The (Non) Lessons of History–and the (Real) Lessons of Return Sources and Investment Costs
From its lowly beginning in 1948 with my struggle to absorb his Economics textbook, my association with Paul Samuelson had a wonderful turnaround. While I had hinted at the merit of an index fund in my Princeton thesis (mutual funds “can make no claim to superiority over the market averages”), I ignored that important finding for years. But in mid-1975, I decided that the time was ripe for the world’s first index fund, importantly because of Paul Samuelson’s inspiration. That inspiration came when I read his lead essay in the inaugural edition of The Journal of Portfolio Management (Fall 1974). In his essay, “Challenge to Judgment,” Dr. Samuelson explicitly called for those who disagreed that a passive index would outperform most active managers to produce “brute evidence to the contrary.” (None was forthcoming.) He pleaded “that, at the least, some large foundation set up an in-house portfolio that tracks the S&P 500 Index—for the purpose of setting up a naïve model against which their in-house gunslingers can measure their prowess.” Confronted with his express challenge for somebody, somewhere to start an index fund, I could no longer stand back. It now seemed clear that the newly-formed Vanguard Group (then only a few months old) ought to be “in the vanguard” of this new and logical concept, so strongly supported by the data on past fund performance, and so well accepted in academia but so little acknowledged by fund industry leaders.
