26 May 1896: The Dow Jones Industrial Average debuts

Charles Dow published his industrial average for the first time on May 26, 1896, at 40.94. It contained 12 companies, including makers of cotton oil, sugar, leather and tobacco. General Electric was the only original member still in the average more than a century later, until it was removed in 2018. The rest were merged, renamed or disappeared, which says something about permanence in business.

The lesson: Indexes survive by replacing losers with winners; individual companies get no such second chance.

What it meant for investors

$1,000 in S&P 500 index fund at the start of 1990 → $19,429 today, vs $19,429 in the S&P 500.

We start the clock at the start of 1990, the first year in our price data after the event. That is 19.4 times the money, but $0 less than a plain index fund made over the same years.

What S&P 500 index fund teaches: Owning the whole market removes the risk of picking the wrong company but not the risk of a lost decade, so time horizon matters as much as diversification.
