The latest Beige Book from the Fed showed that growth is definitely decelerating. The good news is that even the pygmies have figured that out by now. Stock traders and bond traders have been fighting over whether the slower growth means a double-dip recession or just anemic growth. There were only a few reports to watch, but many stocks and sectors were on the move.

Here are today's unofficial closing bell levels:

Dow Jones 10,387.54 +46.85 (0.45%)
S&P 500 1,098.90 +7.06 (0.65%)
Nasdaq 2,228.87 +19.98 (0.90%)

This morning, JA Solar Holdings (JASO) announced that it has signed multiple supply agreements with "several customers" to provide solar cells in 2011. The company will supply the solar cells from January 2011 through December 2011, but they are accompanied with prepayments or the delivery.

The company's CEO Dr. Peng Fang stated, "We are seeing very strong demand for our technologically advanced, high-quality products from our diverse global customer base ... Our customers view JA Solar as a reliable supplier partner and rely on JA to provide them with their 2011 product requirements."

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Abercrombie & Fitch Co. (ANF) received an analyst's upgrade ahead of next week's Q4 earnings report.
• Acer Inc. reported its highest quarterly earnings in almost three years due in part to growth in shipments.
• Baidu Inc. (BIDU) swung to a better-than-expected Q4 profit, with strong revenue growth, and offered rosy guidance.
• Biogen Idec Inc. (BIIB) offered an upside surprise as well as full-year earnings above Wall Street estimates.
• Coinstar Inc. (CSTR) strong quarterly results and guidance, as well as litigation concerns, failed to inspire Wall Street.
• Coca-Cola Co. (KO) posted strong Q4 and full-year earnings results due to growth in emerging markets.

On Thursday, solar firm JA Solar Holdings (JASO) upped its outlook for the year. The company shares rallied 9% Thursday as JASO topped the consensus estimate with its fourth-quarter earnings report by three cents. In addition, JASO raised its outlook for the fiscal year.

The company noted that it will produce solar panels with roughly 1.1GW of capacity during 2010 in an attempt to respond to growing global demand. For this reason, the company believes that an expected decline in average selling prices will be offset by increased sales. As a result of this news, Raymond James upped JASO to outperform from market perform with a target price of $6.50.

Today was a snow-recovery day where most were at work, but many businesses in the Atlantic Seaboard are still partially staffed. The weekly jobless claims managed to come down significantly, and it appears as though the appetite for risk is coming back as the Greece and other "PIIGS" issues may be closer to resolving, or are not as dire as many fear.

Here were today's unofficial closing bell levels:

Dow 10,144.19 +105.81 (1.05%)
S&P 500 1,078.47 +10.34 (0.97%)
Nasdaq 2,177.41 +29.54 (1.38%)

Last week, JA Solar Holdings Co. Ltd. (NASDAQ: JASO) posted a quarterly loss and lowered its guidance. But as interest in alternative energy continues to grow, analysts polled by Thomson Financial are still looking for good things from solar energy concerns scheduled to report earnings this week.

Strong growth at Trina Solar Ltd. (NYSE: TSL) in the third quarter prompted it to lift its guidance back in October. Analysts expect the Chinese company to post profits that are 76.3% higher than a year ago, or $1.18 per share on revenues of $268.4 million (+225.0%). Though Trina Solar missed estimates in the second quarter, analysts on average recommend buying TSL. Shares are down 81.4% from a year ago and trading near an all-time low.

Earnings of rival LDK Solar Co. Ltd. (NYSE: LDK) are expect to have risen 47.9% to $0.71 per share on revenues of $486.7 million (+206.6%). Also based in China, LDK has not missed estimates in recent quarters; in fact, it blew past expectations in the second quarter. Yet the consensus recommendation is to hold LDK. Like Trina Solar, LDK's shares are trading near an all-time low; the share price has fallen 50.0% in the past year.

Analysts anticipate third-quarter earnings for Canadian Solar Inc. (NASDAQ: CSIQ) to be a whopping 96.3% higher than a year ago, or $0.54 per share on revenues of $248.0 million (+154.5%). The company easily topped estimates in the previous quarter. ReneSola Ltd. (NYSE: SOL) and Suntech Power Holdings Co. Ltd. (NYSE: STP) are also expected to report earnings growth of 29.7% ($0.37 per share) and 23.8% ($0.42 per share), respectively. All three of these stocks reached 52-week lows last week, and all are considered buys.

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.

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?
