Hong Kong stocks sank on Tuesday after Societe Generale SA cut its China growth forecast and Goldman Sachs Group reduced its earnings estimates for Chinese companies. However, hopes that weak China's data will result in more accommodative monetary policy restricted losses of Chinese equities. The Hang Seng Index lost 0.66% to end Tuesday's session at 19,429.91. Only one in nine sectors included in the index advanced. Consumer services industry was the only gainer, with Sands China climbing 1.43%. At the same time, consumer goods and technology companies created heavy pressure on China's blue chips index. China Resources Enterprise and Li & Fung dropped by 1.49% and 2.93% while Tecent Holdings plunged by 1.41%. Banking sector was also bearish after Credit Suisse cut the sector to ‘marketweight' from ‘overweight'. Bank of China and Bank of Communications plunged 1.06% and 0.79% .
