At the Daily Journal Corporation Annual Shareholders’ Meeting 2018 (14-Feb-2018,) Charlie Munger opined about the size of Berkshire Hathaway and the disadvantages it imparts on its success:

Berkshire succeeded because there were very few big errors… there were like no big errors, really big. And there were a considerable number of successes. All of which would have been much harder to get under present conditions than they were at the time we got the results. And there are very few companies that have compounded at 19% per annum for fifty years. It’s (a weird) in net worth. That is very peculiar. I wouldn’t count on that happening again soon.
