Graham's Stock Grades
"By far the best book about investing ever written... a sound intellectual framework for making [investment] decisions."
Graham's Stock Grades
Benjamin 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.
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.
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: Criterion #1 requires adjustment for Inflation and defaults to 500 million on GrahamValue.
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.
GrahamValue 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. Graham's own recommendation was closer to 30 and 3.3%, but open-ended.
Note: For criterion #4, GrahamValue compares last year's earnings to that of 4 years ago.
3. NCAV (Net-Net)
Net Current Asset Value is Graham's most well-known category of stocks, but 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.
Note: Apart from the 2nd criterion above for an EPS (TTM), Graham analyses are done almost exclusively with annual data.

GrahamValue 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 №)
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 GrahamValue are calculated using the average EPS of the past three years, just as Graham required.
b. Enterprising Price (Serenity №)
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.
Note: This extrapolated derivation is the only deviation that GrahamValue makes from Graham's published principles.
c. NCAV Price (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 / Net-Net).
Note: GrahamValue 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 GrahamValue's two Graham screeners are included along with each Graham Grade.
The stock meets the qualitative criteria for Defensive investment (#1 to #5), and has a positive Defensive Price (Graham №).
The stock is not Defensive but meets the qualitative criteria for Enterprising investment (#1 to #4), and has a positive Enterprising Price (Serenity №).
c. NCAV (Net-Net)
The stock meets neither Defensive nor Enterprising criteria, but has a positive EPS (TTM) and a positive NCAV Price (Net-Net).
3. Intrinsic Value(%)
Intrinsic Value(%) is 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 unadjusted Graham assessment for a stock.
Intrinsic Value(%) measures what Graham defined as the Margin of Safety.
Note: Defensive and Enterprising grade stocks require their Intrinsic Value(%) adjusted for current Interest Rates.
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|

 Requires adjustment for Inflation; defaults 500M and 250M.
 Requires adjustment for Bond Yields and Interest Rates.
 Requires adjustment for non-U.S. Interest Rates and Inflation.
 Requires a positive EPS (TTM), the only non-annual figure.
 Requires adjustment for Inflation; uses three-year averages.
 Graham Number ÷ Previous Close, similar to Intrinsic Value(%).
 NCAV Price ÷ Previous Close, similar to Intrinsic Value(%).
 Similar to Upside, and measures the Margin of Safety.
