What is a butterfly on CALC?

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 CALC snapshot

As of May 15, 2026, spot at $0.67, ATM IV 199.10%, expected move 57.08%. The butterfly on CALC 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 63-day expiry.

Why this butterfly structure on CALC specifically: IV rank is unavailable in the current snapshot, so regime-based timing for CALC is inferred from ATM IV at 199.10% alone, with a market-implied 1-standard-deviation move of approximately 57.08% (roughly $0.38 on the underlying). The 63-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CALC expiries trade a higher absolute premium for lower per-day decay. Position sizing on CALC should anchor to the underlying notional of $0.67 per share and to the trader's directional view on CALC stock.

CALC butterfly setup

The CALC 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 CALC near $0.67, the first option leg uses a $0.64 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CALC chain at a 63-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 CALC shares for the stock leg in covered calls and collars).

When traders use butterfly on CALC

Butterflies on CALC are pinning bets - traders use them when they expect CALC 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.

CALC thesis for this butterfly

The market-implied 1-standard-deviation range for CALC extends from approximately $0.29 on the downside to $1.05 on the upside. A CALC long call butterfly is a pinning play: it pays maximum at the middle strike if CALC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Healthcare name, CALC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CALC-specific events.

CALC 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. CALC positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CALC alongside the broader basket even when CALC-specific fundamentals are unchanged. Always rebuild the position from current CALC chain quotes before placing a trade.

Frequently asked questions

What is a butterfly on CALC?
A butterfly on CALC is the butterfly strategy applied to CALC (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 CALC stock trading near $0.67, the strikes shown on this page are snapped to the nearest listed CALC chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
How are CALC 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 CALC butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 199.10%), 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 CALC butterfly?
The breakeven for the CALC 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 CALC market-implied 1-standard-deviation expected move is approximately 57.08%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
