What is a covered call strategy and how can it be used to generate income in the money?

A covered call strategy is when an investor owns a stock and sells a call option on that stock. This strategy can generate income by collecting the premium from selling the call option. If the stock price remains below the strike price of the call option, the investor keeps the premium as profit. If the stock price rises above the strike price, the investor may have to sell the stock at the strike price but still keeps the premium received.
