Young Money blog on the bubble in Big Tech

Today, America's five largest companies by market capitalization are all well-known technology and internet businesses: in descending order, Apple, Amazon, Microsoft, Alphabet (the parent company of Google), and Facebook. Historically, being one of the top companies by market cap has been a contrary indicator, both for the company itself and for the industry to which it belongs. In 1980, right before a decade-long decline in oil prices, six of the top ten were oil companies. In 2000, at the peak of the dotcom bubble, six of the top ten were computer and internet companies.

I think history will repeat and that none of today's Big Five will grow enough to justify its current market cap.
