HONG KONG (AFP) - A soft lead from Wall Street and cautious profit taking prompted mixed trade in Asian shares Tuesday, as a stronger yen weighed on exporters in Tokyo and share glut fears stalked Shanghai. A note of concern returned to the markets as traders watched for signs of progress on debt-strapped Greece, with meetings this week between European Union representatives and Greek authorities to discuss the countrys finances. Investors were also happy to remain on the sidelines ahead of US Federal Reserve chairman Ben Bernankes congressional testimony on the economy and monetary policy due Wednesday and Thursday. Key US economic data including housing, consumer confidence, and fourth-quarter gross domestic product are also due this week. The downward correction has probably run its course but the markets are more likely to trade sideways for a while, IG Markets strategist Ben Potter told Dow Jones Newswires. Tokyo closed down 0.47 percent, or 48.37 points to 10,352.10 as traders took profits from Mondays strong gains as a stronger yen chipped at exporter share prices.

Shanghai closed down 0.69 percent, or 20.82 points at 2,982.58, led by financial, energy, steel and metal firms amid lingering tightening concerns and worries over an impending increase in share supply. Investors are wary of the tightened credit environment, said Zhao Jianxing, an analyst from China Merchants Securities. Ping An Insurance tumbled 8.9 percent after the insurer said three of its shareholders would be free to sell 39 billion yuan in shares from Monday when a three-year lock up expires. However, Hong Kong recovered from earlier losses to close up 1.21 percent, or 245.73 points, at 20,623.00. Banking giant HSBC rose 2.0 percent to 85.30 Hong Kong dollars, boosted by increased demand ahead of the companys 2009 results due Monday. Seoul ended up 0.11 percent, or 1.8 points at 1,628.90.

Wall Street provided a soft lead, with US shares losing 0.18 percent overnight after a week of solid gains. Traders were waiting for comments this week from Fed chairman Bernanke on the state of the economy to panels of the House of Representatives and Senate. He is expected to shed light on the central banks sudden decision last week to hike interest charged on short-term emergency loans given to banks. The hike triggered fears of a drying up of credit despite a fragile economic recovery and was taken as a sign that the US had started to unwind massive stimulus measures to support the economy during the financial crisis.
