(fxcue news) - Asian stocks ended mixed on Monday, with mainland Chinese and Hong Kong markets closing sharply higher on stimulus euphoria while Japanese markets succumbed to selling pressure after Japan's governing party chose Shigeru Ishiba, a critic of the country's longstanding ultralow interest rates, as its leader. China's factory activity shrank for a fifth straight month in September but there was some improvement in the overall economic sentiment, an official survey showed. The non-manufacturing business activity posted steady performance in September and PMIs from the private survey underperformed, reflecting broader weakness in both manufacturing and services. A surging yen steadied today after Ishiba called for a loose monetary policy, saying the country's monetary policy must remain accommodative as a trend. Geopolitical tensions remained on investors' radar after Israeli military carried out an air raid on target in the heart of Lebanon's capital for first time in years.

Oil prices climbed more than 1 percent in response to China's stimulus efforts and developments in the Middle East over the weekend. Chinese stocks rose for the ninth consecutive day and extended one of their most remarkable turnarounds in history after three of China's biggest cities eased curbs on home-buying and the country's central bank announced to lower mortgage rates for existing home loans before October 31. The benchmark Shanghai Composite index surged 8.06 percent to 3,336.50 while Hong Kong's Hang Seng index jumped 2.43 percent to 21,133.68. Japanese markets slumped after Ishiba expressed support for the Bank of Japan's moves to raise interest rates from their near-zero level and also backed other policies, such as possibly raising corporate taxes. The Nikkei average tumbled 4.80 percent to 37,919.55 while the broader Topix index closed 3.47 percent lower at 2,645.94.

Tech heavyweight Samsung Electronics lost 4.2 percent and SK Hynix gave up 5 percent.

U.S. stocks ended mixed on Friday as AI investor favorite Nvidia led a broad selloff for chipmakers, offsetting soft PCE inflation report and data showing strong sentiment among U.S. consumers. Data showed the Fed's preferred measure of inflation slowed to 2.2 percent in August from 2.5 percent in July, compared with economists' expectations of 2.3 percent. Core PCE remained sticky at 2.7 percent, raising concerns the Fed may not go for consecutive rate cuts. The Dow edged up 0.3 percent to a new record closing high, while the tech-heavy Nasdaq Composite and the S&P 500 shed 0.4 percent and 0.1 percent, respectively.
