If you know how to value businesses, it's crazy to own 50 stocks or 40 stocks or 30 stocks, probably because there aren't that many wonderful businesses understandable to a single human being in all likelihood. To forego buying more of some super-wonderful business and instead put your money into #30 or #35 on your list of attractiveness just strikes Charlie and me as madness.
Anything can happen anytime in markets. And no advisor, economist, or TV commentator-and definitely not Charlie nor I-can tell you when chaos will occur. Market forecasters will fill your ear but will never fill your wallet.
An investor should ordinarily hold a small piece of an outstanding business with the same tenacity that an owner would exhibit if he owned all of that business.
