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

• CBS Corp. (NYSE: CBS) reported that Q3 revenue was flat while earnings and cash flow declined.
• Clorox Co. (NYSE: CLX) reported better-than-expected Q1 earnings, helped by healthy gross margins.
• Comcast Corp. (NASDAQ: CMCSA) posted better-than-expected Q3 earnings with modest revenue growth.
• Dean Foods Co. (NYSE: DF) Q3 revenue missed estimates but earnings came in better than expected.
• Expeditors International of Washington Inc. (NASDAQ: EXPD) traded lower after its Q3 earnings miss.
• Garmin Ltd. (NASDAQ: GRMN) beat earnings estimates in the week after the Google Navigation launch.

It's a difficult call, but I'm Reiterating my Buy rating for Comcast Corp. (NASDAQ: CMCSA), first recommended on April 22, 2009 at a price of $14.05,

Comcast posted a decent rebound in subscriber growth in Q3, but concerns about intensifying competition in cable television, broadband, and advanced video services persist. In particular broadband competition from telephone/telecom companies, who are offering cheaper DSL services represent the biggest threat. Moreover, as these telecom companies build-out fiber-based video and broadband services, they'll begin to chip away at Comcast's (and other cable companies') conventional cable television services.

Cable giant Comcast (NASDAQ: CMCSA) posted Q3 numbers earlier today. It seems like the company is doing well with earnings growth and cash flow, even if revenues moved up a meager 3%.

Adjusted earnings per share grew over 20% to 28 cents per share. According to our earnings preview, the market was looking for 25 cents per share. Operating cash flow increased a little under 3%, but free cash flow went up almost 20%, aided by a smaller amount of capital expenditures compared to the previous year's similar quarter. I'm sure shareholders are more than satisfied with the growth rate of the green stuff over the past three months. Comcast saw excellent expansion of free cash over the last nine months, too.

Philadelphia-based Comcast Corp. (NASDAQ: CMCSA), which is said to be buying a controlling stake in NBC Universal, is scheduled to discuss its third quarter 2009 financial results in a conference call Wednesday at 8:30 AM ET. You can catch the live webcast of the call on the company's website.

During the three months that ended in September, Comcast launched an internet portal for kids, a collaboration with the NFL, and a trial of On Demand Online. Analysts surveyed by Thomson Reuters expect this leading entertainment, information, and communication provider to report earnings of $0.25 per share, just a penny per share lower than in both the previous quarter and a year ago. Comcast earnings have beat the Street view in the past four quarters, by as much as seven cents per share. Revenue for the third quarter is expected to be 3.5% higher to $8.9 billion.

Is Comcast (NASDAQ: CMCSA) getting ready to buy General Electric's (NYSE: GE) NBC Universal? Hard to say. According to our sister site DailyFinance, it looks like the rumor of this theoretical event might be just that -- a rumor, nothing more. Then again, maybe there's something to it.

It seems likely, though, that Comcast does want to clinch a deal with some big media company. Remember when Comcast wanted to buy Disney (NYSE: DIS)? Quite frankly, it wouldn't surprise me if it ends up taking NBC Universal off GE's corporate hands. But which group of shareholders would this benefit the most?

It's a close call, but I'm Reiterating my Buy rating for Comcast Corp. (NASDAQ: CMCSA), first recommended on April 22, 2009 at a price of $14.05.

Comcast's stock has moved sideways, basically, for the last six months, so a caution flag nevertheless has been raised. The stock has straddled the 50-day moving average during that period, suggesting that institutional investors are concerned about Comcast.

Blockbuster (NYSE: BBI) remains troubled. Just look at the second-quarter report that was released on Thursday after the bell. Net sales dropped over 20%, coming in at roughly $1 billion. The company lost 19 cents per share, one penny better than the loss reported in the year-ago period (to which I say, big deal!). According to the preview, the market wanted to see $1.1 billion for the top line and a loss of only 12 cents for the bottom line. A failure on both counts, I'm afraid.

Cash flow was the more attractive part of the Q2 story. The company calculated its free cash flow to be about $109 million. Okay, I'll give Blockbuster a good mark for having positive cash flow this year.

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

• American International Group Inc. (NYSE: AIG) said its earnings report would not include a conference call.
• Caterpillar Inc. (NYSE: CAT) shares rose after it reaffirmed the 2009 outlook and forecast further growth.
• Cisco Systems Inc. (NASDAQ: CSCO) said its Q4 numbers tumbled despite cost-cutting efforts.
• Comcast Corp. (NASDAQ: CMCSA) posted strong Q2 results, though its cash flow was flat.
• Crocs Inc. (NASDAQ: CROX) reported better-than-expected Q2 results and forecast a return to profitability.
• Electronic Arts Inc. (NASDAQ: ERTS) revenue surged in Q1 and its narrower loss beat expectations.

Comcast (NASDAQ: CMCSA), the high-profile cable and Internet provider, produced some good second-quarter stats on Thursday. Reuters says that the 33 cents per share earned in the period beat estimates by 7 cents. According to the company press release, sales increased over 4% and operating cash flow expanded by over 5%. Free cash flow, however, was flat in Q2.

That wasn't a big deal, though. The free cash covered both the dividend and the monies used to repurchase shares. In fact, Reuters reported that the buyback activity in the quarter represented a resumption of the program. We can take that as a positive sign of confidence from management.

• Infinera (NASDAQ: INFN) was upgraded to Hold from Underperform at Jefferies.

Last week's Fed Beige Book report and GDP numbers suggested that the economy may be stabilizing, and this coming week will bring plenty of economic data to confirm or deny that suggestion. On the schedule are consumer credit, construction spending, factory orders, and pending home sales for June, the employment situation, the Import Price Index, and new motor vehicle sales for July, as well as the ISM Manufacturing and Non-manufacturing Indexes for July.

The week will also bring quarterly reports from home builders Beazer Homes USA Inc. (NYSE: BZH), D.R. Horton Inc. (NYSE: DHI), and Pulte Homes Inc. (NYSE: PHM). Yet again, analysts surveyed by Thomson Reuters expect all three to have narrowed their losses in the most recent quarter. However, they've all tended to post deeper-than-expected losses in recent quarters as well. Analysts also expect to see their revenue down 45% or more for the past quarter. They forecast long-term EPS growth of 7% or more, but none of these homebuilders has a First Call consensus buy recommendation, not surprisingly. Short interest is falling off for Beazer and D.R. Horton, and D.R. Horton and Pulte have been reporting positive cash flow from operations, but all three of them said they had more long-term debt than cash in hand last time around. Mortgage insurer PMI Group Inc. (NYSE: PMI) is likewise expected to report that it narrowed its second-quarter loss.
