The Dax lost momentum again on Tuesday. Shortly after the start of trading, the leading German index was down 0.03 percent at 15,890 points, after having gained around half a percent at the beginning of the week.

The Dax is thus stuck in the range of the past few trading days between around 15,700 and a good 16,000 points. Concerns about the global economy, but especially that in China, had slowed the stock markets recently.

There was bad news from China again this morning: Both retail sales and industrial production fell short of expectations in July. In order to support the weakening economy, the Chinese central bank is turning the interest rate screw again. The interest rate for loans with a one-year term has been lowered.

The MDax for medium-sized companies rose by 0.26 percent to 28,089 points. The Eurozone leading index EuroStoxx 50 gained 0.13 percent.
