How are VKTX 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 VKTX butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 57.57%), the computed maximum profit is $93.15 per contract and the computed maximum loss is -$103.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a VKTX butterfly?

The breakeven for the VKTX butterfly priced on this page is roughly $28.96 and $30.97 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 VKTX market-implied 1-standard-deviation expected move is approximately 16.50%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

Current VKTX snapshot

As of May 15, 2026, spot at $30.42, ATM IV 57.57%, IV rank 8.60%, expected move 16.50%. The butterfly on VKTX 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 28-day expiry.

Why this butterfly structure on VKTX specifically: VKTX IV at 57.57% is on the cheap side of its 1-year range, which favors premium-buying structures like a VKTX butterfly, with a market-implied 1-standard-deviation move of approximately 16.50% (roughly $5.02 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated VKTX expiries trade a higher absolute premium for lower per-day decay. Position sizing on VKTX should anchor to the underlying notional of $30.42 per share and to the trader's directional view on VKTX stock.

VKTX butterfly setup

The VKTX 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 VKTX near $30.42, the first option leg uses a $29.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed VKTX chain at a 28-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 VKTX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$29.00	$3.03
Sell 2	Call	$30.00	$2.15
Buy 1	Call	$32.00	$1.31

When traders use butterfly on VKTX

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

VKTX thesis for this butterfly

The market-implied 1-standard-deviation range for VKTX extends from approximately $25.40 on the downside to $35.44 on the upside. A VKTX long call butterfly is a pinning play: it pays maximum at the middle strike if VKTX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current VKTX IV rank near 8.60% 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 VKTX at 57.57%. As a Healthcare name, VKTX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to VKTX-specific events.

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