Aug 9 (Reuters) - Wall Street extended gains on Tuesday as healthcare and technology stocks powered the S&P 500 and the Nasdaq to record highs.
The S&P 500, which marked its fourth all-time high this month, rose to 2,187.33, while the Nasdaq touched an all-time high of 5,235.93.
The S&P 500 index's healthcare index rose 0.49 percent, helped by a 26 percent jump in Endo International and a 3 percent rise in Mylan.
The information technology index rose 0.35 percent, lifted by a 7.4 percent rise in Charter Communications and a 0.6 rise in Amazon.com.
"It has been an unloved rally, and one that has not been met by the infamous 'animal spirit'," said Eric Wiegand, senior portfolio manager at the Private Client Reserve at U.S. Bank in New York.
"There is no euphoria that is accompanying this move higher. It has been very measured and somewhat technical in support."
The S&P 500 closed 0.2 percent away from its all-time high on Monday and the Nasdaq closed 0.3 percent shy.
