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 TiVo (Nasdaq: TIVO) 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.

TiVo has negative P/E and EV/FCF ratios over the trailing 12 months. If we stretch and compare current valuations to the five-year averages for earnings and free cash flow, TiVo has a negative P/E ratio and a five-year EV/FCF ratio of 3,806.5.

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

TiVo is zero for four on hitting the ideal targets, but let's see how it compares against some competitors and industry mates.

Numerically, we've seen how TiVo's 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, TiVo's net income margin has ranged from -23.2% to 38.3%. In that same time frame, unlevered free cash flow margin has ranged from -14.4% to 42.2%.

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

Additionally, over the last five years, TiVo has tallied up 1 year of positive earnings and 2 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 to similar numbers from a company's closest rivals.

Let's start by seeing what this company's done over the past five years. In that time period, TiVo has had some losses which render its EPS growth rates meaningless, but Wall Street's analysts expect future growth rates of 33.5%.

Here's how TiVo compares to its peers for trailing five-year growth (the growth rates are meaningless for TiVo and DirecTV):

And here's how it measures up with regard to the growth analysts expect over the next five years:

The bottom line
The pile of numbers we've plowed through has shown us how cheap shares of TiVo 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.

For a technology company like TiVo, the numbers can look ugly -- even if the company is a good investment. For TiVo, a potential investor should look at the value of its patents as part of the due diligence process. Then continue your due diligence process until you're confident that the initial numbers aren't lying to you.
