LLY (Eli Lilly and Company) trades in the Healthcare sector, specifically Drug Manufacturers - General, with a market capitalization of approximately $1.15T, a trailing P/E of 40.78, a beta of 0.51 versus the broader market, a 52-week range of 644.5-1249.45, average daily share volume of 3.1M, a public-listing history dating back to 1972, approximately 50K full-time employees. These structural characteristics shape how LLY stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.51 indicates LLY has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 40.78 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. LLY pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on LLY?
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.
LLY snapshot
As of August 14, 2026, spot at $1,178.20, ATM IV 28.57%, IV rank 13.44%, expected move 8.19%. The butterfly on LLY 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 28-day expiry.
Why this butterfly structure on LLY specifically: LLY IV at 28.57% is on the cheap side of its 1-year range, which favors premium-buying structures like a LLY butterfly, with a market-implied 1-standard-deviation move of approximately 8.19% (roughly $96.50 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 LLY expiries trade a higher absolute premium for lower per-day decay. Position sizing on LLY should anchor to the underlying notional of $1,178.20 per share and to the trader's directional view on LLY stock.
LLY butterfly setup
The LLY butterfly 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 LLY at $1,178.20 on that close, the first option leg uses a $1,120.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed LLY 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 LLY shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $1,180.00 | $37.95 |
| Buy 1 | Call | $1,235.00 | $19.63 |

When traders use butterfly on LLY
Butterflies on LLY are pinning bets - traders use them when they expect LLY to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
LLY thesis for this butterfly
The market-implied 1-standard-deviation range for LLY extends from approximately $1,081.70 on the downside to $1,274.70 on the upside. A LLY long call butterfly is a pinning play: it pays maximum at the middle strike if LLY settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current LLY IV rank near 13.44% 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 LLY at 28.57%. As a Healthcare name, LLY options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to LLY-specific events.
LLY 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. LLY positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move LLY alongside the broader basket even when LLY-specific fundamentals are unchanged. Always rebuild the position from current LLY chain quotes before placing a trade.
