Late Thursday, Standard & Poor's announced a few changes to its U.S. indices. The reason for the changes are that Wyeth (NYSE: WYE) is being acquired by Pfizer (NYSE: PFE), leaving an opening in both the S&P 100 and S&P 500 (SPX). I want to focus on the stock that will replace WYE in the SPX, First Solar (NASDAQ: FSLR). In after-hours trading, FSLR jumped more than 6% in response to the announcement.

FSLR manufactures solar modules and is a major benefactor of what I like to call the "green rush" that took place during the past two years. FSLR capitalized nicely on the global environmental consciousness revolution last year, ascending as high as the $310 region. Yes, the stock has backed off quite a bit due to the economic crisis, but it could enjoy a bit of a recovery provided it can parlay this latest news into a breach of some overhead resistance.

Another record deficit, a Geithner likely tax boost, and higher import prices failed to significantly spook the markets even after a five or day run-up. Based on the late day recovery, where this close was going to end up was an unknown until right at the closing bell. The day was a very light day for news, so here are the closing bell levels (unofficial close):

Dow 9,603.98 -23.50 (-0.24%)
S&P 500 1,042.73 -1.41 (-0.14%)
Nasdaq 2,080.90 -3.12 (-0.15%)

Today was supposed to be all about GDP. We got a mere 1% preliminary reported drop in Q2 GDP, much narrower than the -1.5% expected. Yet the market sold off on the news. The the indexes spent much of the day deciding whether to stay up or to go down.

Here were today's unofficial closing bell levels:

Dow 9,171.39 +16.93 (0.18%)
S&P 500 987.44 +0.69 (0.07%)
Nasdaq 1,978.50 -5.80 (-0.29%)

A trade doesn't simply have an initiation and finale – the most important part of a trade is its evolution and constant re-assessment if the original thesis that the trade was initiated with, still holds true.

On that note, let's look at First Solar (NASDAQ:FSLR). I started a short position in it on 6/1 when instead of participating in the market advance, it lagged (due to a LA Times story that FSLR's acquisition of "strategic land rights" is under scrutiny). Recall, it came on the heels of a cautious mention in Barron's on May 26th. So, both times, FSLR reacted negatively to negative news and volume picked up on both those instances.

Today, Pacific Crest Securities reiterated its buy rating on FSLR and called the recent weakness a "buying opportunity."

I

Generally, my bias is toward large-cap companies with a demonstrated business model. In a nutshell, "experimental" business models need not apply. However, every once in a while I make an exception, and First Solar (NASDAQ: FSLR) is one. Here's why:

In addition to growth potential for its proprietary thin film semiconductor solar module technology, First Solar has a building macroeconomic tailwind in the bottoming U.S./global recession and dawning recovery. The First Call FY2009/FY2010 EPS estimates for FSLR are $7.18 to $8.72.

The shares of First Solar, Inc. (NASDAQ: FSLR) have started the week on a rocky note. Not only did Friedman, Billings, Ramsey & Co. downgrade the stock from Market Perform to Underperform, the alternative energy issue was also the topic of a skeptical Barron's article over the weekend.

In a note to clients, brokerage firm Friedman cited weak polysilicon prices and the stock's overrich valuation for its downgrade. FSLR closed last Friday at $191.72 per share, compared to Friedman's price target of $110.

Meanwhile, the cautious Barron's write up [subscription required] observes that the Intersolar trade show begins Wednesday in Munich, and pits FSLR against many lower-priced rivals. "One leading customer says it will ditch First Solar's 'thin-film' panels if crystalline silicon alternatives keep getting cheaper.

That seems likely. Silicon prices are expected to drop another 30% by year end. First Solar profits -- and its shares -- could get cut in half," commented the financial paper.

A late-day rally based on more Bernanke and Geithner data on stress tests and bank packages took away the sting of what was considered a defeat for banks and big business after Obama's speech last night. Existing housing data added to pressure this morning, but again this was trumped at the end of the day. Here were today's unofficial closing bell levels:

Dow 7,270.65 -80.29 (-1.09%)
S&P 500 764.87 -8.27 (-1.07%)
Nasdaq 1,425.43 -16.40 (-1.14%)

Yesterday, solar firm First Solar (NASDAQ: FSLR) announced that its fourth-quarter profit more-than doubled in the face of declining demand for its products. Arizona-based FSLR raked in $1.61 per share in the fourth quarter, up from 77 cents per share a year earlier. The Street expected earnings of $1.30 per share.

Fourth-quarter sales increased to $433.7 million, far better than the expected $410.4 million. Full-year sales totaled $348.3 million, with earnings checking in at $4.24 per share.

"President Obama has stated that he's been studying Roosevelt's first 100 days and the way out of the current economic mess will look a lot like the New Deal," says David Fessler.

The advisory panelist for The Oxford Club explains, "Seventy-five years after Roosevelt's inauguration, I think we will soon see President Obama get the ball rolling on his version of the New Deal, focused on two very specific areas: energy and infrastructure." Here, he looks at stocks poised to benefit.

"Saving energy will be one of his first initiatives. It's what will give us the quickest bang for our buck. Better insulation in homes, programmable thermostats, fluorescent bulbs, more fuel-efficient cars, energy management systems for use in larger-scale commercial buildings and beefed-up public transportation are just a few of the ways to save energy.

