May 1 (Reuters) - Wall Street rose at the open on Friday as healthcare and technology stocks, led by Gilead and Apple, rebounded after two weak sessions, and despite data that came in lower-than-expected.
A majority of the 10 major S&P indexes were higher, with the health and tech both snapping a 2-day losing streak. Apple shares rose 1.5 percent to $126.94 and was the biggest driver on the Dow, Nasdaq and S&P 500.
The Nasdaq biotech index was up 2.6 percent, snapping a 5-day losing streak and on track for its best day since April 8.
Gilead led the gains with a 3 percent increase to $103.53 after its quarterly profit nearly doubled, driven by strong sales of its hepatitis C drugs. The stock was the second-largest boost on the S&P 500 and the Nasdaq.
"Its a new month and big institutional investors that allocate on a monthly basis are still moving money into the market," said Adam Sarhan, chief executive of Sarhan Capital in New York.
The jump in the equity markets comes despite data showing that construction spending fell in March to a six-month low, while manufacturing growth held at its slowest in almost two years in April.

Yum Brands jumped 5.5 percent to hit a record high of $90.70 after Daniel Loeb's Third Point revealed a stake in the company and said the KFC-owner had "turned the page" on its China troubles and forecast a dramatic profit recovery.
CVS climbed 1.6 percent to $100.85 after it reported a better-than-expected quarterly profit.
