VSTM Butterfly Strategy
VSTM (Verastem, Inc.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
Verastem, Inc. is an emerging biopharmaceutical company dedicated to the creation and commercialization of innovative therapeutic agents for cancer treatment. A primary asset in its pipeline is VS-6766, a novel dual RAF/MEK inhibitor that operates by a "clamp" mechanism. This unique action effectively blocks the kinase activity of MEK and disrupts RAF's ability to phosphorylate MEK. The company is actively advancing several clinical trials. RAMP 201 is an adaptive, two-part, multicenter, randomized, open-label study designed to assess both the efficacy and safety of VS-6766, administered alone or in combination with defactinib. Defactinib is an oral small molecule inhibitor of focal adhesion kinase (FAK), and this trial targets patients with recurrent low-grade serous ovarian cancer.
VSTM (Verastem, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $610.7M, a beta of 0.29 versus the broader market, a 52-week range of 3.43-11.25, average daily share volume of 2.5M, a public-listing history dating back to 2012, approximately 102 full-time employees. These structural characteristics shape how VSTM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.29 indicates VSTM has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure.
What is a butterfly on VSTM?
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.
VSTM snapshot
As of August 14, 2026, spot at $6.58, ATM IV 87.40%, IV rank 15.75%, expected move 25.06%. The butterfly on VSTM below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on VSTM specifically: VSTM IV at 87.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a VSTM butterfly, with a market-implied 1-standard-deviation move of approximately 25.06% (roughly $1.65 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated VSTM expiries trade a higher absolute premium for lower per-day decay. Position sizing on VSTM should anchor to the underlying notional of $6.58 per share and to the trader's directional view on VSTM stock.
VSTM butterfly setup
The VSTM 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 VSTM at $6.58 on that close, the first option leg uses a $6.25 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed VSTM chain at a 35-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 VSTM shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $6.25 | N/A |
| Sell 2 | Call | $6.58 | N/A |
| Buy 1 | Call | $6.91 | N/A |
VSTM butterfly risk and reward
- Net Premium / Debit
- N/A
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)
- Unbounded
- Breakeven(s)
- None on modeled curve
- Risk / Reward Ratio
- N/A
Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit.

When traders use butterfly on VSTM
Butterflies on VSTM are pinning bets - traders use them when they expect VSTM 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.
VSTM thesis for this butterfly
The market-implied 1-standard-deviation range for VSTM extends from approximately $4.93 on the downside to $8.23 on the upside. A VSTM long call butterfly is a pinning play: it pays maximum at the middle strike if VSTM settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current VSTM IV rank near 15.75% 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 VSTM at 87.40%. As a Healthcare name, VSTM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to VSTM-specific events.
VSTM 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. VSTM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move VSTM alongside the broader basket even when VSTM-specific fundamentals are unchanged. Always rebuild the position from current VSTM chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on VSTM?
- A butterfly on VSTM is the butterfly strategy applied to VSTM (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With VSTM stock at $6.58 on the most recent close, the strikes shown on this page are snapped to the nearest listed VSTM chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are VSTM butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the VSTM butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 87.40%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a VSTM butterfly?
- The breakeven for the VSTM butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The VSTM market-implied 1-standard-deviation expected move in the same options snapshot is approximately 25.06%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on VSTM?
- Butterflies on VSTM are pinning bets - traders use them when they expect VSTM 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.
- How does current VSTM implied volatility affect this butterfly?
- VSTM ATM IV is at 87.40% with IV rank near 15.75%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
