Current NKTX snapshot

As of May 15, 2026, spot at $2.67, ATM IV 111.60%, IV rank 37.71%, expected move 31.99%. The bear put spread on NKTX 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 34-day expiry.

Why this bear put spread structure on NKTX specifically: NKTX IV at 111.60% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 31.99% (roughly $0.85 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated NKTX expiries trade a higher absolute premium for lower per-day decay. Position sizing on NKTX should anchor to the underlying notional of $2.67 per share and to the trader's directional view on NKTX stock.

NKTX bear put spread setup

The NKTX 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 NKTX near $2.67, the first option leg uses a $2.67 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed NKTX chain at a 34-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 NKTX shares for the stock leg in covered calls and collars).

A NKTX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on NKTX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit.

As a Healthcare name, NKTX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to NKTX-specific events.

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