AVLN snapshot
As of September 29, 2026, spot at $27.34, ATM IV 48.80%, expected move 13.99%. The bear put spread on AVLN below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 17-day expiry.
Why this bear put spread structure on AVLN specifically: IV rank is unavailable in the current snapshot, so regime-based timing for AVLN is inferred from ATM IV at 48.80% alone, with a market-implied 1-standard-deviation move of approximately 13.99% (roughly $3.83 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated AVLN expiries trade a higher absolute premium for lower per-day decay. Position sizing on AVLN should anchor to the underlying notional of $27.34 per share and to the trader's directional view on AVLN stock.
AVLN bear put spread setup
The AVLN 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 AVLN at $27.34 on that close, the first option leg uses a $27.34 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed AVLN chain at a 17-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 AVLN shares for the stock leg in covered calls and collars).

AVLN thesis for this bear put spread
The market-implied 1-standard-deviation range for AVLN extends from approximately $23.51 on the downside to $31.17 on the upside. A AVLN bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on AVLN, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Healthcare name, AVLN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to AVLN-specific events.
AVLN 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. AVLN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move AVLN alongside the broader basket even when AVLN-specific fundamentals are unchanged. Long-premium structures like a bear put spread on AVLN 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.
