How it works
The short call premium pays for (most of) the put: downside is floored at the put strike, upside capped at the call strike.
When to use it
You want cheap protection on a long position and accept a ceiling — common for concentrated holdings.
Risks & management
Opportunity cost above the call strike. A zero-cost collar is never actually free: the cap is the price.
