Global funds and trackers: owning the world in one fund
A global tracker buys a world share index, so one fund can hold anything from about 1,250 to 4,200 companies. At 30 September 2026 the United States made up 62.28% to 72.94% of the three main world indices, so a global fund is mostly a US and dollar fund.
