Filipino traders continue activities despite a short power glitch at the Philippine Stock Exchange in the financial district of Makati, south of Manila, Philippines, on Tuesday Jan. 22, 2008. Philippine shares tumbled to a five-month low, as Asian markets took a beating amid concerns over the U.S. economic outlook. The Philippine Stock Exchange Index closed down 173.89 points, or 5.5 percent, at 2.978.41, its sharpest fall since the subprime-induced retreat in August.
