What is short selling?
Short selling is the process of borrowing shares from a broker and selling them on the open market, with the expectation that their price will drop. The trader later buys back the shares at a lower price and returns them to the broker, profiting from the difference. This practice is widely used in margin trading facility (MTF), where traders take advantage of borrowed capital to amplify their returns.
What is shorting?
Shorting is when traders sell borrowed shares, expecting their prices to drop so they can buy them back at a lower price. It’s often used in volatile markets to hedge risks. For instance, when traders expect Nifty index share prices to decline due to economic uncertainty or market corrections, they may short them to capitalize on the falling prices and generate potential profits.

How short selling works
Short selling involves borrowing shares from a broker, selling them in the open market, and later buying them back at a lower price. If the price declines, the trader profits from the difference; however, if the price rises, the trader faces losses. To initiate a short sale, traders must have a margin account and meet the brokerage’s margin requirements. The borrowed shares are sold at the current market price, and if the stock declines as expected, the trader repurchases them at the lower price before returning them to the broker. This allows the trader to pocket the difference as profit. However, if the price increases, losses can be substantial since there is no cap on how high a stock can rise. Traders must be cautious and implement risk management strategies, such as stop-loss orders, to limit their potential downside. Short selling is widely used in intraday trading and futures markets, where traders capitalize on short-term price movements.
What are short selling metrics?
Traders engaging in short selling must be familiar with the following metrics:
- Short interest ratio – Measures the percentage of shares that have been sold short relative to total shares outstanding.
- Days to cover – Estimates how many days it would take for short sellers to buy back shares based on average daily trading volume.
- Short percentage of float – Indicates the proportion of a company's publicly traded shares that have been sold short.
- Cost of borrowing – Represents the fee traders must pay to borrow stocks for short selling.
- Margin requirements – Defines the collateral needed to execute short trades.
When is short selling profitable?
Short selling is profitable when a trader successfully predicts a stock’s decline. By selling high and buying low, traders can generate gains in bearish markets. Profitability depends on timing, accurate market analysis, and strategic execution. Traders often look at technical indicators, market sentiment, and news developments to anticipate price declines. However, timing the market correctly is challenging, and short sellers must be prepared to exit positions quickly if market conditions change. Many traders hedge their positions by using options or diversifying their portfolios with ETFs. Risk management is critical in short selling to prevent excessive losses.
Example of short selling for a profit
An investor believes that Company A’s stock, currently trading at ₹1,000, will drop in value. They borrow 100 shares and sell them for ₹1,00,000. A week later, the stock falls to ₹900, and the trader buys back 100 shares for ₹90,000, making a ₹10,000 profit. This example demonstrates how traders benefit when prices decline.
When does short selling result in loss?
Short selling results in losses when stock prices rise instead of falling. Unlike traditional investments where losses are limited to the amount invested, short selling carries the risk of unlimited losses since stock prices can theoretically rise indefinitely. This makes short selling a high-risk strategy that requires precise market timing. Traders can also face forced liquidation if margin requirements are not met, leading to additional financial strain. Many short sellers use stop-loss strategies or hedge their positions using futures to mitigate risks.
Example of short selling for a loss
A trader shorts 50 shares of a company at ₹500 per share, expecting the price to fall. However, the stock price rises to ₹600, forcing the trader to buy back the shares at ₹600 each, incurring a ₹5,000 loss. This highlights the unlimited loss potential of short selling.
Example of short selling as a hedge
A portfolio manager holds a significant position in a stock but fears a short-term decline. They short sell futures contracts on the stock to offset potential losses. If the stock falls, the gains from short selling compensate for the portfolio decline, minimizing overall risk.
Advantages of short selling
Short selling allows traders to profit in declining markets, providing an opportunity to generate returns even when stock prices fall. It enhances market liquidity, as more shares are traded due to short positions. Short selling also acts as a hedging tool for investors who want to protect their portfolios from market downturns. Additionally, it enables traders to take advantage of market inefficiencies and mispriced stocks. For traders using margin trading facility (MTF), short selling offers an opportunity to leverage positions and amplify returns. However, traders must be cautious as leverage increases the risk of losses.
Disadvantages of short selling
Despite its advantages, short selling carries significant risks. The potential for unlimited losses is a major drawback, as stock prices can rise indefinitely. Traders must maintain sufficient margin balances, and failing to meet margin requirements can lead to forced liquidation. Short squeezes, where a stock's price rapidly increases due to heavy buying pressure, can result in significant losses. Additionally, borrowing costs and interest fees for short positions can eat into profits. Regulatory restrictions in some markets also limit short selling activities, making it a complex strategy that requires experience and risk management.
Risks of short selling
Short selling comes with several risks that traders must be aware of before engaging in this high-risk strategy:
- Market risk – If the stock price rises instead of falling, short sellers can face unlimited losses since stock prices have no upper limit.
- Short squeeze – A sudden price surge due to heavy buying pressure forces short sellers to cover their positions at higher prices, leading to substantial losses.
- Margin calls – Brokers require traders to maintain a minimum margin balance. If a stock price moves against the trader, they may need to deposit additional funds to maintain their position.
- Regulatory risk – Governments and regulatory bodies like SEBI impose restrictions on short selling during high volatility to prevent market manipulation.
- Liquidity risk – If a stock becomes hard to borrow or there is limited market activity, traders may struggle to close their positions.
- Borrowing costs – Short sellers must pay interest and stock borrowing fees, which can erode profits.
- Timing risk – Predicting price declines accurately is challenging, and mistimed short trades can lead to rapid losses.
- Counterparty risk – If a broker faces financial instability, the availability of borrowed stocks for short selling could be affected.
Naked short selling
Naked short selling occurs when traders sell shares without borrowing them beforehand. Unlike traditional short selling, where shares are first borrowed from a broker, naked short selling increases market risk by allowing traders to place orders without securing the assets.
In India, SEBI (Securities and Exchange Board of India) has banned naked short selling to prevent stock price manipulation and market instability. SEBI regulations require traders to confirm stock availability before shorting. The restriction ensures that stock prices are not artificially driven downward due to excessive selling pressure. While naked short selling is prohibited for retail investors, institutional investors must adhere to strict regulatory requirements.
Countries like the United States and the European Union have also implemented stringent regulations on naked short selling to maintain market transparency and prevent market abuse. The restrictions protect retail investors from sudden price distortions caused by unregulated selling activities.
