While GameStop will not be announcing its third quarter earnings until Thursday, November 20th, Wedbush Morgan Securities analyst Michael Pachter predicts that the retailer for beat its own guidance for the fiscal period.

Pachter expects that the company will report results that are “slightly higher” than GameStop’s guidance of diluted earnings per share of $0.36-$0.38. He also expects that company will maintain the fiscal year 2008 guidance it outlined in April. At that time, the retailer expected diluted earnings per share of $2.45-$2.50, representing 36 to 39 percent earnings growth.

Pachter also notes that GameStop’s share prices have fall significantly since April, saying that “investors appear concerned that decelerating growth and a worsening economic environment indicate slowing earnings growth.” Pachter disagrees with this stance, maintaining a BUY rating for the stock—though he is lowering the price target for the stock to $34.
