1 November 1999: Microsoft and Intel join the Dow

Microsoft and Intel became the first Nasdaq-listed companies added to the Dow Jones Industrial Average, alongside Home Depot and SBC Communications. Out went Union Carbide, Goodyear, Sears and Chevron. It was a symbolic victory for the new economy at the height of the tech boom. The timing was rough: both tech giants peaked within months and took many years to regain those levels.

The lesson: Index additions often reward past winners, not guarantee future ones.

What it meant for investors

$1,000 in Intel at the start of 2000 → $976 today, vs $4,626 in the S&P 500.

We start the clock at the start of 2000, the first year in our price data after the event. That is a loss of $24.39, while a plain index fund over the same years made $3,626.

What Intel teaches: Market leadership is not permanent; Intel's manufacturing edge looked unassailable for decades and eroded through a handful of missed bets and execution slips.
