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.
U.S. stock futures, meanwhile, traded firmer in morning London trade, with Dow Jones industrial average futures climbing more than 100 points.
