Trina Solar Limited (TSL) is having a little trouble this session getting a bid. Actually, it's having a lot of trouble. At the time of this writing, the company's American Depository Shares (ADSs) were down 7% to $22.21. Significant volume accompanied the sell-off.

Earlier today, the maker of solar photovoltaic items reported results for the third quarter. According to Reuters, sales went up over 100% to $508 million. Net income of $1.08 per ADS beat the consensus estimate by 21 pennies. The gross margin experienced an improvement on a year-over-year basis. Seems like a data set that should be bought, right?

Both Walmart (WMT) and BJ's Wholesale Club (BJ) reported strong quarterly results last week, suggesting that discount retailers are still doing well even as the economy seems to be coming around. This week, Costco (COST) and Big Lots (BIG) take their turns in the earnings spotlight, and analysts surveyed by Thomson Reuters expect a strong showing from them as well.

And we'll round out this preview of the coming week with a look at expectations for AutoZone (AZO), Canada's big banks, and Trina Solar (TSL).

By now, nearly every person in this country has heard or read about a second oil rig accident which has happened near Morgan City, Louisiana. Although it appears that only a small amount of environmental damage was done, how will the reaction to this news play out in the markets through the coming week?

I'm very thankful that this most recent oil rig accident happened late on a Friday. I certainly believe that if this accident had happened a few hours earlier in the day, I probably wouldn't have liked to witness the way the markets reacted. Now, we have two days to absorb the news of what has happened before full-scale trading resumes. Really, I'm very happy about that.

How many days in a row can stocks rise? Now we are seeing the panic buying or a melt-up, as some in the media are calling it. A stronger Philly Fed index helped, as did CPI and weekly jobless claims. Today was either 8 or 9 days up for the DJIA. Rumors of Greece needing to go the IMF and even a rumor that the Fed might lift the discount rate again did not even kill the market.

Here were today's unofficial closing bell levels:

Dow 10,779.17 +45.50 (0.42%)
S&P 500 1,165.82 -0.39 (-0.03%)
Nasdaq 2,391.28 +2.19 (0.09%)

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

• Aeropostale Inc. (NYSE: ARO) strong Q2 results beat expectations due to rising same-store sales.
• Agilent Technologies Inc. (NYSE: A) Q3 earnings topped low expectations and revenue declined.
• Analog Devices Inc. (NYSE: ADI) posted better-than-expected Q3 results but shares fell on weaker margins.
• Baidu Inc. (NASDAQ: BIDU) CEO said its new advertising efforts will boost sales over the long run.
• Barnes & Noble Inc. (NYSE: BKS) had a better-than-expected Q2 profit but same-store sales fell.
• BJ's Wholesale Club Inc. (NYSE: BJ) reported solid Q2 numbers and raised its full-year guidance.

Trina Solar (NYSE: TSL), a maker of solar photovoltaic products and a colleague of Suntech Power Holdings (NYSE: STP), issued second-quarter results on Monday after the market closed. According to Reuters, Trina Solar beat market expectations.

Revenues decreased over 26% year-over-year (according to the actual press release, revenues increased over 13% on a sequential basis). Net income was 71 cents per American depositary share (ADS). Analysts were betting on 37 cents per ADS being the likely profit figure.

Analyst upgrades:

• JP Morgan upgraded J.C. Penney (NYSE: JCP) to Neutral from Underweight based on lower input costs, stabilization in home, lower markdown dollars, and valuation.

• ConocoPhillips (NYSE: COP) was raised to Buy from Neutral at Goldman.
• China Housing (NASDAQ: CHLN) was upgraded to Buy from Hold at Roth Capital.

Trina Solar (NYSE: TSL) is set to step into the earnings spotlight today, with Wall Street expecting a fourth-quarter loss of 4 cents per share. This past year hasn't been kind to TSL as far as earnings are concerned. In two of the three earnings reports thus far, TSL has missed the consensus estimate -- both times by a rather wide margin.

