What is a butterfly on CHRS?
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 CHRS snapshot
As of May 15, 2026, spot at $1.58, ATM IV 131.90%, IV rank 27.94%, expected move 37.81%. The butterfly on CHRS 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 CHRS specifically: CHRS IV at 131.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a CHRS butterfly, with a market-implied 1-standard-deviation move of approximately 37.81% (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 CHRS expiries trade a higher absolute premium for lower per-day decay. Position sizing on CHRS should anchor to the underlying notional of $1.58 per share and to the trader's directional view on CHRS stock.
CHRS butterfly setup
The CHRS 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 CHRS near $1.58, the first option leg uses a $1.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CHRS 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 CHRS shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $1.50 | N/A |
| Sell 2 | Call | $1.58 | N/A |
| Buy 1 | Call | $1.66 | N/A |
CHRS 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 CHRS
Butterflies on CHRS are pinning bets - traders use them when they expect CHRS 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.
CHRS thesis for this butterfly
The market-implied 1-standard-deviation range for CHRS extends from approximately $0.98 on the downside to $2.18 on the upside. A CHRS long call butterfly is a pinning play: it pays maximum at the middle strike if CHRS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CHRS IV rank near 27.94% 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 CHRS at 131.90%. As a Healthcare name, CHRS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CHRS-specific events.
CHRS 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. CHRS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CHRS alongside the broader basket even when CHRS-specific fundamentals are unchanged. Always rebuild the position from current CHRS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on CHRS?
- A butterfly on CHRS is the butterfly strategy applied to CHRS (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 CHRS stock trading near $1.58, the strikes shown on this page are snapped to the nearest listed CHRS chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are CHRS 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 CHRS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 131.90%), 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 CHRS butterfly?
- The breakeven for the CHRS 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 CHRS market-implied 1-standard-deviation expected move is approximately 37.81%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on CHRS?
- Butterflies on CHRS are pinning bets - traders use them when they expect CHRS 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 CHRS implied volatility affect this butterfly?
- CHRS ATM IV is at 131.90% with IV rank near 27.94%, 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.
