24 March 2000: The S&P 500 peaks in the dot-com bubble

The S&P 500 closed at a record 1,527.46, the high point of the dot-com era for the broad market. Technology stocks made up an unusually large share of the index. Over the next two and a half years it would fall nearly half. Investors who bought an index fund at the peak waited about seven years just to break even, and longer after inflation. Even diversification cannot protect you from overpaying.

The lesson: Buying a whole market at a bubble price still means buying at a bubble price.

What it meant for investors

$1,000 in S&P 500 index fund at the start of 2000 → $4,626 today, vs $4,626 in the S&P 500.

We start the clock at the start of 2000, the year it happened. That is 4.6 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.
