Mac All World -
If you are an American investor, buying ACWI actually increases your exposure to the US dollar and US mega-caps. You are not diversifying away from the US; you are simply adding a small hedge of foreign stocks. For a US resident, ACWI is less diversified than a dedicated "World ex-US" fund.
Because so much passive money tracks the ACWI, when MSCI decides to upgrade a country from "Emerging" to "Developed" (e.g., South Korea or Taiwan), billions of dollars are forced to buy those stocks instantly, regardless of valuation. This creates artificial price inflation.
