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 * 5 year average earnings per share * book value per share), which for Nucor gives us a fair price of $184.03. In comparison, the stock’s market price is $155.63 per share. Therefore, Nucor’s market price is lower than what a prudent investor would pay for its shares by -15.4%.
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 Nucor:
Sales Revenue Should Be No Less Than $500 million
For Nucor, average sales revenue over the last 5 years has been $50.9 Billion, 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 Nucor's current ratio by dividing its total current assets of $16.39 Billion by its total current liabilities of $4.59 Billion. 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. In Nucor’s case, current assets outweigh current liabilities by a factor of 3.6.
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 Nucor’s debt ratio is 2.1, the company has too much debt because its long term debt to net current asset ratio is 2.1. We calculate Nucor’s debt to net current assets ratio by dividing its total long term of debt of $6.65 Billion by its current assets minus total liabilities of $13.22 Billion.
The Stock Should Have a Positive Level of Retained Earnings Over Several Years
Nucor had good record of retained earnings with an average of $11.12 Billion. Retained earnings are the sum of the current and previous reporting periods' net asset amounts, minus all dividend payments. It's a similar metric to free cash flow, with the difference that retained earnings are accounted for on an accrual basis.
There Should Be a Record of Uninterrupted Dividend Payments Over the Last 20 Years
Nucor has offered a regular dividend since at least 2007. The company has returned an average dividend yield of 2.1% over the last five years.
A Minimum Increase of at Least One-third in Earnings per Share (EPS) Over the Past 10 Years
To determine Nucor's EPS growth over time, we will average out its EPS for 2007, 2008, and 2009, which were $4.94, $5.98, and $0.18 respectively. This gives us an average of $3.70 for the period of 2007 to 2009. Next, we compare this value with the average EPS reported in 2021, 2022, and 2023, which were $7.97, $4.89, and $18.00, for an average of $10.29. Now we see that Nucor's EPS growth was 178.11% during this period, which satisfies Ben Graham's requirement.
Nucor meets most of Benjamin Graham's criteria for an undervalued stock because in addition to trading far below fair value, it has:
- impressive sales revenue
- an excellent current ratio of 3.57
- too much debt because its long term debt to net current asset ratio is 2.1
- good record of retained earnings
- a solid record of dividends
- a strong EPS growth trend
