CRSP Butterfly Strategy
CRSP (CRISPR Therapeutics AG), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
CRISPR Therapeutics AG, a gene editing company, focuses on developing gene-based medicines for serious diseases using its proprietary Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) platform. Its CRISPR/Cas9 is a gene editing technology that allows for precise directed changes to genomic DNA. The company has a portfolio of therapeutic programs across a range of disease areas, including hemoglobinopathies, oncology, regenerative medicine, and rare diseases. The company's lead product candidate is CTX001, an ex vivo CRISPR gene-edited therapy for treating patients suffering from transfusion-dependent beta-thalassemia or severe sickle cell disease in which a patient's hematopoietic stem cells are engineered to produce high levels of fetal hemoglobin in red blood cells. It also develops CTX110, a donor-derived gene-edited allogeneic CAR-T investigational therapy targeting cluster of differentiation 19 positive malignancies; CTX120, a donor-derived gene-edited allogeneic CAR-T investigational therapy targeting B-cell maturation antigen for the treatment of relapsed or refractory multiple myeloma; and CTX130, a donor-derived gene-edited allogeneic CAR-T investigational therapy targeting Cluster of Differentiation 70 to treat various solid tumors and hematologic malignancies. In addition, the company develops VCTX210, a gene-edited immune-evasive stem cell-derived product candidate for the treatment of treatment of type 1 diabetes; and pursues various in vivo gene-editing programs that target the liver, lung, muscle, and central nervous system diseases.
CRSP (CRISPR Therapeutics AG) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $5.09B, a beta of 1.74 versus the broader market, a 52-week range of 34.87-78.48, average daily share volume of 1.9M, a public-listing history dating back to 2016, approximately 393 full-time employees. These structural characteristics shape how CRSP stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on CRSP?
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 CRSP snapshot
As of May 15, 2026, spot at $48.77, ATM IV 53.87%, IV rank 12.78%, expected move 15.45%. The butterfly on CRSP 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 butterfly structure on CRSP specifically: CRSP IV at 53.87% is on the cheap side of its 1-year range, which favors premium-buying structures like a CRSP butterfly, with a market-implied 1-standard-deviation move of approximately 15.45% (roughly $7.53 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 CRSP expiries trade a higher absolute premium for lower per-day decay. Position sizing on CRSP should anchor to the underlying notional of $48.77 per share and to the trader's directional view on CRSP stock.
CRSP butterfly setup
The CRSP 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 CRSP near $48.77, the first option leg uses a $46.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CRSP 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 CRSP shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $46.00 | $4.55 |
| Sell 2 | Call | $49.00 | $2.70 |
| Buy 1 | Call | $51.00 | $1.88 |

When traders use butterfly on CRSP
Butterflies on CRSP are pinning bets - traders use them when they expect CRSP 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.
CRSP thesis for this butterfly
The market-implied 1-standard-deviation range for CRSP extends from approximately $41.24 on the downside to $56.30 on the upside. A CRSP long call butterfly is a pinning play: it pays maximum at the middle strike if CRSP settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CRSP IV rank near 12.78% 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 CRSP at 53.87%. As a Healthcare name, CRSP options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CRSP-specific events.
CRSP 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. CRSP positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CRSP alongside the broader basket even when CRSP-specific fundamentals are unchanged. Always rebuild the position from current CRSP chain quotes before placing a trade.
