After the recent setback, Dax investors remain cautious.

The leading German index fell slightly to 17,744 points at the opening on Wednesday. "There is still a lot of uncertainty on the stock markets," said Thomas Altmann, portfolio manager at asset manager QC Partners. "And as long as it remains unclear whether the conflict between Israel and Iran will escalate further, it will stay that way."

Among the individual stocks, Adidas moved to the top of the Dax with a six percent increase in its share price. The sporting goods manufacturer scored with strong profit growth and an increased forecast. The preliminary figures for the first quarter were "far better than expected", said one trader. Borussia Dortmund shareholders also rejoiced. After reaching the semi-finals of the Champions League, BVB shares shot up by up to 10.7 percent. In contrast, investors at Continental made long faces. Following disappointing figures at the start of the year, the automotive supplier's shares fell by around four percent.
