Graham's Stock Grades
Serenity's Assessment Results
Graham's Stock Grades
Graham recommended three categories of stocks, with seventeen qualitative and quantitative specifications.
These were the highest quality (and costliest) stocks Graham recommended, and were required to have:
1. Not less than $100 million of annual sales.
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 ten 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 ten years using three-year averages at the beginning and end.
6. Current price should not be more than 15 times average earnings of the past three years.
7. Current price should not be more than 1½ 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.
Criterion #1 works out to $500 million today when adjusted for inflation.
Graham recommended a minimum portfolio size of 10 for Defensive grade stocks; or in other words, not more than 10% of one's portfolio per Defensive grade stock.
Note: Graham allowed for individual exceptions to the above, if the portfolio as a whole cleared all criteria. Graham also noted that Utilities were more likely to clear the above; and modified criteria #1, #2-A and #2-B for Utilities and Financials.
For more Enterprising (or aggressive) investors, Graham recommended stocks "selling at multipliers under 10" that also had:
1-A. Current assets at least 1½ 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.
5. Price: Less than 120% net tangible assets.
For criterion #4, Serenity compares last year's earnings to that of 4 years ago.
Serenity recommends a minimum portfolio size of 20 for Enterprising grade stocks; or in other words, not more than 5% of one's portfolio per Enterprising grade stock.
3. NCAV (Net Current Asset Value or Net-Net)
Graham's most well-known category of stocks actually included criteria for Earnings and Diversification as well.
1. A diversified group of common stocks at a price less than the applicable net current assets alone — after deducting all prior claims, and counting as zero the fixed and other assets.
2. Eliminated those which had reported net losses in the last 12-month period.
Graham recommended a portfolio size of 30 for NCAV grade stocks; or in other words, not more than 3.3% of one's portfolio per NCAV grade stock.
Serenity's Assessment Results
Serenity applies all of the above Graham criteria to global equity markets, giving the following four results.
1. Intrinsic Value
The Intrinsic Value for each Graham Grade is calculated as follows.
a. Defensive Price (Graham Number)
The Intrinsic Value is calculated from the quantitative criteria (#6 and #7) for Defensive investment, and is popularly known as the Graham Number.
Note: Graham Numbers on Serenity are calculated using the average Earnings Per Share (EPS) of the past three years, just as Graham required.
b. Enterprising Price (Serenity Number)
Graham's quantitative criteria for Enterprising investment are the lower of 120% of Tangible Book Value Per Share (TBVPS), or a Price-to-Earnings (P/E) ratio of 10. With a derivation similar to the Graham Number, we get the following Intrinsic Value calculation.
c. NCAV Price (Net Current Asset Value / Net-Net)
Graham recommended the applicable Net Current Assets alone, deducting all prior claims and counting as Zero the fixed and other assets. The corresponding Intrinsic Value calculation is popularly known as Net Current Asset Value (NCAV) or Net-Net.
Note: Serenity does not use the misunderstood Benjamin Graham Formula to calculate intrinsic values.
2. Graham Grade
Every stock is assigned a Graham Grade as follows (preset links for Serenity's two Graham screeners are included).
The stock meets the qualitative criteria for Defensive investment (#1 to #5), and has a positive Defensive Price (Graham Number).
The stock is not Defensive but meets the qualitative criteria for Enterprising investment (#1 to #4), and has a positive Enterprising Price (Serenity Number).
c. NCAV (Net-Net)
The stock meets neither Defensive nor Enterprising criteria, but has a positive EPS in the Trailing 12 Months (TTM) and a positive NCAV Price (Net Current Asset Value / Net-Net).
3. Intrinsic Value(%)
Intrinsic Value ÷ Previous Close, expressed as a percentage. An Intrinsic Value(%) of 100% or more indicates that the stock's Intrinsic Value exceeds its price.
Graham Grade, Intrinsic Value and Intrinsic Value(%) — in combination — give a complete Graham assessment for a stock.
Note: Defensive and Enterprising grade stocks require an Intrinsic Value(%) of 70% based on current Bond Yields.
4. Graham Ratings
Each stock is additionally given the following Graham Ratings that can be used for customized filtering and stock selection. The Graham Ratings are defined such that they're better when higher, and that Graham's Defensive requirements default to 100%.
For reference, the minimum ratings required for each Graham Grade are given below.
|Graham Rating||Minimum Values|
|Size in Sales (100% ⇒ 500 Million)||100%||N/A||N/A|
|Current Assets ÷ [2 x Current Liabilities]||100%||75%||N/A|
|Net Current Assets ÷ Long Term Debt||100%||90%||N/A|
|Earnings Stability (100% ⇒ 10 Years)||100%||50%||N/A|
|Dividend Record (100% ⇒ 20 Years)||100%||5%||N/A|
|Earnings Growth (100% ⇒ 33% Growth)||100%||N/A||N/A|
|NCAV or Net-Net(%)||N/A||N/A||100%|
|[2 x Equity] ÷ Debt||100%||N/A||N/A|
|Size in Assets (100% ⇒ 250 Million)||100%||N/A||N/A|
 Criteria for Company Size have been adjusted for inflation.
 See Graham's notes on position sizing across stock grades.
 Optional rating for Public-Utilities and Financial Enterprises.
 70% when adjusted for bond yields and interest rates.
 May require customization for non-U.S. economies.
 Requires a positive EPS (TTM), the only non-annual data point.
 200% ⇒ 66% growth etc; years 1, 2, 3 and 10, 11, 12 used.
 Graham Number ÷ Previous Close, similar to Intrinsic Value(%).
 NCAV Price ÷ Previous Close; 150% ⇒ two-thirds NCAV.
