VTIAX is a mutual fund offered by Vanguard that gives investors exposure to stocks outside the United States, including both developed and emerging markets around the world.
In simple terms: if you already invest in U.S. funds like VTSAX or VFIAX, then VTIAX is the international side of the portfolio.

It includes thousands of stocks, making it one of the most diversified international funds available.
From recent data, it holds 8,000+ companies across developed and emerging markets combined (StockAnalysis).
How VTIAX Works
This fund uses a passive index strategy, meaning:
It does not try to pick winning stocks

The “Global Portfolio” Strategy
Many investors combine VTIAX with U.S. funds to build a simple system:

International stocks → VTIAX
Bonds → bond index fund
This creates a globally diversified portfolio that doesn’t rely on one country’s economy.
Final Thoughts
