“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,” said Warren Buffett in his 1996 letter to Berkshire shareholders. “Should you choose, however, to construct your own portfolio, there are a few thoughts worth remembering.
