Current IOO snapshot

As of June 30, 2026, spot at $136.54, ATM IV 374.90%, IV rank 74.64%, expected move 107.48%. The bear put spread on IOO 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 IOO specifically: IOO IV at 374.90% is rich versus its 1-year range, which makes a premium-buying IOO bear put spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 107.48% (roughly $146.75 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 IOO expiries trade a higher absolute premium for lower per-day decay. Position sizing on IOO should anchor to the underlying notional of $136.54 per share and to the trader's directional view on IOO etf.

IOO bear put spread setup

The IOO 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 IOO near $136.54, the first option leg uses a $135.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IOO 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 IOO shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$135.00	$1.21

As a Financial Services name, IOO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IOO-specific events.

IOO positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IOO alongside the broader basket even when IOO-specific fundamentals are unchanged. Long-premium structures like a bear put spread on IOO 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.
