(new: aspect share buyback program, further analyst opinion, share price development)

FRANKFURT (dpa-AFX) - The shares of Commerzbank continued to be weak Friday afternoon. However, they curbed their high price minus of five and a half percent from early trading to just two percent. They thus cost 10.75 euros. At the same time, the Dax was half a percent lower. Compared to the turn of the year, Commerzbank shares are currently trading more than a fifth higher.

The bank's quarterly figures were generally well received. Market participants cited statements about the next share buyback as reasons for the price slide. The announcement that share buybacks are only part of the existing payout ratio is causing frustration among investors, wrote analyst Timo Dums of DZ Bank.

One trader also urged caution with regard to the cost situation. The prospect of rising costs could become a problem for the share price, he said before the Xetra start. For example, Commerzbank's top management now expects higher costs this year than recently.

Higher interest rates meant that Commerzbank had to absorb a new burden from the Swiss franc loans in Poland in the second quarter. Further provisions for Poland loans are possible, however, according to the institute.

The new forecast for interest income initially met with a positive response, but was quickly put into perspective somewhat. It is currently above the market consensus, but the implied slowdown in the second half of the year will raise questions, wrote analyst Benjamin Goy of Deutsche Bank Research in an initial assessment./ajx/stw
