Our read on IOO

ETF.net Research

BGlobal investing boiled down to 100 mega-caps. Running since 2000, IOO tracks the S&P Global 100: blue chips that already sell on every continent, rather than the whole world's market.

Stated mandate

The Fund seeks to track the investment results of an index composed of 100 large-capitalization global equities.

Why people hold it

  1. 01Launched in 2000, one of the original global blue-chip index funds, and a multi-billion-dollar fund today.
  2. 02Straight indexing, no manager discretion. It has tracked the S&P Global 100 very closely.ishares.com
  3. 03At 0.40%, it runs a touch under the typical index wrapper in its peer group.
  4. 04One ticket for global large-cap equity instead of bolting a US fund to an international one.

Worth knowing

  1. 01About 100 names, so a handful of mega-caps do the heavy lifting. Broad wrappers like VT own thousands.
  2. 020.40% is real money beside the broad-index cheapies: VT at 0.06%, SCHK at 0.03%.
  3. 03Income lands once or twice a year, not monthly, and volume is moderate rather than heavy.
