As of Aug 14, 2026, with a $63.23 spot price, 75.4% ATM implied volatility, and 35 days to the front expiration, an at-the-money long straddle carries an approximate combined premium near $11.81, producing breakevens at roughly $51.42 and $75.04. Market-implied 1-standard-deviation range extends from $49.56 to $76.90, which sets the relevant P&L evaluation window for most near-term strategies. Payoff diagrams should be rebuilt from the live options chain; the preceding values are illustrative and assume a single at-the-money straddle for reference.
Frequently asked SEI pl curve questions
- What does a SEI ATM straddle cost?
- As of Aug 14, 2026, using SEI end-of-day pricing (75.4% ATM IV, 35-day front expiration, $63.23 spot), an at-the-money long straddle (long call + long put at the same strike) carries an approximate combined premium near $11.81 per spread. Breakevens land at roughly $75.04 on the upside and $51.42 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 SEI 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.
