Greg Whalley: In the Line of Fire

Greg Whalley knows a thing or two about getting ready for battle. During the 1980s, the West Point graduate served with the U.S. Army. That experience could come in handy in his new job as president and chief operating officer of Houston energy trader Enron.

Since the beginning of the year, Enron (ENE) shares have plunged 50% in the wake of dropping energy prices. The stock has also been hit by fallout from other issues, including the company's ailing broadband venture and the abrupt, Aug. 14 resignation of President and CEO Jeffrey Skilling.
