Current REGN snapshot
As of May 15, 2026, spot at $698.66, ATM IV 36.86%, IV rank 46.63%, expected move 10.57%. The bull call spread on REGN 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 28-day expiry.
Why this bull call spread structure on REGN specifically: REGN IV at 36.86% 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 10.57% (roughly $73.84 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated REGN expiries trade a higher absolute premium for lower per-day decay. Position sizing on REGN should anchor to the underlying notional of $698.66 per share and to the trader's directional view on REGN stock.
REGN bull call spread setup
The REGN bull call spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With REGN near $698.66, the first option leg uses a $700.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed REGN chain at a 28-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 REGN shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $700.00 | $28.50 |

REGN thesis for this bull call spread
The market-implied 1-standard-deviation range for REGN extends from approximately $624.82 on the downside to $772.50 on the upside. A REGN bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on REGN, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current REGN IV rank near 46.63% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on REGN should anchor more to the directional view and the expected-move geometry. As a Healthcare name, REGN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to REGN-specific events.
REGN bull call spread positions are structurally moderately 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. REGN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move REGN alongside the broader basket even when REGN-specific fundamentals are unchanged. Long-premium structures like a bull call spread on REGN are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current REGN chain quotes before placing a trade.
