Current EFX snapshot

As of June 30, 2026, spot at $158.07, ATM IV 40.70%, IV rank 56.58%, expected move 11.67%. The long put on EFX 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 long put structure on EFX specifically: EFX IV at 40.70% 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 11.67% (roughly $18.44 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 EFX expiries trade a higher absolute premium for lower per-day decay. Position sizing on EFX should anchor to the underlying notional of $158.07 per share and to the trader's directional view on EFX stock.

EFX long put setup

The EFX 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 EFX near $158.07, the first option leg uses a $160.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EFX 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 EFX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$160.00	$6.55

When traders use long put on EFX

Long puts on EFX hedge an existing long EFX stock position or express a bearish view with defined risk; position sizing typically scales the put notional to the underlying EFX exposure being hedged.

EFX thesis for this long put

The market-implied 1-standard-deviation range for EFX extends from approximately $139.63 on the downside to $176.51 on the upside. A EFX long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long EFX position with one put per 100 shares held. Current EFX IV rank near 56.58% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on EFX should anchor more to the directional view and the expected-move geometry. As a Industrials name, EFX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EFX-specific events.

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