Retailers appear to have been rescued at the last minute, according to data from the International Council of Shopping Centers. Shoppers looking for deals the week before Christmas -- and making up for the day lost to stormy weather on the East Coast -- spent aggressively, sparing the retail sector a dismal 2008-like performance.

The healthy conclusion to the holiday season led to a positive change from November and made December one of only three months (including September and October) in which retail sales increased year-over-year.

Retail sales results are pouring in, and one of the companies finding itself on the smiling side of the data is Costco (COST). The warehouse club reported that higher gas prices and a weak dollar helped a "key sales figure" increase 9% during December. The Street expected Costco to report an increase of 7.9%. Removing higher gasoline prices and the soft dollar from the equation resulted in a sales increase of 4%. U.S. sales increased 2% and international results increased 10%.

Costco (and other warehouse stores) turned in a solid month, as shoppers looked to stretch their dollar as far as possible. When you can go into a store and purchase 50 toilet paper rolls for a reasonable price, why wouldn't you shop at a bulk retailer?

This week, the world's top retailers will tell investors how the much-discussed holiday season went. Analysts expect a year-over-year gain of 1.3% for stores open at least a year, which of course uses a dismal 2008 as a benchmark.

The holiday shopping season is the last chance retailers get to pump up their financial statements before the close of their fiscal year, which usually comes at the end of January. For some retailers, up to 40% of their revenue comes in the weeks heading into Christmas.

Food stamps are pumping up revenue at retailers across the country. Costco (COST), Wal-Mart (WMT) and others are seeing rushes an hour before funds are credited to electronic benefits transfer cards. Wal-Mart's CFO, Tom Schoewe, has noted the trend, telling Reuters, "Once the clock strikes midnight [on the last day of the month] and EBT cards are charged, you can see our results start to tick up."

Spending via EBT is not only increasing, it generally happens quickly. JPMorgan (JPM), which runs EBT programs for more than 20 states, reports that buyers run through 85% of food stamp funds within the first three days of their availability.

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

• Advance Auto Parts Inc. (AAP) was downgraded due to concerns about its 2010 earnings outlook.
• Analogic Corp. (ALOG) received an analyst's downgrade after it reported weaker-than-expected earnings.
• AutoZone Inc. (AZO) strong Q1 results beat earnings expectations, but shares rose only a little.
• BWAY Holding Co. (BWY) received an analyst's upgrade following release of its Q4 results.
• Casey's General Stores Inc. (CASY) topped Q2 earnings estimates but lower revenue fell short.
• Ciena Corp. (CIEN) shares plummeted after it fell short of its earnings expectations for Q4.

Costco (COST), a warehouse club that competes with BJ's (BJ) and Wal-Mart (WMT), reported Q1 numbers on Thursday. Earnings, which came in at 60 cents per share, were flat compared to last year's results. Not only that, but expectations were precisely met. Not exactly an exciting quarter, huh?

Total sales rose 6%, but same-store sales -- the more important statistic as it paints a better picture of the overall health of a retail business by indicating how well older stores are maintaining their growth characteristics -- increased 3%, excluding currency and fuel transactions.

Costco Wholesale Corp. (COST), the nation's largest largest wholesale club operator, is scheduled to discuss its financial results for the fiscal first quarter 2010 in a conference call Thursday, December 10, at 11:00 AM (ET). Speakers include CFO Richard A. Galanti. You can catch the live webcast of the call on the company's website.

The three months that ended in November saw Costco report strong monthly sales and declare a quarterly dividend. Analysts surveyed by Thomson Reuters expect Costco to report that its earnings fell a nickle per share from a year ago to $0.60 per share. But revenue for the quarter is expected to total $17.3 billion, 5.6% higher than a year ago.

Sluggish retail sales in November didn't stop retailers from adding bodies. A report by outplacement consulting company Challenger, Gray & Christmas, reavealed to BloggingStocks, shows that retail sector payrolls grew to 321,300 in November, an improvement from the previous month's 233,700. This follows 54,200 retail hires in October, bringing the total number of seasonal retail employees up to 375,500. Already, that comes close to the 384,300 hired from October through December in 2008. The analysis is based on data supplied by the Department of Labor.

High expectations for the holiday season likely contributed to the up-tick in hiring. The estimated 0.5% growth from Black Friday 2008 to Black Friday 2009 was a disappointment, and November sales were off 0.3%, surprising analysts, who expected the trend to go in the other direction. Costco (COST) and Limited Brands (LTD) came out ahead, but most retailers, including Target (TGT) and Macy's (M) struggled. Saks (SKS) is also suffering from an anemic luxury goods market.

The earnings season, like the calendar year, is winding down. The sprinkling of quarterly results scheduled for this coming week include S&P 500 components AutoZone (AZO), Ciena (CIEN), H&R Block (HRB) and National Semiconductor (NSM), as well as Dollar General (DG), Imperial Sugar (IPSU), Krispy Kreme Doughnuts (KKD), Men's Wearhouse (MW), Talbots (TLB) and others.

Analysts surveyed by Thomson Reuters expect to see strong year-over-year and sequential EPS growth from luxury watchmaker Movado Group Inc. (MOV). During its third quarter of fiscal 2010, this Paramus, N.J.-based company was recognized for its innovative use of technology and it reported a big profit decline for the second quarter.

Two months of momentum and Black Friday weren't enough to make November a winner for retailers. The holiday shopping season kickoff was up only 0.5% year-over-year, and the month as a whole saw retail sales fall 0.3% year-over-year. As if the drop weren't bad enough, it's a decline on top of last year's November retail freefall, which means we went from bad to worse.

Meanwhile, analysts had expected a strong increase. U.S. government data on retail sales isn't due to be reported until December 11, 2009, and it's expected to be a better indicator of the sector's performance. The data released Thursday doesn't include sales by Wal-Mart (WMT).
