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

• Activision Blizzard Inc. (NASDAQ: ATVI) shares rose after it reaffirmed its full-year earnings and sales outlook.
• Automatic Data Processing Inc. (NASDAQ: ADP) will have low double-digit EPS growth, predicts one analyst.
• AutoZone Inc. (NYSE: AZO) posted a decline in earnings but a small rise in sales, sending shares lower.
• Bed Bath & Beyond Inc. (NASDAQ: BBBY) posted better-than-expected Q2 earnings and higher revenue.
• CarMax Inc. (NYSE: KMX) rallied to a new 52-week high after topping analysts' Q2 earnings expectations.
• Carnival Corp. (NYSE: CCL) reported better-than-expected Q3 results and raised its full-year guidance.

Red Hat (NYSE: RHT), a software business whose colleagues include Microsoft (NASDAQ: MSFT) and Oracle (NASDAQ: ORCL), reported Q2 numbers yesterday after the bell. Today, shares are up quite spectacularly. What's driving all the buying interest?

Well, the results were worthy of praise. Net sales increased 12%. Subscriptions were higher by 15%. Adjusted income, including the elimination of a tax benefit from the total, was 16 cents per share. According to Earnings.com, the market was looking for 15 cents per share. So, we've got the typical beat-by-a-proverbial-penny situation on our hands. I'd rather it be more than a penny, but I'll take it.

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

• Accenture Ltd. (NYSE: ACN) beat earnings expectations but revenue was hurt by currency effects.
• Bed Bath & Beyond Inc. (NASDAQ: BBBY) strong Q1 results beat estimates but same-store sales fell.
• CKE Restaurants Inc. (NYSE: CKR) lower Q1 earnings and strong sales both topped expectations.
• ConAgra Foods Inc. (NYSE: CAG) higher Q4 earnings were in line with expectations, and shares slipped.
• Darden Restaurants Inc. (NYSE: DRI) Q4 results were higher, but it warned of continuing challenges.
• Hennes & Mauritz (OTC: HMRZF) reported strong Q2 numbers, though same-stores sales slipped.

It's far from easy selling enterprise software today. But some companies are finding ways to grow. Just look at Red Hat (NYSE: RHT), which is a leader in open source solutions.

The company's applications, which help to reduce costs and increase productivity, have shown lots of resilience during the recession. For example, according to Red Hat's latest earnings report, the top 25 deals that were up for renewal got renewed. Actually, theses customers increased the commitments by 120%.

First it was Barron's on Monday saying Red Hat (NYSE: RHT), a provider of Linux open-source operating-system software, will likely be in play.

"What makes it strategically important is that it sells the dominant operating system (other than Windows) favored by big corporate users," Barron's Mark Veverka said. The possible interested parties? IBM (NYSE: IBM), Oracle (NASDAQ: ORCL) and Hewlett-Packard (NYSE: HPQ).

Then, today, Jefferis analyst Katherine Egbert supported that argument, saying that it is "inevitable that Red Hat will be subsumed into a larger entity, probably IBM." Egbert reiterated her Buy rating and upped her price target to $21, from $18.

Toyota Motor Corp. (NYSE: TM) slashed its earnings forecast again Monday, the second time in a few months. The Japanese carmaker is now projecting that it would report its first ever operating loss of 150 billion yen ($1.66 billion) for the fiscal year as global demand has declined, especially in the U.S., while the yen has surged. TM shares declined over 3% in premarket trade. TM traded 5% lower by midday trading.

American International Group, Inc. (NYSE: AIG) said Monday it sold its Hartford Steam Boiler (HSB) unit to Germany's Munich Re for $742 million, well below the $1.2 billion AIG paid to acquire HSB in 2000. HSB was one of AIG's most prized businesses. Munich Re will assume $76 million of outstanding capital securities. AIG shares jumped over 5.5% on the news in premarket trade. AIG shares were 4.3% higher by midday.

General Motors Corp. (NYSE: GM) and Chrysler were approved $13.4 billion in bailout funds on Friday from the Bush Administration and another $3.29 billion from the Canadian and Ontario governments for their Canadian subsidiaries. Now, a hard part would be talks with the United Auto Workers union, which are supposed to start in January. Now doubt, they will ask for some tough concessions so that they could present cost cuts and qualify for a second round of loans in February. GM shares declined over 7% in premarket trade. GM shares tanked nearly 17% by midday trading.

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

• Medicis Pharmaceutical Corp. (NYSE: MRX) earnings prospects after a settlement led to an analyst's upgrade.
• Merck & Co. Inc. (NYSE: MRK) lowered its 2009 earnings guidance below analysts' expectations.
• Palm Inc. (NASDAQ: PALM) said that it expects Q2 revenues to come in below analysts' estimates.

Analyst upgrades:

• Calyon downgraded Schlumberger (NYSE:SLB) to Outperform from Buy.

MOST NOTEWORTHY: The U.S. Brokers sector, Goldman Sachs and Research in Motion were today's noteworthy downgrades:

• Goldman downgraded U.S. Brokers to Neutral from Attractive since they can not find a catalyst to move the group significantly higher over the next few months given the continued deterioration in fundamentals. Goldman added Citigroup (NYSE:C) to their Conviction Sell List as they expect additional write-downs of $8.9B in Q2 and see the potential for additional capital raises. Goldman lowered their target price on Citigroup shares to $16 and recommends a pair trade of long Morgan Stanley (NYSE:MS), short Citigroup.
  
