What is a long put on STN?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
Current STN snapshot
As of May 15, 2026, spot at $77.02, ATM IV 34.90%, IV rank 4.68%, expected move 10.01%. The long put on STN 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 long put structure on STN specifically: STN IV at 34.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a STN long put, with a market-implied 1-standard-deviation move of approximately 10.01% (roughly $7.71 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 STN expiries trade a higher absolute premium for lower per-day decay. Position sizing on STN should anchor to the underlying notional of $77.02 per share and to the trader's directional view on STN stock.
STN long put setup
The STN long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With STN near $77.02, the first option leg uses a $77.02 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STN 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 STN shares for the stock leg in covered calls and collars).

STN thesis for this long put
The market-implied 1-standard-deviation range for STN extends from approximately $69.31 on the downside to $84.73 on the upside. A STN long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long STN position with one put per 100 shares held. Current STN IV rank near 4.68% 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 STN at 34.90%. As a Industrials name, STN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STN-specific events.
STN long put positions are structurally 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. STN positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STN alongside the broader basket even when STN-specific fundamentals are unchanged. Long-premium structures like a long put on STN 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. Always rebuild the position from current STN chain quotes before placing a trade.
