Wall St Week Ahead: Tech rally may be getting stretched

NEW YORK: A blistering rally in US big tech stocks may be due for a breather, offering hope for market segments that have been more tepid this year.

Although the S&P 500 is up 14.6% this year, most of the broader index's gains have been concentrated in the information technology and communications sectors - up 28.2% and 24.3%, respectively. The rest of the market has been more subdued: the next best performing sector, utilities, is only up 9.5% year-to-date.
