ACWIBiShares MSCI ACWI ETF

IOOBiShares Global 100 ETF

In short

ACWI ACWI borrows its name from the benchmark pros use as shorthand for "global stocks": large and mid caps across developed and emerging markets, roughly 2,200 of them, bought in one trade.

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.

Stated mandate

ACWI The fund seeks to track an index of large- and mid-cap equities across developed and emerging markets worldwide.

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

Why people hold it

  • ACWI One ticker, both halves of the world map: developed and emerging markets, large and mid caps, roughly 2,200 stocks in a single line item.
  • Charges 0.32% a year, below the 0.45% median for its index-tracking peer group.
  • Trading since 2008 and now a multi-billion-dollar fund that changes hands actively, which shows up in tight, dependable execution.
  • Sticks close to the MSCI All Country World Index it quotes, one of the stronger index implementations in its peer group.
  • 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.

Worth knowing

  • ACWI Fee is the trade-off: VT runs the same one-ticker global idea at 0.06%.
  • The mandate stops at large and mid caps, so the world's smaller companies sit outside the portfolio.
  • Emerging-market holdings and foreign currencies come with the package, so returns move with more than just US stocks.
  • 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.
