Current SIGA snapshot
As of May 15, 2026, spot at $4.24, ATM IV 22.20%, IV rank 0.00%, expected move 6.36%. The covered call on SIGA 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 covered call structure on SIGA specifically: SIGA IV at 22.20% is on the cheap side of its 1-year range, which means a premium-selling SIGA covered call collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 6.36% (roughly $0.27 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 SIGA expiries trade a higher absolute premium for lower per-day decay. Position sizing on SIGA should anchor to the underlying notional of $4.24 per share and to the trader's directional view on SIGA stock.
SIGA covered call setup
The SIGA covered call below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SIGA near $4.24, the first option leg uses a $4.45 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SIGA 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 SIGA shares for the stock leg in covered calls and collars).

SIGA thesis for this covered call
The market-implied 1-standard-deviation range for SIGA extends from approximately $3.97 on the downside to $4.51 on the upside. A SIGA covered call collects premium on an existing long SIGA position, trading off upside above the short call strike for immediate income; the short strike selection should reflect the trader's view on whether SIGA will breach that level within the expiration window. Current SIGA IV rank near 0.00% 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 SIGA at 22.20%. As a Healthcare name, SIGA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SIGA-specific events.
SIGA covered call 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. SIGA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SIGA alongside the broader basket even when SIGA-specific fundamentals are unchanged. Short-premium structures like a covered call on SIGA carry tail risk when realized volatility exceeds the implied move; review historical SIGA earnings reactions and macro stress periods before sizing. Always rebuild the position from current SIGA chain quotes before placing a trade.
