Apple shares jumped as much as 2.1 percent to a record high of $146.68, boosting all the three major Wall Street indexes. Apple is due to report its results on Tuesday.
The S&P 500 technology index was up 0.66 percent, with Microsoft and Facebook also hitting all-time highs. Including the tech sector, five of the 11 major S&P 500 sectors were higher.
The other sectors were kept in check by weak construction spending and manufacturing data that came on the heels of weak first-quarter GDP data on Friday and ahead of the monthly jobs data at the end of this week.
U.S. Secretary of the Treasury Steve Mnuchin said it could take up to two years to have economic growth reach three percent and that tax cuts and regulatory relief would help get there.
Construction spending unexpectedly fell in March amid a pause in private construction investment after five straight months of increases.
Other data showed the ISM manufacturing activity index fell to its lowest level since December, while consumer spending was unchanged for a second straight month in March and a key inflation measure recorded its first monthly drop since 2001.
The industrials and materials indexes were little changed.
“The economic data today is causing some investor nervousness ahead of the jobs report this Friday,” said Matt Miskin, senior capital markets research analyst at John Hancock Investments in Boston.

Trading volume is expected to be light, with many markets in Asia and Europe closed for Labor Day, but will pick up through the week as major earnings reports and economic data pour in.
