What is a long put on CTOS?

Current CTOS snapshot

As of May 15, 2026, spot at $9.84, ATM IV 96.50%, IV rank 36.81%, expected move 27.67%. The long put on CTOS 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 CTOS specifically: CTOS IV at 96.50% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 27.67% (roughly $2.72 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 CTOS expiries trade a higher absolute premium for lower per-day decay. Position sizing on CTOS should anchor to the underlying notional of $9.84 per share and to the trader's directional view on CTOS stock.

CTOS long put setup

The CTOS 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 CTOS near $9.84, the first option leg uses a $9.84 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CTOS 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 CTOS shares for the stock leg in covered calls and collars).

CTOS thesis for this long put

The market-implied 1-standard-deviation range for CTOS extends from approximately $7.12 on the downside to $12.56 on the upside. A CTOS long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long CTOS position with one put per 100 shares held. Current CTOS IV rank near 36.81% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on CTOS should anchor more to the directional view and the expected-move geometry. As a Industrials name, CTOS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CTOS-specific events.

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