For those of you who took advantage of Staples Inc. (SPLS) $17 bottom, discussed in September, to scoop-up more shares, you made the correct move.

Office supplies chain giant Staples Inc., first discussed here on April 21, 2008, at a price of $22.11, has moved smartly higher, and I still like the shares at this stage.

Staples will likely post FY2012 sales growth of 4% to 6%, after a 2% to 3% increase in FY2011.

I first discussed Staples Inc. (SPLS) here on April 21, 2008, at a price of $22.11. The question now is, has the office supplies chain giant put in a bottom near $17? The calculation here is that it has.

Look for Staples to post FY2011 sales growth of 2% to 4%, after a 5.2% increase in FY2010.

Staples should open about 40 net new stores this fiscal year, to total about 2,500, with both U.S., and international zones gaining stores. About 1,000 of Staples stores are located outside the U.S., with Canada (316) and Europe (about 190) hosting the bulk.

If you're looking to hit the "easy button" and make some money in the stock market, you might want to look at Staples (SPLS).

Goldman Sachs -- citing the firm's growing market share and moves to buy back stock -- recently placed Staples on its Conviction Buy List and raised its price target from $22 to $23.

Of course, the stock is going to have to break out of the downtrend it has been in for the past few months before this looks like an attractive technical trade, but the fundamentals are starting to line up.

Analyst Upgrades

• JPMorgan upgraded Anadarko Petroleum (APC) to overweight from neutral on valuation as it views the recent pullback in shares as excessive. Despite upgrading, the firm lowered its target for shares to $82 from $90.
• Oppenheimer upgraded Office Depot (ODP) to perform from underperform and upped its target for shares to $7 from $3 after raising its estimates for companies in the Office Products Retail space. The firm expects trends to accelerate for the sector due to moderating unemployment pressures. In conjunction with the upgrade, Opco raised its target for OfficeMax (OMX) to $26 from $21 and target for Staples (SPLS) to $30 from $28. Both stocks remain outperform rated.

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.
