What is Warren Buffett’s 90/10 rule?
Warren Buffett’s #1 money tip for retirees is a method that allocates 90% of investment capital into stock-based index funds while the remaining 10% of money is put into lower-risk investments. Buffett’s favorite exchange traded index fund is one that tracks the S&P 500 like the SPDR SPY ETF or Vanguard’s VOO. He has seen that the S&P 500 beats the majority of all mutual fund managers and that the ETFs also save investors a lot of money with much lower management fees that add up over time.
In a letter to Berkshire Hathaway shareholders, Warren Buffett outlined his investing plan to use the 90/10 rule regarding his wife’s inheritance, which will be invested 90% in an S&P 500 index fund and 10% in government bonds. 
This keeps 90% of retirees capital growing by tracking the increase in prices of 500 of the best U.S. companies and also keeping 10% of capital safely in short term bonds to be spent on living expenses.
The S&P 500 index is a very diversified by sector for a smoother equity curve.
