VSTM Covered Call 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 $578.2M, a beta of 0.29 versus the broader market, a 52-week range of 3.43-11.25, average daily share volume of 2.4M, 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 covered call on VSTM?

VSTM snapshot

As of August 14, 2026, spot at $6.58, ATM IV 87.40%, IV rank 15.75%, expected move 25.06%. The covered call 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 covered call structure on VSTM specifically: VSTM IV at 87.40% is on the cheap side of its 1-year range, which means a premium-selling VSTM covered call collects less credit per unit of strike-width risk, 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 covered call setup

The VSTM covered call 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 $6.91 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).

When traders use covered call on VSTM

Covered calls on VSTM are an income strategy run on existing VSTM stock positions; traders typically sell calls at 25-35 delta with 30-45 days to expiration to balance premium against upside cap.

VSTM thesis for this covered call

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 covered call collects premium on an existing long VSTM position, trading off upside above the short call strike for immediate income; the short strike selection should reflect the trader's view on whether VSTM will breach that level within the expiration window. 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 covered call positions are structurally neutral to slightly bullish; 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. Short-premium structures like a covered call on VSTM carry tail risk when realized volatility exceeds the implied move; review historical VSTM earnings reactions and macro stress periods before sizing. Always rebuild the position from current VSTM chain quotes before placing a trade.
