Berkshire Hathaway's latest annual report is out! That only means one thing, I get to make a video update on how Warren Buffett's portfolio has been doing over the past year!

Warren Buffett is arguably the most successful investor of all time, or at least he is the best known. The criticism of his investment strategy is that he holds large amounts of cash and cash equivalents (bonds). Currently, cash and cash equivalents have negative real returns due to low interest rates and high inflation. You could say he invests like a baby boomer, what do you think?
