Will Technology Stocks be the Leaders of the 2020s?

In 2021, the 10 largest companies in the world were technology stocks. Technology changed our lives, and the companies on the top 10 list are prominent names including Apple, Microsoft, Alphabet (Google’s parent company), Amazon, Facebook and Tesla. Investing in such a prominent sector seems like a no-brainer – they are the future, and should stay dominant. While they declined more than the general stock market in 2021, it may seem reasonable to expect them to recover fast and continue their dominance.

It turns out that every decade or so, the top 10 most valuable companies in the world were dominated by a group that people fell in love with. In 1980 it was oil stocks, 1990: Japanese stocks, 2000: tech stocks, 2010: Chinese & energy stocks, 2021: tech stocks. (See the well-written article: https://mcusercontent.com/6750faf5c6091bc898da154ff/files/8a56f057-ed95-f5a2-56e2-cc7a5b72247d/GKDailyComment221206.pdf.)

Every time, there was a rational explanation for the dominance of the companies, and the continued dominance. While the story always sounded convincing, it never worked out. The world’s production isn’t driven by one sector. By the next decade, the favorite group underperformed, sometimes with decade-long declines, and got replaced by the next favorite.

Here are several tools to identify these situations:

  1. A group of stocks dominated the largest 10 companies in the world (by market cap = investment value).
  2. The valuations of this group of stocks were extremely high (measured by Price/Book Value, or P/B).
  3. The bubble popped, and the group of stocks underperformed the rest of the market for a number of months.

Once all 3 happened, the initial declines were not followed by a return to dominance in the following decade. Can you guess how many of these 3 applied to technology stocks in 2021? All 3! Seeing the dominant groups of stocks in each of the recent decades, can you guess the dominant group in the 2020’s?

Note that this article discussed investments, not intrinsic values of companies. To understand better, Price = book x price/book. The book value (or intrinsic value) of a company can grow nicely, but if the price/book starts very high and corrects itself, the price can still decline or grow much more slowly. This is how some great dominant companies in each decade end up being poor performers as investments.
