EXPO (Exponent, Inc.) trades in the Industrials sector, specifically Engineering & Construction, with a market capitalization of approximately $3.28B, a trailing P/E of 29.50, a beta of 0.69 versus the broader market, a 52-week range of 51.91-81.95, average daily share volume of 557K, a public-listing history dating back to 1990, approximately 1K full-time employees. These structural characteristics shape how EXPO stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on EXPO?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
EXPO snapshot
As of August 14, 2026, spot at $67.21, ATM IV 26.10%, IV rank 1.96%, expected move 7.48%. The butterfly on EXPO below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on EXPO specifically: EXPO IV at 26.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a EXPO butterfly, with a market-implied 1-standard-deviation move of approximately 7.48% (roughly $5.03 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EXPO expiries trade a higher absolute premium for lower per-day decay. Position sizing on EXPO should anchor to the underlying notional of $67.21 per share and to the trader's directional view on EXPO stock.
EXPO butterfly setup
The EXPO butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With EXPO at $67.21 on that close, the first option leg uses a $63.85 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EXPO chain at a 35-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 EXPO shares for the stock leg in covered calls and collars).

| Buy 1 | Call | $70.57 | N/A |

When traders use butterfly on EXPO
Butterflies on EXPO are pinning bets - traders use them when they expect EXPO to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
EXPO thesis for this butterfly
The market-implied 1-standard-deviation range for EXPO extends from approximately $62.18 on the downside to $72.24 on the upside. A EXPO long call butterfly is a pinning play: it pays maximum at the middle strike if EXPO settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current EXPO IV rank near 1.96% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on EXPO at 26.10%. As a Industrials name, EXPO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EXPO-specific events.
EXPO butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. EXPO positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move EXPO alongside the broader basket even when EXPO-specific fundamentals are unchanged. Always rebuild the position from current EXPO chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on EXPO?
- A butterfly on EXPO is the butterfly strategy applied to EXPO (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration. With EXPO stock at $67.21 on the most recent close, the strikes shown on this page are snapped to the nearest listed EXPO chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are EXPO butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the EXPO butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 26.10%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a EXPO butterfly?
- The breakeven for the EXPO butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The EXPO market-implied 1-standard-deviation expected move in the same options snapshot is approximately 7.48%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on EXPO?
- Butterflies on EXPO are pinning bets - traders use them when they expect EXPO to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
- How does current EXPO implied volatility affect this butterfly?
- EXPO ATM IV is at 26.10% with IV rank near 1.96%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
