The German economy has been weakening for months - but the large corporations in this country are once again delighting their investors with enormous profit distributions. Only a few stocks are really suitable for long-term dividend investment.

One industry in particular stands out among the dividend aristocrats. The chemical company BASF pays one of the largest chunks of dividends of all DAX companies. The average dividend yield of the Dax was 4.4 percent at the beginning of this year. According to calculations by DZ Bank, the DAX dividend yield has fallen slightly towards 3.5 percent following the index's recent record highs.
