Today got a boost from a less-bad GDP that came in as a revised 1.6%. Slow growth, but not as slow as what was expected. Even an overdue warning from Intel did not manage to be bad enough to stall the market recovery. After Ben Bernanke said he'd do whatever it took to maintain a recovery, stocks and oil rose, and some of the air came out of the bond bubble.

Here were today's closing bell levels:

Dow Jones 10,151.18 +165.37 (1.66%)
S&P 500 1,064.60 +17.38 (1.66%)
Nasdaq 2,153.63 +34.94 (1.65%)

After the closing bell, SunPower Corporation (SPWRA) will take the spotlight to reveal its fourth-quarter earnings. Analysts surveyed by Thomson Reuters are expecting the solar concern to report net income of 49 cents per share, down from its year-ago profit of 70 cents per share. Sales for the period are expected to arrive at $491 million.

SunPower has a solid history in the earnings spotlight, having exceeded Wall Street's consensus expectations in three of the past four reporting periods. Judging by a recent uptick in call buying, some traders appear to be anticipating another upside surprise.

SunPower (SPWRA - option chain) shares are rising today after the company announced it will acquire SunRay Renewable Energy in a $277 million deal. SunRay is a European solar power plant developer. 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 SPRWA.

SPWRA opened this morning at $19.51. So far today the stock has hit a low of $19.30 and a high of $20.14. As of 12:40, SPWRA is trading at $20.01 up 90 cents (4.7%). The chart for SPWRA looks bearish and S&P gives SPWRA a negative 2 STARS (out of 5) sell ranking.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Altria Group Inc. (NYSE: MO) Q3 earnings beat by a penny but sales fell short of expectations; shares fell.
• AMR Corp. (NYSE: AMR) reported a Q3 net loss and plunging revenue but also raised $4 billion in cash.
• BB&T Corp. (NYSE: BBT) topped Q3 earnings expectations but said bad-loan provisions nearly doubled.
• Boeing Co. (NYSE: BA) missed estimates and posted a Q3 loss due to delays for a couple of jet products.
• Capital One Financial Corp. (NYSE: COF) shares rose after it reported better-than-expected Q3 numbers.
• Coca-Cola Co. (NYSE: KO) posted a better-than-expected Q3 profit but sales fell short, and shares fell.

This was the day that could have been. Earnings were coming out favorably, yet the data just couldn't support the stocks. There were also trader comments that BofA/Merrill had large sell orders or sell programs throughout the day. It looks like the DJIA even closed out under the 10,000 mark on an unofficial basis.

Here were today's unofficial closing bell levels:

Dow 9,974.75 -106.56 (-1.06%)
S&P 500 1,079.73 -13.18 (-1.21%)
Nasdaq 2,154.47 -10.82 (-0.50%)

Here are some highlights from last week's earnings coverage from BloggingStocks:

• AK Steel Holding Corp. (NYSE: AKS) posted a smaller-than-expected Q2 net loss as steel prices rise.
• Boston Scientific Corp. (NYSE: BSX) posted a better-than-expected Q2 profit on strong overseas sales.
• Caterpillar Inc. (NYSE: CAT) shares jumped after it beat earnings, missed revenues, and offered guidance.
• DuPont (NYSE: DD) shares declined after it posted a higher-than-expected profit but lower revenue.
• Eaton Corp. (NYSE: ETN) disappointing results were a sign that the bulls are in charge, said Jim Cramer.
• General Electric Co. (NYSE: GE) Q2 earnings and sales declined, dragged down by finance and NBC units.

Wells Fargo & Company (NYSE: WFC) and solar technology company SunPower Corporation (NASDAQ: SPWRA) teamed up today with an agreement for Wells to finance up to $100 million in new solar energy systems. SunPower will create agreements with end power users and handle operational issues, and Wells will finance and retain ownership of the systems, according to a pair of press releases from the two companies.

The Business Insider says that a research note from FBR Capital says this amount will allow SunPower to add about 20-25 MW of capacity, and that pricing for the solar power will be at competitive rates of under $0.15/kwh. The overall effect on earnings is expected to be immaterial. The average estimate for EPS for the 2009 fiscal year is $1.07, but with a wide range of $0.03 to $1.48. EPS last year was $2.28.

Crummy manufacturing and production data and continued weakness in housing data were not stopping buyers today. At least not until the last 90 minutes when we saw selling take away the triple digit gains in the DJIA. This looked like another day where bulls were washing out the bears until late-day from a DJIA financial component took much of the wind out of the sails today. But the tech-heavy NASDAQ was in negative territory most of the day. Here were today's closing bell levels:

Dow 7,216.97 -7.01 (-0.10%)
S&P 500 753.89 -2.66 (-0.35%)
Nasdaq 1,404.02 -27.48 (-1.92%)

Broadcom (NASDAQ: BRCM) reports tonight and it is getting hit due to the poor report from Qualcomm (NASDAQ: QCOM). QCOM lowered guidance quite a bit -- in fact, enough that I likely may not have to worry much about QCOM for the next couple quarters. Low $30's would present solid value.

Getting back to BRCM, I still feel it is one of the few must own chip names. I think it has enough innovation and diversification to avoid the 35-40% sequential reductions I am seeing from many in the chip space. However, I also think a lowering of the bar is priced into BRCM's shares and anything less than a disaster should keep the stock above $16.50 (assuming we avoid another shock down to the whole market). Anything around that level ($16.50) and lower would have me adding the shares. I've taken gains recently in trading shares and am hoping to add BRCM back on just a bit more weakness.

"If there ever was an opportunity to move energy efficiency strategies into the top-tier of national and industrial policy, it's now," says Toby Smith, referring to President-elect Obama's stated focus on renewable energy.

In his industry-leading ChangeWave Investing, which focuses on isolating emerging, long-term investment trends, he states, "The question isn't really if solar companies will benefit, but when." As a favorite idea for 2009, he looks to SunPower Corp. (NASDAQ: SPWRA).

"President-elect Obama seems to be the right person to push energy-efficiency initiatives through -- especially since he is preparing a massive stimulus program that will be unleashed soon after his inauguration on Jan. 20.

"The core of Obama's economic policy appears to be a strategy to transform the United States into an economy mostly powered by renewable and low-carbon energy generation by mid-century. This includes everything from solar to natural gas to nuclear.

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.
