Over the years there have been a number of highly contested battles — Coke vs. Pepsi, Lakers vs. Celtics, Ali vs. Frazier. In the world of investing, there\u2019s also heated rivalry: active vs. passive. Recently passive investing has gotten some extra muscle thanks to its newest champion: billionaire investor Warren Buffett.<\/p>\n

A decade ago Buffett, chairman and CEO of $517 billion Berkshire Hathaway, famously wagered $1 million that the S&P 500 stock index would outperform hedge funds, which he described in a 2016 letter to Berkshire Hathaway shareholders<\/a>. Buffet\u2019s claim was that over the span of ten years active investment management by professionals would actually underperform the returns by amateurs who were passively investing with index funds, after fees, costs and expenses.<\/p>\n

But only one person took the bet: Ted Seides, a former co-manager of Prot\u00e9g\u00e9 Partners, a specialized asset management and advisory firm. The wager was made and the tortoise and the hare battle began: Buffett\u2019s low-cost Vanguard index fund returns vs. Seides\u2019 group of handpicked Prot\u00e9g\u00e9 hedge funds.<\/p>\n

The result? With a few months left to go in 2017, Seides has conceded. That\u2019s because he was getting smoked by Buffett\u2019s passive strategy. Seides\u2019 five funds-of-funds gained 2.2% on a compounded annual basis in the nine years through 2016, versus 7% for the S&P 500. According to Buffett, $1 million invested in those hedge funds would have gained $220,000. Meanwhile, the Vanguard index fund would have gained $854,000. (The good news: all proceeds of this wager are going to charity).<\/p>\n

For regular readers of our blog a lot of the message of this story should sound very familiar: low-cost index funds on a long-term basis are the key to\u00a0 getting the most return for your risk budget. However, for many the passive position Buffett took came as a surprise.<\/p>\n

The 90\/10 Challenge<\/h3>\n

But this wasn\u2019t the first time Warren Buffett was contrarian. In his 2013 Berkshire Hathaway annual report and shareholder letter<\/a> he caused quite a stir by revealing his \u201c90\/10\u201d plan for the assets he was bequeathing to his wife upon his demise. Buffett recommended that 90% of the cash would be put in a very-low cost S&P 500 index fund while the other 10% would be allocated to short-term government bonds. People were so shocked because — at that time — it felt like the ultimate contradiction: an endorsement of index investing from the man who was thought of as one of the greatest stock pickers of all time. It also probably left many people questioning the various portfolio allocations and ratios their own financial advisors had put them in.<\/p>\n

We had a different question: how does a diversified portfolio (similar to those offered by Wealthfront) compare with Buffett\u2019s 90\/10 investing strategy over time? What we found was that someone implementing Mr. Buffett\u2019s advice would have actually been better off investing in the diversified portfolio.<\/p>\n

To illustrate this point, let\u2019s compare the average risk-adjusted return from a hypothetical Buffett 90\/10 portfolio over the past 15 years (from July 1, 2002 to June 30, 2017) with what could have been expected from a well diversified portfolio over the same time period if it had existed. To evaluate the Buffett 90\/10 portfolio we calculated returns on a portfolio that is 90% allocated to the S&P 500 and 10% to short-term U.S. Treasury securities. To represent the diversified portfolio we created a hypothetical portfolio with an asset allocation similar to what one would find in a taxable risk level 7 portfolio employed by Wealthfront (risk level 7 is the average risk level for all Wealthfront clients). The diversified portfolio included allocations to municipal bonds, treasury inflation protected securities (TIPS), dividend growth stocks, U.S. stocks, foreign developed stocks, emerging markets stocks, and commodities. To calculate risk-adjusted returns we used the Sharpe Ratio, the industry standard metric for such comparisons. The Sharpe Ratio was first proposed by Bill Sharpe, the co-recipient of the 1990 Nobel Prize in economics for Modern Portfolio Theory.<\/p>\n

\"\"<\/p>\n

The more diversified portfolio had a higher average annual return and a much higher risk-adjusted return than Mr. Buffett\u2019s recommended portfolio. Why? Because the more diversified portfolio is diversified globally across seven asset classes, while Mr. Buffett\u2019s is composed almost entirely of U.S. equities. As we explain in our investment methodology white paper<\/a>, adding relatively uncorrelated asset classes to a portfolio almost always increases the return for a given level of risk. You begin to see radically diminishing returns when you attempt to broaden beyond seven asset classes. Mr. Buffett most likely suggested a very simple two-asset class portfolio because of its low fees and lack of familiarity with such new cost effective approaches as automated\u00a0investment services.<\/p>\n

Final Thoughts<\/h3>\n

To be fair, over the past 15 years the returns of Berkshire Hathaway have outperformed the average diversified portfolio. That said, Warren Buffett is a once-in-a-lifetime investor, which is probably why he recommended that his family choose index funds once he is gone, as well as his general belief that the average investor should opt for a diversified portfolio of index funds. And with his highly publicized \u201cvictory\u201d over Ted Seides, we\u2019re hopeful more people will come to appreciate the value of low-cost index funds and a passive investing mindset when it comes to long-term performance.<\/p>\n","protected":false},"excerpt":{"rendered":"
