On CAPS, 94% of the 596 members who have rated GT Solar believe the stock will outperform the S&P 500 going forward. These bulls include jpacheco14 and BillStacker.

A couple of months ago, jpacheco14 listed several of GT Solar's positives: "Large and growing backlog for the upcoming years, operates in the ever expanding markets of Asia, outstanding ROE, customers include companies with a very large market share in the field."

GT Solar even boasts a robust three-year average operating margin of 28%. That's much higher than that of competitors like Amtech (8.1%), Applied Materials (12.5%), and MEMC (11.4%).

CAPS member BillStacker elaborates on the GT Solar bull case:

Predicting more big orders on those sapphire furnaces coming soon. LEDs save energy and as the planet's demand for energy increases, the demand for LED will increase too. But so will the demand for solar! SOLR's solar biz is going to turn into the icing going forward though. As more players (like TSM) decide to get in the LED business, who is going to be supplying their manufacturing equipment? GT Advanced Technologies are establishing themselves as leaders here.
