Short Selling

A strategy of borrowing shares and selling them with the intention of buying them back later at a lower price, profiting from a decline in the stock's value.

To short a stock, an investor borrows shares from a broker (who lends them from another client's account), sells them at the current market price, and later buys them back to return to the lender. The profit or loss is the difference between the sale price and the repurchase price. If you short 100 shares at $50 and buy them back at $35, your profit is $1,500. If the stock rises to $65, your loss is $1,500.

Short selling has a critical asymmetry: gains are capped at 100% (the stock can only fall to zero) while losses are theoretically unlimited (a stock can rise without bound). This asymmetry, combined with borrowing costs and the fact that shorts must pay dividends to the lender, makes short selling inherently challenging. Most short sellers target companies with accounting fraud, deteriorating fundamentals, unsustainable business models, or extreme overvaluation.

Despite its controversial reputation, short selling performs an important market function: it improves price discovery by allowing bearish views to be expressed in prices, provides liquidity, and has historically uncovered fraud (short sellers identified problems at Enron and Wirecard well before regulators). Countries that have banned short selling during crises have generally experienced worse market outcomes, not better.
