And the shares? Are they covered too to the downside?
Well no that's why a covered call has the same payoff pattern as a short put. But usually with a covered call, people already own the stock so the shares's downside not being covered is a given. The point in a covered call is that the short call is covered hence the term "covered call". If you want to protect the underlying stock's downside, you can buy a protective put. I hope that answered your question.
