Suntech Power (STP) is taking a post-earnings plunge, as traders pan the company's third-quarter report.

Wednesday morning, Suntech said its third-quarter profit climbed 11% to $33.1 million, or 18 cents per American depositary share (ADS), while revenue rose 57% to $743.7 million. Gross margin for the quarter contracted to 16.4% from 17.8%, due to lower selling prices.

China-based Suntech Power Holdings Co. (NYSE: STP) is one of China's top stocks. The country's largest solar panel maker recently took steps to increase its hold on the Chinese solar market when it reached an agreement with a unit of China Huadian Corp. to develop 500MW of solar projects in China.

The collaboration between Suntech and China Huadian New Energy Development Co. could include some of the 1.8 gigawatts of Chinese projects Suntech recently announced. According to the company, the projects resulting from those agreements could be installed between 2010 and 2012. This deal means a solid pipeline of earnings for the solar maker, and that could translate into solid earnings going forward.

Suntech Power Holdings (NYSE: STP) has priced its follow-on public offering at $12.50 per share. The company will be issuing 20 million American Depositary Shares to raise a total of $250 million. The stock is being issued under an existing shelf registration filing.

Underwriters UBS (NYSE: UBS), Goldman Sachs (NYSE: GS) and Deutsche Bank (NYSE: DB) have an option to purchase up to 3 million to cover any over-allotment.

China-based Suntech Power Holdings (NYSE: STP) is slated to report its third-quarter earnings results ahead of the opening bell tomorrow, and the solar stock looks particularly vulnerable to a post-report drubbing. Sector peer JA Solar (NASDAQ: JASO) fell to an all-time low last week after offering a weak outlook, while Trina Solar (NYSE: TSL) today lowered its revenue forecast for 2008.

Currently, First Call reports that analysts are expecting STP to report a quarterly profit of 42 cents per American depositary receipt. Suntech has a respectable history in the earnings spotlight, having exceeded the Street's forecast in three out of its past four reports.

On the plus side, it seems as though many brokerage firms have already downwardly revised their expectations for STP. There have been 10 cuts to the firm's average 2008 earnings-per-share estimates, compared to just two increases.

Plus, several analysts have issued bearish notes on Suntech in the past few weeks: Jefferies & Co. cut its price target on November 17; JPMorgan Chase cut the stock from "neutral" to "underweight" and lowered its price target on November 16; Raymond James downgraded STP from "strong buy" to "outperform" on November 13, the same day that AmTech Research slashed its price target; and Deutsche Bank cut the stock from "hold" to "sell" on November 10.

Over 32 years, the portfolio in The Oberweis Report has returned an average gain of 21.2% a year vs. 7.9% for the S&P 500. Here, money manager and newsletter advisor Jim Oberweis, Jr. looks at Suntech Power Holdings Ltd. (NYSE: STP).

"Long-term results notwithstanding, 2008 has been humbling, to say the least. No other year in our history has been as challenging.

"But in our experience, the most favorable buying opportunities tend to fall after a period in which the market has not performed well.

"Although year-by-year results can be volatile, disciplined investors who remain fully invested in a portfolio of high-growth equities selected using our methodology have historically achieved an exceptional average rate of return over long periods of time.

"Suntech Power Holdings Co., Ltd is one of the leading solar energy companies in the world as measured by production output of photovoltaic, or PV, cells, with leading positions in key solar markets such as Germany and Spain.

Rival home improvement chains Home Depot Inc. (NYSE: HD) and Lowe's Companies Inc. (NYSE: LOW) are scheduled to report quarterly results this week. Not surprisingly, given the ongoing housing slump, analysts surveyed by Thomson Financial on average expect both companies to post earnings lower than in the same period a year ago. For Home Depot, that's 61 cents per share, down 20.8%, and for Lowe's, 56 cents per share, down 16.4%. Meanwhile, cabinet maker American Woodmark Corp. (NASDAQ: AMWD), for whom Home Depot and Lowe's are major distributors, is also expected to report lower earnings: 11 cents per share, down 67.6%.

The presidential campaigns have prompted much discussion of energy policy and alternative energy sources. Some solar-energy-related concerns are scheduled to report this week, and expectations seem to be high. Trina Solar Ltd. (NYSE: TSL) is expected to report 81 cents per share earnings, up 67.9%; ReneSola Ltd. (NYSE: SOL) is expected to post earnings of 32 cents per share, up 62.5%; and Suntech Power Holdings Co. (NYSE: STP) is expected to have earnings of 32 cents per share, up 21.9%. Even China Sunergy Co. Ltd. (NASDAQ: CSUN) is expected to have swung to a profit of 3 cents per share, from a per-share loss of 14 cents a year ago.

Minyanville's Sean Udall dares to share the kind of keen insight and actionable information you won't find in any prospectus. Here he answers a reader's burning question about "green" stocks. For more original thought, visit www.minyanville.com.

Professor Udall,

Do you have any opinions on Zoltek Companies, Inc. (NASDAQ: ZOLT)? My wife wants me to buy everything "green". Her last "green" company idea was General Electric (NYSE: GE). I know, right? I bought a little just to quiet the noise level. I'm into a little SunPower (NASDAQ: SPWR) and Evergreen Solar (NASDAQ: ESLR). Does Zoltek have legs?

Thanks,

Minyan L.

First, that's hysterical. Second, a word of caution: Going all green, or all of any one thing, is something I'd never advocate. If you do, you do so at your own risk, as nothing in the market is ever as obvious as it seems, especially when it seems totally obvious.
