In a world where non-stop financial commentary is as commonplace as it is tedious, one man’s market insights get an unusual amount of attention: Warren Buffett’s annual shareholder letter.

He’s doubtlessly inspired more people to found RIAs than any other individual, yet his firm, Berkshire Hathaway, is not an RIA. And his annual treatise on the performance of his company is full of common-sense wisdom that, based on Berkshire’s track record, is anything but common.
