After the recent slide in prices, some investors are venturing back into the German stock market.

At the opening on Tuesday, the Dax rose by 0.1 percent to 13,959 points.

"At the moment there are not many who dare," said portfolio manager Thomas Altmann from the investment advisor QC Partners.

"But some courageous people are currently taking action." The balance sheet season, which has been quite positive overall so far, is helping.

However, it is unclear whether the companies could keep their profits in the coming quarters in view of material bottlenecks, delivery problems and high energy prices.

In addition, many investors held back in anticipation of the interest rate decision by the US Federal Reserve on Wednesday.

The leader in the Dax was Deutsche Post with a price increase of 3.6 percent.

The mail and parcel delivery company increased sales and profits at the start of the year.

The numbers are significantly better than expected, praised a broker.

Covestro, on the other hand, collapsed by seven percent after the plastics manufacturer cut its full-year targets due to rising costs and the corona lockdown in China.

The extent of the forecast reduction highlights the uncertainties in the global chemical market, commented analyst Chris Counihan from the investment bank Jefferies.

Covestro apparently owes the surprisingly strong result at the beginning of the year to the fact that customers had stocked up in anticipation of future price increases.
