When a short call is assigned, the seller is obligated to sell 100 shares of the underlying stock at the strike price, even if they don't own them, creating a short stock position in their account that they must cover (buy shares to return) to close the obligation. This typically happens when the stock price is above the strike price (in-the-money) at expiration or due to early assignment, resulting in selling shares at a loss if the market price is higher than the strike price.
