After the closing bell on July 30, Massachusetts-based Evergreen Solar Inc. (NASDAQ: ESLR) reported second-quarter revenues of $63.8 million, compared to $55.8 million for the first quarter of 2009. The company's gross margin for the second quarter of 2009 was 1.9%, compared to 1.2% for the first quarter of 2009.

Unfortunately, these gross margins are way off the 34.7% we saw in the second quarter of 2008.

President-elect Barack Obama has often repeated his stance on alternative energy. He plans to spend $150 billion over 10 years on alternative energy, not only as part of his energy independence plan, but also in order to help clean the environment, and perhaps most important of all, to create 5 million new jobs.

With Obama winning in the polls, it is no wonder that on Tuesday solar stock prices soared: SunPower Corporation (NASDAQ: SPWRA) finished the day up 14.6%, Suntech Power (NYSE: STP) also closed 13.5% higher, Evergreen Solar (NASDAQ: ESLR) closed 12.8% higher, Canadian Solar (NASDAQ: CSIQ) was up 14.7% while Trina Solar (NYSE: TSL) gained 9.1%, First Solar (NASDAQ: FSLR) 9.6% and LDK Solar (NYSE: LDK) 4.8%. In fact, over the past week, these solar stocks added about 50% to their value: ESLR +104%, FSLR +55%, STP +53%, SPWRA +51%, LDK +48%, CSIQ +45% and TSL +41%. [Solar stocks are down this morning, seems to me a "sell on the news" decline.]

With these kind of gains recently you might think you're too late, but solar stocks have actually been beaten mercilessly in the past year. While the S&P 500 declined some 31% year-to-date and the Nasdaq declined 33%, solar stocks plunged even worse: STP -75%, TSL -73%, ESLR -69%, SPWRA -61%, CSIQ -56%, LDK -50% and FSLR -34%.

Congress passed a bill that approved about $18 billion of renewable-energy tax credits after repeated failed attempts to do so this year, and now there will be an administration that -- if it sticks to its claims -- will be more supportive of alternative energy. The only question investors should ask, so which do I pick?

Evergreen Solar, Inc. (NASDAQ: ESLR) plunged to an all-time low of $3.30 on Tuesday, thanks to the widespread ripple effect caused by Lehman Brothers' bankruptcy filing. As Evergreen confessed to a potentially substantial Lehman-related loss, analysts rushed yesterday to hand out price-target cuts. Today, Citigroup bucked the trend by upgrading ESLR from "sell" to "hold."

The bullish note seems primarily based on increased transparency regarding the Lehman situation, as well as a sharp decline in the stock's valuation. In a note to clients, Citigroup clarified, "With ESLR more clearly defining its exposure to a Lehman Bros. bankruptcy, the worst-case scenario is now well-defined . . . these issues appear much better discounted at current levels."

In response to the upgrade, ESLR has added more than 13% today. The shares are trading around the $5 mark, though, which puts them in territory not previously explored since May 2005. The stock's year-to-date loss now totals 75% -- a stomach-churning plunge, for sure, but the stubbornly bullish sentiment among investors suggests that more downside may be in store for Evergreen Solar.

Evergreen Solar (NYSE: ESLR) shares are trading higher today after the company announced today it has signed a sales contract with Germany's IBC Solar AG valued at $1.2 billion. Under the deal, the company will make the solar panels at a recently opened plant in Devens and at another factory expected to open in 2010. 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 ESLR.

After hitting a one-year high of $18.85 in December, the stock hit a one-year low of $7.52 in March. ESLR opened this morning at $10.16. So far today the stock has hit a low of $9.58 and a high of $10.22. As of 12:40, ESLR is trading at $10.11, up $0.95 (10.4%). The chart for ESLR looks bullish but deteriorating while S&P gives ESLR a very positive 5 STARS (out of 5) strong buy rating.

For a bullish hedged play on this stock, I would consider a September bull-put credit spread below the $7.50 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 19.0% return in just two months as long as ESLR is above $7.50 at September expiration. Evergreen would have to fall by more than 25.7% before we would start to lose money. Learn more about this type of trade here.

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.

Stocks were up today, but less than you might imagine after a large drop of more than $4.00 on oil in late-day prices. So much for Goldman Sachs' raising oil target again today, as well as lifting the oil services sector and upping price targets for some of the sector's stocks .

Interesting article on Apple's (NASDAQ: AAPL) iPhone "potential" teardown. Implications are that the 3G iPhone will carry higher margins than previous model. We will see shortly and I still expect Broadcom (NASDAQ: BRCM) to benefit from the actual teardown.

Speaking of Broadcom, the company got the all clear on a patent infringement deal with SiRF Technology Holdings (NASDAQ: SIRF) and I like the emerging technical setup on BRCM.

Elsewhere, Adobe (NASDAQ: ADBE) reports today and has been a solid tech name this year, really many years for that matter. I don't expect any big surprises.

Electronic Arts (NASDAQ: ERTS) is at the William Blair growth conference. Gaming sales were reported strong again last week. This is probably a cheap solid grower but I prefer the growing online gaming model, I've discussed on the Buzz in the past.

SunPower (NASDAQ: SPWR) was upgraded this morning and presenting at an Alternative Energy conference on Wednesday. I was going to trade this again but the analyst action is spiking the stock today.

Evergreen Solar's (NASDAQ: ESLR) shareholder and analyst meetings is scheduled this week and I'm thinking this could fuel bullish action.

Regarding Comverge (NASDAQ: COMV) and EnerNOC (NASDAQ: ENOC), I overheard some bullish comments on these stocks on CNBC this morning. I've discussed COMV on the buzz previously and ENOC is their sister company. Both companies offer technology solutions for managing the power grid more efficiently and I think both stocks are cheap emerging growth stocks.

Position in BRCM, ESLR, COMV.
