Goldman Sachs has lowered earnings growth forecasts for China’s companies and Credit Suisse cut stock index targets as the economy slows.

Profits for companies in the MSCI China Index might increase 1.8 per cent this year and 8.6 per cent in 2013, compared with previous estimates of 6 per cent and 12.3 per cent, Goldman Sachs analysts Helen Zhu and Timothy Moe wrote in a report this week.

Credit Suisse lowered its 12-month target for the index to 60 from 70, analysts Vincent Chan and Peggy Chan said in a report.
