FRANKFURT (dpa-AFX) - The German stock market is likely to remain under pressure on Friday. The broker IG estimated the leading German index at 17,992 points around two hours before the opening, half a percent lower. The day before, it had already fallen by more than two percent due to economic concerns. As a result, the index now looks technically battered - a weekly close below 18,000 points would underpin the picture./mis/jha/
