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, stocks under the thumb of Venezuelan president Hugo Chavez topped the hotheads. But not this week. This time, solar stocks are hotter than the big orange ball in the sky from which they derive their returns. As a group, the sun worshippers are up 23.5% over the past 30 days.

Who are the other hotties? Have a look:

  • The Latin leaders from Venezuela are, as a group, up 22.1% over the last 30 days.
  • Glowing brightly in the third spot are the uranium miners, whose stocks are, as a group, up 21.1% over the last 30 days.
