KNSA snapshot

As of August 14, 2026, spot at $76.72, ATM IV 50.50%, IV rank 28.78%, expected move 14.48%. The cash-secured put on KNSA 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 63-day expiry.

Why this cash-secured put structure on KNSA specifically: KNSA IV at 50.50% is on the cheap side of its 1-year range, which means a premium-selling KNSA cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 14.48% (roughly $11.11 on the underlying). The 63-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated KNSA expiries trade a higher absolute premium for lower per-day decay. Position sizing on KNSA should anchor to the underlying notional of $76.72 per share and to the trader's directional view on KNSA stock.

KNSA cash-secured put setup

The KNSA cash-secured put 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 KNSA at $76.72 on that close, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KNSA chain at a 63-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 KNSA shares for the stock leg in covered calls and collars).

KNSA thesis for this cash-secured put

The market-implied 1-standard-deviation range for KNSA extends from approximately $65.61 on the downside to $87.83 on the upside. A KNSA cash-secured put lets a trader earn premium while waiting to acquire KNSA at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current KNSA IV rank near 28.78% 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 KNSA at 50.50%. As a Healthcare name, KNSA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KNSA-specific events.

KNSA cash-secured put positions are structurally neutral to slightly bullish; 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. KNSA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move KNSA alongside the broader basket even when KNSA-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on KNSA carry tail risk when realized volatility exceeds the implied move; review historical KNSA earnings reactions and macro stress periods before sizing. Always rebuild the position from current KNSA chain quotes before placing a trade.
