IOO - iShares Global 100 ETF

IOO seeks to deliver cap-weighted exposure to 100 of the world's largest multinational companies from its parent index, the S&P Global 1200, and lands squarely in the mega-cap rather than the large-cap domain. The fund avoids midcaps altogether. Its focus on mega-caps, and its avoidance of emerging markets outside Korea, introduces some sector and geographic tilts.

As of Jun 30, 2026: spot at $136.54, ATM IV 374.9%, max pain $115.00, net GEX -$2.0K.

What IOO Looks Like to Options Traders Today

IV rank of 74.6% signals elevated pricing relative to the 1-year history, conditions that typically favor premium-selling structures (credit spreads, iron condors, covered calls); negative net gamma exposure (-$2.0K) means dealers hedge with trend, amplifying realized volatility and accelerating directional moves; the 25-delta skew (0.012) is roughly flat across the wings.
