A lot of the solar stocks plunged today. Im wondering what Goldman Sach's angle is on this one. Are they loading up as they watch the solar stocks drift down? Everytime I have seen Goldman upgrade or downgrade a stock then something fishy happens... Out of the Gate: Solarfun plunges, erasing gains Thursday May 22, 10:25 am ET Solarfun plunges after Goldman cuts to 'Sell,' saying shares are overpriced after run-up NEW YORK (AP) -- Shares of Solarfun Power Holdings Co. fell sharply at market open on Thursday after a Goldman analyst downgraded the China-based solar cell maker to "Sell," saying the stock is overpriced after a recent surge in value. ADVERTISEMENT The stock plunged $3.18, or 12 percent, to $23.32, erasing most of the stock's gains from the past several days. Cheryl Tang cut Solarfun's rating from "Neutral" in a note to investors Thursday, highlighting the recent gains. Shares of Solarfun are up more than 75 percent since closing May 12 at $14.94. Tang attributed the run-up to high expectations ahead of the company's first-quarter earnings report, which came in better-than-expected on Wednesday. The stock's "premium valuation" is now unwarranted, she said, especially as solar wafer prices hold steady and pressure the company's earnings in the coming quarters. Tang raised her price target to $20 from $17, implying she expects the stock to fall 25 percent in the next 12 months. She also raised her earnings estimates for the next several years to reflect the company's first-quarter results. Early Wednesday, Solarfun posted a first-quarter profit of $15.3 million, or 32 cents per ADR, handily beating Wall Street estimates of 16 cents per ADR, according to a poll by Thomson Financial. Shares have traded between $8.22 and $40.19 in the last 52 weeks.
