Foster Company) trades in the Industrials sector, specifically Railroads, with a market capitalization of approximately $428.0M, a trailing P/E of 37.41, a beta of 1.06 versus the broader market, a 52-week range of 18.18-42.53, average daily share volume of 82K, a public-listing history dating back to 1981, approximately 1K full-time employees.

What is a strangle on FSTR?
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 FSTR snapshot
As of May 15, 2026, spot at $38.91, ATM IV 55.70%, IV rank 20.81%, expected move 15.97%. The strangle on FSTR 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 34-day expiry.
Why this strangle structure on FSTR specifically: FSTR IV at 55.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a FSTR strangle, with a market-implied 1-standard-deviation move of approximately 15.97% (roughly $6.21 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FSTR expiries trade a higher absolute premium for lower per-day decay. Position sizing on FSTR should anchor to the underlying notional of $38.91 per share and to the trader's directional view on FSTR stock.
FSTR strangle setup
The FSTR 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 FSTR near $38.91, the first option leg uses a $40.86 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FSTR chain at a 34-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 FSTR shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $40.86 | N/A |
| Buy 1 | Put | $36.96 | N/A |
FSTR strangle risk and reward
- Net Premium / Debit
- N/A
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)
- Unbounded
- Breakeven(s)
- None on modeled curve
- Risk / Reward Ratio
- N/A
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.

When traders use strangle on FSTR
Strangles on FSTR 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 FSTR chain.
FSTR thesis for this strangle
The market-implied 1-standard-deviation range for FSTR extends from approximately $32.70 on the downside to $45.12 on the upside. A FSTR 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 FSTR IV rank near 20.81% 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 FSTR at 55.70%. As a Industrials name, FSTR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FSTR-specific events.
FSTR 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. FSTR positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FSTR alongside the broader basket even when FSTR-specific fundamentals are unchanged. Always rebuild the position from current FSTR chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on FSTR?
- A strangle on FSTR is the strangle strategy applied to FSTR (stock). The strategy is structurally neutral / high-volatility (long premium, OTM): 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. With FSTR stock trading near $38.91, the strikes shown on this page are snapped to the nearest listed FSTR chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are FSTR 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 FSTR strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 55.70%), 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 FSTR strangle?
- The breakeven for the FSTR strangle priced on this page is no defined breakeven on the modeled curve 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 FSTR market-implied 1-standard-deviation expected move is approximately 15.97%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on FSTR?
- Strangles on FSTR 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 FSTR chain.
- How does current FSTR implied volatility affect this strangle?
- FSTR ATM IV is at 55.70% with IV rank near 20.81%, 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.
