Technology and energy companies lift US stocks to record highs
US stocks have continued to climb, led by technology, healthcare and energy companies.
Media firms also rose as stock indexes set record highs.
The technology part of the Standard & Poor's 500 index finally broke the record it set in March 2000, before the dot-com bubble burst.
Energy companies rose with the price of oil as US energy stockpiles continued to shrink.
Cable network companies Scripps Networks and Discovery Communications jumped after the Wall Street Journal reported that they are in talks to combine.
Stocks have been setting records for most of this year and over the last few months they've had a boost from a recovery in corporate profits.
"Earnings are coming in better than expected so far," said Jon Adams, senior investment strategist for BMO Global Asset Management. "Technology in particular has come in very strong."
The Standard & Poor's 500 index rose 13.22 points, or 0.5%, to 2,473.83.
Despite a sharp drop from IBM, the Dow Jones industrial average added 66.02 points, or 0.3%, to 21,640.75.
The Nasdaq composite gained 40.74 points, or 0.6%, to 6,385.04.
The Russell 2000 index of smaller-company stocks jumped 14.16 points, or 1%, to 1,441.77. All four indexes closed at record highs.
The S&P 500 technology index finally surpassed its peak from late March 2000, at the height of the dot-com boom.
That index came close to an all-time high in early June, but after that technology companies went into decline that lasted about a month. Their recovery over the last two weeks has helped the Nasdaq composite pull off a rally as well.
Bond prices inched lower while the yield on the 10-year Treasury note rose to 2.27% from 2.26%.
