Aeropostale (NYSE: ARO), a retailer whose colleagues include Abercrombie & Fitch (NYSE: ANF), Pacific Sunwear of California (NASDAQ: PSUN) and Gap (NYSE: GPS), issued its Q2 report on Thursday. The stock didn't do much after the numbers were made public despite reporting a very nice 21% increase in sales during Q2, and a whopping 63% jump in earnings per diluted share to 31 cents. Why such a blasé reaction? Well, the retailer was only able to match the expectations of Wall Street analysts, so that might offer some justification for the lack of a decisive bid.

I felt the same way after reading Aeropostale's earnings release as I did after perusing the stats behind GameStop's (NYSE: GME) recent quarter, thinking the company deserved at least a little excitement, especially when one considers that last year at this time, the mall chain saw a 4% contraction in same-store sales. Of course, there is one understandable difference between the GameStop situation and the Aeropostale scenario. GameStop's stock wasn't trading near a 52-week high, and Aeropostale's shares are. So, perhaps the market is perceiving that a lot of the good news is already priced in.

Aeropostale has done well this year. Its stock is up over 28%. Should that concern potential investors? Perhaps. After all, this is a mall retailer based on fashion and investors must consider that Aeropostale's current hot streak could cool. If that happens, the stock might end up retreating back to the lower end of its 52-week range. While there are any signs that such a retreat will happen, I only want to throw into the discussion the concept of fickleness among the youth.

If you really like Aeropostale and want to buy its stock, it might not be so bad to wait for a better price, in my opinion, to allow at least a little margin for error.

U.S. stock futures were higher this morning, pointing to a potential positive start on Wall Street. Investors this morning await Federal Reserve Chairman Ben Bernanke speech on financial stability scheduled for 10:00 a.m. from the Fed's annual retreat at Jackson Hole. In the face of recent financial turmoil, namely talk of a government bailout for Fannie and Freddie, as well as troubles at Lehman, Bernanke's speech will likely be today's highlight. Meanwhile, oil dropped a little from Thursday's advance.

Indeed, the Wall Street Journal reports that Freddie Mac (NYSE: FRE) "executives are sounding out private-equity firms and other investors about the possibility of buying new common or preferred shares in the mortgage company."

Even Warren Buffett opined on the matter on CNBC this morning, saying he expects the government to take action to support troubled mortgage financiers.

Rival home improvement chains Home Depot Inc. (NYSE: HD) and Lowe's Companies Inc. (NYSE: LOW) are scheduled to report quarterly results this week.

For Home Depot, that's 61 cents per share, down 20.8%, and for Lowe's, 56 cents per share, down 16.4%. Meanwhile, cabinet maker American Woodmark Corp. (NASDAQ: AMWD), for whom Home Depot and Lowe's are major distributors, is also expected to report lower earnings: 11 cents per share, down 67.6%.

With recession fears, housing market worries and credit concerns, retailers have been facing tough times, especially during the holiday winter season of December and January when sales came with weak numbers. But on the heels of these disappointing results, retailers got a beam of hope as February's sales numbers showed a surprising increase.

Encouraging news for retailers showing a rebound in consumer spending during the past month came after world's largest retailer Wal-Mart Stores Inc. (NYSE: WMT) announced a rise of 2.6% for its February same-store sales. The company said that its same-store sales during the period were helped by strong gains from gas, food and flat-panel TVs. Analysts were expecting the retailer show an increase of 1.1% for its same-store sales, according to Thomson Financial.

Among other retailers that showed a rebound in February sales were Costco Wholesale Corp. (NASDAQ: COST) and Saks Inc. (NYSE: SKS), both of which reported stronger-than-expected gains. Apparel retailers Pacific Sunwear of California Inc. (NASDAQ: PSUN) also reported earnings results exceeding estimates of 6% sales growth last month.

For Limited Brands Inc. (NYSE: LTD), though, February didn't come with positive results. The company stated that higher energy and food prices put pressure on consumers who focused on necessities.

The Wall Street Journal's "Numbers Guy" takes a look at the issue of counterfeiting of luxury goods, a major thorn in the side of such couturiers as Coach (NYSE: COH) and Gucci. According to The Numbers Guy, "Washington business groups such as the U.S. Chamber of Commerce and the International Anticounterfeiting Coalition calculate that global counterfeit sales equal $600 billion to $650 billion a year -- numbers parroted in news releases by companies claiming to fight piracy. They build on the often-cited claim that counterfeit goods represent 5% to 7% of all world trade."

The problems with this statistic are twofold: First, it's hard to get accurate data on the operations of organized crime. Secondly, even if we do know how many knock-offs are being sold, it's hard to say how much of that is actually detracting from the sales of the high-fashion labels: Is someone who buys a $10 pair of "Gucci" sunglasses from a street vendor really buying those instead of $300 Gucci sunglasses? Or is that sale instead coming at the expense of less expensive retailers like PacSun (NASDAQ: PSUN) or even Wal-Mart (NYSE: WMT)?

It's unclear how much illegal knock-offs are really hurting designers, but there's another issue that definitely is hurting them and, for now at least, it's legal: lower-budget knock-offs, perfectly legal because there's no logo, of runway couture, often before it even hits stores.

In September, I wrote that one of these knocker-offers saw herself as a champion of womens' rights -- "to look fabulous." But some of the fashion houses are lobbying Congress to pass bills granting greater copyright protection for designers.

Check out this excellent Los Angeles Times piece for the pros and cons of that.
