Warren Buffett's 90/10 Portfolio

Last updated Apr 1, 2023

This portfolio follows the guidelines that Warren Buffett has written in his will for his wife's trust in the 2013 letter to Berkshire Hathaway shareholders. They state that the trustee should invest 90% in a low-cost S&P 500 index fund, with the remaining 10% invested in a short-term government bonds fund. The basic strategy is to own a major slice of all American businesses that are bound to grow in total. Buffett believes this portfolio is "superior to those attained by most investors - whether pension funds, institutions or individuals."
