Hong Kong stocks eked out marginal gains on Wednesday, drawing inspiration from a mainland rally, but gains were limited as investors were cautious before a highly-anticipated meeting between US President Donald Trump and his Chinese counterpart Xi Jinping later this week. The benchmark Hang Seng index added 0.6 percent, to 24,400.80 points, while the Hong Kong China Enterprises Index gained 0.5 percent, to 10,365.32 points. Much of the market's attention was on the landmark Trump-Xi summit on Thursday and Friday. Most sectors gained ground at the close, with services and tech stocks leading the gains.
