(Management shakeups article updated with latest shakeup in GM, Dynegy and American Eagle Outfitters)NEW YORK ( TheStreet) -- Barely three months into 2011, and the Street has already seen several prominent management shake-ups that could change the course of some of the biggest companies, including Google ( GOOG - Get Report), AMD ( AMD - Get Report) and Citigroup ( C - Get Report) and General Motors ( GM - Get Report). Could this be a sign of things to come? "We could see more changes like this as the economy continues to pull out of recession," noted John A. Challenger, chief executive officer of the global outplacement firm Challenger, Gray & Christmas in the January report on CEO departures. "Despite evidence that stability at the top is a key element to long-term success, many companies feel that certain CEOs are better suited for holding the ship steady through rough waters, while others are better for expansion," he said. According to Challenger's data, 2009 and 2010 saw fewer CEO exits, possibly reflecting an unwillingness to rock the boat at the height of the recession. Through the first two months of the year, a total of 188 CEO departures have been announced, which is down 15 percent from 2010 when 221 chief executives left their posts in January and February. Tech companies led the shakeups in January, while the financial, non-profit and healthcare sectors saw the biggest turnover in February. The top reason for CEO departures so far this year has been resignations. Shareholders often worry about the impact on the company as it transitions under a new management. They tend to favor companies that have a clear succession plan in place and see sudden changes as a sign of trouble. In the cases of struggling companies however, a change in management is usually seen as a welcome opportunity to overhaul strategy. Read on to find out which of your companies are seeing big changes in their executive ranks.
