The market hit a high for 2011 today after the unemployment rate fell to 8.8% and after the economy created about 216,000 jobs. The Institute of Supply Management showed a slight drop for March, but investors were positive most of the day. Selling in the last 90 minutes of the day felt a bit surprising -- but that may be nothing more than pre-weekend profit taking.

Here were today's unofficial closing bell levels:

Dow Jones: 12,376.72 +56.99 (0.46%)

Nasdaq: 2,789.60 +8.53 (0.31%)

S&P500: 1,332.41 +6.58 (0.50%)

U.S. stock futures are lower this morning as unrest continues in the major oil-producing state of Libya.

U.S. stocks closed higher on Friday, with the Dow Jones Industrial Average gaining 0.59% the Nasdaq 100 index rising 0.08% and S&P 500 index gaining 0.19%. U.S. markets were closed on Monday for the Presidents' Day holiday.

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.

When a stock rallies 7% after the company announces the CEO is resigning, it's easy to tell he wasn't doing a good job. This is part of the case for Office Depot (ODP) this morning. The retailer announced Steve Odland, Chairman and CEO of ODP since 2005, will resign effective November 1. Neil Austrian will become the interim chairman and CEO while ODP looks for a permanent replacement.

"We thank Steve for his contributions to our Company, beginning in 2005, and through one of the toughest economic climates in memory. During his tenure, the Company grew and achieved record revenues and profits, and we have seen some improvement in margins coming out of the depths of the recession," the company said in a statement.

Option investors are pushing call option prices higher in the Independent Oil & Gas industry and are pushing put option prices higher in the Medical Instruments & Supplies industry today.

Any time the volatility skews above 1.00, it is an indication that calls are more expensive than puts. Typically, when calls are more expensive than puts, it means the demand for calls is greater than the demand for puts because investors believe the stock is going to rise in the future and they want to take advantage of that movement by buying calls.

The opposite is also true. Any time a volatility skews below 1.00, it is an indication that puts are more expensive than calls.

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

• Coinstar Inc. (CSTR) shares surged following stronger-than-expected Q1 earnings driven by DVD rentals.
• Humana Inc. (HUM) shares traded lower despite the report of better-than-expected earnings for Q1.

Office Depot, Inc. (ODP), whose colleagues include OfficeMax Incorporated (OMX) and Staples, Inc. (SPLS), was off by 1.4% at the time of this writing in afternoon trading. That put the share price below the $7 level. The stock is also well below the 52-week high of $9.19. What do the technical and fundamental factors tell us about the potential of this investment idea?

They're not telling us comforting things, in my opinion. The one-year chart doesn't look too bad. Like many other one-year charts, it shows a company that wants to head higher, albeit in a choppy way.

Staples (SPLS) issued Q3 results early this morning, and the market loved them. In afternoon trading, the stock was bid higher by over 6%, with awesome volume backing the trade.

According to the press release, total sales decreased 6%. Earnings per diluted share declined as well, dropping 7% on an adjusted basis to 39 cents. That was good enough, though, to beat expectations by a penny, as indicated by our preview piece.

Staples Inc. (SPLS), whose website had trouble keeping up with the crush of Black Friday traffic, is scheduled to discuss its third quarter 2009 financial results in a conference call Tuesday, December 1, at 8:00 AM ET. You can catch the live webcast of the call on the company's website.

During the three months that ended in October, Staples executives sold shares and the company was named one of the world's 100 hardest working brands. Analysts surveyed by Thomson Reuters expect the world's biggest office supply superstore operator to report that earnings for that period fell 9.5% from a year ago to $0.38 per share. Revenue for the quarter is expected to be 7.3% lower to $6.5 billion.

In his 'Master Trading' portfolio, Bernie Schaeffer uses fundamental, technical and sentiment metrics to select trades. Here's a trio of ideas from Schaeffer's Investment Research.

"I have initiated a long position in Office Depot (NYSE: ODP). Price action for ODP has been strong, with the equity gaining more than 108% year-to-date.

"Recently, the equity pulled back to its 20-day moving average. There is heavy out-of-the-money put open interest for ODP. An unwinding of the short positions related to this open interest could provide a tailwind for the stock.

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.
