Over on CAPS, fully 342 of the 366 All-Star members who have rated MEMC -- some 93% -- believe the stock will outperform the S&P 500 going forward. These bulls include marc64 and angus118. In May, marc64 wrote:

[MEMC is a] real company, turning great profits, growing fast and sitting on a bunch of cash. The current [price-to-earnings ratio] does not reflect its growth. ... WFR looks like it's needing governments' help less and less. What's not to like?

A pitch from angus118 a day later agreed with that bullish sentiment, highlighting the stock as a powerful "poly play":

The rise of oil prices in recent years has led to increased demand for solar energy, which in turn has created a run-up in silicon prices that makes oil's climb look modest. In 2000 a kilogram of "polysilicon" could have been yours for $9. By the time of my first column on MEMC nearly four years ago, poly was up to about $30 a kilogram. By last November's column it had soared to $200. Now it's more than twice as expensive. That has been a boon for MEMC, which unlike many of its competitors makes most of its poly.
