FRANKFURT (dpa-AFX Broker) - Thyssenkrupp shares on Monday significantly extended their recent losses, reacting negatively to the surprise upcoming change at the top of the company. The shares slumped 8.3 percent to 6.696 euros, making them by far the weakest stock in the MDax. The mid-cap index rose by 0.6 percent.

CEO Martina Merz wants to leave her post as head of the steel and industrial group ahead of schedule. The Supervisory Board's Personnel Committee intends to comply with her request and hold talks with her. In addition, the Personnel Committee already has a successor in mind: Miguel Ángel López Borrego, the current interim head of the automotive supplier Norma Group, is to be proposed to the Supervisory Board as the new CEO effective June 1. Norma's shares hardly reacted at all and recently gained 0.6 percent./la/mis
