"" If we accept the proposition that the typical active investor underperforms the broad market, then we would have to conclude that the "know nothing" investor who dollar cost averages into a broad index will end up with better performance in the long run. This is one of the great ironies of investing!

In my case, choosing to invest in Berkshire Hathaway was the right choice, both in terms of performance and owning an asset that I could understand and identify with over long periods of time. Warren Buffett and Charlie Munger never guaranteed results, but they did guarantee that their economic outcome would match my outcome and I knew with certainty that I would be treated fairly. That knowledge allowed me to stay the course through some very tough periods.""
