Market-implied 1-standard-deviation range extends from $82.33 to $91.93, which sets the relevant P&L evaluation window for most near-term strategies.

Frequently asked CSM pl curve questions

What does a CSM ATM straddle cost?
As of Oct 14, 2026, using CSM end-of-day pricing (19.2% ATM IV, 37-day front expiration, $87.13 spot), an at-the-money long straddle (long call + long put at the same strike) carries an approximate combined premium near $4.26 per spread. Breakevens land at roughly $91.39 on the upside and $82.87 on the downside. The estimate uses the Brenner-Subrahmanyam approximation for at-the-money options under Black-Scholes.
How do I read an options P&L curve?
An options P&L curve plots theoretical position value at expiration (or at any chosen evaluation date) against the underlying price. The X-axis is the underlying price scenario, the Y-axis is position dollar P&L. The shape of the curve tells you the strategy's directional sensitivity, breakeven points, maximum profit and loss levels, and where time decay or volatility shifts will be most impactful. Multi-leg structures combine the curves of the individual legs to produce composite payoff diagrams.
What's the difference between a P&L curve and a payoff diagram?
Strictly: a payoff diagram shows option value at expiration (no time premium left), while a P&L curve typically shows position value at any evaluation date (with remaining time premium). The expiration payoff diagram has kinks at the strikes; the early P&L curve is smooth. For directional-vega trades, the early P&L curve also responds to IV shifts that the expiration payoff diagram does not capture - which is why options traders often look at both views.
Why are illustrative CSM P&L numbers approximate?
The numbers above use Black-Scholes assumptions (lognormal returns, constant volatility, no early exercise, no dividends). Real-world option prices reflect skew, term structure, jump risk, and (for US-style options) early exercise premium. Use the live options chain for actual quoted bid/ask prices when sizing trades; the values here illustrate magnitude only.
