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.

JA Solar (NASDAQ: JASO) blew its quarter and lowered guidance, and now the group is under pressure.

I don't think I've ever written a positive word on JASO as they are in the middle tier, essentially a jobber for the solar space. The company make various feedstock products to the final product makers, while being dependent on the core technology and "root" feedstock polysilicon from the likes of LDK Solar (NYSE: LDK) and MEMC Electronics (NYSE: WFR). So it has a timing issue and margin compression issue. The company is facing lower final pricing of their products while having locked in longer term "commodity" pricing at higher prices. So its raw costs are not falling as fast as its own pricing.

The poly guys mentioned above and companies like Sun Power (NASDAQ: SPWRA), First Solar (NASDAQ: FSLR) and Suntech Power (NYSE: STP) don't face these pressures as intensely, though that may not matter much today. STP reports on the 20th this month and I think it will give a clearer picture of the space. Meanwhile SPWRA keeps closing significant deals and FSLR reported the best and has little if any of the funding concerns. So for the leaders, it's a question of how low do they go before the long term positives catch up. Meanwhile, a few of the smaller shops like JASO are in a race against the credit crunch because they need to be able to renegotiate some of their longer-term input costs.

LDK and WFR are still companies that I feel are uniquely positioned, as both have a partial oligopoly status as polysilicon suppliers. In the $15's and lower, it's getting to the point where I may again trade around my core position and look for that beta pop on any significant Naz bounce. Also, this stock could move 50% higher and still be exceedingly cheap on almost any value criteria.

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.

Suntech Power Holdings (NYSE: STP) shares are trading higher today on reports that the Japanese Ministry of Economy, Trade and Industry (METI) is considering a resumption of subsidies for solar panel makers beginning next year to maintain its lead in the industry. METI will be discussing subsidies at its meeting this week. This could be a good sign for the solar industry and STP. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on GIS.

After hitting a one-year high of $90.00 in January, the stock hit a one-year low of $28.19 in March. STP opened this morning at $42.01. So far today the stock has hit a low of $41.12 and a high of $42.69. As of 12:35, STP is trading at $41.85, up 0.54 (1.3%). The chart for GIS looks bearish but improving slightly, while S&P gives the stock a positive 4 STARS (out of 5) buy rating.

For a bullish hedged play on this stock, I would consider an August bull-put credit spread below the $30 range. A bull-put credit spread is an options position that combines the purchase and sale of put options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make a 7.5% return in just two months as long as STP is above $30 at August expiration. STP would have to fall by more than 28% before we would start to lose money. Learn more about this type of trade here.

STP hasn't been below $30 since March and has shown support around $38 recently. This trade could be risky if the company's earnings (due out in early August) disappoint, but even if that happens, this position could be protected by the support the stock might find between $35 and $40, where it bounced over the past month.

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.

"Oil is setting the stage for a big rally in alternative energy," says Eric Roseman, resources expert and editor of Commodity Trend Alert. Here's a look at two stocks poised to benefit from this trend.

"A surging oil price is extremely bullish for alternative energy. Over the last 12 months, as oil prices have doubled, uranium and solar energy stocks have crashed.

"These sectors have declined because sub-prime has taken everything to the basement until recently - not because solar energy or uranium are flawed investment themes.

"That's why we've recently placed new trades on Suntech Power Holdings (NYSE: STP) and Cameco (NYSE: CCJ). There's no way high oil prices won't encourage more interest in these distressed sectors.

Suntech Power Holdings Co. (NYSE: STP), which saw its stock surge some 150% in 2007, didn't have such a good 2008 so far with its stock plunging about 44% year-to-date. But since setting a 52-week low of $28.19 on March 22, the stock has rebounded nicely, up over 55%. Roller coaster or what?!

Well, today, the maker of photovoltaic cells and modules said first-quarter earnings more than doubled on 76% higher revenue. Earnings reached $55.8 million, or 33 cents an American depositary share, beating analysts estimates of 28 cents. Revenue reached $434.5 million. Gross margins also expanded nicely and Suntech reiterated revenue estimates for 2008.

Early in the morning, STP shares jumped over 7% in premarket trading in response to the report but have not kept this up. Shares are now trading at $45.73, down over 1%, probably declining with the rest of the sector following Goldman Sachs's downgrade of Solarfun (NASDAQ: SOLF) to Sell from Neutral. SOLF shares are down over 18% taking LDK Solar (NYSE: LDK), Trina Solar (NYSE: TSL) and Canadian Solar (NASDAQ: CSIQ) down with it -- 5%, 8% and 13% respectively, to name but a few.

Suntech Power (NYSE: STP) closed at $47.12 Thursday.

STP is scheduled to report Q1 EPS on May 22.

STP June option implied volatility of 80 is above its 26-week average of 73 according to Track Data, suggesting larger price movement.

China Sunergy (NASDAQ: CSUN), a manufacturer of solar cell products in China, closed at $12.58 Thursday.

CSUN is expected to report Q1 EPS on May 20.

Cowen says: "Key issues: Ramp of new cells, expense control, liquidity."

CSUN June option implied volatility of 111 is above its 26-week average of 100 according to Track Data, suggesting larger price risk.

"Suntech Power Holdings (NYSE: STP), one of our long-time favorites, is now back on our buy list after being driven down in price by U.S. market volatility and the fallout from a recent earnings report," notes Jim Trippon.

The editor of The China Stock Digest explains, The company is world leader in the manufacture of photovoltaic solar cells and solar electric systems. And, it is developing a new technology to increase solar efficiency." Here is his review.

"The company's solar cells are used to supply power to the electricity grid within China, and it's the number one company in the Chinese solar energy industry. The company's systems also provide dependable power internationally for mobile phone networks and telecommunications relay stations and even street lamps in case of power outages.

"Certainly China is in desperate need of clean renewable sources of energy. Residents of major cities like Beijing and Shanghai are constantly enveloped in a choking cloud of smog. Beijing has said it wants a tenth of its energy to come from environmentally friendly sources by 2010.

"The problem with solar energy has always been the high cost of manufacturing solar cells relative to the amount of power output per cell. Suntech is attacking that problem with rigorous cost control and the competitive advantages that low cost Chinese manufacturers enjoy in the international arena.
