowed from the broker.  

  • Maintenance Margin 

After the initial deposit has been made and a trade has been executed, the maintenance margin will come into play. This is the minimum amount of money a trader must hold in the margin account after making a purchase. If the account’s net asset value falls below this maintenance requirement, a margin call will occur. Let’s look at an example: 

A trader wants to buy 100 shares of a company at $20 each. With a 50% initial margin, the trader would need to deposit $1,000 and borrow the remaining $1,000 from the broker. The maintenance margin is 40%. If the stock price falls to $14, the amount of the trader’s invested equity has fallen from $1,000 to $700 (0.5 X 100 X 14). However, the maintenance requirement is $800 (0.4 X 2,000). Therefore, the investor’s account has fallen below the maintenance requirement, and the broker could send a margin call to the investor to either deposit more cash or sell some securities to make up for the difference between the maintenance margin requirement and the account’s value.  

  • Margin Call 

As previously mentioned, a margin call occurs when an investor or trader’s equity in the margin account falls below the maintenance margin requirements. When this occurs, the trader usually has a short grace period in which to restore the account value to meet the margin requirements. The margin call is a demand from the broker which requires the customer to either inject additional cash or sell part of the security in order to bring the account value back to the required minimum. If the trader fails to adhere to the margin call, the broker may sell part of the existing securities to restore the required margin level. The formula for the price at which a margin call will occur is as follows: 

  • Margin Call Price = Purchase Price X (1-Initial Margin)/(1-Maintenance Margin) 

For example: If a trader purchases a security for $1,000 with an initial margin requirement of 50% and a 25% maintenance margin, a margin call will occur at 1,000 X (1 – 0.5)/(1 – 0.25) = $666.67. 

Summary 

In essence, leverage in trading is a potent tool that allows traders to amplify their market exposure using borrowed funds. While it can magnify profits when the market moves favourably, caution is essential due to the potential for amplified losses in adverse market conditions. Key concepts to be aware of include margin requirements involving initial and maintenance margins, which determine the trader’s purchasing power and the risk of margin calls if the account falls below the maintenance margin level.
