The Three-Fund Portfolio

Once you know your stock-vs-bond split, you need actual funds to fill it. The simplest portfolio that professional investors genuinely respect is the 'three-fund portfolio,' popularized by the Bogleheads community: one fund for US stocks, one for international stocks, and one for bonds. Three funds, a small amount of money, and you own a slice of essentially every public company on earth plus a bond cushion.

A common starting mix by age: a 25-year-old might hold roughly 60% VTI / 30% VXUS / 10% BND; a 45-year-old 50 / 25 / 25; a 65-year-old 35 / 15 / 50 -- more bonds as the horizon shortens. These are starting points, not gospel: the bond slice is really a function of your time horizon and how well you sleep during a crash.

§ 03
In the **Portfolio** view, model a simple three-fund mix -- say 60% VTI, 30% VXUS, 10% BND -- and look at the blended picture. You now hold thousands of companies across just three holdings.
§ 04

The three-fund portfolio wins not because it is clever but because it is cheap, diversified, and boring enough to leave alone. William Bernstein's free pamphlet 'If You Can' argues that a young saver who simply buys these three funds and ignores the noise will beat most professionals over a lifetime.
