Current PTGX snapshot

As of May 15, 2026, spot at $102.63, ATM IV 39.10%, IV rank 3.70%, expected move 11.21%. The iron condor on PTGX 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 34-day expiry.

Why this iron condor structure on PTGX specifically: PTGX IV at 39.10% is on the cheap side of its 1-year range, which means a premium-selling PTGX iron condor collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 11.21% (roughly $11.50 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PTGX expiries trade a higher absolute premium for lower per-day decay. Position sizing on PTGX should anchor to the underlying notional of $102.63 per share and to the trader's directional view on PTGX stock.

PTGX iron condor setup

The PTGX iron condor below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PTGX near $102.63, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PTGX chain at a 34-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 PTGX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Sell 1	Call	$110.00	$1.93
Buy 1	Call	$115.00	$1.10
Sell 1	Put	$95.00	$1.48
Buy 1	Put	$90.00	$2.48

PTGX thesis for this iron condor

The market-implied 1-standard-deviation range for PTGX extends from approximately $91.13 on the downside to $114.13 on the upside. A PTGX iron condor is a delta-neutral premium-collection structure that pays off when PTGX stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current PTGX IV rank near 3.70% 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 PTGX at 39.10%. As a Healthcare name, PTGX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PTGX-specific events.

PTGX iron condor positions are structurally neutral / range-bound; 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. PTGX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PTGX alongside the broader basket even when PTGX-specific fundamentals are unchanged. Short-premium structures like a iron condor on PTGX carry tail risk when realized volatility exceeds the implied move; review historical PTGX earnings reactions and macro stress periods before sizing. Always rebuild the position from current PTGX chain quotes before placing a trade.
