Our read on each fund

IOOBiShares Global 100 ETF

SPGMAState Street SPDR Portfolio MSCI Global Stock Market ETF

In short

IOO Global 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.

SPGM One ticker for the whole investable world. SPGM tracks MSCI's ACWI IMI index, holding roughly 2,900 stocks across developed and emerging markets, and charges 0.09% a year to do it.

Stated mandate

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

SPGM The fund seeks to track, before fees and expenses, the total return performance of the MSCI ACWI IMI Index.

Why people hold it

  • IOO Launched in 2000, one of the original global blue-chip index funds, and a multi-billion-dollar fund today.
  • Straight indexing, no manager discretion. It has tracked the S&P Global 100 very closely.ishares.com
  • At 0.40%, it runs a touch under the typical index wrapper in its peer group.
  • One ticket for global large-cap equity instead of bolting a US fund to an international one.
  • SPGM 0.09% a year, against a 0.45% median for the index-wrapper funds it competes with. That gap compounds quietly in your favor.
  • Roughly 2,900 stocks in one line item: US, developed foreign, emerging. No rebalancing between three regional funds, no home-country blind spot.ssga.com
  • Pure replication, done tightly: the fund has stuck close to the MSCI ACWI IMI index it promises, one of the cleaner implementations among the index trackers we cover.ssga.com
  • Live since 2012 and now a multi-billion-dollar fund, so it is not a launch-year experiment hunting for assets.

Worth knowing

  • IOO About 100 names, so a handful of mega-caps do the heavy lifting. Broad wrappers like VT own thousands.
  • 0.40% is real money beside the broad-index cheapies: VT at 0.06%, SCHK at 0.03%.
  • Income lands once or twice a year, not monthly, and volume is moderate rather than heavy.
  • SPGM Vanguard's VT covers similar all-world ground for 0.06%. Small gap, but real if fee is your only tiebreaker.
  • Owning the world means owning its currencies and its emerging markets. Foreign swings show up in your return, unsmoothed.
  • Moderately traded rather than a volume monster, so bid-ask spreads can run wider than the busiest global funds.
