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 week, makers of personal digital assistants or their components were booting up the big returns. But not this week. This time, solar stocks are shining as bright as the sun they depend on for returns. Stocks in this sector are, as a group, up 10.3% over the last 30 days.

Who are the other hotties? Have a look:

  • Second best are stocks from Ohio. Dayton-based NCR (NYSE:NCR) and its Buckeye buddies are, as a group, up 9.8% over the last 30 days.
  • Third best, for the third straight week, are the uranium producers. Digging for radioactive gold has stocks in this sector, as a group, up 9.2% over the last 30 days.
