HONG KONG, July 25 (Reuters) - Hong Kong shares dropped 1.5 percent on Friday, as analysts predicted the end of a short-lived global rally after disappointing U.S. home sales data rekindled worries over the health of financial markets.

But the main index rose 4 percent over the week, posting its best weekly gain in three months, rallying in line with a rebound in global financial stocks.

Energy stocks took a beating on a raft of news including more rigid price controls, profit warnings and easing oil prices.

China Shenhua Energy (1088.HK: Quote, Profile, Research, Stock Buzz) fell 6.7 percent, adding to Thursday's 4.9 percent fall, after Beijing announced stricter price controls on thermal coal used by power plants.
