And yet Berkshire tripled their GOOGL (+GOOG) position in Q1. Apparently they weren't concerned about their "tanking" free cash flow yield. What do they know that we don't?

How to invest with a long time frame?

A very high valuation level compared to its own history, and a huge weight from the capital needed in the next few years. And yet, if (if) those are issues that go away in the next few years, they will still be in business and generating remarkable value per share for decades to come. I don't know if things will work out that way, but I presume that is the thinking. Head office is probably reacting to the rally since March as "Dang, we'll have to stop buying for a while".

I sold my last shares not long ago due simply to valuation concerns, but the very best long term investors don't do that when the firm has serious staying power. One of the things they know that I don't. That's not necessarily a paradox: Berkshire and Alphabet will outlive me.
