Warren Buffett on intelligent investing


One of the best gems on investment success from Warren Buffett came in his letter (dated Feb 28, 1997 for FY1996) to Berkshire Hathaway shareholders.

Warren Buffett said: “Most investors, both institutional and individual, will find that the best way to own common stocks is through an index fund that charges minimal fees. Those following this path are sure to beat the net results (after fees and expenses) delivered by the great majority of investment professionals. Should you choose, however, to construct your own portfolio, there are a few thoughts worth remembering. “Intelligent investing is not complex, though that is far from saying that it is easy. What an investor needs is the ability to correctly evaluate selected businesses. Note that word “selected”: You don’t have to be an expert on every company, or even many. You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.

“To invest successfully, you need not understand beta, efficient markets, modern portfolio theory, option pricing or emerging markets. You may, in fact, be better off knowing nothing of these. That, of course, is not the prevailing view at most business schools, whose finance curriculum tends to be dominated by such subjects. In our view, though, investment students need only two well-taught courses – How to Value a Business, and How to Think About Market Prices.

“Your goal as an investor should simply be to purchase, at a rational price, a part interest in an easily-understandable business whose earnings are virtually certain to be materially higher five, ten and twenty years from now. Over time, you will find only a few companies that meet these standards – so when you see one that qualifies, you should buy a meaningful amount of stock. You must also resist the temptation to stray from your guidelines: If you aren’t willing to own a stock for ten years, don’t even think about owning it for ten minutes. Put together a portfolio of companies whose aggregate earnings march upward over the years, and so also will the portfolio’s market value.

“Though it’s seldom recognized, this is the exact approach that has produced gains for Berkshire shareholders: Our look-through earnings have grown at a good clip over the years, and our stock price has risen correspondingly. Had those gains in earnings not materialized, there would have been little increase in Berkshire’s value.

“The greatly enlarged earnings base we now enjoy will inevitably cause our future gains to lag those of the past. We will continue, however, to push in the directions we always have. We will try to build earnings by running our present businesses well – a job made easy because of the extraordinary talents of our operating managers – and by purchasing other businesses, in whole or in part, that are not likely to be roiled by change and that possess important competitive advantages.”
