Five super falls -- one superball
Thanksgiving week wasn't a great one for stocks. Actually, it was downright miserable. The Dow Jones Industrial Average (INDEX: ^DJI) turned in its worst T-Day weekly performance since 1942, and investors in more than 5,600 companies ended the week poorer than they went into it. Many stocks -- including these five -- were literally decimated, losing 10% or more of their market cap in just a few short days. So what went wrong?

In a word: Europe. Fears that the Continent's debt crisis will destroy the global economy have markets in a panic. And because a slower economy needs less oil, natural gas, and coal to fuel its fires, energy traders are having a particularly hard time of things. The ranks of last week's losers run the gamut from Sandridge (oil) to Clean Energy and Westport Innovations (natural gas) to Walter Energy and Patriot Coal (er, coal.) Curiously, though, other investors seem to believe the world will eventually want to use some energy again. While the rest of the world is feverishly selling these stocks, CAPS members are giving them four- and five-star ratings. Are they right?

Call me a crazy optimist, but yes, I believe they are right. Whatever happens in Europe in the short term, I believe we'll eventually work through this crisis, and people will need oil, natural gas, and coal again. I believe companies in the energy industry will thrive. What's more, I see one company out of these five with a real chance of outperforming the market.

The bull case for Walter Energy
What puts Walter Energy ahead of all the rest -- and, in particular, above a certain natural-gas stock that many Fools adore? Some CAPS members think the answer is that Walter's a candidate for acquisition. Adaptivetrader, for example, says a CNBC analyst recently predicted a buyout for Walter. L0RDZ goes so far as to name a specific potential acquirer: BHP Billiton. JPAKolypse86 argues that "it's unlikely Walter will be bought," but even so, this CAPS participant thinks "This is still [a] $100 stock."

Me, I'm not going to go that far. But I still think that out of these five deeply damaged stocks, Walter has the most immediate chance for a bounceback, because it has one advantage the others lack: free cash flow. While each of Clean Energy, Westport, Sandridge, and Patriot is currently burning cash, Walter generated $290 million in free cash flow over the past year. And although that's not quite as big a number as we see claimed for net income on the company's income statement, it's enough to give Walter an attractively low price-to-free cash flow ratio of just 14.

Other numbers at Walter are similarly attractive. The company sells for a P/E of just 10.7, which is cheaper than you'll find at rival coal concerns such as Patriot or Alpha Natural Resources (NYSE: ANR), for example. Walter's also growing strongly, with most analysts predicting a 21% annual growth rate in profits over the long term.

Time to chime in
Ten times earnings, or even 14 times free cash flow -- these look like cheap multiples to pay for a 21% grower. That's the way I look at it, at least. But what do you think? Tell us on Motley Fool CAPS.
