- stock market returns were abnormally high for the past 15 years
- Berkshire is sitting on a huge pile of cash, ready to invest
This is a very similar scenario to what people were saying in 1999 - Buffett is done etc. I highly recommend reading his biography - "The Snowball" and especially the preface when they describe the speech he gave in 1999, about stock market levels and valuations. Mind blowing, knowing what happened later.
