7 Stocks Raising Another Red Flag

While high-frequency trades spat out by computers may appear to drive today's market, there is still room for investors to earn fat returns through old-fashioned fundamental analysis.

Beginning in 2002, activist value investor Bill Ackman became convinced that the bond insurers were much riskier than their triple-A rating suggested. When the extent of their exposure to structured mortgage securities came to light during the credit crisis, the stocks imploded, and Ackman's short positions turned into huge winners.

A showman and a serious analyst
Although he is primarily known for his brash tactics, Ackman is first and foremost a deeply inquisitive security analyst. On MBIA alone, he amassed 140,000 pages in documentation in the course of his research. One of Ackman's favorite investing books is Thornton O'Glove's Quality of Earnings, a primer on a rigorous, skeptical approach to financial analysis that enables investors to identify "time bomb" stocks for protection -- and profit.

All serious investors should put Quality of Earnings on their reading list. In the meantime, let me give you a taste of what O'Glove calls "the best method I have ever discovered of predicting future downwards earnings revisions of Wall Street security analysts." This method covers two balance sheet accounts: accounts receivable and inventory.

In this article, I'll focus on the former.

  • What are accounts receivable?

When a company has delivered goods and services for which it has not yet been paid, the sums it is owed go onto the balance sheet under accounts receivable.

  • What can accounts receivable tell you?

As O'Glove points out, if accounts receivable are growing faster than sales, this could indicate the company is granting its customers more favorable payment terms or that it is having a hard time collecting what it is owed -- neither of which is a positive sign for the business. Another possible explanation is that the company is offering aggressive incentives to goose sales, which hurts profits while providing only a temporary boost to the top line.

Say it ain't DSO
An easy way to track the growth of accounts receivable relative to sales is a metric called days sales outstanding (DSO), which is the amount in accounts receivable expressed as a multiple of the company's daily revenue. By definition, when the DSO increases from one period to another, accounts receivable growth is outpacing sales growth. The following table contains seven stocks from the Russell 1000 index that exhibited a high increase in their DSO over the most recent four quarters:

Now, let me be very explicit that these are not short recommendations. Statistical screens are powerful tools for sifting through large amounts of data; however, they are blunt instruments when it comes to analyzing individual stocks. Screens highlight "high-probability" pockets in the market, but you need to conduct detailed company-specific analysis in order to confirm that a specific result isn't a false positive.

Good businesses, bad surprises?
Cisco Systems, for example, is a terrific business that I have highlighted as a potential buy recently for its low multiple and expanding business.

Nonetheless, even great companies aren't immune to negative earnings surprises that are predictable with a careful analysis of earnings quality. One must perform adequate follow-up research to determine for each specific company whether the DSO is truly a harbinger of an imminent problem or not.

    So the Fool has us in Hasboro. Now you raise this potential downward pressure. Do we sit on this stock and get whacked or do we take our profits?

    I would be happier to have read a more complete analysis of Cisco. If you have been recommending the stock, wouldn't it be the responsible thing to put this information into context and compare others in the same industry. Is the economy, Cisco, the way we live today or is Cisco in trouble?

    This is simply an analysis of where these stocks are headed in the short term. It's not all that surprising seeing as there has been a slowdown from rapid growth from the doldrums of the recession to what is now looking like low or no growth for a while. Sell Hasbro if you like but as the Stock Advisor says - they have franchises gaining steam that someone like Disney may just chomp at the bits for IF they're stock reaches an attractive takeover price. If you sell, you take your profits now. If you wait, you continue to get a solid dividend while the stock plays like a yo-yo and potentially miss out on a big payday if it gets taken over.

    OKAY. . . so how does the MF membership determine DSO. I don't ever recall seeing that info in looking over fundamental stats. I am not sure whether the explanation above included a calculation 'method'. . ."the amount in accounts receivable expressed as a multiple of the company's daily revenue." ???

    Thanks for your question. Here is the explicit formula for Days' Sales Outstanding (DSO):

    DSO = (Average Accounts Receivable Over Period/ Total Revenue During Period) * Number of Days in Period

    The Accounts Receivable figures can be found on the balance sheet and the revenue figures are on the income statement.

    I think you are all missing the point ... this is an advertisement! They did not even bother to go into the calculation of the metric for inventory! While the A/R metric is a good indicator, you need to look at the whole picture. Maybe only when both metrics are showing negative implications should you take action. I.E. The metrics are positively coorelated.

    Is it likely that the lack of the market for account receivable securitization is the primary cause of these DSO increases? I am pretty sure that's the case for Hasboro for example.

    When I think of Seagate (and Western Digital) I think of hard drives. I may have a multi-terabyte backup drive in a few years, but I know my computer will have a solid state drive, and most likely one which I can swap between computers. So will everyone else's. Food for Foolish thought.
