Benjamin Graham: Lecture 1

I have decided to make a detailed study of the lectures that Graham gave while he was a professor at Columbia Business School.

You can access the transcripts of the lectures here.

In the first lecture, Graham states that the purpose of these series of lectures is to identify the current problems in security analysis. It is also to provide an update on the textbook, "Security Analysis".

The most pressing problem identified was that security analysts read too much into the stock market. They should only strive to provide an analysis of the securities at question and not try to become a market analyst by trying to predict the direction of the market.

However, Graham goes on to preach that one can observe the following principles when studying the behavior of stocks. The principle of continuity and the principle of deceptive selectivity.

The principle of continuity relates to the observation that stock prices do not stray far away from their fundamentals and they will approach the norms after some time. There is no such thing as a fundamental shift that occurs forever.

The principle of deceptive selectivity is the analysts' perception that they are able to yield better returns by buying stocks that have better earnings prospects which can be seen prominently. Such perception only leads to lower returns for the analysts. The method of selectivity that Graham preaches is the identification of value differentials through the application of security analysis techniques.

Graham recommends that investors avoid IPOs as these offerings are made by a well-trained sales team that ensures that you will most likely not get a good bargain.

The security analysis methodology that Graham recommends is the balance sheet method. By using this method, analysts will be able to calculate the true earnings of the company being analyzed as this method removes the impact of reserves.
