On CAPS, 92% of the 448 members who have rated GT Solar believe the stock will outperform the S&P 500 going forward. These bulls include woodhaven1965 and Lumiere33.

Late last year, CAPS member woodhaven1965 tapped the stock as a bright selection:

Solar energy sector will grow and [GT Solar] is a cost-effective supplier of the raw building blocks of solar technologies. Like to bet on the suppliers in growing industries rather than the front line product creators (where competition can really kill quickly). If industry grows, there will be room for numerous quality suppliers.

GT Solar's debtless balance sheet and exciting growth prospects support its four-star CAPS status. Over the next five years, GT Solar is expected to grow its bottom line (50% per annum) at a faster pace than rivals Amtech (35%), Applied Materials (14%), and MEMC (18%), as well as solar panel plays such as First Solar (Nasdaq: FSLR) (24%) and Yingli Green Energy (NYSE: YGE) (29%).

CAPS member Lumiere33 lists more of the stock's positives:

[GT Solar] is currently entrenched in three rapidly growing markets: polysilicon production, polycrystalline PV, and now LED (sapphire crystal substrate technologies). It is a growing profitable company with great margins, no debt, and a worldwide customer base.
