With the high fuel prices over the past year, solar stocks have been making some nice gains. But there are some signs that they may not be as safe as they appear. Investors' interest in solar companies increased due to soaring crude futures, but there are some factors to take into account before investing money into solar.

The current BusinessWeek looks at stocks such as First Solar (NASDAQ: FSLR), SolarWorld and Evergreen Solar (NASDAQ: ESLR), which have been facing increased volatility based on contract deal news or the lack thereof.

A major impact came in May, with speculation that Germany would lower subsidies given to companies and individuals who install alternative energy equipment. But the cut was not as deep as expected and stocks rebounded nicely.

First Solar (NASDAQ-FSLR) is recently up $2.06 to $247.02 in pre-open trading.

Calyon has a Buy rating and $345 price target on FSLR. Calyon says: "The company is not exposed to the German utility scale market (the destiny of which has now been determined for at least the next 2 to 3 years)."

FSLR July option implied volatility of 70 is near its 26-week average according to Track Data, suggesting non-directional price risks.

First Solar (NYSE: FSLR) closed at $273.18 Wednesday.

Calyon says: "The German solar feed-in tariff (FIT) is under fire, as lawmakers are considering an accelerated digression that would reduce rates 25% by 2010 versus 15% under current law."

FSLR July option implied volatility of 58 is below its 26-week average of 73 according to Track Data, suggesting decreasing price risks.

MOST NOTEWORTHY: First Solar, Pride International and EnerSys were today's noteworthy downgrades:

• Friedman Billings downgraded First Solar (NASDAQ: FSLR) to Underperform from Market Perform citing margin risk concerns, as the company aggressively pursues utility-scale projects in the US. The firm said risks are not reflected in share valuation near $300 and could be a source of disappointment but could also lead to downside EPS risk.
  
• Wachovia said Pride International (NYSE: PDE) has the least potential EPS upside vs. peers given the company has contracted the highest percentage of its floater days into 2012E. Additionally, the firm views a takeout by Seadrill as unlikely. Shares were cut to Underperform from Market Perform.
  
• Merriman downgraded shares of EnerSys (NYSE: ENS) to Neutral from Buy as they believe the strong Q4 results were driven by a one-time benefit from lead procurement mechanics and that data does not support the company's sustained margin expansion story.

OTHER DOWNGRADES:

• Citigroup lowered Intuit (NASDAQ: INTU) to Hold from Buy.
  
• UBS downgraded Nucor (NYSE: NUE) to Neutral from Buy.
  
• Smart Modular (NASDAQ: SMOD) was downgraded at Oppenheimer to Perform from Outperform.
  
• The Airlines Sector was cut by Soleil to Neutral from Outperform.

Peter Way selects his buys by following the trading activity of block traders -- those making large, million dollar bets. Here's the latest from his Block Trader Oil & Gold Monitor.

"The volume stock market liquidity-providers are hedging their necessary position risks in ways that foretell declining oil stock prices. Their records on such outlooks in the past are pretty good, so pay attention.

"The million-dollar market-makers are not always right, and here they tend to be a bit early, but it's obvious they can save you some grief and provide a chance to pick up some meaningful extra profit.

"From our recent review of energy ETFs, we also note that the pros' perception seems to be that energy stocks have been bid up too far. Ok, so what to do? Sell the oil holdings? Then where to put the proceeds?

First Solar (NASDAQ:FSLR) is recently up $24.10 to $275.70. FSLR is a manufacturer of solar modules with an advanced thin semiconductor process. FSLR call option volume of 27,209 contracts compares to put volume of 32,567 contracts. FSLR April option implied volatility is at 75, May is at 89; above its 26-week average of 74 according to Track Data, suggesting larger price risks.

MOST NOTEWORTHY: Analog Semiconductors, OrthoVita and First Solar were today's noteworthy initiations:

• Morgan Stanley initiated Analog Semiconductors with an In Line rating. The firm assumed National Semiconductor Corp (NYSE: NSM) with an Overweight rating and $26 target and is the firm's top pick; Analog Devices (NYSE: ADI) and Linear Tech (NASDAQ: LLTC) were initiated with Equal Weight ratings and a $32 target and $34 target, respectively.
  
• Barrington believes OrthoVita (NASDAQ: VITA) is the market share and technological leader of the biomaterials market. The firm assumed shares with an Outperform rating and $4 target.
  
• Canaccord Adams believes First Solar's (NASDAQ: FSLR) management and business model are among the best of any PV company and that execution has led to strong profitability plus a successful aggressive capacity ramp. Shares were started with a Buy rating and $325 target.

OTHER INITIATIONS:

• Morgan Stanley initiated Yum! Brands (NYSE: YUM) and Domino's Pizza (NYSE: DPZ) with Equal Weight ratings and targets of $40 and $15, and also initiated McDonald's (NYSE: MCD) and Burger King (NYSE: BKC) with Overweight ratings and targets of $65 and $34.
  
• Lehman initiated Alcoa (NYSE: AA) with an Overweight rating and $44 target.

Investors frequently like to chase "hot stocks." While not based on fundamentals, momentum investing does sometimes work as stocks that are "working today" frequently "work tomorrow" as well.

So, as 2008 is 1/6th done, it's time to look back at the highfliers from 2007 and see where they're trading today. As usual, the analysts at Bespoke Investment Group have some good data and charts for us.

