How to protect a short call?

What are the risks of shorting?

Short selling is risky because losses are theoretically unlimited, as a stock price can rise indefinitely, unlike a long position where the maximum loss is 100% of the investment. Key risks include short squeezes, where rising prices force short sellers to buy back shares, pushing prices even higher; margin calls requiring more funds; borrowing costs, dividends, and potential regulatory bans.
