Barnes & Noble, the Gap, RadioShack, and Sears -- that may sound like the lineup at the local mall, but in fact they are just a few of the retailers scheduled to step into the earnings spotlight this week. Following last week's disappointing January retail sales numbers from the Commerce Department but strong fourth-quarter reports from Abercrombie & Fitch (ANF) and Nordstrom (JWN), the coming week will offer plenty more data on the sector for investors to mull over.

Walmart

Bentonville-based Walmart (WMT) offered free holiday shipping, closed its Moscow office and named a chief merchandising officer during its fourth quarter. Analysts surveyed by Thomson Reuters forecast earnings for that period to come to $1.31 per share, up from $1.17 in the same quarter of last year. The world's largest retailer also is expected to post revenues of $117.7 billion for the three months that ended in January. That's 3.5% more than a year earlier.

A slight economic upgrade from the Federal Reserve met higher commodity and higher equity prices today. The reality is that most equity markets were up around the globe today as investors are getting more of an appetite for risk. Even a Freddie Mac outlook for 2011 with higher interest rates and a 'narrower' budget deficit of $80 billion in December failed to temper optimism.

Here are the unofficial closing bell levels:

Dow Jones 11,755.44 +83.56 (0.72%)
S&P 500 1,285.96 +11.48 (0.90%)
Nasdaq 2,737.33 +20.50 (0.75%)

• Campbell Soup Co. (NYSE: CPB) reported solid Q2 numbers despite competition from store brands.
• DreamWorks Animation SKG Inc. (NYSE: DWA) missed Q4 expectations, sending shares lower.
• First Solar Inc. (NASDAQ: FSLR) said Q4 profit more than doubled due to strong demand.
• Garmin Ltd. (NASDAQ: GRMN) posted a lower-than-expected profit on soft sales and lower margins.
• Heidrick & Struggles International Inc. (NASDAQ: HSII) earnings and revenue declined in Q4.

Yesterday, struggling jewelry retailer Zale Corp. (NYSE: ZLC) announced the closure of 115 stores in a drastic cost-reduction plan. The company also announced that revenue dropped nearly 18% in the second quarter.

The stores designated for closure will lock their doors for good when their leases mature. The closing stores are poor sales performers. In addition, ZLC announced that it will cut its capital spending by 65%, along with 245 jobs already cut this month. Furthermore, the jeweler plans to reduce its debt by roughly $40 million from the end of the second quarter through July (which is the end of ZLC's fiscal year). ZLC noted that the addition of Canadian and Puerto Rican assets give the company flexibility and sufficient liquidity.

If you made a bet on the specialty retailers leading up to the first $600 taxpayer rebate stimulus package, you got hammered.

Talk about a government plan backfiring big time.

That $300 billion in checks that fell out of the sky from government helicopters back in the March to May timeframe didn't find its way to the malls at all.

Instead, people paid down credit card debt, and tuition, medical and other bills, leaving little for spending on non-essentials.

The result was a litany of store closings nationwide, with several old-line, brand-name retailers going out of business.

It's game over for names like Circuit City (OTC: CCTYQ), Cache (NASDAQ: CACH), Talbots (NYSE: TLB), J. Jill, Wickes Furniture, Levitz, Bombay, Linens 'n Things, Movie Gallery, Wilson Leather, KB Toys and The Sharper Image.

Traders that leveraged into darling names, like hedge fund idol Eddie Lampert's Sears Holdings Corp. (NASDAQ: SHLD), got smoked. Shares of SHLD were trading at $105 when the checks when out. Today the stock is around $40.

Even Costco (NASDAQ: COST) -- the obvious slam dunk, aside from Wal-Mart (NYSE: WMT) -- got slammed, falling from $75 to $45 following the so-called stimulus package.

The earnings season is beginning to wind down as we have passed the halfway mark of the quarter and the holiday season begins in earnest next week with Thanksgiving in the United States.

Bermuda-based Frontline Ltd. (NYSE: FRO) is anticipated by analysts surveyed by Thomson Reuters to be one of the biggest earnings gainers among companies scheduled to report quarterly results this coming week. The oil tanker fleet operator is expected to post third-quarter earnings of $1.97 per share, 86.8% higher than in the same period a year ago, on revenues of $399.5 million (+44.6%). Frontline missed estimates by 6.4% in the previous quarter, and the consensus recommendation by analysts is to hold FRO. While Motley Fool likes its robust dividend, Jim Cramer said in a recent Lightning Round that he prefers rival Nordic American Tanker Shipping Ltd. (NYSE: NAT). Shares have fallen 52.9% in the past three months, and reached a 52-week low of $25.00 on Friday.

Analog Devices Inc. (NYSE: ADI) is also expected to be among the week's biggest earnings gainers. Analysts are looking for the semiconductor chip maker to report a fiscal fourth-quarter profit of $0.44 per share, 31.8% higher than a year ago, on revenues of $661.7 million (+2.0%). Analog Devices has beat estimates in three of the past five quarters, but only missed by 1.3% in the previous quarter. Analysts on average recommend buying ADI, which has a forecast long-term EPS growth rate of 17.3%, which better than the S&P 500 and that of rival Texas Instruments Inc. (NYSE: TXN). Shares sank to a multiyear low of $16.23 on Friday, and are down 41.1% in the past three months.

Zale Corporation (NYSE: ZLC) is a specialty retailer of fine jewelry, operating over 2,100 retail locations throughout the United States, Canada and Puerto Rico. Company brands include Zales Jewelers, Zales Outlet, Gordon's Jewelers, Peoples Jewellers, Mappins Jewellers and Piercing Pagoda. The firm also operates Zales and Gordon's websites. Wal-Mart (NYSE: WMT) is a major competitor.

The firm surprised investors late last month, when it reported a Q4 loss of 48 cents and revenues of $456.2 million. Analysts had been looking for a loss of 57 cents and $448.9 million. There was a 6.1% year over year increase in Q4 comparable store sales. Management also guided FY09 EPS to $1.10-$1.25, versus Street consensus of 90 cents. The CEO spoke of implementing programs designed to simplify product assortment and eliminate organizational redundancies.
