Why Is Selling OTM Options a Common Strategy for Collecting Premium Income?
Selling OTM options (shorting) is popular because of the high probability that the option will expire worthless. Since OTM options have zero intrinsic value and their time value constantly decays (Theta decay), the seller benefits from both time and the price staying below the Call strike or above the Put strike.
The goal is to collect the entire premium as profit with a high statistical edge.
