What is a butterfly on CTKB?
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 CTKB snapshot
As of June 30, 2026, spot at $4.36, ATM IV 25.80%, IV rank 4.79%, expected move 7.40%. The butterfly on CTKB 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 17-day expiry.
Why this butterfly structure on CTKB specifically: CTKB IV at 25.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a CTKB butterfly, with a market-implied 1-standard-deviation move of approximately 7.40% (roughly $0.32 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CTKB expiries trade a higher absolute premium for lower per-day decay. Position sizing on CTKB should anchor to the underlying notional of $4.36 per share and to the trader's directional view on CTKB stock.
CTKB butterfly setup
The CTKB 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 CTKB near $4.36, the first option leg uses a $4.14 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CTKB chain at a 17-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 CTKB shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $4.14 | N/A |
| Sell 2 | Call | $4.36 | N/A |
| Buy 1 | Call | $4.58 | N/A |

When traders use butterfly on CTKB
Butterflies on CTKB are pinning bets - traders use them when they expect CTKB 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.
CTKB thesis for this butterfly
The market-implied 1-standard-deviation range for CTKB extends from approximately $4.04 on the downside to $4.68 on the upside. A CTKB long call butterfly is a pinning play: it pays maximum at the middle strike if CTKB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CTKB IV rank near 4.79% 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 CTKB at 25.80%. As a Healthcare name, CTKB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CTKB-specific events.
CTKB 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. CTKB positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CTKB alongside the broader basket even when CTKB-specific fundamentals are unchanged. Always rebuild the position from current CTKB chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on CTKB?
- A butterfly on CTKB is the butterfly strategy applied to CTKB (stock).

With CTKB stock trading near $4.36, the strikes shown on this page are snapped to the nearest listed CTKB chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are CTKB 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 CTKB butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 25.80%), 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 CTKB butterfly?
- The breakeven for the CTKB 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 CTKB market-implied 1-standard-deviation expected move is approximately 7.40%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
