What Does It Mean to Cover a Short?

Financial markets involve numerous strategies and terminologies. Various trading approaches exist, including those designed to potentially generate gains even when asset prices decline. This article aims to clarify one such specific action within these markets.

Short Selling Fundamentals

Short selling involves an investor borrowing shares of a company and immediately selling them on the open market. The primary objective is to purchase these same shares back at a lower price in the future. The difference between the initial selling price and the subsequent lower repurchase price, minus any associated costs, represents the potential gain for the short seller. This strategy is based on the expectation that the stock’s market value will decrease.

To engage in short selling, an investor needs a margin account with a brokerage firm. The shares are borrowed from another investor, and the proceeds from the sale are held in the account as collateral. The short seller is obligated to return the exact number of shares borrowed to the lender. Brokers require short sellers to maintain a certain amount of equity in their margin account to cover potential losses.

Short sellers incur various costs, including borrowing fees for the shares. If the company pays dividends while the shares are shorted, the short seller is responsible for covering these dividend payments to the lender. Unlike buying a stock, where potential losses are limited to the initial investment, the potential loss in a short sale is theoretically unlimited if the stock price rises indefinitely.

The Act of Covering a Short Position

“Covering a short” refers to the action taken by a short seller to close their borrowed stock position. This involves buying back the exact number of shares initially sold short. Once repurchased, they are returned to the lender, fulfilling the short seller’s obligation and ending the position. This action is distinct from simply buying shares for a long position.

A short seller might cover their position for several reasons. If the stock’s price has declined as anticipated, they would buy back the shares at a lower price to realize a profit. Conversely, if the stock’s price has risen, they might cover to limit further losses. Another common reason to cover is to meet a margin call, which occurs when the value of the shorted stock increases, causing the equity in the margin account to fall below the required maintenance level.

When covering a short, an investor places a “buy to cover” order with their brokerage. For example, if 100 shares were shorted at $50 each, the investor would buy 100 shares. If they buy them back at $40, a $10 per share profit is realized before fees. If they buy them back at $60, a $10 per share loss is incurred. Profits from short sales are subject to capital gains taxes.

Understanding Short Squeezes

A short squeeze occurs when a stock’s price rapidly increases, forcing short sellers to buy back shares to limit their losses or satisfy margin calls. This collective buying pressure further drives up the stock price. It is characterized by intense buying activity, distinct from an individual’s decision to cover a short position.

This event happens when a stock has a high level of “short interest,” meaning a large number of its shares have been sold short. A catalyst, such as unexpected positive news, a sudden surge in demand, or a significant institutional purchase, can trigger an initial price increase. As the price rises, short sellers face mounting unrealized losses and may receive margin calls from their brokers.

To avoid further losses or meet margin requirements, short sellers are compelled to buy shares back, regardless of the price. This forced buying creates additional demand for the stock, pushing its price even higher. This upward momentum puts pressure on other short sellers, leading to a rapid increase in the stock’s value. A short squeeze can lead to significant price volatility and financial consequences for those holding short positions.
