Validea is an intriguing newsletter that selects stocks based on the strategies of the market's most legendary investors. Here, editor John Reese takes a look at Aeropostale (NYSE: ARO).

"This mall-based clothing retailer targets youngsters age 14 to age 17 through more than 900 stores in 49 states, Puerto Rico, and Canada.

"The company has developed a new retail store concept called P.S. from Aeropostale, which will offer casual clothing and accessories focusing on elementary school children between the ages of seven and 12.

September same-store sales are rolling in this Thursday morning, and the news for the teen/tween retailers may hold some hope. Leading off the clothing genre is American Eagle Outfitters (NYSE: AEO), which posted perhaps the best news in the group. Of course, by best news I mean that AEO's sales didn't drop as much as people predicted.

The retailer had flat same-store sales in September, at the top end of its forecast range for a drop of 4.1% to flat sales. Thing is, these results will probably spur a bit of a rally for the stock, mainly because they weren't as bad as they could have been.

All three of the major indexes finished Tuesday in the red, but there were several big names that moved up to new 52-week highs in Tuesday's trading.

Walgreen Co. (NYSE: WAG): The drugstore giant had a really good day on Wall Street after posting better than expected earnings in the morning before the market opened. The company posted earnings of 44 cents per share versus analyst estimates of 39 cents. The stock set a new 52-week high of $38.44 and closed the day up 9.2% at $37.35.

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

• American Eagle Outfitters Inc. (NYSE: AEO) Q2 profit fell short of estimates as same-store sales declined.
• Ann Taylor Stores Corp. (NYSE: ANN) Q2 earnings beat very low expectations and same-store sales fell.
• Big Lots Inc. (NYSE: BIG) reported better-than-expected numbers for Q2, sending shares upward.
• Burger King Holdings Inc. (NYSE: BKC) posted a better-than-expected Q4 profit though revenue declined.
• China Petroleum & Chemical Corp. posted a record Q2 profit after restrictions on fuel prices were lifted.
• Dell Inc. (NASDAQ: DELL) said its Q2 earnings declined, but they still topped analysts' expectations.

American Eagle Outfitters (NYSE: AEO), a fashion retailer that competes with Gap (NYSE: GPS) and Abercrombie & Fitch (NYSE: ANF), didn't do too well in Q2. Total sales went down 5%, and earnings per share on a GAAP basis fell a most awful 50% to 14 cents. According to Bloomberg, the adjusted earnings of 12 cents per share came up short of analyst expectations by three pennies.

Same-store sales hit the double-digit mark to the downside: they decreased 10%. Not a good number for this kind of business. Promotional markdowns helped to drive the gross margin down. The operating margin also took a hit.

Canadian banks are scheduled to step into the earnings spotlight this week, with third-quarter reports coming from Bank of Montreal (NYSE: BMO), Bank of Nova Scotia (NYSE: BNS), Canadian Imperial Bank of Commerce (NYSE: CM), Royal Bank of Canada (NYSE: RY), and Toronto-Dominion Bank (NYSE: TD). While Canadian banks on the whole held up better than their U.S. counterparts during the financial crisis, these five are expected to report that their earnings are still declining in the most recent quarter.

Analysts surveyed by Thomson Reuters are looking for EPS for these banks to have fallen from 15% to 25% from a year ago. Their long-term EPS growth forecast is for between 10% and 12%, which is in the same range as U.S. rivals JPMorgan Chase & Co. (NYSE: JPM) and Wells Fargo & Co. (NYSE: WFC), but better than Bank of America Corp. (NYSE: BAC) and Citigroup Inc. (NYSE: C). Earnings multiples for these Canadian banks are 10x to 12x, but none of them have a First Call consensus recommendation is to buy. The Motley Fool, though, considers TD as a value stock and RY a stock poised to pop. All of them are trading much closer to their 52-week highs than lows, and shares of all are up more than 100% since March lows.

Aeropostale (NYSE: ARO), a retailer that competes with Abercrombie & Fitch (NYSE: ANF), American Eagle Outfitters (NYSE: AEO), and Gap (NYSE: GPS), posted what I thought was a superb second-quarter earnings summary on Thursday after the bell. The figures were very appealing, and I would've expected a better after-hours reaction by the stock to the news. Then again, the market can never be predicted. It will do whatever the heck it wants.

Net sales increased 20%. Not bad, am I right? Wait, check this out. Earnings per share came in at 57 cents, compared to the 31 cents reported in the year-ago quarter. According to Reuters, that was a penny ahead of expectations. But that penny beat on the bottom line isn't what impresses me the most. It's the strong per-share profit expansion that I find compelling.

Abercrombie & Fitch (NYSE: ANF) is such a funny stock story. The company reports what I thought was a quarter full of dire results, and the market still sends shares higher. They closed almost 4% higher, in fact, on Friday. I don't get it.

For the second quarter, sales decreased 23%, and the overall same-store sales statistic, which is a really important metric for retailers, sank 30%. A net loss of 30 cents per share was booked, mostly on the back of the discontinuation of the Ruehl business. Excluding the effect of the closure, Abercrombie made 8 cents per share, and that, according to Reuters, beat by a mile the expected loss of 7 cents per share.

American Eagle Outfitters (NYSE: AEO - option chain) shares are rising today after the company updated its Q2 EPS forecast to 16 cents, including a 2-cent tax benefit. AEO had previously forecast EPS of 12 to 15 cents, while analysts are expecting EPS of 14 cents. AEO also announced July same store sales that declined more than expected, but that news was offset for traders by the revised forecast. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on AEO.

AEO opened this morning at $14.50. So far today the stock has hit a low of $14.40 and a high of $14.95. As of 11:30, AEO is trading at $14.70 up 74 cents (5.3%). The chart for AEO looks neutral and S&P gives AEO a neutral 3 STARS (out of 5) hold ranking.

Last summer we lamented the price of gas. This year, however, there's at least one upside. Retail sales for June were up 0.6% - substantially better than the 0.4% anticipated – with the gas prices leading the charge. A slight tip in the brutalized auto manufacturer sector helped, as well. This was the largest retail sales increase in five months.

Gas stations benefited from the cost of fuel, adding a bit of pep to a beleaguered retail industry: sales were up 5% year over year, after doing the same in May. And, car dealers had their best month since January: the sales of cars and parts climbed 2.3%. Nonetheless, this corner of the retail world is still off 14.5% from last year. It may have helped last month, but we're still pretty far from a cure.

The second quarter is now behind us and for the most part it was a positive one in terms of the market pushing higher almost 40%. This is the second review of my 2009 stock picks through June 30 (see: Chasing Value: 9 picks for 2009 -- APC, GE, ISRG, WFC and more). There was a lot of talk about green shoots this past quarter as Wall Street was looking for any small bit of optimistic data to support the market.

The federal printing presses continued to run at full speed pushing the dollar lower and oil prices higher. While the feds were printing money to cover their deficits, the States do not have that same luxury and many of them are having trouble balancing their budgets to the tune of billions of dollars.
