SEPN snapshot
As of August 14, 2026, spot at $44.70, ATM IV 74.30%, IV rank 12.55%, expected move 21.30%. The iron condor on SEPN 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 35-day expiry.
Why this iron condor structure on SEPN specifically: SEPN IV at 74.30% is on the cheap side of its 1-year range, which means a premium-selling SEPN iron condor collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 21.30% (roughly $9.52 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SEPN expiries trade a higher absolute premium for lower per-day decay. Position sizing on SEPN should anchor to the underlying notional of $44.70 per share and to the trader's directional view on SEPN stock.
SEPN iron condor setup
The SEPN iron condor 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 SEPN at $44.70 on that close, the first option leg uses a $47.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SEPN chain at a 35-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 SEPN shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Sell 1 | Call | $47.00 | $3.45 |
| Buy 1 | Call | $49.00 | $2.90 |
| Sell 1 | Put | $42.00 | $2.70 |
| Buy 1 | Put | $40.00 | $3.35 |

SEPN thesis for this iron condor
The market-implied 1-standard-deviation range for SEPN extends from approximately $35.18 on the downside to $54.22 on the upside. A SEPN iron condor is a delta-neutral premium-collection structure that pays off when SEPN stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current SEPN IV rank near 12.55% 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 SEPN at 74.30%. As a Healthcare name, SEPN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SEPN-specific events.
SEPN iron condor positions are structurally neutral / range-bound; 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. SEPN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SEPN alongside the broader basket even when SEPN-specific fundamentals are unchanged. Short-premium structures like a iron condor on SEPN carry tail risk when realized volatility exceeds the implied move; review historical SEPN earnings reactions and macro stress periods before sizing. Always rebuild the position from current SEPN chain quotes before placing a trade.
