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

• Aflac Inc. (AFL) posted better-than-expected Q4 earnings, though revenue fell short, and offered rosy guidance.
• Avon Products Inc. (AVP) posted Q4 earnings growth that met analysts' expectations but shares sold off.
• Cisco Systems inc. (CSCO) higher Q2 earnings topped the consensus estimate but cash flow fell.
• CME Group Inc. (CME) fell short of analysts' Q4 profit expectations, resulting in price-target cuts.
• ExxonMobil Corp. (XOM) posted better-than-expected Q4 earnings and revenue that boosted shares.

A late day rally kept the fear mongers from winning hand over fist today. We were down as much as 160 points and a buying spree came in rapidly. The 9.7% unemployment left more questions when you consider that the jobs creation lost another 20,000 jobs. Today's late-day rally seemed like bargain hunting at the end of the day or short sellers closing out of positions ahead of the weekend after big selling all week. The huge loss that it looked like was suddenly a day where the positive or negative close was not going to known until the final minutes.

Here were today's unofficial closing bell levels:

Dow 10,012.23 +10.05 (0.10%)
S&P 500 1,066.18 +3.07 (0.29%)
Nasdaq 2,141.12 +15.69 (0.74%)

Cisco Systems, Inc. (CSCO), an expert in networking, posted Q2 results on Wednesday after the bell. Judging by the data, the tech company is holding up okay.

The top line saw an increase of 8%. Net income came in at 40 cents per share, a 25% jump compared to the year-ago number. According to our earnings preview, 35 cents per share was the figure to beat. Score one for management.

U.S. stock futures were lower Thursday following declines in overseas markets as worries about Europe's sovereign debts resumed. Despite Cisco Systems' upbeat report concerns about the economic recovery ahead of the jobs report continued to affect investors' sentiment.

Already on Wednesday, several weak economic readings, including a service sector gauge, and disappointing results from Pfizer (PFE) pushed stocks lower. But Wall Street is bracing for the nonfarm payroll report due out Friday morning to get a better feel for the state of the economic recovery and employment.

Cisco Systems Inc. (CSCO), whose CEO is optimistic about economic recovery, is scheduled to discuss its second-quarter fiscal 2010 financial results in a conference call Wednesday, Feb. 3, at 4:30 PM (ET). A live webcast of the call will be available at the company's website.

During the three months that ended in January, Cisco completed an acquisition, demonstrated new technologies at CES and announced some organizational changes. Analysts surveyed by Thomson Reuters are looking for earnings for that period of 35 cents per share. That compares with 36 cents per share in the previous quarter and 32 cents per share a year ago. Revenue for the second quarter is expected to be 3.5% higher than a year ago to $9.4 billion.

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

• Apple Inc. (AAPL) posted its highest quarterly revenue ever, easily beating estimates, as iPhone sales doubled.
• Boeing Co. (BA) swung to a larger-than-expected Q4 profit but guidance fell short of analysts' estimates.
• Chevron Corp. (CVX) fell short of analysts' earnings estimates for Q4, sending shares lower.
• Cisco Systems Inc. (CSCO) shares rose after optimistic statements by the CEO ahead of Q2 results.
• Eastman Kodak Co. (EK) shares surged after it beat Q4 expectations by a wide margin and cash flow improved.
• Ford Motor Co. (F) reported its first annual profit in four years due to cost-cutting and improved market share.
• Halliburton Co. (HAL) reported lower Q4 earnings but beat estimates by a penny, and revenue also fell.

Cisco Systems (CSCO - option chain) shares are rising today after company CEO John Chambers said in an interview that tech companies often are among the first to see gains in a recovering economy as businesses upgrade their technology. This could be a good sign for the company, which is scheduled to report Q2 earnings on Wednesday evening. Analysts are looking for the company to post a profit of 35 cents per share on revenue of $9.4 billion, compared to a profit of 32 cents per share on revenue of $9.09 billion in the year-ago period. A good quarter announced last night by competitor Juniper Networks (JNPR) also bodes well for Cisco next week. 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 CSCO.

A new book, The Prince of Silicon Valley, chronicles the dealmaking of the IPO king of the 1990s: Frank Quattrone. He made a fortune as he helped more than 100 tech companies go public, which included marquee names like Cisco (CSCO), Netscape and Amazon.com (AMZN).

But those days seem quaint. In fact, the tech IPO market has been a backwater for the past decade, even though there have been some big deals -- like the offerings of Google (GOOG) and Salesforce.com (CRM).

Today was effectively a boring day in the stock market. At least there was a real index level change. The major overseas markets were all lower, and that sealed the direction for Tuesday. The yo-yo in the dollar and overall demand issues have oil lower and gold lower yet again today.

Here were today's unofficial closing bell levels:

Dow 10,285.59 -104.52 (-1.01%)
S&P 500 1,092.02 -11.23 (-1.02%)
Nasdaq 2,172.79 -16.82 (-0.77%)

Hewlett-Packard (HPQ), the famous maker of printers and PCs, and a colleague of entities such as Microsoft (MSFT), Dell (DELL), and International Business Machines (IBM), issued Q4 results on Monday after the end of the trading day. Revenues didn't impress me, as sales saw a decline of 8%. Net income, however, was better. On an adjusted basis, earnings per share increased 11% to $1.14.

Also doing well was the operating margin. The adjusted metric increased 170 basis points during the quarter. The annual statement of cash flows should look good to any long-term shareholder. Management still had cash left over from operations after share repurchases, dividend obligations, and capital spending.

Amazon, Inc. (AMZN) is in the clouds. So are Google, Inc. (GOOG), EMC (EMC) and Cisco (CSCO). Now, Microsoft Corporation (MSFT) is joining them, having announced on Tuesday its new Windows Azure cloud computing system. The new product will be released on January 1, 2010 -- a new solution for a new year.

Azure will deliver an online platform for the software development set to build their own mousetraps and provide plenty of storage space for users. Testing began a year ago, and full live version will be celebrated next year. For the first month, Azure will be free. The charges start in February.

Today was another up-day that started out strong and stayed strong. Retail sales helped trump a weak NY Fed manufacturing number, and Ben Bernanke said he sees no asset bubbles in the US markets today.

The Street.com's Jim Cramer says that OPEC may take oil out of the equity-market equation and make stock-picking matter again.

If OPEC says it likes an oil price in the $75-78 range, as it said today, we could be looking at a nirvana moment for stocks. We know that any time oil bounces, the S&P 500 futures go up. Any time it goes down, the S&P futures go down. But if OPEC wants to keep it right here, we take oil out of the equation and make stock-picking matter again.

Right now, the Saudis are telling the big oil-shipping companies that they want to bring 1 million barrels a day into the market straight away to keep oil below $80. That can be used to overwhelm the speculators who are tying up as much as 20% of the oil fleet in the world to keep oil off the market and buoy its price. But they will not bring the oil to the market below $75.

When Robert Metcalfe invented Ethernet, he knew it would be an explosive business. So, he co-founded 3Com (COMS) back in 1979. It would become a pioneering company.

But now 3Com will no longer be independent. That is, the company is selling out to Hewlett-Packard (NYSE: HPQ) for $2.7 billion in cash or $7.90 per share.

The deal is definitely a bold move. But HP needs to be aggressive with M&A to continue its growth.

Back in 1981, Logitech (LOGI) began selling computer mice. It was excellent timing. Now, the company is the dominant player in the market for peripherals.

But to continue the growth, Logitech has been expanding into new categories. One of the biggest is video conferencing. In fact, Logitech has announced that it will pay $405 million for LifeSize Communications, which is a major player in the market.
