Worked Examples

Load these examples to compare common covered strangle payoff outcomes.

COVERED STRANGLE

Model stock plus two short options

The stock finishes between the short strikes.

  • Enter the manual prices and assumptions.
  • Review the calculated risk, reward, and break-even metrics.
  • Compare the chart with the highlighted scenario.

Result: the calculator updates the scenario metrics and chart from those inputs.

Real fills, fees, and broker margin rules are not modeled.

How It Works

A covered strangle owns stock, sells an upside call, and sells a downside put.

Example Problem

Own 100 shares, sell one OTM call, and sell one OTM put.

  1. Add call and put premiums.
  2. Calculate stock profit or loss.
  3. Subtract option obligations.
  4. Check call or put assignment zones.

A covered strangle can double downside share exposure if the short put is assigned.

Key Concepts

Premium widens break-even, the short call caps upside, and the short put adds downside assignment risk.

Applications

  • Income planning around stock holdings.
  • Checking assignment outcomes.
  • Comparing wheel-like stock positions.

Common Mistakes

  • Ignoring added downside from the short put.
  • Assuming covered means risk-free.
  • Forgetting upside is capped.
