25 October 2001: Windows XP goes on sale
Microsoft launched Windows XP, combining the stability of its business software with a friendlier consumer interface. Launched into a recession and just weeks after 9/11, it nonetheless became one of the most widely used operating systems ever, still running on many machines more than a decade later. It showed the power of a dominant platform, even in a period when Microsoft's own stock was going nowhere.
The lesson: A great business and a great stock are not the same thing in every decade.
What it meant for investors
$1,000 in Microsoft at the start of 2003 → $24,000 today, vs $7,727 in the S&P 500.
We start the clock at the start of 2003, the first year in our price data after the event. That is 24.0 times the money, and $16,273 more than a plain index fund made over the same years.
What Microsoft teaches: A great business bought at a silly price can still deliver a lost decade; Microsoft's profits grew for years while its 2000 valuation slowly deflated.
| Bought in | Price then | Worth today | S&P 500 would be |
|---|---|---|---|
| 2003 | $20.00 | $24,000 | $7,727 |
| 2005 | $27.00 | $17,778 | $5,763 |
| 2007 | $30.00 | $16,000 | $4,789 |
green = beat the S&P 500 · red = lost money
