Risks of Short Selling

4 min

Short selling carries unlimited risk. Unlike buying stocks (where you can only lose what you invest), shorting can lead to infinite losses.

Unlimited Loss Potential

When you buy a stock, the worst case is it goes to $0 and you lose your investment. When you short, there's no cap on how high the price can go. If you short at $50 and it rises to $500, you lose $450 per share.

The Short Squeeze

A short squeeze happens when a heavily shorted stock suddenly rises, forcing short sellers to buy back shares to limit losses. This buying pressure drives the price even higher, creating a feedback loop. GameStop in 2021 is a famous example.

Short Squeeze Cycle
  1. 1.Many traders short Stock XYZ
  2. 2.Good news sends price up 20%
  3. 3.Short sellers panic and buy to cover
  4. 4.Buying pressure drives price up another 30%
  5. 5.More shorts forced to cover, price soars

Margin Calls

Brokers require you to maintain a margin account when shorting. If the stock rises significantly, you may face a margin call—you must deposit more cash or close the position at a loss.

Key Takeaways
  • Shorting has unlimited loss potential—stocks can rise indefinitely
  • Short squeezes happen when rapid price increases force mass buying
  • Margin requirements add complexity and risk to short positions
