Short selling flips investing upside down: you sell first and buy back later, profiting if the price falls. It's powerful, advanced, and carries unlimited risk.
Short selling is a way to profit when a stock falls. You borrow shares from a broker, sell them at today's price, and aim to buy them back later — to cover — at a lower price. You return the borrowed shares and keep the difference. It's ordinary trading run in reverse: sell high first, buy low second.
Traders short to profit from declines in companies they think are overvalued or failing, and investors use shorts to hedge — offsetting potential losses elsewhere in a portfolio. Short sellers also act as skeptics who can expose frauds and rein in bubbles, though they're often unpopular when they're right.
Here's what makes shorting advanced. When you buy a stock, the most you can lose is 100% — it can only fall to zero. When you short, your loss is theoretically unlimited, because a stock can rise forever. Your potential gain is capped (the stock can't fall below zero) while your loss is open-ended — the opposite of normal investing.
Short squeeze risk: if a heavily shorted stock starts rising, panicked shorts rushing to cover can drive the price even higher, forcing more buying in a self-reinforcing spike. Squeezes have inflicted brutal losses on short sellers.
Because of all this, shorting is generally for experienced traders who size positions small and manage risk tightly. The safest way to learn the mechanics is with play money.
Try it risk-free: Short a simulated stock, cover lower, and feel the asymmetric risk in the short selling game with play money — no sign-up, no real risk.

It is profiting when a stock falls. You borrow shares, sell them at today's price, then buy them back lower to return them — keeping the difference. It is trading in reverse: sell high first, buy low later.
Because the loss is theoretically unlimited — a stock can rise forever — while the gain is capped since a stock cannot fall below zero. That asymmetry makes shorting far riskier than buying.
When a heavily shorted stock rises, short sellers rushing to buy back shares to cut losses can push the price even higher, triggering more buying in a self-reinforcing spike that can cause huge losses.
No. The short selling game uses a seeded random-walk price and play money saved in your browser. It teaches the mechanics risk-free and is not financial advice.
