Vanguard Total World Stock Index ETF(AMEX:VT)

The fund is passively managed to hold a well-diversified, market cap-weighted portfolio of developed and emerging market stocks. The fund ignores frontier markets as do most peer funds but excluding the likes of Vietnam and Kuwait has minimal impact on the fund's ability to track the global market. The funds inclusion of small-caps makes it incrementally more representative than direct rivals like ACWI. The fund uses a sampling approach to track its index - in that it may not hold all the stocks in the index - it will hold a representative sample of the securities that resembles the full index in terms of key risk factors.
