FRANKFURT (dpa-AFX) - The announcement on the previous evening regarding Jenoptik's promotion to the MDax gave the technology company's recent rally a significant boost on Thursday. By mid-morning, shares were up nearly six percent at 29.30 euros. At its peak, the stock price came within a few cents of the 30-euro mark, a level last tested in June 2024.

As index provider Stoxx, which is part of Deutsche Börse, reported late Wednesday evening, Jenoptik will be joining the MDax alongside engine manufacturer Deutz and steel group Salzgitter. However, one market participant noted that it was somewhat surprising to see Jenoptik included in this group.

The recent rally in Jenoptik shares made the promotion possible, as at the end of last year, the stock was still trading below 20 euros. Currently, with a nearly 50 percent gain for the year, Jenoptik is the second-best performing SDax stock in 2026, behind semiconductor company Elmos./tih/mis
