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

• AK Steel Holding Corp. (NYSE: AKS) reported better-than-expected Q3 results but shares fell anyway.
• Baidu Inc. (NASDAQ: BIDU) posted strong Q3 results but shares sold off on a disappointing guidance.
• Burger King Holdings Inc. (NYSE: BKC) said lower Q1 earnings fell short of analysts expectations.
• Dreamworks Animation SKG Inc. (NYSE: DWA) topped Q3 profit and revenue estimates, lifting shares.
• Geron Corp. (NASDAQ: GERN) posted a narrower-than-expected Q3 loss, sending shares sharply higher.
• Honda Motor Co. Ltd. (NYSE: HMC) reported lower Q2 earnings and sales on weak demand for cars.

Today was potentially a pivotal day. There was a technician calling for a possible peak in the S&P and that was partly on yesterday's dollar strength. Then came the disappointing consumer confidence data. Amazingly, we had a very mixed market close picture today depending on which group of stocks you were looking at.

Here were today's unofficial closing bell levels:

Dow 9,882.17 +14.21 (0.14%)
S&P 500 1,063.41 -3.54 (-0.33%)
Nasdaq 2,116.09 -25.76 (-1.20%)

LDK Solar Co., Ltd. (NYSE: LDK) was broadly higher Tuesday after boosting its top-line guidance for the third quarter. The alternative energy issue now anticipates revenue of $270 million to $290 million for the period, compared to its earlier forecast for $240 million to $270 million. Analysts' consensus expectations call for third-quarter revenue of just $249.9 million, according to Thomson Reuters.

LDK added that it now expects wafer shipments for the third quarter to range between 310 megawatts (MW) and 330 MW, up from its previous view of 260 MW to 300 MW. Simultaneously, the firm dropped its forecast for module shipments -- instead of 10 MW to 20 MW, LDK is now looking for module shipments of 5 MW to 10 MW.

After the closing bell sounds this afternoon, LDK Solar (NYSE: LDK) will report quarterly earnings. Expectations are pegged at a loss of 91 cents per share for the solar firm, so what can you expect in the wake of the report? Let's take a look at LDK's technical prospects and what an earnings miss or stronger-than-expected earnings could do for the company.

First things first, LDK manufactures and sells solar wafers to other solar manufacturers, both in China (the company's home) and across the globe. The company performed well in the past, when the new global conscience had companies and individuals looking for cleaner forms of energy. Unfortunately, this little thing called a recession occurred, pulling many customers away from LDK and hurting the company on the bottom line.

LDK Solar (NYSE: LDK - option chain) stock is falling today after the company announced a weak forecast for Q2 revenue last Thursday after the close. Today's weakness in oil futures is also not helping LDK stock. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on LDK.

This morning, LDK opened at $10.20. So far today the stock has hit a low of $9.66 and a high of $10.52. As of 12:15, LDK is trading at $9.87, down $1.04 (-9.5%). The chart for LDK looks bearish and S&P gives LDK a negative 2 STARS (out of 5) sell ranking.

Stocks opened up on the day and stayed up on the day, despite closing well off of the highs. We had three key economic reports hit at once as the Institute for Supply Management gave the June ISM Manufacturing data, while we saw pending home sales data and new construction spending data mixed for May. These actually ended up being contradictory numbers, and then the oil inventories did nothing to support higher oil prices.

Here were today's unofficial closing bell levels:

Dow 8,504.06 +57.06 (0.68%)
S&P 500 923.33 +4.01 (0.44%)
Nasdaq 1,845.72 +10.68 (0.58%)

Today was a day marked by selling, partly on economic news and partly on a call from S&P. S&P put the credit bias of the United Kingdom at "negative" from "stable" giving the notion that the nation's Triple-A ranking is possibly at risk to be cut. Then came the implications from Bill Gross and others that the U.S. could ultimately see the same fate. To show how bad the trend and bias was, long-dated Treasuries saw their yields rise as much as 15 basis points today.

A slightly less-bad jobs report failed to catch any attention today. In short, if you are a market bear you are getting more feathers in your cap now that earnings are basically finished. Here are today's unofficial closing bell levels:

Dow 8,291.82 -130.22 (-1.55%)
S&P 500 888.23 -15.24 (-1.69%)
Nasdaq 1,695.25 -32.59 (-1.89%)

Chinese solar firm LDK Solar (NYSE: LDK) reported earnings Wednesday, revealing that a massive writedown caused weaker-than-expected earnings. LDK reported a fourth-quarter loss of $1.25 per share, compared to a gain of 77 cents per share in the previous quarter and earnings of 44 cents per share in the same quarter last year.

The company's revenue increased more than twofold compared to last year, but the $426.6 million was 21.3% lower on a sequential basis. Analysts were expecting a loss of 84 cents per share on revenue of $422 million. The quarterly results took a hit of $216.7 million related to an inventory writedown.

Today's markets were under pressure most of the day after weekly jobless claims remained higher than estimates and after wholesale inflation rose more than expected. Earnings disappointments also added some pressure, yet oil rose sharply today with futures up over 10% at $38.60 late in the day after oil inventory levels were reported. Here are today's unofficial closing bell levels:

Dow 7,465.79 -89.84 (-1.19%)
S&P 500 778.93 -9.49 (-1.20%)
Nasdaq 1,442.82 -25.15 (-1.71%)
