Hong Kong stocks closed mixed on Friday on less than impressive industrial data and a decrease in the urban unemployment rate, despite a growth recorded in China's industrial output and consumer goods sales.

The industrial data missing the market expectations added to the worries of investors who are already burdened with concerns regarding trade tensions with the US, and the overall economic situation of the region.

The Hang Seng Index fell marginally by 0.05%, or 9.47 points, to close Friday's session at 19,426.34. The Hang Seng China Enterprises Index, however, rose by 0.10%, or 6.98 points, to close at 6,980.06.

The National Bureau of Statistics published a series of data on Friday, including China's industrial output, which rose 5.3% year over year in October, easing from the 5.4% growth in September and missing market expectations.

The retail sales of consumer goods rose 4.8% year over year to 4.540 trillion yuan in the same month, faster than the 3.2% rise logged the previous month, while the urban unemployment rate stood at 5%, down 0.1 percentage points from September.
