What is Short Covering - Meaning, Examples and How it Works

Published on December 01, 2022 | 12 min read

Key Takeaways:

Short covering is a scenario in which a trader buys back shares or a derivative position to close an existing short position.
In short covering, the stock price usually rises as existing short positions are closed.
A high volume of short covering can contribute to a short squeeze when short sellers rush to close their positions as prices rise.
Short covering is not fresh buying. It is the closing of an existing short position through a buy transaction.

The term ‘short covering’ means closing a short position or trade. Before learning about short covering, it is crucial to understand short selling. In short selling, traders sell a stock at a higher price with the expectation of buying it back at a lower price. If the price declines, the trader may earn a profit from the price difference.

However, if market sentiment turns bullish due to positive news, the stock price may rise. When the stock price rises, short sellers may seek to close their short positions, potentially at a loss. The buy orders placed to close existing short positions can contribute to upward price pressure.

This comprehensive guide explains short covering with examples, how it works, when it happens, how to identify it and its impact on stock prices.

Short covering refers to the process of buying back a security or closing a derivative position that was previously shorted. Traders short-sell when they believe the stock price will fall, so they can buy it back later at a lower price and potentially earn a profit.

But if the shorted stock price rises, they have to repurchase the security or close the derivative position at a higher price, incurring a loss. In both cases, closing the existing short position is called short covering.

Example:

A trader sells a Nifty futures contract at 24,200 and expects that prices will decline to 24,000 in the coming days. This scenario represents a short position in Nifty futures.

Later, instead of declining, the Nifty price rises to 24,350; the short seller incurs a loss because the Nifty is moving in the opposite direction.

In this scenario, the trader may buy back the Nifty futures contract to close the short position; this is called short covering.

A similar situation can occur in both futures and options. When short covering occurs in derivatives, open interest can decline as existing positions are closed.

However, a decline in open interest alone does not establish that short covering is taking place, as open interest can change for multiple reasons. NSE defines open interest as the total number of derivative contracts that have not yet been offset, closed or otherwise settled.

How Does Short Covering Work?

Short covering begins when a trader holds a short position in stocks, futures or options. The trader may have entered that position because technical indicators, valuations, news or market sentiment suggested falling prices.

When the market, stock, or derivative positions move against the short position, the trader begins to incur losses. To limit the losses, the trader may decide to close the trade by buying back the security or derivative contract.

In the securities lending and borrowing (SLB) mechanism, short sellers may borrow securities through an approved intermediary, provided they return equivalent securities within the specified period. If the borrower fails to do so, applicable default and collateral mechanisms may be invoked.

If a share or derivative contract experiences heavy short-covering, it may contribute to a short squeeze. In this scenario, rising prices can put pressure on short sellers to close their positions, fueling further upward momentum.

When Does Short Covering Happen?

Short covering can occur in several market conditions, which are as follows:

Price reversal:

Short covering can occur when a falling stock or index suddenly moves higher as sellers begin to exit bearish positions.

Positive news in the stock:

Corporate announcements, positive earnings reports, policy decisions, and economic developments can trigger a bullish move in the stock and, in some cases, prompt some short sellers to close their positions.

Technical Level:

When there is a breakout at any important resistance level, the stock price may rise sharply. It can prompt short sellers to close their positions, further adding to the upward price pressure.

Demand Zone:

When a stock repeatedly holds a major support zone, short sellers may lose confidence and choose to close their positions, potentially triggering short covering.

Expiry Day:

In futures and options, expiry is the date on which a specific contract expires. Short sellers may close or roll over positions before settlement, due to increased volatility. Their move also depends on their positions and trading strategies.

Improved sentiment:

Any positive news in global markets, increased institutional buying activity, or policy developments might improve investor confidence.

How to identify short covering in the market?

Short covering occurs when traders close the existing short position, which can spark buying pressure and drive stock prices higher. Identifying short covering can help you understand whether a price jump is driven by fresh buying, a temporary adjustment, or by the closing of short positions.

Here are some ways which can help traders identify short covering in the market:

Increase in price, decrease in open interest:

When short covering happens, the stock price increases but open interest declines. It shows that the existing short positions are being closed rather than genuine buying.

Higher Trading Volume:

During short covering, trading volume may increase as many participants close short positions due to rising prices, fear of loss, or expiry settlement.

Option Chain Data:

At the time of short covering, open interest at important strike prices may change substantially. Usually, the call open interest shows a sharp decline, indicating that existing bearish positions are being closed, but this alone does not confirm short covering.

Market-wide confirmation:

When several stocks and major indices show a similar pattern, the probability of broad short covering increases.

Resistance breakout:

A strong move above the resistance level can force short sellers to cover their positions, triggering upward price pressure.

Impact of Short Covering on Stock Prices

Short covering in the share market can cause a sharp rise in share prices as traders rush to close their short positions. This increased demand can push the stock price upward without any strong fundamental support. Such a move is usually temporary because it is driven primarily by the closing of existing short positions rather than by fresh buying.

In short covering, the volatility in stock prices increases due to uncertainty about how much prices can rally in a short time.

