Side by side
- Covered call: own the stock, cap your upside at the strike, keep the premium.
- Cash-secured put: no stock yet, may buy shares at the strike, keep the premium.
- Both lose money if the stock falls sharply; the premium only cushions the loss.
- Used together in a cycle, this is often called "the wheel".
Choosing strikes (examples, not advice)
- Covered call: a strike above recent resistance or the call wall.
- Cash-secured put: a strike at a price where you would be happy to own the stock.
- Avoid holding either through earnings unless you accept a large gap.
