If you've got a good enough business, if you have a monopoly newspaper, if you have a network television station - I'm talking of the past - you know, your idiot nephew could run it. And if you've got a really good business, it doesn't make any difference.
Investors... can't pick stocks that are better than average. Stocks are a good thing to own over time. There's only two things you can do wrong: You can buy the wrong ones, and you can buy or sell them at the wrong time. And the truth is you never need to sell them.
The problem with commodities is that you are betting on what someone else would pay for them in six months. The commodity itself isn't going to do anything for you....it is an entirely different game to buy a lump of something and hope that somebody else pays you more for that lump two years from now than it is to buy something that you expect to produce income for you over time.
There are three important principles to Graham's approach. [The first is to look at stocks as fractional shares of a business, which] gives you an entirely different view than most people who are in the market. [The second principle is the margin-of-safety concept, which] gives you the competitive advantage. [The third is having a true investor's attitude toward the stock market, which] if you have that attitude, you start out ahead of 99 percent of all the people who are operating in the stock market - it's an enormous advantage.
I certainly have no desire to sell a good controlled business run by people I like and admire, merely to obtain a fancy price. However, specific conditions may cause the sale of one operating unit at some point.
