Successful investing demands that investors constantly supply themselves with information. Because the business world is always changing, you can never learn too much. Just look at the newspaper industry. Who could have predicted that the Internet would come along and permanently alter the economics of that entire sector? If you want to be an effective investor, you need to keep up with those twists and turns and never stop educating yourself.
Turn those pages
Thinking independently is the greatest attribute an investor can have. To think independently, you need to expose yourself to a variety of sources. And to do that, you have to read. A lot. The Wall Street Journal is one excellent source that you should read every day. But that just scratches the surface. Fine periodicals such as Barron's, Business Week, The Financial Times, The Economist, and others will further enrich you with their independent perspectives, as will online sources such as Value Line and, of course, The Motley Fool.
After that, the real fun begins: annual reports. There is no substitute for the information you gain from reading them. Not only will they educate you about a particular company, but they'll also give you insight into industries, their managements, and entire perspectives on how various businesses operate. You'll always have more reading to do than available time, since there are literally thousands of annual reports out there, but full-time investors should make a habit of reading at least a couple of reports a day. Keep it up for a few years, and you'll begin to develop a mental model of businesses and industries.
Although spending time with any annual report will yield value, there are a few you must read, without exception. The most obvious one is the Berkshire Hathaway
Equally important, I think, is the annual report from Wal-Mart
Also on the must-read list is General Electric's
For that matter, you should try to read all of the annual reports from major global companies, including ExxonMobil
Always be prepared
The Internet reshaped the newspaper industry, but it has also helped reduce the time required to access information. However, you still have to apply the effort to dig in and learn. There are no shortcuts. The bright side is that the payoff from all this work is enormous. In my next article, I'll discuss the next habit investors should nurture to complement all of their reading.
