What is a butterfly on GALT?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
Current GALT snapshot
As of May 15, 2026, spot at $2.23, ATM IV 177.80%, IV rank 45.88%, expected move 50.97%. The butterfly on GALT 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 butterfly structure on GALT specifically: GALT IV at 177.80% 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 50.97% (roughly $1.14 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 GALT expiries trade a higher absolute premium for lower per-day decay. Position sizing on GALT should anchor to the underlying notional of $2.23 per share and to the trader's directional view on GALT stock.
GALT butterfly setup
The GALT butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With GALT near $2.23, the first option leg uses a $2.12 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GALT 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 GALT shares for the stock leg in covered calls and collars).

GALT thesis for this butterfly
The market-implied 1-standard-deviation range for GALT extends from approximately $1.09 on the downside to $3.37 on the upside. A GALT long call butterfly is a pinning play: it pays maximum at the middle strike if GALT settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current GALT IV rank near 45.88% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on GALT should anchor more to the directional view and the expected-move geometry. As a Healthcare name, GALT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GALT-specific events.
GALT butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. GALT positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GALT alongside the broader basket even when GALT-specific fundamentals are unchanged. Always rebuild the position from current GALT chain quotes before placing a trade.
