What is a butterfly on PTCT?

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.

PTCT snapshot

As of August 14, 2026, spot at $71.93, ATM IV 49.70%, IV rank 16.44%, expected move 14.25%. The butterfly on PTCT below is built from the August 14, 2026 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 PTCT specifically: PTCT IV at 49.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a PTCT butterfly, with a market-implied 1-standard-deviation move of approximately 14.25% (roughly $10.25 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 PTCT expiries trade a higher absolute premium for lower per-day decay. Position sizing on PTCT should anchor to the underlying notional of $71.93 per share and to the trader's directional view on PTCT stock.

PTCT butterfly setup

The PTCT butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PTCT at $71.93 on that close, the first option leg uses a $70.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PTCT 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 PTCT shares for the stock leg in covered calls and collars).

When traders use butterfly on PTCT

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

PTCT thesis for this butterfly

The market-implied 1-standard-deviation range for PTCT extends from approximately $61.68 on the downside to $82.18 on the upside. A PTCT long call butterfly is a pinning play: it pays maximum at the middle strike if PTCT settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current PTCT IV rank near 16.44% 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 PTCT at 49.70%. As a Healthcare name, PTCT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PTCT-specific events.

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