"The government will likely offer attractive tax incentives to rally support. So who stands to prosper from such initiatives?

"Big blue-chip companies, like Owens Corning (NYSE: OC), maker of insulated glass and building insulation; General Electric (NYSE: GE), manufacturer of wind turbines, energy control and infrastructure products; and Johnson Controls Inc. (NYSE: JCI), maker of energy management systems (for buildings and vehicles) and hybrid vehicle batteries.

Shares of First Solar (NASDAQ: FSLR) have been pummeled this week, as analysts, starting with Citigroup (NYSE: C), downgrade the stock.

Previously, the stock had enjoyed high ratings, generally in the Buy or Accumulate range. With Citi leading the way, other analysts have followed suit with rating reductions.

Citi cited concerns regarding the amount of solar panel inventory waiting to be absorbed, along with worries about future demand.

By some estimates, only 10% of the solar panels in inventory at the end of the year will be taken up by the anticipated increased demand generated from the adoption of the Obama energy proposals. An additional 20% reduction of inventories is projected to result in 2010.

The market is not distinguishing among the companies in the solar panel manufacturing business. Regardless of the strength of an individual manufacturer, all are being treated with the same lack of enthusiasm by analysts and investors. A closer look at First Solar suggests that this should not be the case.

First Solar is a leading designer and manufacturer of solar modules using thin-film semiconductor technology, which converts sunlight to electricity. Based in Phoenix, Ariz., First Solar has long-term supply contracts with 12 European project developers and systems integrators.

The solar module industry has come into recent criticism for its impact on the environment. Concerns are being raised that the eventual disposal of solar panels will result in the emission of large amounts of greenhouse gasses as the semiconductors disintegrate.

First Solar, however, has established a model for extended producer responsibility, which creates an obligation of the producer to have policies and practice to ensure that the company takes responsibility for environmental consequences from cradle to grave. The company provides the purchaser of its products with a guarantee to take back all its panels at the end of their useful life.

First Solar has received acclaim for building concern for environmental impact into all phases of the manufacturing and recycling of its products.

FSLR stock is trading around $142 per share. Shares had rallied last week to $165 per share on the heels of President-elect Obama's energy proposals. The stock had increased in price by 76% from its 52-week low, and was approaching its 12-month target price of $167.70.

The sell-off of FSLR has been greatly overdone. The company's balance sheet is strong, with a long-term debt-to-equity ratio of 0.10 and a current ratio of 3.23. The 21.84% on equity should also be of comfort to investors.

An additional plus for FSLR is the likelihood of a push to solar energy as part of the job stimulus program of the new administration.

Louis Navellier's PortfolioGrader Pro, which rates Wall Street stocks, rates FSLR a B or Buy.

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.

This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"It looks very much to me like there will be a rough few years ahead in the United States, whichever candidate wins; however, if Obama wins, we see opportunity in select stocks such as Microsoft, Time Warner and First Solar," says Martin Hutchinson in The Money Map Reporter.

"If Obama takes the White House, interest rates will surely rise. And the major beneficiaries of a policy of higher interest rates will be companies with large piles of cash, who will earn better returns on that money even as they discover cheaper opportunities to deploy it as prices of highly leveraged competitors crash.

"Microsoft Corp. (NASDAQ: MSFT), for example, with $23 billion of cash and negligible debt, should find many ways to deploy that capital and convert it into profitable business opportunities.

"Another sector that might benefit is media, which always finds it easier to sell products internationally when the United States has a popular "rock-star" president than it does when an unpopular president occupies the White House.

"You might look at Time Warner Inc. (NYSE: TWX), which is largely concentrated in visual and Internet media, without investments in the rapidly declining newspaper sector.

"Finally, you might look for a new energy company that could benefit from Obama's proposed $150 billion alternative energy fund.

"One possibility would be First Solar (NASDAQ: FSLR), though -- at 39 times earnings and with a market capitalization of greater than $20 billion -- the stock certainly isn't cheap, despite the company's global reach."

Analyst Michael Molnar of Goldman Sachs took a harsh tone on the solar sector today, slashing his opinion to Sell on both First Solar, Inc. (NASDAQ: FSLR) and SunPower Corp. (NASDAQ: SPWRA). Specifically, First Solar was slashed to Conviction Sell from Buy, while SunPower was dropped from Buy to Sell. In a note to clients, Molnar explained, "We strongly believe that SunPower and First Solar are two of the best solar companies in the world and that both will be part of the growing solar industry for years to come. However, in our view, even these companies will face headwinds in a market that is oversupplied with modules."

Specifically, "the risk of oversupply in the solar market will soon become a reality as considerably less generous demand subsidies take hold just as a wave of supply and tight financing hit the market," said Molnar. He added, "We believe that liberal subsidies of the past in markets like Germany and Spain are unlikely to be replicated in the future, given fears of their ultimate cost in a bad world economy."

As a whole, Goldman maintains a "cautious" view of the solar sector -- and the brokerage firm isn't alone. Piper Jaffray also weighed in on solar firms today, with a warning that higher credit costs could reduce average selling prices by an additional 6%. "The renewables industry depends on access to credit, and for the moment, the credit market remains closed," Piper stated. "We believe the cost of capital on renewable projects will increase due to higher bank financed interest rates, larger spreads, and more upfront fees." For 2009, Piper Jaffray predicts that companies' average selling prices will fall by 15% to 21%.
