The Intelligent Investor by Benjamin Graham Summary & Book Review-

The Intelligent Investor by Benjamin Graham, also referred as the bible of the stock market, was originally written in 1949 by Benjamin Graham, a legendary investor and also known as the father of value investing.

Ben Graham was also the mentor and professor of well-known billionaire investor, Warren Buffett.

The 2006 revised edition of the book ‘The Intelligent Investor’ has added commentary by Jason Zweig, a famous wall-street investor, and editor. These added commentaries are used to relate Graham’s idea to the present world. It highlights that the book has time-tested techniques. The book has over 600 pages (although originally around 500 page but the added commentaries in revised edition increased the width of the book). Overall, it’s a classic book with added quick notes.

Why You Should Read This Book:

Warren Buffett (worth over 73.1 billion dollars) says- ‘This book is by far the best book on investing ever written’. Needless to mention that this book is Warren Buffett’s all-time favorite. He also admitted that the book helped him in developing a conceptual framework for his future investments and capital allocations. Further, he made the following remarks about the book in its preface:

  • Investing doesn’t require a stratospheric IQ, unusual business insights, or inside information. What’s needed is a sound intellectual framework for making decisions and the ability to keep emotions from corroding that framework. This book precisely and clearly prescribes the proper framework.
  • Pay special attention to chapters 8 & 20.

The Intelligent investor by Benjamin Graham book has a number of great concepts and a must read for all the stock market investors. The first few chapters of the book are dedicated to the general concepts of the market. As the book was originally written in 1949, the book has lots of details about the bonds, preferred stocks & inflation. The next few chapters describe the methods to analyze stocks, concerning balance sheet, cash flow etc. The second half of the book is of more importance for the stock investors as it explains the different strategies of the defensive & enterprising investors, along with chapters on management, dividend policy, and case studies.

The three main points covered in the books:

Although there are lots of concepts covered in the book, however, the key three points in the book the intelligent investor by Benjamin Graham can be summarized here from the book:

  1. Investing vs. Speculating

    “An investment operation is one which, upon thorough analysis, promises safety of principal and a satisfactory return. Operations not meeting these requirements are speculative.”
    – Benjamin Graham

    Let’s understand this concept with the help of an example. Imagine you are planning to buy a printing company. Now, to buy this company you can use two approaches.

    First, you visited the company, calculated the asset value of the printing shops, checked the total income and cash flow of the company, verified the effectiveness of the managers, established the total assets & liabilities and then finally come up with a final price for the printing company.

    The second approach is that you met with the owner, and decided to pay the price whatever he is asking for.

    From the example, we can establish the difference between an investor and a speculator. The Investor follows the first approach while the speculator follows the other. Here is the key difference between these two:

     

Investor Speculator
1.       Goes through thorough analysis Does not meet these standards.
2.       Considers safety of principle
3.       Gets adequate returns


Here is the quote about Speculators by Benjamin Graham:

  1. Margin of Safety

    This is another one of the pronounced concept introduced by Benjamin Franklin. He says that one should always invest with a margin of safety. Let us understand this by an example.

    Imagine you are in a construction business. You took an order to make a bridge, which can hold up to 8 tons. Now, as a constructor, you must consider making the bridge with additional 2 tons of weight holding capacity so that it will not collapse in some extra-ordinary situation. So, you will make the bridge with a total of 10 tons with holding capacity.

    Here, your 2 tons additional is the margin of safety.

    In the same way, while investing also we consider this margin of safety. It is the central concept of value investing.  If you think a stock is valued at Rs 100 per share (fairly), there is no harm in giving yourself some benefit of the doubt about if you are wrong about this calculation and buy at Rs 70, Rs 80 or Rs 90 instead. Here, the difference in the amount is your margin of safety. Here is the quote about the margin of safety by Benjamin Graham:

  1. Mr. Market
In the book ‘The Intelligent Investor’, Graham tells a story about a man he calls Mr. Market. In the story, Mr. Market is a business partner of yours. Every day Mr. Market comes to your door and offers to either buy you out of the partnership or sell you his stake in it.

But here’s the catch: Mr. Market is an emotional man who lets his enthusiasm and despair affect the price he is willing to buy/sell shares on any given day. Because of this, on some days he’ll come to the door feeling jubilant and will offer you a high price for your share of the business and demand a similarly high price if you want to buy his. On other days, Mr. Market will be inconsolably depressed and will be willing to sell you his stake for a very low price, but will also only give you the same lowball offer if you want to sell your stake.

On any given day you can obviously buy from or sell to Mr. Market, but you also have the option of completely ignoring him i.e. you don’t need to trade at all with Mr. Market. If you do ignore him, he never holds it against you and always comes back the following day.

The intelligent investor will attempt to take advantage of Mr. Market by buying low and selling high.  There is no need to feel guilty for ripping off Mr. Market; after all, he is setting the price. As an intelligent investor you are doing business with him only when it’s to your advantage; that’s all. The key point to note here is that though Mr. Market offers some great deals from time to time, investors just have to be alert and ready when those offers come up.

Mr. Market and Stock Market Co relativity:

Now, like Mr. Market, the stock market also behaves the same manner. The market swings give an intelligent investor the opportunities to buy low and sell high. Every day we can pull up quotes for various stocks or for the entire market as a whole. If we think the prices are low in relation to value, we can buy; if we think prices are high in relation to value, we can sell; and if prices fall somewhere in the grey area in between, we’re never forced to do either.

So, this is a value-oriented disciplined investing. Don’t fall victim to irrational exuberance if the underlying book value and company are strong. Meaning doesn’t react to the hyperboles of the market’s daily fluctuations. Don’t panic, don’t sell.

The Intelligent Investor by Benjamin Graham

Other key points from the book The Intelligent Investor by Benjamin Graham on the Investor and market fluctuations:

  • A common stock portfolio is certain to fluctuate over any period of time.
  • The investor should be prepared financially and psychologically for this fluctuation. Investors will want to profit from market level changes. But this can lead to speculative attitudes and activities which can be dangerous. Therefore ‘If you want to speculate do so with eyes open, and knowledge that you will probably lose money in the end’.
  • Graham’s Opinion on Aggressive Investors:
    The low probability of aggressive picks will out-weigh the gains collected over a long period of time. ‘The aggressive investor will expect to fare better than his passive equivalent, but his results may well be worse.’

I hope this post about the ‘The Intelligent Investor Summary & Book Review’ is helpful to the readers. I will highly recommend you to get a copy of this book and start reading. There are many concepts by Benjamin Graham that new and old stock investors can learn.
