Hong Kong stocks failed to hold on to early small gains as earnings worries clouded the horizon. The Hang Seng index dipped 11.38 points to 10,713.92 as leading local bank shares were sold on fears that chronic economic problems will pull down earnings this year. Bank of East Asia, the largest local bank, which is due to report next week, fell almost 2%, but HSBC Holdings was targeted by bargain-hunters and added 25 cents to HK$88.25. Major conglomerate Hutchison Whampoa fell 1.7% after warning of heavy losses on its Italian 3G mobile phone venture.
