Picture this: After a long talk with your financial advisor, s/he leans back and says, “I think you should put 90% of your money into stocks and 10% into short-term government bonds.”
Your jaw drops, “What?”
Who could blame you? But, according to an excellent recent article by Craig L. Israelsen, those were Warren Buffet’s 2013 letter to Berkshire Hathaway shareholders disclosing his instructions to a trustee for the management of the final bequest to his wife.
Retire with all your money in only two asset classes? I wonder how that would sound to the regulators if an advisor made that recommendation to clients?
Dr. Israelson decided to test this concept using a $1 million retirement portfolio with annual withdrawals determined by the required minimum distribution (RMD) over a 25-year period – and he tested four different portfolios: (1) A seven-asset portfolio, (2) 60% large-cap US stocks and 40% aggregate bonds, (3) 90% large-cap US stocks and 10% short-term government bonds, and (4) 100% cash. His time frame was the 49-year period from 1970 to 2018, which contained 25 rolling 25-year periods.
Guess what? Buffett’s portfolio won! While all portfolios were solvent after 25 years, the Buffett model had the highest average ending balance after 25 years of withdrawals. It also provided the highest average annual withdrawal and the highest average of total withdrawals over 25 years.
The operative word, however, is average. The Buffett model also had the widest swings of all the other portfolios; but, when you have more than a billion dollars, who cares?
Most of us living in the real world of making our money last may love the destination; but, we may not like the ride.
