Current PNR snapshot

As of June 29, 2026, spot at $76.15, ATM IV 37.70%, IV rank 83.23%, expected move 10.81%. The bear put spread on PNR 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 bear put spread structure on PNR specifically: PNR IV at 37.70% is rich versus its 1-year range, which makes a premium-buying PNR bear put spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 10.81% (roughly $8.23 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 PNR expiries trade a higher absolute premium for lower per-day decay. Position sizing on PNR should anchor to the underlying notional of $76.15 per share and to the trader's directional view on PNR stock.

PNR bear put spread setup

The PNR bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PNR near $76.15, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PNR 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 PNR shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$75.00	$1.30

PNR thesis for this bear put spread

A PNR bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on PNR, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current PNR IV rank near 83.23% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on PNR at 37.70%. As a Industrials name, PNR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PNR-specific events.

PNR bear put spread positions are structurally moderately bearish; 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. PNR positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PNR alongside the broader basket even when PNR-specific fundamentals are unchanged. Long-premium structures like a bear put spread on PNR are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome.
