June 27 (Reuters) - Wall Street was poised for a lower open on Tuesday as a selloff in technology shares continued, while investors awaited clues on interest rate hikes from Federal Reserve Chair Janet Yellen's talk in London.
The tech sector has been under pressure over concerns about lofty valuations, with investors shifting to high-dividend paying defensive sectors such as utilities in a rising interest rate environment.
The technology index has jumped about 19 percent since the beginning of the year and has been the major force behind the S&P's record-setting rally.
"The indices continue to hover near the very high end of the recent ranges, suggesting this week's end-of-the-quarter window dressing is likely to see more sector rotation," Peter Cardillo, chief market economist at First Standard Financial, wrote in a note.
"The broadening out of the markets, we believe, is essential for the markets to escape a near-term correction."
Yellen is scheduled to take part in a discussion on global economic issues in London at 1 p.m. ET (1700 GMT). Investors expect Yellen to offer more insight into the state of the U.S. economy, which would support the Fed's forecast of a rate hike this year.
Fed officials have signaled that they would look through a slowdown in inflation and continue on their current path for hikes. But investors are skeptical and market pricing shows only a 40 percent chance of a rate hike at the Fed's December meeting.
