Bullish strategy · Scenario Lab
Market outlook Bullish
A call purchase with defined premium at risk and open-ended upside at expiration. Use the lab to see how the position responds before committing to a single forecast.
Scenario Lab
Move the underlying, clock, and implied volatility independently. Values before expiration use a Black–Scholes estimate; expiration values use intrinsic payoff.
The catalog’s default strikes and premiums are illustrative. No ticker lookup or market data is used.

At expiration
Time value has gone to zero. IV no longer changes the result.

Model boundary: theoretical estimates use dividend-adjusted Black–Scholes for European exercise or a 100-step binomial estimate for American exercise. Fees, spreads, discrete dividend dates, early assignment behavior, and liquidity effects are excluded. Calculation, not advice.
Why this structure behaves this way
Pure directional long exposure. Decays daily against you but IV expansion and accelerating gamma near the strike work in your favor as the stock approaches it.
This page uses the catalog’s illustrative default legs so you can compare direction, time, and volatility effects in one place. Edit the assumptions above to test a different starting point.
