FDMT snapshot
As of August 14, 2026, spot at $12.09, ATM IV 105.00%, IV rank 20.99%, expected move 30.10%. The bear put spread 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 bear put spread 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 bear put spread, 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 bear put spread setup
The FDMT bear put spread 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 | Put | $12.00 | $1.76 |
| Sell 1 | Put | $11.00 | $1.24 |

FDMT thesis for this bear put spread
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 bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on FDMT, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. 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 bear put spread positions are structurally moderately bearish; 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. Long-premium structures like a bear put spread on FDMT are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current FDMT chain quotes before placing a trade.
