U.S. stocks were tipped to open higher on Tuesday, recovering some of the previous day's falls, ahead of the start of the U.S. Federal Reserve's two-day meeting, a raft of earnings and data.
China remained in focus, with Shanghai's benchmark stock market closing down 1.7 percent after another volatile session that saw shares shed as much as 5 percent. China's securities regulator said on Tuesday that it had launched an investigation into Monday's selloff, when stocks fell more than 8 percent.
Still, global markets appeared to brush off the turmoil for now with Asian stocks outside China edging higher and European stock markets opening in positive territory.

The Fed, meanwhile, kicks off its two-day meeting later in the day. Although markets are not anticipating any changes to interest rates this week, any hawkish comments from the central bank's post-meeting statement on Wednesday could fuel talk of a September rate move.
U.S. interest rates have been held near zero since the global financial crisis, but with the economy in recovery mode, investors have tipped 2015 as they year the Fed will deliver its first rate hike in almost a decade.
"Last time, (Fed Chair Janet) Yellen, spooked the market with speculations that a rate hike will most probably will take place in September and this is pushing the dollar higher and making the dollar denominated commodities rout even worse," Naeem Aslam, chief market analyst at AvaTrade, said in a note.
"Nonetheless, the Fed will surely bring the Chinese selloff and commodity rout under their consideration and will tailor their response accordingly," he added.
The plunge in Chinese stock markets has raised concerns about financial stability and a protracted economic slowdown in the world's second biggest economy that would have knock-on effect on global growth.
