Advanced Micro Devices (AMD) on Monday rose in New York trading on speculation that the departure of top executives has made it an acquisition target by Dell.

Ian King with Bloomberg on Monday quoted analyst Patrick Wang with Wedbush Securities, who sais "there is no management team there," at AMD, and that "there is some 'chatter' that the company is up for sale," but that in his view, "it's a far-fetched possibility."

Last week, AMD said Chief Operating Officer Robert Rivet and strategy head Marty Seyer are leaving the company. Their departures follow the exit of Chief Executive Officer Dirk Meyer, who resigned Jan. 10 after a dispute with the board over progress in winning back server market share and a lack of offerings for the mobile computer market.
