The Dot-Com Bubble: When the Internet Broke the Market

In the late 1990s, adding '.com' to a company name could send its stock soaring, even if the business had never made a dollar of profit. Then, in the spring of 2000, the whole thing came apart.

What happened

The tech-heavy Nasdaq Composite index peaked at 5,048 on March 10, 2000. Over the next two and a half years it collapsed. By October 2002 it had fallen roughly 78%, to around 1,140. More than $5 trillion in market value evaporated, and a long list of once-celebrated internet companies went bankrupt entirely.

Names that had been advertised during the Super Bowl, like Pets.com, eToys and Webvan, simply ceased to exist. Fortunes built on paper vanished, and a generation of investors learned a painful lesson about the difference between a good story and a good business.

Why it happened

The internet was real and genuinely revolutionary. That is exactly what made the bubble so seductive: the underlying story was true, even though the prices were not justified.

• A land-grab mindset. Investors believed the internet would change everything (it did), and rushed to buy any company connected to it, without asking whether that specific company could ever earn money.
• Profits didn't matter, for a while. Many dot-coms were valued on 'eyeballs' and website traffic rather than earnings. The traditional yardstick, the price-to-earnings ratio, was useless because there were often no earnings at all.
• Easy money and hot IPOs. Money poured into venture funding and initial public offerings. A company could go public, double on its first day, and its founders would be rich, whether or not it had a viable product. If that step is new to you, see what is an IPO.
• Fear of missing out. As neighbors and coworkers made money on tech stocks, more people piled in, pushing prices higher and 'proving' the believers right, until they weren't.

The aftermath

When interest rates rose and a few high-profile companies missed expectations, confidence cracked. Because so many valuations rested on belief rather than profit, there was nothing solid to catch the fall. Selling fed on itself.

The bust was brutal but it was also a filter. The companies with real businesses survived and, in some cases, went on to dominate the world. Amazon's stock fell more than 90% in the crash, yet the company endured and eventually became one of the most valuable on earth. The bubble destroyed the pretenders and left the survivors stronger.

Investors also relearned an old truth: a transformative technology and a good investment are not the same thing. Being right about the internet did not save you if you paid an absurd price for the wrong company.

The lesson

The dot-com bubble is the classic study of a market driven by narrative. When enough people believe prices can only go up, they buy simply because prices are going up, which is the definition of a bubble. Bubbles have historically ended the same way: the story stays exciting right up until the moment buyers run out.

Bubbles usually inflate during long bull markets, and the mistakes made in 2000 are the same ones covered in common beginner mistakes.
