FRANKFURT (dpa-AFX) - Shares in Germany's largest stock market heavyweight, SAP, slipped into negative territory around midday on Thursday. Investigations announced by the EU Commission caused a previously minor discount to turn into a loss of up to 2.6 percent. The downward trend that began in the summer continued, even though the decline recently moderated somewhat to 1.3 percent.

The EU Commission has launched an investigation into possible anti-competitive practices. The software manufacturer is suspected of distorting competition in maintenance and support services, according to the Brussels authorities. This brought an end to a recent tentative attempt to stabilize the shares.

In 2025, SAP remains among the DAX losers with a discount of almost five percent. Since mid-July alone, it has lost 16.5 percent of its value, relinquishing its position as the most valuable listed company in Europe to chip industry equipment supplier ASML.
