Welcome back to another Foolish review of the hottest stocks as ranked by Motley Fool CAPS. We're looking at the three best-performing industries over the past 30 days and your favorite long and short candidates in each.

Tune in, Fool. Cable TV systems suppliers such as TiVo (Nasdaq: TIVO) still rule our Foolish realm, up an average of 13.8% over the past 30 days. (Though, to be fair, that is down from the 23.2% 30-day gain these firms were enjoying last week.)

New faces populate the remainder of today's list. South African companies are up 12.4% since mid-February, while gold miners such as -- well, lookie here -- South Africa's Gold Fields (NYSE: GFI) are up 11% over the same period.

According to you, our Foolish readers, the best stocks in these industries to own now -- i.e., those with four or five of the maximum five stars in CAPS -- are:

My favorite this week is a growth stock that I liked at cheaper prices in December: Sasol. Little has changedĀ from the thesis I offered a few months ago:

The integrated energy player dabbles in a variety of areas, but its bread and butter is synthetic fuels. The company is also a leader in coal-to-liquid (CTL) technology, which could prove a boon if the U.S. decides to pour financial resources into building out such infrastructure.

And if it doesn't? Sasol's performance remains robust. Revenue, earnings from continuing operations, and net income were all up at least 14% in the latest quarter. Share buybacks juiced per-share earnings by 18%. And yet this company still trades for just 12 times current year profit estimates.

I can't see how that's fair, but I'm more interested in what you think. Would you buy Sasol at today's prices? Let us know what you think by signing up for CAPS today. It's 100% free to participate.
