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.

Last time, fertilizer makers had shed the stink. They're still smelling sweet today, but a 29.3% average return was only good for third place. Yowza.

So who's in first? The sun worshippers. Solar stocks are up an average of 30.5% over the past 30 days. Second place, meanwhile, is just dry. And I don't mean boring; I mean dry. Shippers of dry bulk goods are, on average, up 29.7% since late August.
