Asian markets have traded lower on worries over corporate earnings, after some of the major US and Asian companies reported weaker than expected results.

Japan's Nikkei sverage eased 0.14 percent or 12.84 points to 9042.36 at 03:56 GMT while South Korea's KOSPI index tumbled 1.17 percent or 22.54 points to 1901.96.

China's Shanghai Composite index dropped 0.73 percent or 15.25 points to 2086.33. Hong Kong's Hang Seng index was down 0.46 percent or 99.41 points to 21710.82.

The results came after Apple, the largest company in US by market value, posted weaker than expected quarterly reports. Online retailer Amazon, which competes with Apple in the tablet computer market, also reported revenue that failed to reach estimates.

Concerns about the US re-emerged after data suggested weak business investment in the world's largest economy in September. But the country's labour market continued to show signs of recovery after the weekly jobless claims numbers dropped by 23,000 to 369,000.

Investors remain wary of the Asian quarterly corporate earnings reports as well. Slowing global demand and territorial issues had affected operations of some of the major firms in the region during the period.

Meanwhile, official data from South Korea showed that the country's economic growth slowed to 1.6 percent in the three months ending September from 2.3 percent in the previous quarter. The country has been affected by the falling demand in the US and European markets and its attempts to boost domestic consumption has not been successful.
