Current FLNA snapshot
As of May 15, 2026, spot at $1.19, ATM IV 20.40%, expected move 5.85%. The bear put spread on FLNA 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 245-day expiry.
Why this bear put spread structure on FLNA specifically: IV rank is unavailable in the current snapshot, so regime-based timing for FLNA is inferred from ATM IV at 20.40% alone, with a market-implied 1-standard-deviation move of approximately 5.85% (roughly $0.07 on the underlying). The 245-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FLNA expiries trade a higher absolute premium for lower per-day decay. Position sizing on FLNA should anchor to the underlying notional of $1.19 per share and to the trader's directional view on FLNA stock.
FLNA bear put spread setup
The FLNA bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With FLNA near $1.19, the first option leg uses a $1.19 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FLNA chain at a 245-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 FLNA shares for the stock leg in covered calls and collars).

FLNA thesis for this bear put spread
The market-implied 1-standard-deviation range for FLNA extends from approximately $1.12 on the downside to $1.26 on the upside. A FLNA bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on FLNA, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Healthcare name, FLNA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FLNA-specific events.
FLNA 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. FLNA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FLNA alongside the broader basket even when FLNA-specific fundamentals are unchanged. Long-premium structures like a bear put spread on FLNA 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 FLNA chain quotes before placing a trade.
