Many investors turn to Benjamin Graham's so-called “Graham number” to calculate the fair price of a stock. The Graham number is √(22.5 * earnings per share * book value per share), which for QUALCOMM gives us a fair price of $42.56. In comparison, the stock’s market price is $123.59 per share. Therefore, QUALCOMM’s market price exceeds the upper bound that a prudent investor would pay for its shares by 190.39%.
The analysis shouldn't end here. The Graham number is often used in isolation, but in fact it is only one part of a check list for choosing defensive stocks that he laid out in Chapter 14 of The Intelligent Investor. The analysis requires us to look at the following fundamentals of QUALCOMM:
Sales Revenue Should Be No Less Than $500 million
For QUALCOMM, average sales revenue over the last 5 years has been $29,636,200,000, so in the context of the Graham analysis the stock has impressive sales revenue. Originally the threshold was $100 million, but since the book was published in the 1970s it's necessary to adjust the figure for inflation.
Current Assets Should Be at Least Twice Current Liabilities
We calculate QUALCOMM's current ratio by dividing its total current assets of $20,724,000,000 by its total current liabilities of $11,866,000,000. Current assets refer to company assets that can be transferred into cash within one year, such as accounts receivable, inventory, and liquid financial instruments. Current liabilities, on the other hand, refer to those that will come due within one year. QUALCOMM’s current assets outweigh its current liabilities by a factor of 1.75 only.
The Company’s Long-term Debt Should Not Exceed its Net Current Assets
This means that its ratio of debt to net current assets should be 1 or less. Since QUALCOMM’s debt ratio is 1.53, the company has too much debt. We calculate QUALCOMM’s debt to net current assets ratio by dividing its total long term of debt of $13,537,000,000 by its current assets minus total current liabilities.
The Stock Should Have a Positive Level of Retained Earnings Over Several Years
QUALCOMM had positive retained earnings from 2008 to 2022 with an average of $17,297,733,333. Retained earnings are the sum of the current and previous reporting periods' net asset amounts, minus all dividend payments.
There Should Be a Record of Uninterrupted Dividend Payments Over the Last 20 Years
QUALCOMM has offered a regular dividend since at least 2007. The company has returned a 2.43% dividend yield over the last 12 months.
A Minimum Increase of at Least One-third in Earnings per Share (EPS) Over the Past 10 Years
To determine QUALCOMM's EPS growth over time, we will average out its EPS for 2007, 2008, and 2009, which were $1.95, $0.20, and $0.50 respectively. This gives us an average of $0.88 for the period of 2007 to 2009. Next, we compare this value with the average EPS reported in 2020, 2021, and 2022, which were $2.58, $7.87, and $11.37, for an average of $7.27. Now we see that QUALCOMM's EPS growth was 726.14% during this period, which satisfies Ben Graham's requirement.
It may be trading far above its fair value and have significant debt, but QUALCOMM actually satisfies some of the criteria Benjamin Graham used for identifying for an undervalued stock because it has:
- impressive sales revenue
- an average current ratio
- positive retained earnings from 2008 to 2022
- a solid record of dividends
- EPS growth in excess of Graham's requirements
