Every day, the sun rises on Wall Street, and a plethora of professional analysts wake to issue new opinions on stocks. Here at the Fool, we examine some of these picks -- and the track record of the firm behind them -- so individuals can make better investing decisions.

In addition to following professional banks, anyone can use Motley Fool CAPS to monitor the collective opinions of more than 105,000 investors, many of whom demonstrate better investing insight than published analysts do.

Enough top-performing CAPS investors have turned bullish on Trina Solar (NYSE: TSL) in the past few weeks to upgrade it from the subpar two-star rank it has held for months to a more admirable three stars. More than 850 investors have weighed in with an opinion on Trina Solar, with many of them offering analysis and commentary on the recent optimism.

On the supply side, Trina Solar has improved its long-term raw-material risk by cutting deals with Silfab in late April and more recently with DTK Industries that will diversify its polysilicon supplier base and buffer the company from potential shortfalls of other suppliers over the next several years.

Another solar player has received an upgrade in CAPS as well -- three-star-ranked Canadian Solar (Nasdaq: CSIQ), whose impressive quarterly results helped catapult the entire solar sector higher and push up players such as First Solar (Nasdaq: FSLR) and Solarfun Power (Nasdaq: SOLF).

With all of the giddiness around solar power these days, many CAPS investors also take comfort in a more reasonable valuation for Trina Solar. With a 2008 forward earnings multiple of 15, Trina potentially offers more bang for the buck than more richly valued companies such as Suntech Power (NYSE: STP) and LDK Solar (NYSE: LDK), with forward multiples of 30 and 24, respectively. Altogether, 80% of the 855 investors now rating Trina Solar believe it will beat the S&P going forward.

To see what the very best CAPS analysts are saying now about Trina Solar -- as well as other winning stocks they are picking -- head on over to CAPS and have a look. The community research and resources in CAPS are totally free, unlike analyst opinions reserved for paying clients.
