Though business conditions may change, corporations and securities may change, and financial institutions and regulations may change, human nature remains the same. Thus the important and difficult part of sound investment, which hinges upon the investor's own temperament and attitude, is not much affected by the passing years.
Basically, price fluctuations have only one significant meaning for the true investor. They provide him with an opportunity to buy wisely when prices fall sharply and to sell wisely when they advance a great deal. At other times he will do better if he forgets about the stock market and pays attention to his dividend returns and to the operating results of his companies.
All the real money in investment will have to be made—as most of it has been in the past— not out of buying and selling but out of owning and holding securities, receiving interests and dividends therein, and benefiting from their long-term increases in value. Hence stockholder's major energies and wisdom as investors should be directed toward assuring themselves of the best operating results from their corporations. This in turn means assuring themselves of fully honest and competent managements.
