ALMS bear put spread setup

The ALMS 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 ALMS near $23.05, the first option leg uses a $23.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets.

Quantity sizing assumes one contract per option leg (or 100 ALMS shares for the stock leg in covered calls and collars).

ALMS thesis for this bear put spread

The market-implied 1-standard-deviation range for ALMS extends from approximately $17.65 on the downside to $28.45 on the upside. A ALMS bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on ALMS, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current ALMS IV rank near 9.07% 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 ALMS at 81.70%. As a Healthcare name, ALMS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ALMS-specific events.

ALMS 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. ALMS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ALMS alongside the broader basket even when ALMS-specific fundamentals are unchanged. Long-premium structures like a bear put spread on ALMS 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 ALMS chain quotes before placing a trade.
