Puma's listing on the Frankfurt stock exchange has moved from the MDax index to the SDax index for smaller German firms. The demotion has been explained by a 7 percent drop in the company's stock market capitalization in the last 12 months and the fact that less than 20 percent of Puma's shares are publicly traded. On the other hand, the Metro Group has gone back up to the Dax index from the MDax.
