Santa hasn't even been tugged down Central Park West yet, and Wal-Mart (WMT) is already slashing its prices. The market among major retailers is intensifying, with many offering products as loss leaders in order to entice customers into the store (physical or otherwise) and boost their basket sizes. Along with Target (TGT) and Amazon (AMZN), Walmart is slashing DVD prices, the same tactic it's using with books.

Retailers are rushing to undercut each other this year, which is causing prices to spiral down quickly. When Walmart announced reduced prices on several titles to $10, Amazon followed at $9.99, with Walmart stepping back in at $9.98.

Analyst upgrades:

• Bernstein upgraded General Electric (NYSE: GE) to Outperform from Market Perform Thursday after the close. The firm sees an improved risk/reward on the stock and raised its price target to $19 from $18.
• Bernstein also upgraded Amazon.com (NASDAQ: AMZN) to Outperform from Market Perform as it believes sales growth and margin expansion expectations are too low. The firm raised its target on shares to $160 from $125.
• Piper Jaffray upgraded CBS (NYSE: CBS) to Neutral from Underweight following the company's Q3 results and raised its target on shares to $13 from $12.
• JPMorgan upgraded Macy's (NYSE: M) to Overweight from Neutral to reflect the company's improving comps. The firm has a $23 target on the stock.
• Ansys (NASDAQ: ANSS) was upgraded to Buy from Hold at Jefferies.

• Air Methods (NASDAQ: AIRM) was upgraded to Overweight from Equal Weight at Stephens.

While eBay (NASDAQ: EBAY) has been working hard to manage its marketplace in a trying economy, its PayPayl business has been growing comfortably and could become the company's biggest earner. For the past two years, eBay has focused on improving the look of its website and helping buyers and sellers to get along in a virtual world built entirely on trust.

In the background, though, the segment of the business that moves money from Point A to Point B has been on fire. Even with payment processing competition from Amazon (NASDAQ: AMZN) and Google (NASDAQ: GOOG), PayPal has been able to do more than hold its own.

Best Buy (NYSE: BBY) may be the world's largest electronics retailer, but it realizes that it faces a huge threat to a hefty chunk of its business. Apple (NASDAQ: AAPL) is moving plenty of movies and other soon-to-be former DVD fare through iTunes, staking a claim on a business that once belonged to Best Buy. The big box store is getting ready to fight back (finally?).

Using technology it's licensing from Sonic Solutions (NASDAQ: SNIC), Best Buy is opening an online store for movies and television shows. Best Buy CEO Brian Dunn says this move will expand the company's presence in services and will bolster company loyalty. That's the press release version, of course. The reality is that Best Buy needed to do something to protect this portion of its revenue and probably should have made the move several years ago.

Two of the newsletter industry's leading growth stock advisors remain bullish on the prospects of online retailer Amazon.com (NASDAQ: AMZN), based on growth in not only online retailing but new market areas ranging from the Kindle e-reader to cloud computing.

Mike Cintolo, editor of The Cabot Top Ten Report, explains, "Amazon.com recently blew away earnings expectations." Meanwhile, Alexander Green, investment director at The Oxford Club, says, "In our view, the best lies ahead for the company." Here are their reviews.

Mike Cintolo continues, "Amazon announced that its Kindle e-book reader is now its most popular selling item, both in units and in dollars. That led to a big acceleration in revenue growth (28%, the fastest in five quarters), while earnings leaped 67%.

Small book retailers were buying in bulk from major online booksellers because they could really save some money. One was buying up to 70 copies of a particular title -- it was $5 less a pop from the big guys than it would have been from the publisher. Finally, however, the big retailers have become wise to the trend and taken action, according to the Wall Street Journal (subscription required).

Wal-Mart (NYSE: WMT), Amazon (NASDAQ: AMZN), and Target (NYSE: TGT) have decided to cap the number of books customers can buy online, a measure intended to prevent smaller competitors from treating them as partners. Walmart is limiting customers to two copies of a particular book, with Amazon placing the border at three and Target at five.

Today started out higher for stocks, but then the US Peso came into play. Shares have been the beneficiary of a weakening dollar, but then the currency bears started to cover the position. There is talk that some foreign central banks intervened to halt the rise of their own currencies, although whether or not that was the case may not be known.

Here were today's unofficial closing bell levels:

Dow 9,867.81 -104.37 (-1.05%)
S&P 500 1,066.98 -12.62 (-1.17%)
Nasdaq 2,141.85 -12.62 (-0.59%)

Barnes & Noble Inc. (NYSE: BKS) recently announced an electronic e-reader to compete with the likes of the Amazon.com's (NASDAQ: AMZN) Kindle and Sony Corp.'s (NYSE: SNE) Reader.

