What is a long put on IOSP?

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.

IOSP snapshot

As of August 14, 2026, spot at $93.98, ATM IV 31.10%, IV rank 4.06%, expected move 8.92%. The long put on IOSP below is built from the 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 long put structure on IOSP specifically: IOSP IV at 31.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a IOSP long put, with a market-implied 1-standard-deviation move of approximately 8.92% (roughly $8.38 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 IOSP expiries trade a higher absolute premium for lower per-day decay. Position sizing on IOSP should anchor to the underlying notional of $93.98 per share and to the trader's directional view on IOSP stock.

IOSP long put setup

The IOSP 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 IOSP at $93.98 on that close, the first option leg uses a $93.98 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IOSP 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 IOSP shares for the stock leg in covered calls and collars).

IOSP thesis for this long put

The market-implied 1-standard-deviation range for IOSP extends from approximately $85.60 on the downside to $102.36 on the upside. A IOSP long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long IOSP position with one put per 100 shares held. Current IOSP IV rank near 4.06% 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 IOSP at 31.10%. As a Basic Materials name, IOSP options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IOSP-specific events.

IOSP 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. IOSP positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IOSP alongside the broader basket even when IOSP-specific fundamentals are unchanged. Long-premium structures like a long put on IOSP 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 IOSP chain quotes before placing a trade.
