Adidas' share value jumped by more than 10 percent to 92.37 euros ($100.63) just after midday on the Frankfurt stock exchange as traders welcomed the news that Kaspar Rorsted would be taking over Herbert Hainer's duties in October.
"It's very positive. (Rorsted) is someone who did a very good job at the helm of Henkel," Cedric Rossi, a stock analyst at Bryan Garnier, told the AFP news agency.
But while Adidas's shares were the biggest winner on Germany's blue-chip DAX 30 index on Monday, Henkel's shares were the biggest loser. Its stock fell 4.5 percent to 89.32 euros.
Henkel is behind consumer goods such as Persil laundry detergent and Schwarzkopf shampoo. The company's supervisory board signed off on Rorsted leaving before his contract was formally due to expire in 2017, saying that he would be gone by April 30 and be replaced by board member Hans Van Bylen.
Adidas said Rorsted would begin as an ordinary member of the company's executive board - an entity that operates separately from a company's supervisory board under German corporate law - effective August 1. After a two-month transitional period, he will take over as CEO.
