FRANKFURT (dpa-AFX) - Aurubis shares slipped below the 50-day line on Tuesday after investment plans were announced, falling 5.3 percent to 71.94 euros.

Europe's largest copper producer is investing a further 330 million euros in its Hamburg site. This includes the construction of a new plant for processing precious metals with an investment volume of 300 million euros, as the MDax group announced. At its most recent meeting, the Supervisory Board also approved a 30 million euro investment in a plant to reduce fugitive emissions in copper production. Together with previously approved projects, Aurubis is currently investing more than 750 million in its plant at its Hamburg headquarters.

Experts from Morgan Stanley criticized that the new investment plans were accompanied by rather limited predictability with regard to the future profit contribution. The company had not announced a target for the profit contribution of the projects.

With the price slide on Tuesday, the shares fell to their lowest level since October. They had recovered to 82.50 euros by mid-November, but have recently come under pressure again./mis/stk
