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 MEMC Electronic Materials (NYS: WFR) 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.
MEMC has a negative P/E ratio and a negative EV/FCF ratio over the trailing 12 months. If we stretch and compare current valuations to the five-year averages for earnings and free cash flow, MEMC has a P/E ratio of 4.5 and a negative EV/FCF ratio.
A positive one-year ratio under 10 for both metrics is ideal (at least in my opinion). For a five-year metric, under 20 is ideal.
MEMC 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 MEMC'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, MEMC's net income margin has ranged from -1.4% to 32.8%. In that same time frame, unlevered free cash flow margin has ranged from -24.1% to 33.6%.
How do those figures compare with those of the company's peers? See for yourself:

Additionally, over the last five years, MEMC has tallied up four years of positive earnings and two 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 willoverpay 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. Due to losses, the trailing EPS growth rates for MEMC and First Solar aren't meaningful, but here's how their peers did:

And here's how it measures up with regard to the growth analysts expect over the next five years (note: my data provider doesn't list any analyst estimates for Amkor, but Yahoo! Finance puts it at 10%):

The bottom line
The pile of numbers we've plowed through has shown us the price multiples shares of MEMC 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 negative P/E ratio and we see quite a bit of earnings and free cash flow volatility. Not surprising for a company tied to the solar industry. Its five-year P/E ratio is quite low, but it's currently running negative earnings. Clearly, a lot depends on the macro supply and demand factors in solar. Read about the latest here.
