Goldman Sachs has made several changes to its Conviction Buy List this morning. Most notably was a removal of Wal-Mart Stores Inc. (NYSE:WMT) from the list. Goldman replaced Wal-Mart's place with Target Corp. (NYSE:TGT).

TGT was given a $68 target and WMT target was cut to $53 from $57 per share. On Wal-Mart, Goldman analysts believe a turnaround is in its early stages and they see little positive momentum into the critical holiday season. Goldman Sachs maintained an official Buy rating for WMT, but simultaneously lowered Fiscal 2006 EPS from $2.87 to $2.83. Target (TGT) EPS estimates were raised by $0.01 to $3.18.

Baxter International Inc. (NYSE:BAX) & Aracruz Celulose (NYSE:ARA) were also trimmed off the Americas Conviction Buy List as was Flextronics International Ltd. (NASDAQ:FLEX). FLEX shares are down 9% since being added to the list in September and Goldman expects a more of a seasonal slowdown. On the other hand, Crown Holdings (NYSE:CCK) was added to Goldman Sachs Americas Conviction Buy List.
