As an investor, it pays to follow the cash. If you figure out how a company moves its money, you might eventually find some of that cash flowing into your pockets.
In this series, we'll highlight three big dogs in an industry, and compare their "cash king margins" over time, trying to determine which has the greatest likelihood of putting cash back in your pocket. After all, a company can pay dividends and buy back stock only after it's actually received cash -- not just when it books those accounting figments known as "profits."
The cash king margin
Looking at a company's cash flow statement can help you determine whether its free cash flow actually backs up its reported profit. Companies that can create 10% or more free cash flow from their revenue can be powerful compounding machines for your portfolio.
To find the cash king margin, divide the free cash flow from the cash flow statement by sales:
Cash king margin = Free cash flow / sales
Let's take McDonald's as an example. Over the last four quarters, the restaurateur generated $6.3 billion in operating cash flow. It invested about $2.1 billion in property, plant, and equipment. To calculate free cash flow, subtract McDonald's investment ($2.1 billion) from its operating cash flow ($6.3 billion). That leaves us with $4.2 billion in free cash flow, which the company can save for future expenditures or distribute to shareholders.
Taking McDonald's sales of $24.1 billion over the same period, we can figure that the company has a cash king margin of about 17% -- a nice high number. In other words, for every dollar of sales, McDonald's produces $0.17 in free cash.
Ideally, we'd like to see the cash king margin top 10%. The best blue chips can notch numbers greater than 20%, making them true cash dynamos. But some businesses, including many types of retailing, just can't sustain such margins.
We're also looking for companies that can consistently increase their margins over time, which indicates that their competitive position is improving. Erratic swings in margins could signal a deteriorating business, or perhaps some financial skullduggery; you'll have to dig deeper to discover the reason.
Four companies
Today, let's look at four players in drug retail:

CVS Caremark (NYSE: CVS )

Wal-Mart (NYSE: WMT )

1.5%
|
1.2%

None of these companies meets our 10% threshold for attractiveness, but Rite Aid has shown the kind of steady growth in its cash king margins over the past three years, amid very tough challenges. CVS and Walgreen have also increased their margins from three and five years ago, in large part by curtailing capital investment in the last four quarters. Wal-Mart too has slowed capex, and margins have improved from a half-decade ago.
The cash king margin can help you find highly profitable businesses, but it should only be the start of your search. The ratio does have its limits, especially for fast-growing small businesses. Many such companies reinvest all of their cash flow into growing the business, leaving them little or no free cash -- but that doesn't necessarily make them poor investments. You'll need to look closer to determine exactly how a company is using its cash.
Still, if you can cut through the earnings headlines to follow the cash instead, you might be on the path toward seriously great investments.
