How are PTCT straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the PTCT straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 52.00%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$2,701.09 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a PTCT straddle?

The breakeven for the PTCT straddle priced on this page is roughly $52.70 and $107.30 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 PTCT market-implied 1-standard-deviation expected move is approximately 14.91%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current PTCT implied volatility affect this straddle?

PTCT ATM IV is at 52.00% with IV rank near 23.19%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

Current PTCT snapshot

As of June 30, 2026, spot at $81.76, ATM IV 52.00%, IV rank 23.19%, expected move 14.91%. The straddle on PTCT 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 199-day expiry.

Why this straddle structure on PTCT specifically: PTCT IV at 52.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a PTCT straddle, with a market-implied 1-standard-deviation move of approximately 14.91% (roughly $12.19 on the underlying). The 199-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 $81.76 per share and to the trader's directional view on PTCT stock.

PTCT straddle setup

The PTCT straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PTCT near $81.76, the first option leg uses a $80.00 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 199-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).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$80.00	$16.00
Buy 1	Put	$80.00	$11.30

When traders use straddle on PTCT

Straddles on PTCT are pure-volatility plays that profit from large moves in either direction; traders typically buy PTCT straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

PTCT thesis for this straddle

The market-implied 1-standard-deviation range for PTCT extends from approximately $69.57 on the downside to $93.95 on the upside. A PTCT long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current PTCT IV rank near 23.19% 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 52.00%. 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 straddle positions are structurally neutral / high-volatility (long premium); 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.
