Numbers can lie -- but they're the best first step in determining whether a stock is a buy. In this series, we use some carefully chosen metrics to size up a stock's true value based on the following clues:

  • The current price multiples
  • The consistency of past earnings and cash flow
  • How much growth we can expect

Let's see what those numbers can tell us about how cheap upscale fashion retailer Saks (NYSE: SKS) might be.

The current price multiples
First, we'll look at most investors' favorite metric: the P/E ratio. It divides the company's share price by its earnings per share (EPS) -- the lower, the better.

Then, we'll take things up a notch with a more advanced metric: enterprise value to unlevered free cash flow. This divides the company's enterprise value (basically, its market cap plus its debt, minus its cash) by its unlevered free cash flow (its free cash flow, adding back the interest payments on its debt). Like the P/E, the lower this number is, the better.

Analysts argue about which is more important -- earnings or cash flow. Who cares? A good buy ideally has low multiples on both.

Saks has a negative P/E ratio, but has an EV/FCF ratio of 11.3 over the trailing 12 months. If we stretch and compare current valuations with the five-year averages for earnings and free cash flow, Saks still has a negative P/E ratio and a five-year EV/FCF ratio of 75.8.

A one-year ratio under 10 for both metrics is ideal. For a five-year metric, under 20 is ideal.

Saks is 0 for 4 on hitting the ideal targets, but let's see how it compares against some competitors and industry mates.

Numerically, we've seen how Saks' valuation rates on both an absolute and relative basis. Next, let's examine ...

The consistency of past earnings and cash flow
An ideal company will be consistently strong in its earnings and cash flow generation.

In the past five years, Saks' net income margin has ranged from minus 7.5% to plus 1.4%. In that same time, unlevered free cash flow margin has ranged from minus 4.2% to plus 6.9%.

How do those figures compare with those of the company's peers? See for yourself:

Also, over the past five years, Saks has tallied up three years of positive earnings and three years of positive free cash flow.

Next, let's figure out ...

How much growth we can expect
Analysts tend to comically overstate their five-year growth estimates. If you accept them at face value, you will overpay for stocks. But while you should definitely take the analysts' prognostications with a grain of salt, they can still provide a useful starting point when compared with similar numbers from a company's closest rivals.

Let's start by seeing what this company has done over the past five years. Unfortunately, because of its unprofitability, a five-year growth rate doesn't tell us anything. On the other hand, Wall Street's analysts expect future growth rates of 9.6%.

Here's how Saks' peers have done on trailing five-year growth:

The bottom line
The pile of numbers we've plowed through has shown us how cheap shares of Saks are trading, how consistent its performance has been, and what kind of growth profile it has -- both on an absolute and a relative basis.

The more consistent a company's performance has been and the more growth we can expect, the more we should be willing to pay. We've gone well beyond looking at a negative P/E ratio.

By the numbers, Saks doesn't look that compelling. Diving in a little further, I see very spotty earnings from operations in the past few years – even factoring in the tough times. By the numbers, Macy's is the competitor I'd look into further. Its five-year cash flows look a lot better than its earnings because earnings have been impaired by some non-cash restructuring charges.

If you find any of these numbers compelling, don't stop. Continue your due diligence process until you're confident that the initial numbers aren't lying to you.
