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 MercadoLibre gives us a fair price of $39.0. In comparison, the stock’s market price is $1316.37 per share. Therefore, MercadoLibre’s market price exceeds the upper bound that a prudent investor would pay for its shares by 3274.9%.

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 MercadoLibre:

*Sales Revenue Should Be No Less Than $500 million*

For MercadoLibre, average sales revenue over the last 4 years has been $5,969,047,000, 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 MercadoLibre's current ratio by dividing its total current assets of $10,953,000,000 by its total current liabilities of $8,562,000,000. 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. MercadoLibre’s current assets outweigh its current liabilities by a factor of 1.3 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 MercadoLibre’s debt ratio is -2.7, the company has negative current asset / liability balance. We calculate MercadoLibre’s debt to net current assets ratio by dividing its total long term of debt of $2,590,000,000 by its current assets minus total liabilities of $11,909,000,000.

*The Stock Should Have a Positive Level of Retained Earnings Over Several Years*

MercadoLibre had positive retained earnings from 2009 to 2022 with an average of $402,180,554. 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*

We have no record of MercadoLibre offering a regular dividend within the last twenty years.

*A Minimum Increase of at Least One-third in Earnings per Share (EPS) Over the Past 10 Years*

We are going to compare MercadoLibre's earnings per share averages from the two 'bookends' of the 15 year period for which we have data. The first bookend comprises the years 2008, 2009, and 2010, whose EPS values of $0.42, $0.26, and $1.27 average out to $0.65. Next we look at the years 2020, 2021, and 2022, whose values of $-1.02, $-0.92, and $3.25 average out to $0.44. The growth rate between the two averages does not meet Graham's standard since it is -32.31%.

Despite having an acceptable dividend record and positive retained earnings, MercadoLibre does not have the profile of a defensive stock according to Benjamin Graham's criteria because in addition to trading far above its fair value, it has:

- an average current ratio
- a negative current asset to liability balance
- decreasing earnings per share
