Wal-Mart (WMT 50.66) CEO Lee Scott is stepping down and will be replaced by Mike Duke, effective February 1, 2009.
Duke previously led Wal-Mart's Logistics Division, U.S. operations and International operations. He was elected to the company's board of directors, effective immediately.
Scott's retirement comes after nearly 30 years with Wal-Mart, with the last nine as president and CEO.

WMT is up 1.7% in pre-market trading.
