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

• Activision Blizzard Inc. (NASDAQ: ATVI) said its Q3 profit declined despite the popularity of Guitar Hero.
• Blackboard Inc. (NASDAQ: BBBB) said Q3 revenue surged and its offered impressive cash flow numbers.
• Boston Beer Co. Inc. (NYSE: SAM) easily beat Q3 earnings estimates and raised its full-year guidance.
• Cisco Systems Inc. (NASDAQ: CSCO) lower Q1 results topped estimates and sent shares higher.
• Cognizant Technology Solutions Inc. (NASDAQ: CTSH) was upgraded following its strong Q3 results.
• Corporate Executive Board (NASDAQ: EXBD) received an analyst's upgrade following the Q3 results.

Activision Blizzard (NASDAQ: ATVI) published third-quarter results on Thursday after the bell. I can't say I was wholly taken with them. I know the best is probably yet to come once the Christmas shopping season really gets under way, but I was a little disappointed that the company saw a decline in adjusted profit.

Excluding items, Activision Blizzard made 4 cents per share this quarter versus the 7 cents per share made in last year's similar period. Well, did I say I was a little disappointed? Make that a lot disappointed. After all, this is supposed to be the publisher with the best pipeline on the block, the one with the Guitar Hero franchise and a great portfolio of licensed intellectual properties.

Analyst upgrades:

• Sierra Wireless (NASDAQ: SWIR) was upgraded at Jefferies to Hold from Underperform following Q3 results. The firm believes the Wavecom acquisition integration is progressing better than expected and finds the valuation attractive at current levels. The firm raised its price target to $10 from $5.
• Boston Properties (NYSE: BXP) was upgraded to Buy from Hold at Deutsche Bank to reflect the company's recapitalization and better-than-expected occupancy. The firm raised its target to $69 from $46.
• Wyndham (NYSE: WYN) was upgraded to Outperform from Market Perform at FBR Capital after the shares sold off following the company's Q3 results. The firm raised its target to $23 from $15.
• Human Genome (NASDAQ: HGSI) was upgraded to Overweight from Neutral at JPMorgan. Target was raised to $25 from $14.
• Urban Outfitters (NASDAQ: URBN) was upgraded to Overweight from Market Weight at Thomas Weisel as they expect a "meaningful sales and earnings improvement in Q4." Target was raised to $39 from $32.
• Methanex (NASDAQ: MEOH) was upgraded to Buy from Neutral at UBS, citing improved methanol demand following the Q3 report. Target was raised to $19.50 from $17.
• Buffalo Wild Wings (NASDAQ: BWLD) was upgraded at Raymond to Market Perform from Underperform.

"The video game industry was once thought to be virtually recession proof; unfortunately, recession reality has intruded," notes Geoffrey Seiler, who adds, "Boosters, however, are pointing to new games scheduled for release later this year as a reason for optimism."

In his always-informative BullMarket.com, the advisors offers an in-depth review of the sector, highlights potential opportunities in GameStop (NYSE: GME), Electronic Arts (NASDAQ: ERTS), and Activision Blizzard (NASDAQ: ATVI).

"When you get right down to it, success in the video game business isn't much different from the movie business: developers are only as good as their last hit game.

Bright and early this morning, Goldman Sachs downgraded gaming guru Activision Blizzard (NASDAQ: ATVI) from Conviction Buy to Buy. In a note to clients, the brokerage firm explained that it sees greater relative potential for near-term price appreciation in other stocks. Goldman maintains a six-month price target of $16 on ATVI, implying expected upside of more than 29% from the shares' closing price on Wednesday.

ATVI is a ripe target for downgrades, if only because analysts are so lopsidedly optimistic toward the "Guitar Hero" parent. Zacks reports that the equity has attracted no fewer than 18 Strong Buy recommendations, plus two Buys -- with not a single Hold, Sell, or Strong Sell to be found.

September is drawing to a close. What does this signify? Well, one of my favorite times of the year, Halloween, will soon be upon us. Even more than that, holiday shopping is about to begin in earnest. Is your portfolio ready?

I've been checking around for investments in the retail sector. Problem is, so many of them have already had significant run-ups. However, even with these higher stock prices, the sector still might be an interesting one to look at since it's possible that Christmas could turn out okay. A post on DailyFinance discusses a report from the International Council of Shopping Centers, which basically states that numbers from this holiday season should see an improvement over last year's data.

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.

It's finally happened. Nintendo (OTC: NTDOY) has reduced the price of its Wii gaming console. What once was $250 is now $200 (or, technically, $199.99, the psychologically important way of designating the new cost).

