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.

Cable TV systems, after a one-week hiatus, are once again atop the charts. Their 16.3% average return easily bests the 12.2% gain put up by Arkansas residents such as Wal-Mart (NYSE: WMT) and Tyson Foods.

This week's third-place finisher -- residential construction specialists -- tells me that investors have gone back to the garbage bin in search of worthy castoffs. Walter Industries and its lower-rated peers are up an average of 10.3% since early March.

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 stock among today's contenders is U.K. media maven British Sky Broadcasting. CAPS investor drbennet best described the thesis last February, I think. Quoting:

As more and more people upgrade to Sky or SkyHD profit per customer will increase. also the launch of Sky Broadband should eventually start build further revenue per customer as they can resolve the perceived customer services issues.

Others, such as stocksshmocks, say that British Sky Broadcasting is a better choice for your portfolio than Comcast (Nasdaq: CMCSA). Numbers bear this out: British Sky has earned a 21.8% return on invested capital over the trailing 12 months, while Comcast has earned just 4.8%.

Then there's the dividend. Comcast yields less than half the 2.9% British Sky pays out. Which would you rather have? Seriously, I'm asking. Would you buy British Sky Broadcasting at today's prices? Let us know what you think by signing up for CAPS today. It's 100% free to participate.
