Museum of American Finance Marks the 50th Anniversary of the First Index Fund Available to Individual Investors
By Gregory DL Morris, Research Associate
On October 14, the Museum of American Finance unveiled the display of a rare certificate from the first index mutual fund, in honor of its 50th anniversary. The certificate is on loan from Vanguard and will be on view through April 11, 2027.
“ We are proud to add to our exhibits the display of the first index mutual fund certificate during this important anniversary year,” said MoAF President / CEO David Cowen.“ We believe it will add to our visitors’ understanding of this important investing tool, as we strive to equip them with knowledge that will help them better their financial lives.”
In his 1951 undergraduate thesis at Princeton University, John C. Bogle( 1929-2019) highlighted the crucial role of costs in the long-term returns earned by investors. He identified costs as a drag on the performance of the industry, which was then entirely actively managed. As the founder of Vanguard, Bogle put his thesis to work and created the index fund, now a staple of retail investing.
When Bogle launched the First Index Investment Trust( now called the Vanguard 500 Index Fund) on August 31, 1976, he solved two challenges for individual investors. Professional advisors charged high fees and trading commissions to manage a portfolio of stocks, so investing was mostly restricted to institutions and the wealthy. Indexing— the strategy of simply matching market performance by holding a broad basket of representative stocks— had lower trading costs, but still high fees for calculating and adjusting the benchmark index.
By creating an index mutual fund, Bogle gave individual investors access to
an indexing strategy and the advantages of low-cost investing in a mutual fund that allowed them to buy and sell at any time. In later years, Bogle often summarized the concept by saying,“ Don’ t look for a needle in a haystack; just buy the haystack.”
Despite a slow start, indexing gained adherents because it is an easy-to-understand, cost-effective strategy that can offer diversification, tax efficiency and consistent performance relative to the results of the market.
“ Few innovations have done more than index funds to expand access and help investors build wealth over time,” said Greg Davis, president and CIO of Vanguard.“ The fundamental promise of indexing remains unchanged: broad diversification, low costs and the power of staying invested for the long term.”
On October 13, Mike Nolan and Emily Cottle from Vanguard installed the certificate from the first index mutual fund in the Museum’ s Boston gallery. The display opened to the public the following day.