There is no doubt that solar firms have lost a bit of their sizzle, what with dropping crude prices and tightening pursestrings. Unfortunately for TSL, it has been caught up in the wave of downside pressure. Even if the firm bucks the recent trend and reports better-than-expected earnings, it may not rally much, thanks to a massive amount of overhead pressure. TSL's 10- and 20-week moving averages are in position to stop any rally attempt, a role that they have filled since the middle of 2008.

While the release of economic data doesn't stop next week (see economic schedule highlights below), the earnings season does wind down dramatically. Most of the S&P 500 companies already have reported on the past quarter, which means dismal earnings news is largely behind us, at least for a while. About the only companies of note expected by analysts surveyed by Thomson Reuters to report falling earnings this week are Costco Wholesale Corp. (NASDAQ: COST), Wendy's/Arby's Group Inc. (NYSE: WEN), Foot Locker Inc. (NYSE: FL), Bank of Montreal (NYSE: BMO), and Steinway Musical Instruments Inc. (NYSE: LVB).

While PetSmart Inc. (NASDAQ: PETM) and Big Lots Inc. (NYSE: BIG) quarterly profits are expected to be about the same as a year ago, Liz Claiborne Inc. (NYSE: LIZ), Kenneth Cole Productions Inc. (NYSE: KCP), Ciena Corp. (NASDAQ: CIEN), and Trina Solar Ltd. (NYSE: TSL) are expected to have swung to losses in the most recent quarter.

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

• AnnTaylor Stores Corp. (NYSE: ANN) posted dismal Q3 results as same-store sales sank.
• Autodesk Inc. (NASDAQ: ADSK) declined to release an outlook for next year due to the economic turmoil.
• BASF AG (OTC: BASFY) profit warning resulted in analysts' upgrades and downgrades both.
• Dell Inc. (NASDAQ: DELL) handily beat Q3 expectations due in part to share buybacks.
• GameStop Corp. (NYSE: GME) missed Q3 earnings expectations and same-store sales declined.
• Hewlett-Packard Co. (NYSE: HPQ) forecast Q4 results above estimates on cost cutting and global reach.
• Home Depot Inc. (NYSE: HD) reported better-than-expected Q3 results though sales had declined.
• LDK Solar Co. Ltd. (NYSE: LDK) Q3 earnings more than doubled and revenued surged 70%.
• Lowe's Cos. Inc. (NYSE: LOW) posted better-than-expected Q3 results though same-store sales slipped.
• McDonald's Corp. (NYSE: MCD) 2009 earnings prospects resulted in an analyst's upgrade.
• Nokia Corp. (NYSE: NOK) earnings warning resulted in upgrades from a few analysts.
• PetSmart Inc. (NASDAQ: PETM) topped expectations and forecast full-year profits higher than estimates.
• Suntech Power Holdings Co. (NYSE: STP) fell short of earnings expectations and lowered its guidance.
• Trina Solar Ltd. (NYSE: TSL) Q3 earnings quadrupled and revenue more than tripled on increased demand.

Increasing demand for solar energy and solar products proved to be a boon for Trina Solar Ltd. (NYSE: TSL) and LDK Solar Co. Ltd. (NYSE: LDK) as both companies reported Wednesday that their earnings soared in the third quarter. Investors were not impressed, however, pushing shares lower.

Trina Solar, a maker of solar photovoltaic products, said its net income quadrupled to $32.1 million, or $1.17 per American Depository Share, from the same period of the previous year. These results included a foreign currency exchange loss of $4.9 million. Revenue more than tripled to $290.7 million.

Analysts surveyed by Thomson Reuters, on average, had expected a profit of $1.21 per share on revenue of $276.9 million.

However, the company lowered its full-year 2008 revenue estimate to range between $800 and $850 million because the company expects fewer product shipments for the year than previously forecast.

Shares of Trina Solar fell to a 52-week low of $6.81 Wednesday. The share price is 86.8% lower than a year ago.

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.
