Stock ETFs
The first and most popular ETFs track stocks. Many funds track national indexes; for example, Vanguard Total Stock Market ETF NYSE: VTI tracks the MSCI US Broad Market Index, and several funds track the S&P 500, both indexes for US stocks. Other funds own stocks from many countries; for example, Vanguard Total International Stock Index NASDAQ: VXUS tracks the MSCI All Country World ex USA Investable Market Index, while the iShares MSCI EAFE Index NYSE: EFA tracks the MSCI EAFE Index, both "world ex-US" indexes.
