Short selling is a trading tactic where you borrow shares, sell them right away, and hope the price drops. The plan is to buy the shares back later at a lower price, return them to the lender, and keep the difference.
How short selling works
- Open a margin account: You need a margin account to short a stock. It lets you borrow money and securities from your broker, using your holdings as collateral.
- Borrow and sell shares: Choose a stock you think is overpriced and likely to fall. Your broker finds shares to borrow from clients or institutions and sells them at the current market price. The sale proceeds show up in your account, but you usually cannot withdraw them until you close the short.
- Monitor the position: Watch the stock closely. You pay interest while the shares are borrowed, and if the company pays a dividend, you must cover that payment to the lender.
- Close the position: If the price drops, you buy the same number of shares at the lower price to cover your short.
- Return shares and calculate profit: The purchased shares go back to your broker. Your profit is the sale price minus the buyback price, after commissions, interest, and any fees.
Risks of short selling
Short selling carries significant risk and suits experienced traders.
- Unlimited loss potential: A stock can rise without limit, so your losses can keep growing. Your best possible gain is capped at the sale price if the stock goes to zero.
- Margin calls: A sharp price rise can cut your account equity below the maintenance margin. Your broker may require more funds, or close your position at a loss.
- Short squeezes: A fast price jump can push many short sellers to cover at once. The wave of buying lifts the price further, which can magnify losses.
- Borrowing costs and dividends: You owe margin interest and may face hard-to-borrow fees. You also pay any dividends issued while you are short.
- Market bias: Over long periods, the stock market tends to rise, which works against short trades over time.
