Buy to Cover


When it comes to investing, there are various strategies that investors can employ to maximize their returns. One such strategy is “buy to cover,” which is commonly used in short selling. In this article, we will explore the concept of buy to cover, how it works, and its potential benefits and risks. We will also provide real-life examples and case studies to illustrate its application in the financial markets.

Understanding Buy to Cover

Buy to cover is a term used in short selling, a trading strategy where an investor borrows shares of a stock from a broker and sells them in the hope that the stock price will decline. The investor then aims to buy back the shares at a lower price, return them to the broker, and profit from the difference.

When the investor decides to close their short position, they need to buy back the shares they initially borrowed. This process is known as “buy to cover.” By buying back the shares, the investor effectively returns the borrowed shares to the broker and closes their short position.

How Buy to Cover Works

Let's walk through an example to better understand how buy to cover works:

1. Investor A believes that Company XYZ's stock price will decline in the near future. They borrow 100 shares of Company XYZ from their broker and sell them at the current market price of $50 per share, generating $5,000 in cash.

2. Over the next few weeks, Company XYZ's stock price indeed declines to $40 per share. Investor A decides to close their short position and buy to cover the borrowed shares.

3. To buy to cover, Investor A purchases 100 shares of Company XYZ at the current market price of $40 per share, spending $4,000.

4. Investor A returns the 100 shares to their broker, effectively closing their short position.

5. By buying to cover at a lower price than they initially sold the shares for, Investor A realizes a profit of $1,000 ($5,000 – $4,000).

Benefits of Buy to Cover

Buy to cover offers several potential benefits for investors:

  • Profit from declining stock prices: Buy to cover allows investors to profit from their belief that a stock's price will decline. By selling borrowed shares at a higher price and buying them back at a lower price, investors can generate a profit.
  • Flexibility: Buy to cover provides investors with the flexibility to close their short positions at any time. This allows them to take advantage of market movements and manage their risk effectively.
  • Hedging: Buy to cover can be used as a hedging strategy to protect against potential losses in a long position. By short selling a stock and buying to cover when the price declines, investors can offset losses in their long position.

Risks of Buy to Cover

While buy to cover can be a profitable strategy, it also carries certain risks:

  • Unlimited potential losses: Unlike buying a stock, short selling has unlimited downside potential. If the stock price rises instead of declining, the investor's losses can be significant.
  • Margin requirements: Short selling typically requires investors to maintain a margin account with their broker. This means they need to have sufficient funds or collateral to cover any potential losses.
  • Market volatility: Buy to cover can be challenging in highly volatile markets. Sharp price movements can make it difficult to execute trades at desired prices, potentially impacting the profitability of the strategy.

Real-Life Examples

Let's look at two real-life examples to further illustrate the application of buy to cover:

Example 1:

Investor B believes that Company ABC's stock price is overvalued and will decline. They borrow 500 shares of Company ABC from their broker and sell them at the current market price of $100 per share, generating $50,000 in cash. Over the next month, the stock price drops to $80 per share. Investor B decides to buy to cover and purchases 500 shares at $80 per share, spending $40,000. By returning the shares to their broker, Investor B realizes a profit of $10,000 ($50,000 – $40,000).

Example 2:

Investor C holds a long position in Company XYZ's stock. However, they are concerned about potential market volatility and want to protect against potential losses. Investor C decides to short sell 200 shares of Company XYZ and buy to cover if the stock price declines. If the stock price does indeed decline, the profits from the short position can offset any losses in their long position.


Buy to cover is a strategy used in short selling, where investors borrow shares of a stock, sell them, and then buy them back at a lower price to close their short position. This strategy allows investors to profit from declining stock prices, provides flexibility in managing positions, and can be used as a hedging tool. However, it also carries risks such as unlimited potential losses, margin requirements, and challenges in volatile markets.

By understanding the concept of buy to cover and considering its potential benefits and risks, investors can make informed decisions and incorporate this strategy into their investment approach when appropriate.
