(Reuters) - U.S. stocks recorded their steepest fall in three weeks in morning trading on Tuesday as positive economic data added to the gains in the dollar and sent it soaring to a one-month high.
The dollar was hovering at an eight-year high against the yen and a one-month peak against a basket of other big currencies.
"A strong dollar is going to hurt exports and the revenue line of companies, which wasn't strong to begin with," said Rick Fier, director of trading at Conifer Securities in New York.
The overall economy is gradually firming, with reports on Tuesday showing business investment spending plans increasing solidly in April, consumer confidence perking up this month and house prices extending gains in March.
The buoyant data comes after 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 comments kept the likelihood of a September rate increase high.
