I absolutely agree. If you could only invest in one tech company, who would have invested in Apple/Amazon/Google instead of IBM? These are now large, successful companies that were able to succeed because investors were able to hedge and invest in an entire sector.

IMHO there shouldn't be Apple/Amazon/Google/IBM companies as they are today. I want Google and other companies be splitted to AdWords, GoogleSearch, YouTube, Android, Waymo companies. And they should not use their dominant/monopolistic position in search/ads areas to get unfair advantage in other areas.

So you would have to choose your investment between Android/Apple/WinMobile OS, AdWords/AdMob ads, Waymo/Cruise cars, Google/Yahoo/DuckDuckGo search, YouTube/Vimeo videos.

Including DuckDuckGo in your list of search companies exposes one of core issues that makes this idea unworkable. DuckDuckGo is basically just a skin that shells out to Bing, Yandex, or Google.

> hedging is good.

Is it? Article says that it can be bad for customers:
