FBRX snapshot
As of August 14, 2026, spot at $76.85, ATM IV 15.70%, IV rank 1.39%, expected move 4.50%. The straddle on FBRX below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 7-day expiry.
Why this straddle structure on FBRX specifically: FBRX IV at 15.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a FBRX straddle, with a market-implied 1-standard-deviation move of approximately 4.50% (roughly $3.46 on the underlying). The 7-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FBRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on FBRX should anchor to the underlying notional of $76.85 per share and to the trader's directional view on FBRX stock.
FBRX straddle setup
The FBRX straddle below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With FBRX at $76.85 on that close, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FBRX chain at a 7-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 FBRX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $75.00 | $2.37 |
| Buy 1 | Put | $75.00 | $0.47 |

When traders use straddle on FBRX
Straddles on FBRX are pure-volatility plays that profit from large moves in either direction; traders typically buy FBRX straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
FBRX thesis for this straddle
The market-implied 1-standard-deviation range for FBRX extends from approximately $73.39 on the downside to $80.31 on the upside. A FBRX 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 FBRX IV rank near 1.39% 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 FBRX at 15.70%. As a Healthcare name, FBRX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FBRX-specific events.
FBRX 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. FBRX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FBRX alongside the broader basket even when FBRX-specific fundamentals are unchanged. Always rebuild the position from current FBRX chain quotes before placing a trade.
