China, the region's largest trading partner, grew at its weakest pace in almost three decades in the third quarter, as the bruising trade war with the United States hit factory production.
While bleak data has raised prospects for further policy easing, analysts at OCBC said that a few positive factors, such as a truce in the trade war, a pickup in infrastructure investment and stabilization of the manufacturing sector may prompt China's central bank to adopt a wait and see stance.
In contrast to the disappointing 6% annual growth in GDP, China's industrial output grew a better-than-expected 5.8% in September, faster than the 17-year-low posted in August.
Philippine shares <.PSI> led declines in Southeast Asia, with utilities and financial firms among the biggest drags on Manila's benchmark index which managed to post a second consecutive weekly gain.
BDO Unibank and Manila Electric fell 2.6% and 2.3%, respectively.
Singapore stocks <.STI> slipped 0.4% to a one-week low, hurt by weakness in the consumer and financial sectors. United Overseas Bank and Singapore Airlines lost 0.8% and 1.4%, respectively.
Losses in the consumer and telecom sectors pushed Malaysia's benchmark index <.KLSE> 0.2% lower, with food processor IOI Corporation and mobile communication service provider Digi.Com Bhd shedding 3.4% and 1.1%, respectively.
Thai stocks edged lower. Industrial and financial stocks led declines on the benchmark index, with Kasikornbank Pcl and real estate developer Asset World Pcl Corp down 2.2% and 2.9% each.
Investor focus will now turn to the release of trade data next week. The trade-reliant economy's customs-cleared exports in September are likely to grow 1.2% from a year earlier, a Reuters poll showed, after falling 4% the previous month.
Bucking the regional trend, Indonesia stocks <.JKSE> rose 0.2%, with Bank Central Asia, adding 0.7% and auto manufacturer Astra International gaining 1.1%.
