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.

Staples (NASDAQ: SPLS), a seller of office supplies and a competitor of chains such as Office Depot (NYSE: ODP), OfficeMax (NYSE: OMX), and Wal-Mart (NYSE: WMT), reported Q2 earnings on Tuesday. Although they weren't that great, I can't say I felt they were a total disaster, either. I think the quarter was lackluster and indicative of the immense work ahead for management in terms of getting people into their stores and increasing sales per transaction.

According to the press release, total sales increased 9% and adjusted earnings per share declined 24% to 16 cents. That's a steep drop, but they did match analyst expectations. Staples used the increase it saw in free cash flow in a smart way: debt reduction. I approve of that move, to be sure.

As the current advertising campaign from Staples Inc. (NASDAQ: SPLS) makes clear, the nation's largest office supply store operator is hoping for what so many retailers (aside perhaps from those participating in the cash for clunkers program) are hoping for: a boost from back-to-school sales. Unfortunately, any such sales won't affect the second quarter results that Staples is scheduled to report tomorrow morning before the market opens. Those results will include July, though, when retail sales were disappointing all around.

Staples is scheduled to discuss its second quarter 2009 results tomorrow morning in a conference call at 8:00 AM ET. You can catch the live webcast of the call on the company's website.

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.

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

• American Eagle Outfitters Inc. (NYSE: AEO) reported better-than-expected Q1 earnings, lifting shares.
• AutoZone Inc. (NYSE: AZO) posted a better-than-expected Q3 profit said it will continue to buy back shares.
• Bank of Montreal (NYSE: BMO) reported lower Q2 earnings and also announced 1,100 layoffs.
• Big Lots Inc. (NYSE: BIG) higher Q1 earnings topped estimates even though same-store sales fell.
• BioMed Realty Trust Inc. (NYSE: BMR) earnings prospects after the recent capital raise led to a downgrade.

Staples (NASDAQ: SPLS) issued its Q1 report on Wednesday. Call me unimpressed. It beat earnings estimates by a penny, coming in at 22 cents on an adjusted basis. Sure, that's what investors want to see. They want the bottom line to go beyond expectations.

But there isn't a lot of excitement to be had with the Staples story. According to the press release, that 22-cent figure represented a decline of 27% in per-share profit. Furthermore, there's weakness in terms of same-store sales. In the North American market, comps dipped 8%. On the international front, comps went down by 14% in Europe.

After the Memorial Day holiday in the United States, the earnings spotlight turns to Canadian banks: Bank of Montreal (NYSE: BMO), Canadian Imperial Bank of Commerce (NYSE: CM), Royal Bank of Canada (NYSE: RY), and Toronto-Dominion Bank (NYSE: TD) are all scheduled to report their second-quarter results.

While banks north of the border of generally have held up better than their U.S. counterparts, analysts surveyed by Thomson Reuters expect the four listed above to report that earnings declined between 20% and 30% since the same period of last year. All four have P/E ratios around 10, and they are paying dividends. Shares of all four have surged 50% to 83% in the past three months, but are still 26% to 38% lower than a year ago.

"I've always liked Staples (NASDAQ: SPLS); the company has traditionally put up good numbers, and the stock price has been rewarding for investors over the years," says Chuck Carlson, noting, "Staples is the world's largest office products company. With $27 billion in sales, Staples serves customers in 27 countries."

The editor of the blue chip advisory, The DRIP Investor, adds, "The stock has gotten hammered by a variety of issues." Here's his review. It is down 40% from its 52-week high

"Yes, the environment for retailers is lousy. Yes, it's tough to see any near-term improvement. And, yes, debt is evil right now. But the stock is already discounting to a large degree those negatives. The stock's current price level is attractive enough to warrant some nibbling.

