THRM (Gentherm Incorporated) trades in the Consumer Cyclical sector, specifically Auto - Parts, with a market capitalization of approximately $943.3M, a trailing P/E of 41.48, a beta of 1.35 versus the broader market, a 52-week range of 25.76-39.48, average daily share volume of 267K, a public-listing history dating back to 1993, approximately 14K full-time employees. These structural characteristics shape how THRM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 1.35 indicates THRM 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 41.48 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.
What is a straddle on THRM?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.
Current THRM snapshot
As of May 15, 2026, spot at $30.26, ATM IV 56.80%, IV rank 12.76%, expected move 16.28%. The straddle on THRM 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 straddle structure on THRM specifically: THRM IV at 56.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a THRM straddle, with a market-implied 1-standard-deviation move of approximately 16.28% (roughly $4.93 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 THRM expiries trade a higher absolute premium for lower per-day decay. Position sizing on THRM should anchor to the underlying notional of $30.26 per share and to the trader's directional view on THRM stock.
THRM straddle setup
The THRM straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With THRM near $30.26, the first option leg uses a $30.26 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed THRM 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 THRM shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

| Buy 1 | Put | $30.26 | N/A |

When traders use straddle on THRM

THRM thesis for this straddle
The market-implied 1-standard-deviation range for THRM extends from approximately $25.33 on the downside to $35.19 on the upside. A THRM long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current THRM IV rank near 12.76% 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 THRM at 56.80%. As a Consumer Cyclical name, THRM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to THRM-specific events.
THRM straddle positions are structurally neutral / high-volatility (long premium); 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. THRM positions also carry Consumer Cyclical sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move THRM alongside the broader basket even when THRM-specific fundamentals are unchanged. Always rebuild the position from current THRM chain quotes before placing a trade.
Frequently asked questions
- What is a straddle on THRM?

- How are THRM straddle max profit and max loss calculated?

- What is the breakeven for a THRM straddle?
- The breakeven for the THRM straddle 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 THRM market-implied 1-standard-deviation expected move is approximately 16.28%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
