U.S. stock index futures were little changed on Monday in the wake of eight straight weeks of gains after mixed data on China and the euro zone and ahead of U.S. economic reports which could provide some clues on the strength of the recovery.

Final data for China's HSBC/Markit Purchasing Managers' Index showed factory activity maintained steady growth momentum in November, boosted by resilient new orders, though the pace of expansion eased slightly from October.

In the euro zone, buoyant demand for manufactured goods drove factory activity to accelerate at its fastest pace in over two years last month. But growth was still weak, and Markit said evidence of a renewed downturn in France and Spain - as well as firms cutting staff - was disappointing.

Markit is expected to release its final U.S. manufacturing PMI for November at 8:58 a.m. ET. The index read 54.3 in the flash November report.

Later in the session at 10 a.m. ET investors will eye the September and October construction spending data along with the Institute for Supply Management's November manufacturing PMI report. Economists in a Reuters survey expect a 0.4 percent increase in October construction spending and a 55 reading in the ISM manufacturing index.

While the Fed's stimulus program is expected to put a floor under equity prices for as long as it continues, market participants expect the central bank to begin scaling back its bond buying program within the next few months, with many expecting an announcement in March.

The central bank has said it would begin to slow the program when certain economic measures meet its targets. The calendar is packed this week with data that may provide some insight, culminating with the November payrolls report on Friday.
