Therefore, if your stock gets called away, you have the shares in your account. You can sell covered calls to generate a stream of income. If the stock price does not rise enough during the period of the contract, you won't get called and won't have to sell the stock so you keep the money you received when you sold the call. If your broker lets you, you may sell "uncovered "or "naked" calls in a margin account. This practice lets you sell calls when you don't own the stock.

If you get called, you must buy the stock at its current market value to cover the call even when the market price is higher than the strike price of the option. Like any margin account transaction, you must execute the transaction immediately.

The seller has the obligation to buy shares at the strike price regardless of the market value of the underlying stock.

Niederhoffer was forced to shut down his firm. He had to mortgage his house. He had to borrow money from his children. He had to call Sotheby's and sell his prized silver collection Use calls and puts judiciously. If you're right, you can make quick money. If you're wrong, you can lose part or all of your investment very quickly. Do not sell "naked" options. You may be inviting a financial disaster. Knowledgeable, experienced investors may want to sell covered calls and puts to collect other peoples money.
