Asia stocks mostly lower after China GDP; profit-taking hits Nikkei

Asian share markets were mostly lower on Tuesday following a mixed morning session as investors digested key data from China.

China's gross domestic product (GDP) grew 7.3 percent on year in the July-September period, the slowest pace in nearly six years. Still, the figure was above forecasts for a 7.2 percent rise. Other data showed September industrial output increasing 8 percent on year, beating estimates, but retail sales and fixed-asset investment both missed expectations.

"While disappointing data may spark another round of growth concerns and trigger risk aversion, it may also raise bets that more targeted measures will be implemented to reach the official growth target of 7.5 percent," said Vishnu Varathan, senior economist at Mizuho Bank in a note.
