FRANKFURT (dpa-AFX Broker) - Krones ' gains of the previous day are already history again on Friday. Burdened by a downgrade, the shares of the manufacturer of beverage bottling plants recently lost 4.3 percent.

The cautious assessment of Krones with regard to further margin increases this year could be a stumbling block at the current share price level, wrote analyst Jorge Gonzalez Sadornil of Hauck Aufhäuser Investment Banking. The expert removed his buy recommendation. The shares had gained almost a third during their rally from the beginning of November to the previous day./ajx/stk
