What is a straddle on SERA?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.
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 straddle 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 straddle structure on SERA specifically: SERA IV at 234.40% 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 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 straddle setup
The SERA straddle 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 $1.76 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).
| Action | Type | Strike / Basis | Premium (est) |

| Buy 1 | Put | $1.76 | N/A |

When traders use straddle on SERA

SERA thesis for this straddle
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 long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current SERA IV rank near 50.44% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle 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 straddle positions are structurally neutral / high-volatility (long premium); 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. Always rebuild the position from current SERA chain quotes before placing a trade.
