Today was one of those up days that started out strong and ended stronger. The gains were on the heels of overseas buying and on the dollar weakness. The dollar weakness trumped Hurricane Ida's downgrade to a tropical storm when it came to higher oil prices.

Here were today's unofficial closing bell levels:

Dow 10,227.40 +203.98 (2.04%)
S&P 500 1,093.10 +23.80 (2.23%)
Nasdaq 2,154.06 +41.62 (1.97%)

Today was one of those days that felt as though it was another mini-disaster. Another 600,000 weekly jobless claims were coming to roost. A late day note that the Obama administration was ready to subsidize troubled houses with partial buy-downs of loans to avoid repossession helped to bring on a recovery. While this is far from set in stone and far from being "a done deal" it created a monster to save to otherwise nasty trading day. If you were here all but the last hour it would have been just another miserable day. Here are today's unofficial closing bell levels:

JA Solar Holdings Co. Ltd. (NASDAQ: JASO) took a beating after lowering targets to 2009 revenue of $830 to $952 million, under analyst estimates of $993.8 million. The company already cut its revenue projections by more than 20% in November. Here is what we see as the problems in solar energy right now. Shares were off by 16% at $2.51 right before the close.

China-based Suntech Power Holdings (NYSE: STP) is slated to report its third-quarter earnings results ahead of the opening bell tomorrow, and the solar stock looks particularly vulnerable to a post-report drubbing. Sector peer JA Solar (NASDAQ: JASO) fell to an all-time low last week after offering a weak outlook, while Trina Solar (NYSE: TSL) today lowered its revenue forecast for 2008.

Currently, First Call reports that analysts are expecting STP to report a quarterly profit of 42 cents per American depositary receipt. Suntech has a respectable history in the earnings spotlight, having exceeded the Street's forecast in three out of its past four reports.

On the plus side, it seems as though many brokerage firms have already downwardly revised their expectations for STP. There have been 10 cuts to the firm's average 2008 earnings-per-share estimates, compared to just two increases.

Plus, several analysts have issued bearish notes on Suntech in the past few weeks: Jefferies & Co. cut its price target on November 17; JPMorgan Chase cut the stock from "neutral" to "underweight" and lowered its price target on November 16; Raymond James downgraded STP from "strong buy" to "outperform" on November 13, the same day that AmTech Research slashed its price target; and Deutsche Bank cut the stock from "hold" to "sell" on November 10.

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.

Dell (NASDAQ: DELL) is up 9% on strong earnings.

Marvell Technology (NASDAQ: MRVL) is up 17% on good numbers.

Sigman Designs (NASDAQ: SIGM) is off 18% on weak earnings.

JA Solar (NASDAQ: JASO) is up almost 7% on no visible news.

Stocks may trade differently in the pre-market than they do in the regular session.

Solar energy may be the wave of energy's future, but companies such as Google (NASDAQ: GOOG) and Chevron (NYSE: CVX) may best start-ups in getting to the benefits. A number of large American companies with tremendous balance sheets are pouring money into solar energy based on the fact that it is becoming more competitive with oil.

According to Bloomberg, "Costs for the technology will fall below coal as soon as 2020, the U.S. government estimates. JPMorgan Chase & Co. and Wells Fargo & Co. invested last year in the biggest solar plant built in a generation; Chevron and Google are funding research; and Goldman Sachs is seeking land to lease as demand out-paces wind turbines and geothermal."

Given the potential size of the bonanza, the investments should not be surprising, but they could squeeze smaller solar energy companies out of the market. Firms like JA Solar (NASDAQ: JASO) and SunTech (NYSE: STP) have their entire futures bet on the success of solar energy and the fact that there are not many companies in the business, at least until now.

It has began to occur to large companies that if fossil fuels will indeed start to run low in two or three decades that the trillions of dollars in market cap currently represented in large oil company stocks will have to go somewhere.

Why not to Google?

LDK Solar Co. (NYSE: LDK) is one strange solar stock. Yesterday, on a day when other solar companies like Solarfun Power Holdings (NASDAQ: SOLF), Canadian Solar Inc (NASDAQ: CSIQ), First Solar Inc (NASDAQ: FSLR) and JA Solar Holdings (NASDAQ: JASO) were all strong and despite earnings coming in at the high end of expectations and guidance solidly ahead of estimates, their stock was down. Not only was it down, but it also tried rebounding, only to fail. Not good at all for the bull case.

Experience has taught me to respect the price action the day after earnings. So when I see LDK trying to break out of a now 5-month old range, pretty much between $30 and $40 -- yes it was up to $50 in January and $20 in March, but those are outliers -- this is a very bearish sign. It's so bearish that I suspect that unless solar plays really heat up again, this stock will need many more weeks or months to break $40, and even then, it's got a ton of resistance all over the place due to bitter buyers in at much higher prices who will be looking to cut their losses.

Everyone is talking about solar. Whether you believe that solar energy will somehow displace an oil-driven economy or not (I don't), some of these stocks like First Solar (NASDAQ: FSLR) and JA Solar (NASDAQ: JASO) have seen big gains over the past few years.

The success of solar companies has not been lost on ETF firms with their constant new products hitting the market. A smaller ETF firm called Claymore Securities looks to be first to the market with a solar ETF, the Claymore/MAC Global Solar Energy Index ETF, with an aptly-named ticker, (NYSE: TAN).

Here's Claymore's website for the recently launched ETF. From the firm's website, the index defines a company engaged in solar energy as falling into two main categories:

1. Solar photovoltaic power, which involves the conversion of sunlight into electricity through the photovoltaic process; and

2. Thermal solar power, which involves using energy from the sun to heat fluids for purposes of water or space heating or to produce electricity.

MBIA (NYSE:MBI) is off almost 5% on a large quarterly loss.

Fedex (NYSE:FDX) is off 3% after revising its forecast down due to higher fuel prices.

JA Solar (NASDAQ:JASO) is up almost 2% after beating earnings expectations.

LDK Solar (NYSE:LDK) is up 1.5% on expectations of strong earnings.

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?

Last month at the Sundance Film Festival, I saw some great movies, partied it up a bit and schmoozed with celebrities. Perhaps it's the pseudo-celebrity status that came with my TV show or the $300,000+ personal loss I took on an investment I truly believed in, but I never get starstruck anymore. Not with celebrities and definitely not with companies. And as an investor, you can learn from this. I'll explain.

While at the festival, I bumped into "celebrity" Maria Bello, and my ability to have a casual conversation with her led to an interesting encounter highlighted by some flirting and several great pictures (see them all HERE).

Ms. Bello barely gave starstruck, incredibly crazed, fans the time of day; after all, nobody -- celebrity or not -- can really take anybody who's screaming and crying in awe of their presence very seriously. So, while it was a fun moment for me, I couldn't help but think how this related to the stock market.
