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 expensive or cheap Sigma Designs
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 -- 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.
Sigma Designs has a P/E ratio of 43.0 and an EV/FCF ratio of 10.5 over the trailing 12 months. If we stretch and compare current valuations to the five-year averages for earnings and free cash flow, Sigma Designs has a P/E ratio of 17.2 and a five-year EV/FCF ratio of 10.0.
A positive one-year ratio under 10 for both metrics is ideal. For a five-year metric, under 20 is ideal.
Sigma Designs has a mixed performance in hitting the ideal targets, but let's see how it compares against some competitors and industry mates.

Numerically, we've seen how Sigma Designs' 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, Sigma Designs' net income margin has ranged from 1.2% to 31.7%. In that same time frame, unlevered free cash flow margin has ranged from 6% to 21.6%.
How do those figures compare with those of the company's peers? See for yourself:

Additionally, over the last five years, Sigma Designs has tallied up five years of positive earnings and five years of positive free cash flow.

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. Because of a prior loss, Sigma's trailing growth rate isn't meaningful (it is notable that it swung to a profit, though). Meanwhile, Wall Street's analysts expect future growth rates of 16%.

The bottom line
The pile of numbers we've plowed through has shown us the price multiples shares of Sigma Designs are trading at, the volatility of its operational performance, 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 43.0 P/E ratio, and we see that Sigma's EV/FCF ratios make it look a lot cheaper. This is due both to stronger free cash flows than earnings and Sigma's net cash balance. If you believe in Sigma's growth prospects, it's worth a second look based on the initial numbers. If you do find Sigma Designs' numbers or story compelling, don't stop. Continue your due diligence process until you're confident one way or the other.