Sometimes, short covering can also signal the start of a new bullish trend. This often happens when stock prices have consolidated within a narrow range for an extended period. Any breakout attempt above the range can hit the stop-losses of short-sellers, prompting them to close their positions. It may also attract new buyers, increasing upward price momentum and validating the breakout.

Heavy short covering in options on benchmark indices such as the Nifty and Sensex can influence overall market movements and create noticeable intraday volatility.

What is a Short Squeeze?

A short squeeze occurs when a security's price increases sharply, forcing a large number of short sellers to close their positions, which, in turn, can further increase buying pressure. Generally, squeezes are more powerful than short covering, though a short squeeze can involve substantial short-covering activity. The two terms are not interchangeable.

In a short squeeze, share prices can jump 10% to 20% intraday. Its extent can vary depending on factors such as short positioning, liquidity and the magnitude of the price movement. However, F&O stocks usually have circuit limits that prevent them from moving beyond a specific level intraday. What is Short Interest in Short Covering?

Short interest refers to the total number of shares that investors have sold but not yet covered. High short interest indicates that many investors and traders believe the stock price may fall and so hold short positions in the stock.

Monitoring short interest is important because it helps understand the extent of short positioning in a stock. But short interest alone cannot determine whether a subsequent price move is due to short covering or fresh buying.

What is Long Unwinding?

Long unwinding is a scenario in which existing long, or bullish, positions are closed. The term long unwinding is mostly used in futures and options.

Long unwinding occurs when a trader closes an existing long position, expecting prices to decline. As a result, existing long positions are squared off to protect profits.

In long unwinding, put sellers with bullish positions tend to close their positions by selling the security or derivative contract. This can result in a decrease in open interest. During long unwinding, the share price typically declines, while during short covering, it tends to rally.

Difference Between Short Covering and Long Unwinding

Here are the key differences between short covering and long unwinding:

Basis	Short Covering	Long Unwinding
Meaning	Short covering occurs when traders buy back previously sold positions to close bearish trades.	Long unwinding occurs when traders sell existing long positions to close bullish trades.
Original Position	The trader initially holds a short position.	The trader initially holds a long position.
Expected Market View	The original expectation was generally that prices would decline.	The original expectation was generally that prices would increase.
Closing Transaction	Traders buy back the security or derivative contract.	Traders sell the security or derivative contract.
Price Impact	Short covering can create upward pressure because short sellers must buy back their positions.	Long unwinding can create downward pressure because existing buyers need to sell.
Open Interest	Rising prices with declining open interest can indicate short covering in derivatives.	Falling prices with declining open interest can indicate long unwinding in derivatives.
Market Sentiment	It can indicate that bearish traders are becoming less confident.	It can indicate that bullish traders are reducing their conviction.
Typical Outcome	Prices may recover or rise rapidly if covering is widespread.	Prices may decline as multiple long positions are closed.
Example	A trader sells Nifty futures and later buys them back after Nifty rises.	A trader buys Nifty futures and later sells them after Nifty declines.

Is Short Covering Bullish or Bearish?

Short covering is sometimes considered a bullish price signal because the stock price tends to rise as short positions are closed, which involves buying. However, it is important to understand that, to sustain the price at a higher level and rally further, fresh buying is needed.

Short covering does not guarantee fresh buying in the stock. The price movement may be temporary. However, from a technical perspective, it forms a bullish candle when the price closes higher.

Short covering can be one reason for a change in the short-term trend. If the stock price sustains gains from the short-covering move, fresh buying could emerge, pushing the price to new highs.

Risk Associated With Short Covering

Here are some common risks associated with short covering in the stock market.

False Signal:

Rising stock prices while a decline in open interest can suggest short covering, but other market factors can produce similar price patterns.

Sudden Reversal:

A short-covering rally can disappear quickly when the temporary demand generated by closing short positions ends. The price can reverse lower after short sellers close their positions on stop-loss orders.

Short Squeeze:

The risk of a short squeeze increases when positive news hits the market suddenly. At the time of a squeeze, short sellers may face the risk of exiting their positions at higher prices.

Liquidity Risk:

Some specific OTM contracts may have limited liquidity, making it difficult for market participants to exit during volatile market conditions.

Event Risks:

Unexpected corporate announcements can accelerate short-covering and create price gaps because planned stop-loss orders may not be executed at the expected price in volatile market conditions.

Misinterpretation Risk:

Traders may mistake short covering for fresh buying. A short-covering move is usually temporary, and the stock may not rise above a certain level or sustain its gains without fresh buying.

Option Decay:

Option buyers may face the risk of time decay in option premiums. This happens when the price moves upward due to short covering, and it also depends on the option and market conditions.

Short covering is a market scenario where short sellers buy back their existing bearish positions. It results in an increase in buying orders, which can push the stock price higher without any fundamental support, only by increasing buying pressure.

When many short sellers cover their positions simultaneously, the move can become a short squeeze, amplifying a price jump.

Short covering can be identified by analysing open interest alongside stock prices. When open interest decreases and the stock price rises, it can signal a short-covering move.

Understanding the difference between short covering and fresh buying is important. A rally driven by fresh buying may have different implications from one driven primarily by the closing of existing short positions.
