Bitcoin over $50,000 after price jump, Dax in the red on the stock market. Investors are heading into Tuesday cautiously; the DAX is hardly moving.

The focus is on the shares of Rheinmetall and Tui – and the cryptocurrency Bitcoin. On the economic side, the German ZEW economic barometer will be published in the morning, before the even more attention-grabbing US consumer prices come into focus in the afternoon. Tuesday's inflation data release promises to be the most important event of the week, said Chris Beauchamp, chief market analyst at IG.
