What is a butterfly on CLNN?
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.
CLNN snapshot
As of August 14, 2026, spot at $4.21, ATM IV 22.70%, IV rank 1.53%, expected move 6.51%. The butterfly on CLNN 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 butterfly structure on CLNN specifically: CLNN IV at 22.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a CLNN butterfly, with a market-implied 1-standard-deviation move of approximately 6.51% (roughly $0.27 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 CLNN expiries trade a higher absolute premium for lower per-day decay. Position sizing on CLNN should anchor to the underlying notional of $4.21 per share and to the trader's directional view on CLNN stock.
CLNN butterfly setup
The CLNN 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 CLNN at $4.21 on that close, the first option leg uses a $4.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CLNN 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 CLNN shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $4.00 | N/A |
| Sell 2 | Call | $4.21 | N/A |
| Buy 1 | Call | $4.42 | N/A |

When traders use butterfly on CLNN
Butterflies on CLNN are pinning bets - traders use them when they expect CLNN 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.
CLNN thesis for this butterfly
The market-implied 1-standard-deviation range for CLNN extends from approximately $3.94 on the downside to $4.48 on the upside. A CLNN long call butterfly is a pinning play: it pays maximum at the middle strike if CLNN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CLNN IV rank near 1.53% 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 CLNN at 22.70%. As a Healthcare name, CLNN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CLNN-specific events.
CLNN 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. CLNN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CLNN alongside the broader basket even when CLNN-specific fundamentals are unchanged. Always rebuild the position from current CLNN chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on CLNN?
- A butterfly on CLNN is the butterfly strategy applied to CLNN (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 CLNN stock at $4.21 on the most recent close, the strikes shown on this page are snapped to the nearest listed CLNN chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are CLNN 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 CLNN butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 22.70%), 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 CLNN butterfly?
- The breakeven for the CLNN butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The CLNN market-implied 1-standard-deviation expected move in the same options snapshot is approximately 6.51%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
