How to Build a Complete Benjamin Graham Portfolio
Posted by: SerenityStocks (IP Logged)
Date: November 30, 2012 10:05AM

Benjamin Graham was an economist and professional investor who taught Warren Buffett, Irving Kahn, Walter J. Schloss and other famous investors at Columbia Business School.

Buffett, who credits Graham with grounding him with a sound intellectual investment framework, describes Graham as the second most influential person in his life after his own father. In fact, Graham had such an overwhelming influence on his students that two of them, Buffett and Kahn, named their sons after him.

In the preface to Graham's book, "The Intelligent Investor," Buffett calls it "by far the best book about investing ever written."

Greater Effort, Greater Returns

Contrary to common thinking that greater profits require greater risks, Graham said that if he had to distill the secret of sound investment into three words, they would be "margin of safety." The chapter on "margin of safety" in Graham's book is also the one most highly recommended by Buffett.

Graham taught that the returns an investor could expect were not proportional to the risk he was willing to assume, but rather, to the effort he was willing to put into his investments. He thus recommended various investing strategies that offered differing returns, and required varying degrees of the diligence.

In this article, we will look at each of these strategies in turn, and see how one can implement them today.

Strategy 1: Zero Effort - Index Funds

Graham often emphasized that most mutual funds did not beat the market average, as measured by the indices. He thus recommended that the first strategy for any investor -- one that required nearly no effort -- was to proportionally invest in stocks listed in the indices. This is something that can be done a lot more easily today, by simply investing in an index fund.
Quote:
Quoted from Chapter 14 of The Intelligent Investor - Stock Selection for the Defensive Investor:

"In setting up this diversified list he has a choice of two approaches, the DJIA-type of portfolio and the quantitatively- tested portfolio. In the first he acquires a true cross-section sample of the leading issues....[shortened]... This could be done, most simply perhaps, by buying the same amounts of all thirty of the issues in the Dow-Jones Industrial Average."
Thus it would be safe to say that Graham's first recommended strategy today would be to invest in a reputed index fund following a popular index like the DIJA or the S&P 500. Graham believed that the choice of index would make very little difference.

General research on fund performance seems to indicate that the S&P 500 Index Funds rate the highest, especially against managed mutual funds (as expected). Some of the best performing S&P 500 Index Funds appear to be those by Vanguard (VFINX), Fidelity (FUSEX) and Schwab (SWPPX).

However, there are numerous resources available online specifically for the purpose of analyzing index funds. So we shall move on to the more complex, and more profitable, of Graham's strategies — the ones concerning the selection of stocks.

Strategy 2: Minimum Effort: Defensive Grade Stocks

The first grade of stocks recommended by Graham are called "defensive" stocks. The criteria that Graham specified for identifying defensive stocks are as follows:
Quote:
Summarized from Chapter 14 of The Intelligent Investor - Stock Selection for the Defensive Investor:

1. Not less than $100 million of annual sales.

[Note: This works out to $500 million today based on the difference in CPI/Inflation from 1973]

2-A. Current assets should be at least twice current liabilities.

2-B. Long-term debt should not exceed the net current assets.

3. Some earnings for the common stock in each of the past 10 years.

4. Uninterrupted [dividend] payments for at least the past 20 years.

5. A minimum increase of at least one-third in per-share earnings in the past 10 years.

6. Current price should not be more than 15 times average earnings.

7. Current price should not be more than 1-1⁄2 times the book value.

As a rule of thumb, we suggest that the product of the multiplier times the ratio of price to book value should not exceed 22.5.
Graham's recommended price for defensive stocks can be calculated from criteria No. 6 and No. 7 as the square root of (22.5 x EPS x BVPS). This price is popularly known as the Graham number.

Graham recommended a minimum portfolio size of 10 and a maximum of 30 for defensive investors. Since defensive stocks are the most well established stocks meeting the most stringent of criteria, the effort required to create and maintain the portfolio can be reduced to a minimum by restricting the portfolio to 10 defensive stocks.

A full Graham analysis of all 4000 NYSE and Nasdaq stocks brings up 12 stocks meeting all of Graham's defensive criteria today, even with calculations adjusted for inflation. Shown here are the first 10 from the Comprehensive Graham Screener:

To better understand how this result was arrived at, let us look at the detailed analysis for the first of these stocks - Baker Hughes Inc. (BHI).

The first section on BHI's page gives some useful financial ratios. But this information is not directly required for the actual Graham analysis.

The next section is of more interest since it gives an individual rating for each of the eight defensive criteria specified by Graham. As can be seen, BHI scores more than 100% on all ratings, as is required for an approved defensive stock.

But the most important section is the last one. This section gives all the three different Graham prices for a stock, and then gives the final Graham analysis for the stock. In the case of BHI, it shows that BHI is a defensive stock, and hence BHI's final Graham price is the same as its Graham Number. Finally, this section shows that the current price of this stock is less than its Graham price, so the stock is approved for purchase.

The Comprehensive Graham Screener, which deals with this final Graham analysis, is the most important screener on Serenity and is described at the end of the article.

Strategy 3: Medium Effort: Enterprising Grade Stocks

For enterprising investors who are looking for greater profits, and are willing to put in more effort into the maintenance of their portfolio, Graham then recommends the following criteria for identifying "enterprising" grade stocks:
Quote:
Summarized from Chapter 15 of The Intelligent Investor - Stock Selection for the Enterprising Investor:

[Note: For issues selling at P/E multipliers under 10]

1-A. Current assets at least 1 1⁄2 times current liabilities.