• Wachovia downgraded Goldman Sachs (NYSE:GS) shares to Market Perform from Outperform on renewed economic fears, a likely slower pace of substantial capital raises, seasonally slower prime brokerage, and valuation.

Before the bell: Futures lower on financials, tech concerns

Reporting today:
Palm Inc. (NASDAQ: PALM) is expected to post a loss of 22 cents a share in the fourth quarter.
ConAgra Foods (NYSE: CAG) is expected to post earnings of 34 cents a share in the fourth-quarter .

Nike Inc. (NYSE: NKE) reported late Wednesday a rise in quarterly profit of 12% to $437.9 million, or 86 cents a share, helped by gains in Europe and Asia. Sales jumped 16% to $5.1 billion. The earnings beat Wall Street's forecast. Shares are down 4.8% in premarket trading.

Anheuser-Busch Cos. (NYSE: BUD) will likely officially reject InBev NV's $46.3 billion takeover bid this week and announce plans to lower $1 billion in costs, pay a special dividend and sell off divisions like its theme-park unit to increase its stock price. InBev may then raise its offer.

Here's a quick recap of some additional earnings reports on Wednesday.

Beaverton, Ore.-based Nike Inc. (NYSE: NKE) said strong growth overseas helped boost its fourth-quarter profit by 12% to $490.5 million, or 98 cents per share. Analysts polled by Thomson Financial expected the company to earn 96 cents per share for the quarter. Shares fell more than 5% in after-hours trading to $62.15.

CKE Restaurants Inc. (NYSE: CKR) said its first-quarter profit climbed 8% to $16.6 million, or 31 cents per share, helped by a small increase in same-store sales at Carl's Jr. restaurants. Revenue fell 3% to $466.2 million. Analysts polled by Thomson Financial expected profit of 27 cents per share on revenue of $465.5 million. Shares fell 5 cents to $12.25 in after-hours trading.

Sales increased 13% to $3.47 billion beating expectations. The company reaffirmed its guidance for the full year. Shares fell almost 2% to $61.19.

Open source software continues its torrid pace. In fact, according to a report from the 451 Group, the sector saw its biggest quarter for venture funding -- hitting $203.75 million, which is up from $100.4 million in the same period a year ago.

Why the interest? Well, I had a chance to interview Matthew Aslett, who is an analyst of enterprise software at the 451 Group:

Your take on the focus on open source?

VCs are interested in open source vendors because the open source development and distribution models reduce start-up costs and lower the barriers to entry. Some VCs have also cited increased code quality as a reason for investing in open source as the model enables a broader range of product testing and rapid innovation. There are a number of VCs that are sold on the open source model, and some have even stated that they would only consider investing in a software vendor if it was using and producing open source. Open source vendor revenues are lower than more established traditional rivals today, but most vendors are still in their infancy. Recent mergers and acquisitions involving open source vendors such as Zimbra, JBoss and MySQL have proved that the returns are there and are likely to encourage more VCs to look favorably on open source.

As one quarter rolls over into the next, here are some highlights from this past week's earnings coverage from BloggingStocks:

• Best Buy Inc. (NYSE: BBY) beat fourth-quarter expectations and offered a positive outlook for fiscal 2009.
• CarMax Inc. (NYSE: KMX) beat Wall Street earnings estimates for the fourth quarter.
• Citi Trends Inc. (NASDAQ: CTRN) beat fourth-quarter estimates and offered a rosy outlook for fiscal 2009.
• Constellation Brands Inc. (NYSE: STZ) swung to a fourth-quarter loss but beat estimates.
• Family Dollar Stores (NYSE: FDO) beat second-quarter estimates but slashed its full-year outlook.
• Immucor Inc. (NASDAQ: BLUD) beat third-quarter expectations and offered a positive full-year outlook.
• Monsanto Co. (NYSE: MON) beat second-quarter expectations but the full-year outlook disappointed.
• Mosaic Co. (NYSE: MOS) third-quarter earnings surged on strong demand and higher crop prices.
• Paychex Inc. (NASDAQ: PAYX) results on path to continue an 18-year earnings/revenue growth streak.

Also, prospects look grim for some newspapers. The financial crisis in the U.S. prompted the IMF to cut its global growth forecast.

Upcoming results to watch for include Alcoa (NYSE: AA), Circuit City Stores (NYSE: CC), Bed Bath & Beyond (NASDAQ: BBBY), and General Electric (NYSE: GE).

Over the past few weeks, I've talked to a variety of players in the open source world, including people at EnterpriseDB. No doubt, it's a powerful force -- and that's attracting a good amount of venture capital. What's more, companies like Red Hat (NYSE: RHT) have shown that there's money to be made.

But is it possible for a mainstream software company to offer open source? Well, there's no clear-cut answer yet. After all, it's tough to sell a customer expensive software but at the same time offer a free version.

Yet, as history has shown, the software industry can be nimble.

Take Day Software. Based in Switzerland, the company has built a franchise in the content management space. Revenues are growing nicely and the company drops a lot of cash flow.
