A strategy for when you are somewhat bullish but nervous on a stock, and own 100 of the underlying shares. It is like a covered call and protective put combined because it protects you from the stock falling past strike A, but also limits your upside by selling the stock if it hits strike B.

You can also think of it like a protective put, but the credit from the short call pays for the stop-loss insurance, with the downside of the profit being capped.
