Asian shares slipped from near three-week highs hit earlier this month on Friday, as a rally in oil prices paused and investors remained cautious about the outlook of the global economy. MSCI’s broadest index of Asia-Pacific shares outside Japan fell 0.2 percent while Japan’s Nikkei (.N225) dropped 1.5 percent. MSCI’s emerging market index (.MSCIEF) hit a six-week overnight on signs of stabilization in oil prices, but U.S. shares dipped, with S&P 500 (.SPX) shedding 0.5 percent, dragged down by lackluster earnings from Wal-Mart Stores (WMT.N).
