Current SERA snapshot
As of May 15, 2026, spot at $1.76, ATM IV 234.40%, IV rank 50.44%, expected move 67.20%. The cash-secured put on SERA 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 cash-secured put structure on SERA specifically: SERA IV at 234.40% is mid-range versus its 1-year history, so the credit collected on a SERA cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 67.20% (roughly $1.18 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 SERA expiries trade a higher absolute premium for lower per-day decay. Position sizing on SERA should anchor to the underlying notional of $1.76 per share and to the trader's directional view on SERA stock.
SERA cash-secured put setup
The SERA cash-secured put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SERA near $1.76, the first option leg uses a $1.67 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SERA 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 SERA shares for the stock leg in covered calls and collars).

SERA thesis for this cash-secured put
The market-implied 1-standard-deviation range for SERA extends from approximately $0.58 on the downside to $2.94 on the upside. A SERA cash-secured put lets a trader earn premium while waiting to acquire SERA 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 SERA IV rank near 50.44% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on SERA should anchor more to the directional view and the expected-move geometry. As a Healthcare name, SERA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SERA-specific events.
SERA 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. SERA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SERA alongside the broader basket even when SERA-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on SERA carry tail risk when realized volatility exceeds the implied move; review historical SERA earnings reactions and macro stress periods before sizing. Always rebuild the position from current SERA chain quotes before placing a trade.
