Aug 21 (Reuters) - U.S. stock index futures rose on Tuesday, helped by some encouraging earnings reports and hopes that planned trade talks between the United States and China will help resolve the dispute between the world's two largest economies.
The trade optimism helped Wall Street's three major indexes close higher on Monday, though they fell from session highs after President Donald Trump criticized the Federal Reserve for raising interest rates.
Trump told Reuters he was "not thrilled" with the Fed under his own appointee, Chairman Jerome Powell, for raising rates and said the central bank should do more to help him to boost the economy.
While Trump does not expect much progress from the mid-level trade discussions with China later this week in Washington, his comments on the Fed pushed the dollar lower on Tuesday and propped up prices of metals and crude oil.
"There is continued optimism falling through from yesterday that things cannot be all that bad. So the focus is now on the economy," said Andre Bakhos, managing director at New Vines Capital LLC, Bernardsville, New Jersey.
"Today will probably be on the quiet side, drifting a little higher, but overall what we are going to see ahead is an upward trend mixed with some choppy, erratic trading."
At 8:53 a.m. ET, Dow e-minis were up 45 points, or 0.17 percent. S&P 500 e-minis were up 4.25 points, or 0.15 percent and Nasdaq 100 e-minis were up 16.25 points, or 0.22 percent.
With the earnings season winding down, investors are turning their attention to central bank policies this week.
The minutes of Fed's August policy meeting on Wednesday are expected to indicate the central bank's confidence in economic growth and commitment to future rate hikes. That comes ahead of the global central bankers' meet in Jackson Hole, Wyoming, from Friday.
Shares of bank stocks rose in premarket trading. JPMorgan Chase & Co, Bank of America and Citigroup and Morgan Stanley were up between 0.3 percent and 0.6 percent.
Online brokers Charles Schwab, E*Trade Financial and TD Ameritrade tumbled between 3.5 percent and 6.2 percent after CNBC reported JPMorgan planned to roll out a free digital brokerage service next week.
Apple gained 0.5 percent to $216.50 after BofA Merrill Lynch raised its price objective on the iPhone maker to $250.
Among companies reporting earnings, Coty fell 4.8 percent after the beauty products maker missed sales estimates for the first time in six quarters as a trucker strike in Brazil disrupted supplies.
Kohl's fell 3 percent as the mid-point of its raised full-year earnings forecast fell short of analyst' estimates despite strong quarterly results.
Medtronic rose 4.4 percent after the medical device maker's profit beat estimates on higher sales in its top-selling cardiac and vascular unit.
Toll Brothers Inc jumped 9.1 percent after the luxury homebuilder topped quarterly estimates. PulteGroup , Lennar and D.R. Horton rose more than 2 percent. (Reporting by Shreyashi Sanyal in Bengaluru; Editing by Anil D'Silva)
