SINGAPORE (AFX-ASIA) - The dollar was slightly weaker against the yen in quiet trade on profit-taking after the dollar's gains on Friday following stronger-than-expected U.S. GDP data in the first quarter, dealers said. "The stronger-than-expected U.S. GDP data is more or less discounted now," a dealer with a European bank said. "More and more people are becoming convinced that the U.S. economic recovery will be a V-shaped one," he said. Trading in Asia is quiet, he said, with Tokyo shut for a public holiday. Tokyo is also closed on Thursday and Friday. Trading in Europe later today is expected to be more active, with most corporates there likely to bolster their long positions on the U.S. dollar, the dealer said.