Why did Nintendo do this? Because both Microsoft (NASDAQ: MSFT) and Sony (NYSE: SNE) have cut the costs of their own entertainment systems. Plus, we're simply at that point in the latest video-game cycle when cuts are implemented. Hardware eventually becomes less expensive. When demand levels fall off, more casual, value-oriented consumers are courted with cheaper prices.

Activision Blizzard (NASDAQ: ATVI) remains confident in its guidance for full-year earnings. According to StreetInsider.com, management is still looking for sales of $4.5 billion on the top line and adjusted earnings of 63 cents per share on the bottom line.

The publisher, which competes with Electronic Arts Inc. (NASDAQ: ERTS), should benefit from recent hardware price cuts made by Sony Corporation (NYSE: SNE) and Microsoft Corporation (NASDAQ: MSFT). With more units in the field, there most likely will be higher demand for Activision Blizzard's awesome pipeline, which includes Call of Duty.

According to GameSpot, execs at Viacom (NYSE: VIA) are pleased with the initial acceptance by consumers for its high-profile game The Beatles: Rock Band. The company said that expectations for the title, which is distributed by Electronic Arts (NASDAQ: ERTS), have been surpassed, and that a quarter of the inventory has already moved off retail shelves. Impressive.

Recently, I wrote an article about The Beatles game and how it might impact the Guitar Hero franchise from Activision Blizzard (NASDAQ: ATVI). I'm a shareholder of the latter, so I'm obviously biased on the subject. I want Rock Band's competitor to win the battle, no question.

The news for video games isn't improving, I'm sorry to say. My colleague Mark Fightmaster recently discussed the disappointing industry sales results observed in the month of August. As he pointed out, total revenues for the sector have now dropped six times in a row.

Oh, that doesn't feel nice at all. I own shares of Activision Blizzard (NASDAQ: ATVI), and I have to admit, the trend does send an icy chill down my spine. But I'll bet shareholders of Electronic Arts (NASDAQ: ERTS) feel even worse. August, of course, is a big month for them. The latest version of the Madden football franchise is released during the latter part of summer. Unfortunately, this year's game seems to have been a disappointment in terms of units sold.

I've been a faithful Activision Blizzard (NASDAQ: ATVI) shareholder for a while now. Sure, I've thought of booking my profits at times, but so far, I've held tight on my long-term position (note: I did do a quick trade with the stock earlier in the summer).

The Guitar Hero franchise is one of the reasons why I keep holding the stock. I figure a lot of units tied to the brand will be sold this holiday season. However, there is a looming threat. Viacom (NYSE: VIA) and Electronic Arts (NASDAQ: ERTS) are set to release The Beatles: Rock Band. The street date is September 9, and analysts will be watching the early sales very carefully to see how the dynamic shapes up.

So you've heard the news I'm sure. Microsoft Corporation (NASDAQ: MSFT) is not standing still in the video-game wars. It recently reduced the price of the Xbox 360 Elite system by $100. We now have parity between an Xbox 360 unit and a Sony Corporation (NYSE: SNE) PlayStation 3 console.

It's going to be interesting to see how hardware sales perform in the coming months. Intuitively, one would have to expect a bump in the number of units sold for both companies. But which one will win out?

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

• Activision Blizzard Inc. (NASDAQ: ATVI) reported better-than-expected Q2 results, sending shares higher.
• Blackstone Group (NYSE: BX) said it swung to a Q2 profit despite a dearth of leveraged buyouts.
• CBS Corp. (NYSE: CBS) Q2 earnings declined but still topped estimates, sending shares higher.
• Coinstar Inc. (NASDAQ: CSTR) reported stellar Q2 results driven by its the popularity of RedBox.
• Clorox Co. (NYSE: CLX) posted solid Q4 earnings but said revenues were flat due to currency effects.
• Duke Energy Corp. (NYSE: DUK) lower Q2 earnings beat expectations by a penny but revenue fell short.

Oh, I am so depressed! I was thinking of buying Activision Blizzard (NASDAQ: ATVI) for an earnings trade, but unfortunately never got around to it. Those who did are pretty happy. The publisher released second-quarter results on Wednesday after the bell, and investors bid the stock over 10% higher today.

Adjusted revenues came in at a little over $800 million. Management's previous guidance called for $775 million to be booked. Adjusted earnings were 8 cents per share, 2 cents ahead of company expectations. According to Reuters, this was a penny better than what the actual analysts were forecasting.
