FRANKFURT (dpa-AFX) - Speculation about the entry of an activist investor drove the shares of Delivery Hero on Thursday. The shares of the online food delivery company jumped by up to 9.4 percent to their highest level since December last year. Most recently, they were still up 7.5 percent at around 31 euros. This made the shares the best value in the MDax. The index of medium-sized stocks rose slightly.

The investor Sachem Head Capital Management had built up a 3.6 percent stake in Delivery Hero and was able to seek a seat on the supervisory board of the German food delivery company, the news agency Bloomberg reported, citing people familiar with the matter. Sachem Head Capital Management could also seek to replace the CEO of the online food delivery company, Niklas Oestberg.

According to the investor, Delivery Hero's operating performance and share price are disappointing compared to its competitors, it added. Sachem Head Capital Management did not wish to comment on this. Delivery Hero said it does not comment on rumors./la/he
