Thoughts on Warren Buffett’s 10-Year Bet: Active, Passive—or a Combination
By Robert Bacarella
I haven’t been in the investment business as long as Warren Buffett, but in over forty years of observing the industry I’ve seen a lot—and certainly enough that I’m not surprised Warren Buffett won his 10-year bet that a passive index would outperform a group of hand-selected active managers.
The bet is outlined in Warren Buffett’s most recent annual letter to Berkshire Hathaway shareholders. In a nutshell, Buffett and a fund of hedge funds called Protégé Partners entered a charitable wager about whether a selection of five funds-of-funds would outperform the S&P 500 Index over 10 years. (For details, Read the full letter here. .)
- As Warren Buffett put it in his letter, “the five funds-of-funds got off to a fast start, each beating the index in 2008. Then the roof fell in. In every one of the nine years that followed, the funds-of-funds as a whole trailed the index.”
- Over the 10-year period, the S&P 500 logged an 8.5% average annual gain. The five funds-of-funds registered annual gains of 2.0%, 3.6%, 6.5%, 0.3% and 2.4%, according to the letter. Warren Buffett won the bet in dramatic fashion.
Put in context, this tremendous disparity isn’t as surprising at it might seem. Consider that, on average, 82% of actively managed U.S. funds have underperformed their benchmarks over the past 15 years. Even worse, large-cap growth managers underperformed 95% of the time.
Those are stark numbers, and they—and the result of Warren Buffett’s 10-year bet—might push more investors away from active and toward passive.
However, we believe active management has an important place, too. We often equate investing to flying a plane. For much of the flight, the pilot has the plane in autopilot—that’s passive investing. But for take-off, landing, and times of turbulence the pilot is very much needed. (Read more: Why We Believe in a Symbiotic Active/Passive Investment Approach.)
In our view, employing a passive component is not a bet against active management, but is instead a strategy to seek a degree of certainty that a portfolio, on at least a portion of its assets, may match the market return. The key consideration, then, is how to incorporate active and/or passive investment management into a successful asset allocation strategy.
At Monetta, we launched the Monetta Core Growth Fund (formerly the Monetta Young Investor Fund) in 2006, not long before the start of Warren Buffett’s 10-year bet. Its mix of active and passive components is approximately 50/50, which is adjusted in the event of unusual situations. Over the same 10-year period covered by Warren Buffett’s bet (ending December 31, 2017), the Fund achieved an average annual return of 12.2%, which equates to a cumulative return on 216.3%. (See performance table below for full historical performance figures.)
The Fund’s 10-year result over the period of Warren Buffett’s bet far outpaces the S&P 500’s average annual return of 8.5%, which equates to 125.8% on a cumulative basis, as reported in Buffett’s letter.
We believe the Fund’s performance supports our view that both active and passive approaches have their merits—and are best applied in symbiotic combination for the opportunity to generate above average market returns.

The Morningstar Rating™ for funds, or “star rating”, is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product’s monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating™ for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating™ metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. The Monetta Core Growth Fund received 3 stars among 1265 for the three-year, 2 stars among 1141 for the five-year, and 5 stars among 825 Large Growth funds for the ten-year period ending 6/30/18.
Morningstar Risk Rating: An annualized measure of a fund’s downside volatility over a three-, five-, or ten-year period. This is a component of the Morningstar Risk-Adjusted Return. Morningstar Risk is displayed in decimal format. A high number indicates higher risk and low numbers indicate lower risk. In each Morningstar Category, the top 10% of investments earn a High rating, the next 22.5% Above Average, the middle 35% Average, the next 22.5% Below Average, and the bottom 10% Low. Morningstar Return Rating: An annualized measure of a fund’s load-adjusted excess return relative to the return of the 90-day Treasury Bill over a three-, five-, or ten-year period. This is a component of the Morningstar Risk-Adjusted Return. Morningstar Return Rating is derived directly from Morningstar Return. In each Morningstar Category, the top 10% of investments earn a High rating, the next 22.5% Above Average, the middle 35% Average, the next 22.5% Below Average, and the bottom 10% Low. Morningstar Risk and Return Ratings are calculated only for those investments with at least three years of performance history.
