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, Greek stocks were tanned, toned, and covered in cash. Today, they're wrinkled. They've been replaced by makers of organic light-emitting diodes, which are up an average of 28.4% over the past 30 days.

Our other hotheads are decidedly lower-tech. Stocks from Nevada rank second, up 19.7% since mid-July. Manufactured-housing stocks are third, with an 18.4% average return over the past month.