1-B. Debt not more than 110% of net current assets.

2. Earnings stability: No deficit in the last five years covered in the Stock Guide.

3. Dividend record: Some current dividend.

4. Earnings growth: Last year's earnings more than those of 1966.

[Note: This corresponds approximately to the earnings of 2007 today]

5. Price: Less than 120% net tangible assets.
This second set of criteria gives us a Graham price for a stock meeting enterprising conditions as the lower of 120% net tangible assets (book value), or 10 times current earnings.

Since enterprising stocks are not as well established as defensive stocks, the portfolio needs to be diversified more. Serenity's recommendation is for a minimum of 20 enterprising stocks. Such a portfolio will also require more effort in the selection, verification, tracking and balancing of the component stocks.

An automated analysis of all 4000 NYSE and Nasdaq stocks brings up 25 stocks meeting all of Graham's enterprising criteria today, with calculations adjusted for inflation. Shown here are the first 10 from the Comprehensive Graham Screener:

Strategy 4: Maximum Effort - NCAV Grade Stocks

For investors who were willing to put in the most effort into the maintenance of their portfolio, Graham finally recommended NCAV grade stocks, which he defined as:
Quote:
Summarized from Chapter 15 of The Intelligent Investor - Stock Selection for the Enterprising Investor:

"Bargain Issues, or Net-Current-Asset Stocks"

"...price less than the applicable net current assets alone - after deducting all prior claims, and counting as zero the fixed and other assets."

"...eliminated those which had reported net losses in the last 12-month period."
These criteria give us stocks selling for less than the value of their cash worth alone, and with positive earnings in the last one year. These stocks are also the most famous of Graham's stocks, and the source of the general misconception that Graham only recommended cheap stocks. These were, in fact, the last grade of stocks that Graham recommended.

Since NCAV stocks are the least established stocks of all stocks, such a portfolio will have to be the most diversified, requiring at least 30 NCAV stocks. Such a portfolio will also require the most effort in the selection, verification, tracking and balancing of its component stocks.

An automated analysis of all 4000 NYSE and NASDAQ stocks brings up more than 300 stocks meeting all of Graham's NCAV criteria today, with calculations adjusted for inflation. Shown here are the first 10 from the Comprehensive Graham Screener:

Strategy 5: Special Situations or "Workouts"

Graham considered special situations theoretically a part of the program of operations of an enterprising investor, but classified them as a business altogether different from regular investing.

As the name indicates, these are special strategies that follow no specific rules or calculations. Some of the operations that Graham classified under this category are acquisitions of smaller firms by larger ones, arbitrage operations, the breakup of public-utility holding companies pursuant to legislation, issues that are involved in any sort of complicated legal proceedings and with prices beaten down to unduly low levels due to the ensuing prejudice, etc.

Being able to identify and take advantage of a special situation requires years of experience with Graham's previous strategies. Graham himself wrote:
Quote:
"The exploitation of special situations is a technical branch of investment which requires a somewhat unusual mentality and equipment. Probably only a small percentage of our enterprising investors are likely to engage in it..."
And elsewhere, he noted about "workout or arbitrage" opportunities:
Quote:
"This has become more than ever a field for professionals, with the requisite experience and judgment..."
Thus, special situations will need to be studied on a case-by-case basis and are not open to any general analysis. But any investment of this kind will still need to meet Graham's basic requirements of a margin of safety, as well as his definition of an investment operation (as distinguished from speculation).
Quote:
"An investment operation is one which, upon thorough analysis, promises safety of principal and an adequate return. Operations not meeting these requirements are speculative."
Checking for Splits

When using strategies Nos. 2, 3 and 4 — after the investor has shortlisted his preferred combination of defensive, enterprising and NCAV grade stocks — the next most important step is to verify the stocks for any recent splits. The book value and EPS data for a stock that has just been split are not usually publicly disseminated until the next financial cycle. Thus, while the market price will already reflect the reduced split price, the public financial data for the stock might still wrongly indicate the previous higher Graham price.

Only once it is clear that the selected stocks have not been split since they last announced their financial results — and do, in fact, meet Graham's criteria for investment — do we proceed to the final steps, which are to quickly verify the data used for analyzing the stocks and place the required orders.

To Conclude

The effort Graham foresaw in investing was not only in finding and verifying stocks, but also in monitoring and balancing the portfolio — selling stocks that have corrected themselves and buying new ones, etc. Thus, the more stocks in your portfolio, the greater is the overall effort involved.

So it's important to choose an investment strategy carefully. A good approach would be to start with a low effort strategy and evolve as you get more comfortable; possibly starting with 10 defensive stocks, and gradually replacing 5 of them for 10 enterprising ones and so on.

Graham's principles have been recommended again and again over the years — by Buffett and by Graham's other students — in books and in speeches. Buffett even gave a famous speech in 1984, called "The Superinvestors of Graham and Doddsville" about why the most successful investors in the world were all students of Graham.

The Free Comprehensive Graham Screener on Serenity can be used to select the best defensive, enterprising and NCAV stocks from all 4000 NYSE and Nasdaq stocks today. By default, the screener lists all stocks that are selling for less than their Graham price, with defensive grade stocks listed first, followed by enterprising grade stocks and then NCAV grade stocks. The drop-down menus at the top of the screener can be used to select specific grades, and generate lists of approved stocks like the ones shown in this article.

Disclaimer: The results were arrived at by automated quantitative analysis and were not verified manually. Verify the validity of the data used — most importantly, for any recent stock splits — before making an investment decision.
