April 24 (Reuters) - The Nasdaq Composite and S&P 500 chalked up record high closes on Friday, propelled by strong results from tech behemoths Google, Amazon and Microsoft.
The Nasdaq Composite added 0.71 percent to end at 5,092.09, its second straight record high close. The S&P 500 rose 0.23 percent to a record high close of 2,117.69 points, barely above its previous high of 2,117.39 set on March 2.
Amazon surged 14.13 percent to a lifetime high after revenue beat estimates.
Google ended 2.9 percent after reporting higher quarterly results while Microsoft jumped 10.45 percent after it topped estimates.
The S&P had hit an intraday high of 2,120.92. The Nasdaq earlier reached 5,100.371, the highest since its intraday record of 5,132.52 in March 2000 that marked the peak of the dot-com bubble.
"This chapter that the Nasdaq is writing is more suggestive that it's a market that, while still technology-weighted, is much more mature," said Steven Baffico, chief executive officer at Four Wood Capital Partners in New York. "The companies in it reflect that, companies like Cisco and Microsoft."
Microsoft, Amazon, Google and Starbucks accounted for the bulk of the Nasdaq's rise on Friday.
The Dow Jones industrial average closed up 21.45 points, or 0.12 percent, to 18,080.14. The S&P 500 gained 4.76 points and the Nasdaq Composite added 36.02 points.
For the week, the S&P gained 1.8 percent, the Nasdaq gained 3.3 percent and the Dow added 1.4 percent.
"This is a case of the equity market looking a little bit forward to oil being less of a drag going forward, and that earnings in the second half will be better than they are now," said Anthony Valeri, an investment strategist for LPL Financial in San Diego.
While markets are at record highs, March-quarter earnings of S&P 500 companies are expected to dip 1.3 percent, with revenues dropping 3.5 percent as the dollar hurts U.S. multinationals and low oil prices affect energy companies, according to Thomson Reuters data.
Xerox slumped 8.75 percent after it cut its 2015 profit forecast, blaming the strong dollar.
Time Warner Cable jumped 4.37 percent on news Charter Communications Inc's representatives reached out to begin discussions on a potential merger. Comcast earlier abandoned its proposed $45 billion merger with Time Warner Cable.
Apple could be among the biggest market drivers when it reports results after the bell on Monday. Results next week from several big energy names, including Exxon Mobil and Chevron, could keep investors on edge.
