GRCE (Grace Therapeutics, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $34.8M, a beta of 0.32 versus the broader market, a 52-week range of 1.79-5.18, average daily share volume of 785K, a public-listing history dating back to 2012, approximately 4 full-time employees. These structural characteristics shape how GRCE stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.32 indicates GRCE 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 GRCE?
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 GRCE snapshot
As of May 15, 2026, spot at $2.19, ATM IV 102.30%, expected move 29.33%. The butterfly on GRCE 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 GRCE specifically: IV rank is unavailable in the current snapshot, so regime-based timing for GRCE is inferred from ATM IV at 102.30% alone, with a market-implied 1-standard-deviation move of approximately 29.33% (roughly $0.64 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 GRCE expiries trade a higher absolute premium for lower per-day decay. Position sizing on GRCE should anchor to the underlying notional of $2.19 per share and to the trader's directional view on GRCE stock.
GRCE butterfly setup
The GRCE 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 GRCE near $2.19, the first option leg uses a $2.08 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GRCE 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 GRCE shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $2.08 | N/A |
| Sell 2 | Call | $2.19 | N/A |
| Buy 1 | Call | $2.30 | N/A |
GRCE butterfly risk and reward

- N/A
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)
- Unbounded

When traders use butterfly on GRCE
Butterflies on GRCE are pinning bets - traders use them when they expect GRCE 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.
GRCE thesis for this butterfly
The market-implied 1-standard-deviation range for GRCE extends from approximately $1.55 on the downside to $2.83 on the upside. A GRCE long call butterfly is a pinning play: it pays maximum at the middle strike if GRCE settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Healthcare name, GRCE options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GRCE-specific events.
GRCE 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. GRCE positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GRCE alongside the broader basket even when GRCE-specific fundamentals are unchanged. Always rebuild the position from current GRCE chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on GRCE?
- A butterfly on GRCE is the butterfly strategy applied to GRCE (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 GRCE stock trading near $2.19, the strikes shown on this page are snapped to the nearest listed GRCE chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are GRCE 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 GRCE butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 102.30%), 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 GRCE butterfly?
- The breakeven for the GRCE butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current GRCE market-implied 1-standard-deviation expected move is approximately 29.33%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on GRCE?
- Butterflies on GRCE are pinning bets - traders use them when they expect GRCE 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 GRCE implied volatility affect this butterfly?
- Current GRCE ATM IV is 102.30%; IV rank context is unavailable in the current snapshot.
