May 20 - Hong Kong shares followed most other Asian stock markets higher on Friday, but light volumes indicated caution as investors braced for a U.S. interest rate hike possibly as early as next month.

All main sectors rose, with IT and energy shares leading the rise. (Reporting by Samuel Shen and Pete Sweeney; Editing by Kim Coghill)
