Figures are conceptual for the classic structure. Your actual premiums, strikes, and fees change the numbers — confirm on the calculator.

When traders use it

  • You want income and/or are happy to own the stock at an effective discount (strike − premium).
  • You are bullish to neutral and avoid naked undefined margin structures.

Key risks

  • Assignment into a falling stock concentrates risk in shares.
  • Opportunity cost of cash locked as collateral.

Practical tips

  • Only sell puts on names you want to own.
  • Ladder strikes/expirations rather than concentrating all cash on one short put.
