Market outlook Large move either way

Long call and put at same strike benefit from large move. Use the lab to see how the position responds before committing to a single forecast.

Move the underlying, clock, and implied volatility independently. Values before expiration use a Black–Scholes estimate; expiration values use intrinsic payoff.

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

Long Straddle is shaped by neutral delta and long vega exposure

Delta-neutral at entry with maximum gamma and vega of any two-leg structure at this strike. Theta decay is the steepest of any long-premium play, since both legs bleed simultaneously while the stock sits still.
