Nov 21 (Reuters) - Wall Street indexes hit record intraday highs on Tuesday, lifted by technology stocks and healthcare shares, which were boosted by bullish results from medical device maker Medtronic.
The S&P technology index rose 1 percent, helped by gains in Apple. The index has risen 38 percent this year, far outperforming other major sectors and the broader S&P 500.
"It is a return of momentum for the market, with some of positive earnings and recommendations as catalysts," said Eric Wiegand, senior portfolio manager at U.S. Bank's Private Client Reserve unit.
"They (technology stocks) have been in the leadership position for long and have produced remarkable earnings growth. With the sector also standing to benefit from tax reforms, they will continue to be in a favored position," Wiegand said.
At 12:35 p.m. ET (1635 GMT), the Dow Jones Industrial Average was up 178.7 points, or 0.76 percent, at 23,609.03, the S&P 500 was up 16.91 points, or 0.65 percent, at 2,599.05 and the Nasdaq Composite was up 63.26 points, or 0.93 percent, at 6,853.98.
