How are NPO strangle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the put strike minus the combined debit (reached at zero). Max loss equals the combined debit times 100 (reached anywhere between the two OTM strikes). Two breakevens at call-strike plus debit and put-strike minus debit. For the NPO strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 40.00%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$1,100.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a NPO strangle?

The breakeven for the NPO strangle priced on this page is roughly $339.00 and $401.00 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current NPO market-implied 1-standard-deviation expected move is approximately 11.47%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current NPO implied volatility affect this strangle?

NPO ATM IV is at 40.00% with IV rank near 35.65%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

NPO Strangle Strategy

NPO (EnPro Industries, Inc.), in the Industrials sector, (Industrial - Machinery industry), listed on NYSE.

EnPro Industries, Inc. is a global enterprise focused on the development, manufacturing, sales, and support of advanced industrial components. Its operations span the United States, Europe, and numerous other international regions. The company's business activities are structured into three primary divisions: Sealing Technologies, Advanced Surface Technologies, and Engineered Materials. The Sealing Technologies segment delivers a wide array of sealing solutions. These include hygienic seals, tubing, and complete assemblies for single-use applications; various gaskets fabricated from metallic, non-metallic, or composite materials; compression packing; hydraulic parts; expansion joints; and products for wall penetration. It also supplies an extensive selection of mechanical seals, such as dynamic, flange, resilient metal, elastomeric, and custom-designed types.

NPO (EnPro Industries, Inc.) trades in the Industrials sector, specifically Industrial - Machinery, with a market capitalization of approximately $8.01B, a trailing P/E of 184.39, a beta of 1.55 versus the broader market, a 52-week range of 189.31-390.42, average daily share volume of 268K, a public-listing history dating back to 2002, approximately 4K full-time employees. These structural characteristics shape how NPO stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.55 indicates NPO has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 184.39 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. NPO pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a strangle on NPO?

A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.

Current NPO snapshot

As of June 29, 2026, spot at $372.11, ATM IV 40.00%, IV rank 35.65%, expected move 11.47%. The strangle on NPO below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 18-day expiry.

Why this strangle structure on NPO specifically: NPO IV at 40.00% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 11.47% (roughly $42.67 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated NPO expiries trade a higher absolute premium for lower per-day decay. Position sizing on NPO should anchor to the underlying notional of $372.11 per share and to the trader's directional view on NPO stock.

NPO strangle setup

The NPO strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With NPO near $372.11, the first option leg uses a $390.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed NPO chain at a 18-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 NPO shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$390.00	$5.65
Buy 1	Put	$350.00	$5.35

When traders use strangle on NPO

Strangles on NPO are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the NPO chain.

NPO thesis for this strangle

The market-implied 1-standard-deviation range for NPO extends from approximately $329.44 on the downside to $414.78 on the upside. A NPO long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current NPO IV rank near 35.65% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on NPO should anchor more to the directional view and the expected-move geometry. As a Industrials name, NPO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to NPO-specific events.

NPO strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. NPO positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move NPO alongside the broader basket even when NPO-specific fundamentals are unchanged. Always rebuild the position from current NPO chain quotes before placing a trade.
