VT is the simplest possible approach to global equity investing: one fund that owns approximately 9,500 stocks across all countries weighted by market capitalization, covering the US (~60%), international developed markets (~30%) and emerging markets (~10%). It is the one-fund equity portfolio that finance textbooks describe when explaining global diversification — if you own VT, you own proportional shares of virtually every publicly traded company in the world. The US dominance in the fund reflects the current US market capitalization relative to global markets; this weighting adjusts automatically as relative market values shift. The 0.06% expense ratio is remarkably low for global coverage. Currency risk is unhedged — VT includes non-US equity exposure that fluctuates with global currency movements against the dollar. For investors who want to outsource the asset allocation decision about US versus international weighting to the market itself, VT is the perfect solution — you get whatever the market says is the appropriate weighting at any given time. It is particularly appropriate for investors who lack the conviction to make specific US/international allocation decisions or who simply want the most diversified possible equity exposure in a single fund.
