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
Collar is shaped by positive delta and short vega exposure
Net long delta from the stock, trimmed by the short call and long put. In a typical zero-cost setup the short call's theta and gamma dominate, giving small net positive theta and negative vega — the trade-off for the put's downside floor.
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.
