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.

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.
