May 26 (Reuters) - Wall Street opened lower on Tuesday after the dollar jumped to a one-month high on data showing that U.S. business investment spending plans increased solidly for a second straight month in April.
Federal Reserve Chair Janet Yellen said on Friday that the central bank could raise interest rates this year if the economy keeps improving as expected.
The dollar was hovering at an eight-year high against the yen and a one-month peak against a basket of other big currencies.
"It isn't normal to see such large moves in currencies," said Adam Sarhan, chief executive of Sarhan Capital in New York.
"Such moves heightens volatility in the market."
Non-defense capital goods orders excluding aircraft, a closely watched proxy for business spending plans, rose 1.0 percent last month, a hopeful sign for manufacturing activity after a recent long spell of weakness.
That was followed by data that showed single-family home prices in the United States rose more than expected in March from a year earlier, led again by strong increases in the western half of the country.
