An All-World ETF is a fund that invests in companies from both developed and emerging markets around the world.

It provides broad global diversification through a single investment product, making it popular among long-term investors.

Many All-World ETFs track global stock market indexes and contain thousands of companies across multiple countries and industries.

Because of their diversification and simplicity, All-World ETFs are often considered a core building block of a long-term investment portfolio.
