A German shareholder lobby group on Tuesday urged Berlin to improve regulation of capital markets amid rising investor irritation about “creeping takeovers” such as Schaeffler’s hostile move on Continental, the car parts and tyre maker.

The action took place as Conti and Schaeffler resumed talks on Tuesday, but there was no news of progress. Klaus Schneider, head of SdK, which represents shareholders’ interests, said Schaeffler’s approach on Conti could have disadvantaged those who sold their shares early: “It is time for the German government to think about this issue.”
