Ground Rule #4: “Whether we do a good job or a poor job is not to be measured by whether we are plus or minus for the year. It is instead to be measured against the general experience in securities as measured by the Dow Jones Industrial Average, leading investment companies, etc. If our record is better than that of these yardsticks, we consider it a good year whether we are plus or minus. If we do poorer, we deserve the tomatoes.”
