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, makers of medical diagnostic equipment topped the hotheads. Not this week. LED lighting manufacturers, such as Cree (NASDAQ:CREE), have become a beacon for investors, with a 24.5% average gain for the group over the past 30 days.

Who are the other hotties? Have a look:

  • Subrpime lenders have climbed out of the basement and into the second spot, returning 22.5% as a group since the middle of May.
  • And in third is a smelly new entrant: fertilizer makers, which are up 20.4% as a group over the past month.