In a post, titled "How the Best Have Done," Bespoke analyzes the best performing U.S. stocks of 2007 and tracks them into 2008. The results:

• First Solar Inc. (NASDAQ: FSLR), 2007's best performer, is down 21.86% year to date. See BloggingStock's Aaron Katsman's article on why he shorted this stock into the New Year.
  
• The second best, Onyx Pharma Inc. (NASDAQ: ONXX), is down 49.51%.

While some solar stocks are down big in 2008 after a huge run-up in 2007, the big winners are heavily concentrated in materials, agriculture, and energy. BPZ Resources Inc. (AMEX: BZP) is the stock on the list that has done the best in 2008 -- rising another 44% so far this year.

Thursday marked the end of the first month of the new year ... and what a market. Investors have been through the proverbial ringer from January 2 right through January 31. The market ended up 200 points Thursday to wrap up the craziest January I have seen in my 30 years! So what happened and where do we go from here?

Superb growth stocks of 2006/ 2007 have seen the foam come off the top of their superb performance. Names like Intuitive Surgical (NASDAQ: ISRG), Apple (NASDAQ: AAPL), Google (NASDAQ: GOOG), First Solar (NASDAQ: FSLR) and others have seen valuation reductions of up to 30-35%. Bad businesses? No. Changing business models? No. Tough environment? Yes. Think of the example of a Major League baseball team winning its division one year by garnering 96 victories, but the next year winning 93 games to capture the same division title. Bad team? No, just a different environment, and still winning its division.

The economy has taken a step back and said to these companies, "if you thought you could have 30% growth ... think again, it's going to be 25% instead this year." The growth bar gets re-set and so do the valuations. The important point is that many terrific companies weather through these periods and when economic times improve, they go back and capture even higher valuations than before the slow down.

With stock markets continuing to free fall, investors should explore the option of tax-loss selling now. While harvesting losses on stocks to offset capital gains is customarily done in October and November, smart investors will realize that there is no reason not to do the same now. Over the last week, I have been working with my clients to sell their losers and realize the loss. Either they will be able to use the losses to offset gains which hopefully will come later on this year, or the losses can be rolled over for next year as well.

Those of you in former high fliers such as Baidu.com (NASDAQ: BIDU), First Solar (NASDAQ: FSLR) and Apple (NASDAQ: AAPL) who are lamenting your steep losses of the last month have no fear. By taking losses on those stocks now, you may actually profit from your losers.

Experience has taught me that catching falling knives in the stock market is incredibly dangerous, but some of these speculative names are really beginning to test my resolve. So I thought I'd share them with you.

Investors have been punishing these plays not because business has fallen off a cliff, but because they are some of the most speculative stocks around -- other than penny stocks -- and in this kind of market environment, investors prefer safety. That creates opportunity, if you're willing to take on some risk. After all, these companies still have solid business fundamentals, so there will be a bottom somewhere, and I think we're getting very close to it here. For now, put these on your watchlist, for when they do bounce, they're going to bounce hard, think 15-20% within days.

Garmin (NASDAQ: GRMN) -- At $64, this navigation system maker is down 35% on the year, but revenue growth is far greater than its current P/E of 15. Sure, there's some margin concerns, but the chart has solid support at $60.

With the continued weakness in financial markets, I am reminded of a saying by old Jewish sages about 1800 years ago. In the book Ethics of the Fathers the question is asked, "who is happy?" The answer given is,"he who is happy with his portion."

With that in mind, I am suggesting to readers to close their short position on First Solar (NASDAQ: FSLR) and book a gain of more than 32%. As a reminder, First Solar was my top short of '08, and while I would have expected to keep the short on for more than just a couple of weeks, sometimes you just need to book a profit. Not bad for 16 days. Though I still believe that all these alternative energy stocks are trading too high, 32% in 2.5 weeks is a nice return and I suggest booking it.

Remember: Some times the bulls win and sometimes the bears win, but the pigs never win.

Happy trading!

With First Solar (NASDAQ: FSLR) stock getting hammered, I have been asked by some traders if I would recommend that they close their short position in First Solar. To remind you, First Solar was my top short recommendation of 2008, and since the first trading day of '08, the stock is down about 25%. While there may be a short-term bump up in the stock in the next few days (how many days in a row can the NASDAQ drop?), the reasons behind the short trade are still in place, and I wouldn't be in a hurry to close the position. The stock is still trading at a high valuation, and I still think that the "alternative energy" bubble is in the midst of bursting. With earnings estimates forecasting 65-70% growth in EPS for '08, the stock is far too expensive. With a P/E nearing 160, this has bubble written all over it.

The stock has gotten crushed with crude oil prices still near record levels. If crude prices drop 10-20%, all of these alternative energy stocks will continue to fall rapidly.

"I can't believe I won," cried Jordin Sparks, winner of last year's American Idol. Within seconds, industry and non-industry drones alike began formulating ways to attach themselves to her in some way, crazy in anticipation of the inevitable riches.

Months later, several Wall Street types were overheard saying, "I can't believe oil keeps going higher, alternative energy stocks are going to be hot, hot, hot," and thousands of investors went wild buying shares of the dozen or so solar stocks, crazy in anticipation of the inevitable riches.

Each industry has its stars: Kelly Clarkson, Carrie Underwood and Clay Aiken -- as determined by album sales -- for American Idol, First Solar (NASDAQ: FSLR), Sunpower (NASDAQ: SPWR) and MEMC Electronic Materials (NYSE: WFR) -- as determined by stock performance -- for the solar industry.
