Brazil Potash Corp. engages in the exploration and development of potash properties in Brazil. It holds interest in the Autazes Project located in the state of Amazonas, Brazil. The company was incorporated in 2006 and is based in Toronto, Canada.
GRO (Brazil Potash Corp.) trades in the Basic Materials sector, specifically Industrial Materials, with a market capitalization of approximately $117.5M, a beta of -0.35 versus the broader market, a 52-week range of 1.25-3.99, average daily share volume of 934K, a public-listing history dating back to 2024, approximately 36 full-time employees.

What is a butterfly on GRO?
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 GRO snapshot
As of May 15, 2026, spot at $2.65, ATM IV 79.40%, expected move 22.76%. The butterfly on GRO 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 GRO specifically: IV rank is unavailable in the current snapshot, so regime-based timing for GRO is inferred from ATM IV at 79.40% alone, with a market-implied 1-standard-deviation move of approximately 22.76% (roughly $0.60 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 GRO expiries trade a higher absolute premium for lower per-day decay. Position sizing on GRO should anchor to the underlying notional of $2.65 per share and to the trader's directional view on GRO stock.
GRO butterfly setup
The GRO 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 GRO near $2.65, the first option leg uses a $2.52 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GRO 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 GRO shares for the stock leg in covered calls and collars).

GRO thesis for this butterfly
The market-implied 1-standard-deviation range for GRO extends from approximately $2.05 on the downside to $3.25 on the upside. A GRO long call butterfly is a pinning play: it pays maximum at the middle strike if GRO settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Basic Materials name, GRO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GRO-specific events.
GRO 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. GRO positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GRO alongside the broader basket even when GRO-specific fundamentals are unchanged. Always rebuild the position from current GRO chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on GRO?
- A butterfly on GRO is the butterfly strategy applied to GRO (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 GRO stock trading near $2.65, the strikes shown on this page are snapped to the nearest listed GRO chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are GRO 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 GRO butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 79.40%), 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 GRO butterfly?
- The breakeven for the GRO 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 GRO market-implied 1-standard-deviation expected move is approximately 22.76%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
