Short interest moves among solar and alternative energy stocks were mixed during the two-week reporting period that ended on August 15. Of the companies we watch, short interest rose on three of the four solar stocks and two of the four alt energy stocks.

The solar industry is facing another glut of cells and modules, and a shakeout like the one that occurred about five years ago may be in the offing. The result, naturally, is more short interest in all these stocks, except the one that is being acquired.