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

• Aeropostale Inc. (NYSE: ARO) reported strong Q4 numbers as same-store sales increased.
• American Eagle Outfitters Inc. (NYSE: AEO) same-store sales fell in Q4 but earnings met expectations.
• ArcSight Inc. (NASDAQ: ARST) continued its growth in Q3 and it forecast continued growth.
• Buckle Inc. (NYSE: BKE) posted a better-than-expected Q4 profit and continued same-store sales growth.
• Citigroup Inc. (NYSE: C) CEO said in a memo that it earned a profit in the first two months of this quarter.
• Dick's Sporting Goods Inc. (NYSE: DKS) beat Q4 earnings estimates but same-store sales fell.

Staples (NASDAQ: SPLS), whose colleagues include Office Depot (NYSE: ODP) and OfficeMax (NYSE: OMX), is set to report earnings for the fourth quarter on Wednesday, March 11. The famous seller of office supplies has seen its stock go from a 52-week high of $26.57 all the way down to a 52-week low of $13.57.

Actually, that's one of the better ranges I've seen! Goes to show how bad things are out there. Staples saw its shares close at $14.63 on Monday, so a beat on the bottom line could really help things out.

Will management be able to beat? I don't have much confidence that it will, but that doesn't necessarily have to do with Staples per se, it's just that the economy's got me down on so many of these earnings prospects. Analysts are hoping for Staples to do about 42 cents per share in Q4, which would represent a 10% drop in the bottom line.

Concerning the current debate over executive bonuses, value investor Charles Mizrahi contents, "As a shareholder, I have the choice of becoming partners with more than 7,000 businesses on the American stock exchanges."

In his Hidden Values Alert he states, "I've found two companies with managers who are aligned with shareholders. Their compensation packages put them in the same boat as shareholders, and as an owner that is exactly where you want them to be."

Poor Office Depot (NYSE: ODP). Have you checked the price of the retailer's stock lately? It closed on Wednesday with a value of $2.10. It actually rose over 11% that day upon news of its third-quarter earnings. I can assure you that I wasn't buying the stock.

The numbers didn't tell the story of a company that would make a worthy addition to a stock portfolio hell bent on hanging tough during a market meltdown. Instead, the 7% revenue decrease and the loss per share, on an adjusted basis, of $0.01 relate a tale of a business that one should ignore. At least that's the way I see things. Comps in the North American retail division were horrible. The return on invested capital as calculated by management took a significant drop. Let's face it, Office Depot just isn't cutting it. Granted, the economy is wreaking havoc on the business, but come to think of it, I don't really have a good picture of what the brand is supposed to be about. Well, I know it's about office supplies, but why should I shop there as opposed to Staples (NASDAQ: SPLS) or OfficeMax (NYSE: OMX)? Good question, huh? Looks like the retailer needs to get the message out as to why the shopping experience at its locations is of a higher value compared to the office stores mentioned. For that matter, I'm sure a lot of people use Wal-Mart (NYSE: WMT) to pick up office supplies too. My point is that management needs to step up its game and create some better marketing programs for its stores. Be creative like Staples. That "easy button" device is turning into a cool cultural icon (well, I might be exaggerating, but I think it's creative, at any rate).

Earlier, I said "at least that's the way I see things" in terms of my opinion about the sad state of Office Depot, but I suppose I should point out that there are obviously a lot of investors out there who don't see a lot to love when it comes to this chain. The stock is down over 63% on the one-month period at the time of this writing. I see no reason to speculate on this business. The economy isn't getting better, and Office Depot just doesn't seem to be in a strong position. What will it take to turn things around? Like I say, in addition to hoping for an improved macro climate, come up with a better advertising campaign, build a more intense connection with the consumer. Office supplies are commodities, but shopping experience is not. That's the opportunity. Differentiating a brand from the competition based on things like customer service and an easy time of it at the checkout register is a traditional strategy in the retail industry. If Office Depot can offer something in that area, it should let me know about it. Since just about every retailer is struggling to keep the traffic coming into their chains, now is the time to exploit the other guy's weakened state and grab every customer possible.

Disclosure: I don't own any company mentioned; positions can change at any time.
