U.S. stock index futures indicated a lower open on Monday, as investors digested the latest economic data from China, ahead of some more major third-quarter earnings.

Technology, industrial, health-care and consumer companies all report earnings in the week ahead and may provide some clues on the extent of the U.S. economy's soft patch.

Key earnings before the bell included Halliburton, Morgan Stanley and Hasbro.

IBM, Flextronics, Crown Holdings, Celanese and Six Flags due after the bell.

So far the earnings season has been lackluster, and some high-profile warnings have already given investors pause. Wal-Mart said its sales would be weaker than expected next year, and Yum Brands said its sales in China are too difficult to predict because of volatility there.

Data flow from the U.S. will be dominated by housing market indicators, kicking off on Monday with October's NAHB housing index at 10 a.m. ET.

Meanwhile, September's housing starts figures will be released Tuesday, followed on Thursday by existing home sales data for the same month and the FHFA price index for August.

Additionally, there are a number of Fed speakers in action this week, with Federal Reserve Governor Lael Brainard speaking on regulatory burden at 10 a.m. and Richmond Fed President Jeffrey Lacker due to speak at noon.

When the Fed held off hiking interest rates in September, it warned that it was watching international developments because of the potential impact on U.S. growth.

European markets traded higher on Monday after Chinese growth figures confirmed slowing growth in the world's second-largest economy, but beat expectations.

China's gross domestic product (GDP) growth slowed to 6.9 percent in the third quarter of 2015 from a year earlier, according to official data, higher than many expected but still the slowest growth since the global credit crisis.

Asian stock markets had a mixed reaction to the news, with the Shanghai Composite up slightly but both the Nikkei and the Hang Seng down, as the GDP data included worse than expected industrial production figures.
