KRYS (Krystal Biotech, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $9.21B, a trailing P/E of 40.68, a beta of 0.50 versus the broader market, a 52-week range of 122.8-317.21, average daily share volume of 304K, a public-listing history dating back to 2017, approximately 275 full-time employees. These structural characteristics shape how KRYS stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.50 indicates KRYS 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 40.68 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.
What is a butterfly on KRYS?
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 KRYS snapshot
As of May 14, 2026, spot at $315.13, ATM IV 37.70%, IV rank 9.99%, expected move 10.81%. The butterfly on KRYS 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 KRYS specifically: KRYS IV at 37.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a KRYS butterfly, with a market-implied 1-standard-deviation move of approximately 10.81% (roughly $34.06 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 KRYS expiries trade a higher absolute premium for lower per-day decay. Position sizing on KRYS should anchor to the underlying notional of $315.13 per share and to the trader's directional view on KRYS stock.
KRYS butterfly setup
The KRYS 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 KRYS near $315.13, the first option leg uses a $300.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KRYS 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 KRYS shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $320.00 | $9.30 |
| Buy 1 | Call | $330.00 | $6.40 |

When traders use butterfly on KRYS
Butterflies on KRYS are pinning bets - traders use them when they expect KRYS 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.
KRYS thesis for this butterfly
The market-implied 1-standard-deviation range for KRYS extends from approximately $281.07 on the downside to $349.19 on the upside. A KRYS long call butterfly is a pinning play: it pays maximum at the middle strike if KRYS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current KRYS IV rank near 9.99% 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 KRYS at 37.70%. As a Healthcare name, KRYS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KRYS-specific events.
KRYS 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. KRYS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move KRYS alongside the broader basket even when KRYS-specific fundamentals are unchanged. Always rebuild the position from current KRYS chain quotes before placing a trade.
