Sell a call. Buy a put. Sell a put.</strong></p> <p>These are not four unrelated strategies. They are combinations of two choices:</p> <ul> <li>Are you trading a <strong>call</strong> or a <strong>put</strong>?</li> <li>Are you <strong>buying</strong> it or <strong>selling</strong> it?</li> </ul> <p>To understand these four basic positions, start with one idea: <strong>an option gives its buyer a right to transact in the future. Trading that right is different from buying or selling the asset itself.</strong></p>
