What is a straddle on FDMT?
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.
FDMT snapshot
As of August 14, 2026, spot at $12.09, ATM IV 105.00%, IV rank 20.99%, expected move 30.10%. The straddle on FDMT 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 FDMT specifically: FDMT IV at 105.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a FDMT straddle, with a market-implied 1-standard-deviation move of approximately 30.10% (roughly $3.64 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 FDMT expiries trade a higher absolute premium for lower per-day decay. Position sizing on FDMT should anchor to the underlying notional of $12.09 per share and to the trader's directional view on FDMT stock.
FDMT straddle setup
The FDMT 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 FDMT at $12.09 on that close, the first option leg uses a $12.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FDMT 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 FDMT shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $12.00 | $1.86 |
| Buy 1 | Put | $12.00 | $1.76 |

When traders use straddle on FDMT
Straddles on FDMT are pure-volatility plays that profit from large moves in either direction; traders typically buy FDMT straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
FDMT thesis for this straddle
The market-implied 1-standard-deviation range for FDMT extends from approximately $8.45 on the downside to $15.73 on the upside. A FDMT 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 FDMT IV rank near 20.99% 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 FDMT at 105.00%. As a Healthcare name, FDMT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FDMT-specific events.
FDMT 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. FDMT positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FDMT alongside the broader basket even when FDMT-specific fundamentals are unchanged. Always rebuild the position from current FDMT chain quotes before placing a trade.