In perfect holiday fashion, the e-reader is set to become the "must have" gadget for the gift-giving season almost upon us. The newer Nook device has a small color screen that allows easier content locating (but no keyboard), the ability to "lend" digital books to a friend and built-in wireless internet.

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

• AirTran Holdings Inc. (NYSE: AAI) reported its third consecutive quarterly profit and will increase capacity.
• Amazon.com Inc. (NASDAQ: AMZN) shares soared after it reported very strong Q3 numbers.
• Apple Inc. (NASDAQ: AAPL) reported stellar Q4 results, driven by the popularity of Macs and iPhones.
• BlackRock Inc. (NYSE: BLK) Q3 earnings soared, due in part to a tax benefit, and assets managed grew.
• Broadcom Corp. (NASDAQ: BRCM) revenue surged sequentially but note the would be flat going forward.
• Caterpillar Inc. (NYSE: CAT) beat Q3 earnings expectations and shares rose though revenue slumped.

This was the day that could have been. Earnings were coming out favorably, yet the data just couldn't support the stocks. There were also trader comments that BofA/Merrill had large sell orders or sell programs throughout the day. It looks like the DJIA even closed out under the 10,000 mark on an unofficial basis.

Here were today's unofficial closing bell levels:

Dow 9,974.75 -106.56 (-1.06%)
S&P 500 1,079.73 -13.18 (-1.21%)
Nasdaq 2,154.47 -10.82 (-0.50%)

Analyst initiations:

• Allegheny (NYSE: AYE) was initiated with a buy at Citigroup as attractive at current levels. Target is $33.

• FirstEnergy (NYSE: FE) was initiated with a Buy at Citigroup who believes the company's current valuation doesn't reflect its transition to full market-based rates in 2011. Target is $56.

Amazon (NASDAQ: AMZN), simply put, had a quarter to die for, the kind that all shareholders have on their wish lists. The Q3 numbers, which were released on Thursday after the bell, speak for themselves. Net sales: up 28%. Operating income: up 62%. Per-share profit: up 67% to 45 cents. Free cash flow for the trailing twelve months: up 98%. Yep, Amazon's fundamentals seem to be heading in the right direction.

According to our earnings preview, Wall Street was on record as wanting to see 33 cents per share on the bottom line. Amazon's management did a fine job of supplying further evidence to the market that the company's online business model is not only here to stay, but that it should provide shareholders with a significant amount of value over time.

Target Corp. (NYSE: TGT) was a crown jewel in the retail world in 2008. It was seen as a more upscale and clean alternative to Wal-Mart Stores Inc. (NYSE: WMT) but with the same discount strategy. It was winning customers for most of last year.

Then the economy went south (almost to the South Pole). Customers immediately flocked to save as much money as possible and obtain everyday staples as cheaply as they could. Target got whacked by reality. It's been playing catch-up to Wal-Mart ever since.

After the closing bell on Thursday, internet retailer Amazon.com (NASDAQ: AMZN) will step into the earnings spotlight. Experts believe that Amazon will report third-quarter earnings of 33 cents per share with revenue of $5.03 billion. Amazon forecast third-quarter revenue of $4.75 billion to $5.25 billion. In last year's third quarter, Amazon earned 27 cents per share with revenue of $4.26 billion.

With the economy struggling, what should we expect from Amazon? Reportedly, ThinkEquity saw traffic data that implies Amazon's unique visitors rose 23% in the latest quarter. If this is the case, the retailer's sales should have received a bit of a push in the quarter, which could lead to higher earnings. In fact, the ThinkEquity analyst (Ed Weller) told the Associated Press that he expects Amazon to report earnings of 35 cents per share on revenue of $5.13 billion.

Online auction giant eBay (NASDAQ: EBAY), a business that counts Amazon (NASDAQ: AMZN) and Yahoo! (NASDAQ: YHOO) as related companies, was not popular in Wednesday's after-hours session. The third-quarter report just didn't do it for Wall Street, so Wall Street decided to make some trouble and bring the per-share price of the stock down by 4.5%. Oh sure, the company beat earnings by the most famous amount there is -- the proverbial penny -- but, according to this Bloomberg piece, guidance was not so inspiring.

The top line was actually pretty cool. Net sales saw an increase of 6%. Unfortunately, the bottom line couldn't take advantage of such growth. On an adjusted basis, net income dropped 16% to 38 cents per diluted share. And, as I just said, that was one penny ahead of the analysts.
