Introduction to Short Selling

Short selling is an investment strategy that profits from the decline in a stock's price. Unlike buying low and selling high, short selling involves selling high with the expectation of buying back low. It is used to capitalize on bearish sentiment or hedge against downside risk in an existing portfolio. While potentially profitable, short selling carries substantial risk due to the unlimited nature of potential losses.

Questions worth resolving before acting on the screen

What are the risks of short selling?

Short selling carries unlimited risk, as a stock's price can theoretically rise indefinitely. Short sellers may also face margin calls if the stock price increases, requiring them to deposit additional funds to cover potential losses.

How is short selling different from buying stocks?

Buying stocks involves purchasing shares with the expectation that their value will increase over time. Short selling, conversely, involves borrowing shares and selling them, anticipating a price decrease to repurchase them at a lower cost.

What is a short squeeze?

A short squeeze occurs when a stock with high short interest experiences a rapid price increase, forcing short sellers to cover their positions by buying back the stock. This can lead to further price increases, exacerbating losses for short sellers.
