Wall Street opens higher ahead of Fed's minutes

U.S. stock indices opened little changed but mostly higher on Tuesday after earlier U.S. data showed a steeper-than-expected drop in existing home sales last month, while markets await the Federal Reserve's minutes for the last meeting. 

Investors are looking for confirm whether the Fed will tighten the policy in the June meeting, after voting to hold interest rates at between 0.75% and 1.00% in the last meeting after growth slowed down to a 3-year low in the first quarter. 

A spate of disappointing U.S. data, sans the labor sector data, curbed the bets on a Fed rate hike by 25 basis points in the next meeting to a range of 1.00%-1.25%. 

Similarly, markets are waiting for more details about the Federal Reserve's efforts to cut its balance sheet of $4.5 trillion in the next period, after president Donald Trump unveiled his first full budget plan, aiming to cut government spending by $3.6 trillion and balance the budget by the next decade. 

As of 03:28 GMT, Standard and Poor's 500 rose 0.10%, or 2.41 points to 2,400.83, while Dow Jones gained 0.17%, or 38.01 points to 20,975.92. 

Tech-heavy NASDAQ advanced 0.12%, or 7.50 points to 6,146.21.
