By Chua Kong Ho Nov. 15 (Bloomberg) -- Asian stocks fell this week, ending a two-week rally, as companies lowered earnings forecasts amid mounting evidence economies are slowing. Commonwealth Bank of Australia fell 20 percent after saying bad loans may double and Australian business confidence fell to a record low. Citizen Holdings Co. dropped 9.7 percent after cutting its profit forecast. Hana Financial Group Inc. tumbled 36 percent after Fitch Ratings cut its outlook on South Korea banks. China's CSI 300 Index posted the biggest weekly gain since April, led by steelmakers, after the government announced a $586 billion stimulus plan. ``Investors had expected corporate earnings and economic data to be bad, but the figures keep getting worse,'' said Seo Jung Ho, who helps oversee $2.2 billion at UBS Hana Asset Management Co. in Seoul. The MSCI Asia Pacific Index fell 4.7 percent to 82.10 this week, snapping a two-week rally. Financial and technology stocks had the biggest falls among the 10 industry groups. Japan's Nikkei 224 Stock Average lost 1.4 percent this week and Australia's S&P/ASX 200 Index dropped 7.5 percent. Most other markets in the region fell. Asia Pacific equities retreated on mounting evidence economies are slowing. China's industrial output missed estimates, while South Korea's exports increased at the slowest pace in 13 months in October. In the U.S., the Treasury scrapped plans to buy mortgage assets to focus on supporting consumer credit. Government Responses Leaders from the Group of 20 nations began a summit in Washington yesterday to coordinate government responses to the worst financial crisis in 80 years. The MSCI index for Asia Pacific has lost more than half its value since the peak in November 2007 in the rout triggered by a widening global credit crisis that originated in the U.S. subprime mortgage market. That left shares on the gauge valued at 10 times trailing earnings after last month falling to as low as 8.2 times. Prior to the current turmoil, it never dropped below 10, according to Bloomberg data dating back to 1995. Commonwealth Bank declined 20 percent to A$32.10 this week.

Complete Spending China plans to complete the spending by 2010 to support growth in its domestic economy as the rest of the world slows, the Beijing-based State Council said on its Web site Nov. 9. The funds are equivalent to almost a fifth of the nation's gross domestic product. ``The plan is what the market would like to see most: Something concrete that will be good for the economy,'' said Zheng Tuo, who manages $790 million at Bank of Communications Schroders Fund Management Co. in Shanghai.
