June 23 (Reuters) - Hong Kong shares rose for their fifth straight day on Thursday, reflecting growing optimism that Britain will vote to stay in the European Union.
The Hang Seng index rose 0.4 percent, to 20,868.34, while the China Enterprises Index gained 0.3 percent, to 8,785.07 points.
But trading remains thin as investors took to the sidelines awaiting Thursday's referendum. Results will begin emerging early on Friday morning in Asia, with most expected between 0100 and 0300 GMT.
