Initially, good specifications from the Asian stock exchanges and fresh economic data from Germany provided positive impetus.
The Dax was quoted in the afternoon 0.07 percent higher at 15,555.70 points.
On Friday, the leading German index had lost around 0.6 percent and on a weekly basis around 0.8 percent.

Vonovia wants to acquire at least half of the shares again, but failed at this threshold in the most recent attempt.
