What is short selling?

Key Points

• Short selling (shorting) is the practice of selling an asset with the intention of buying it back later at a lower price.

• Shorting generally involves borrowing funds, which means it requires an initial margin (collateral), a maintenance margin, and interest payments.

• Traders and investors widely use short selling to speculate on market movements or as a hedging strategy to offset potential losses in other assets.

• Shorting carries disadvantages, including the risk of unlimited losses if prices continue to rise, forced liquidations, the potential for a short squeeze, and added expenses such as borrowing fees.

Introduction

There are countless ways to profit in financial markets. Some traders focus on technical analysis, while others invest in companies and projects based on fundamental analysis.

Typically, traders aim to buy assets at a low price and sell them later for a profit when prices go up. But what happens when they face an extended bear market where prices keep falling?

Shorting the market enables traders to profit from declining prices. Opening a short position can also be an effective way to manage risk and hedge existing holdings against price fluctuations.

Short selling dates back to the Dutch stock market in the 17th century but gained greater prominence during events like the 2008 financial crisis and the 2021 GameStop short squeeze, when retail investors drove up prices to pressure short sellers.

What Is Short Selling?

Short selling (shorting) means selling an asset in anticipation of buying it back later at a lower price. A trader opening a short position expects the asset’s price to fall—they are bearish on that asset.

Instead of simply holding and waiting, some traders use short selling to profit from a decline in an asset’s price. For this reason, short selling can also help preserve capital during a market downturn.

Shorting is common across nearly all financial markets, including equities, commodities, forex, and cryptocurrencies. Both retail investors and professional trading firms, such as hedge funds, frequently employ short selling strategies.

The opposite of a short position is a long position, where a trader buys an asset expecting to sell it later at a higher price.

Short selling serves two primary purposes:

• Speculation: betting on a price drop to generate profit.

• Hedging: offsetting potential losses in other investments, such as a long position in a related asset.

Although stocks are the most common securities for short selling, this strategy also applies to other assets like cryptocurrencies, bonds, or commodities.

How Short Selling Works

Suppose you are bearish on a financial asset. You post the required collateral, borrow a certain amount of the asset, and sell it immediately. You now hold an open short position. If the market moves in your favor and declines, you repurchase the same amount and return it to the lender (plus interest). Your profit is the difference between your original sale price and your repurchase price.

Examples

Short Selling Bitcoin

You borrow 1 BTC and sell it for $100,000. You now have a short position of 1 BTC and are paying interest on it. If Bitcoin’s market price drops to $95,000, you buy 1 BTC and return it to the lender (usually the exchange). Your profit in this case is $5,000 (less interest and fees). However, if the price rises to $105,000, buying back 1 BTC results in a $5,000 loss plus commissions and interest.

Short Selling Stocks

Suppose an investor believes that shares of XYZ Corp, currently trading at $50 per share, will decline. They borrow 100 shares and sell them for $5,000. If the price drops to $40, they repurchase the shares for $4,000, return them, and earn a $1,000 profit (minus fees). However, if the price rises to $60, buying them back costs $6,000, resulting in a $1,000 loss, plus extra costs like borrowing fees or interest.

Types of Short Selling

There are two main types of short selling:

• Covered short selling: involves borrowing and selling actual shares—this is the standard approach.

• Naked short selling: involves selling shares without first borrowing them, which is much riskier and often restricted or illegal due to the risk of market manipulation.

Short Selling Requirements

Since short selling involves borrowing funds, traders typically must provide collateral via a margin or futures account. If you short via a margin trading broker or exchange, consider the following:

• Initial margin: In traditional markets, the initial margin is usually 50% of the value of the shorted shares. In crypto markets, requirements depend on the platform and leverage. For example, with 5x leverage, a $1,000 position requires $200 in collateral.

• Maintenance margin: The maintenance margin ensures your account has enough funds to cover potential losses. It’s often calculated based on your margin level (total assets ÷ total liabilities).

• Liquidation risk: If your margin level drops too low, your broker or exchange may issue a margin call, requiring you to deposit more funds or liquidate positions to cover borrowed funds, which could lead to significant losses.

Benefits of Short Selling

Short selling offers several advantages to investors and traders:

• Profit in declining markets: traders can capitalize on falling prices, unlike traditional long-only strategies.

• Hedging: helps protect portfolios by offsetting losses in long positions, especially in volatile markets.

• Price discovery: Some argue that short sellers help correct overpriced stocks by revealing negative information, boosting market efficiency.

• Liquidity: Increases trading activity and makes it easier for buyers and sellers to transact.

Risks of Short Selling

Entering a short position comes with several risks. Most notably, potential losses on a short position are theoretically unlimited.

Many professional traders have gone bankrupt over the years while shorting stocks. If a stock price rises on unexpected news, the price spike can quickly “trap” short sellers (a short squeeze).

Other potential downsides of short selling include:

• Borrowing costs: fees and interest vary, especially for hard-to-borrow stocks in high demand.

• Dividend payments: In stock markets, short sellers must pay any dividends issued during the short period, increasing costs.

• Regulatory risks: Temporary bans or restrictions during market crises can force short sellers to cover at unfavorable prices.

Market and Ethical Considerations

Short selling is a contentious practice. Critics claim it can worsen market downturns or unfairly target companies, harming employees and shareholders. For example, aggressive short selling during the 2008 financial crisis led to temporary bans in several countries. Supporters, however, argue that short selling increases transparency by exposing overvalued or fraudulent firms.

Regulators balance these concerns with rules like the uptick rule (restricting short sales during sharp declines) and disclosure requirements for large short positions. In the US, SEC Regulation SHO governs short sales to prevent manipulation, including naked shorting.

Conclusions

In summary, shorting is a widely used strategy that enables traders to profit from falling prices. Whether for speculation or hedging, short selling remains a critical feature of both traditional and crypto markets. However, it’s vital to understand the risks and downsides of shorting, including unlimited losses, short squeezes, and transaction costs.

FAQ

What’s the difference between going long and short selling?

Long position: you buy assets expecting the price to rise. Short position: you sell borrowed assets, expecting to buy them back cheaper and profit from the price drop.

Who can short sell and where is it allowed?

Qualified investors can short sell in regulated markets, including futures, forex, and cryptocurrencies. This requires meeting regulatory criteria and using authorized platforms.

What’s a real-world example of short selling?

For example, if Bitcoin trades at $40,000, you borrow 1 BTC and sell it. If the price drops to $35,000, you buy back 1 BTC and return it, earning a $5,000 profit.

What are the legal and regulatory restrictions on short selling?

Short selling is legal in many countries but subject to various regulations depending on the jurisdiction. Key restrictions include limits on short volumes, mandatory reporting to authorities, bans during extreme volatility, and rules against manipulation. Each country sets its own rules.
