The Dow and the S&P 500 closed at new record highs Thursday on robust corporate earnings reports and the latest reaffirmation of the Federal Reserve's easy-money policy.

The Dow Jones Industrial Average rose 78.02 (0.50 percent) to 15,548.54.

The broad-market S&P 500 ended 8.46 (0.50 percent) higher at 1,689.37.

The rally solidly topped both indices' prior closing records set Monday of

15,484.26 on the blue-chip Dow and 1,682.50 on the S&P 500.

The tech-rich Nasdaq Composite Index, meanwhile, eked out a gain of 1.28

(0.04 percent) to 3,611.28 after some disappointing earnings reports, including from Dow member Intel.

The new records followed a second day of congressional testimony from Federal Reserve Ben Bernanke that came and went with no bombshells. Bernanke reiterated that the Fed plans to scale back its bond-buying program, but only when the economy improves.

Dow component UnitedHealth Group shot up 6.5 percent after profits were $1.40 per share compared with projections of $1.25.

Two large banks in the Dow, Bank of America and JPMorgan Chase, rose by 3.1 percent and 2.0 percent, respectively, after peer Morgan Stanley became the latest big financial company to beat earnings estimates by a large margin.

Morgan Stanley leaped 4.4 percent.

But chip-maker Intel sank 3.8 percent as declining personal computers demand trimmed profits by 29 percent.

Other Dow decliners included Verizon (down 1.5 percent) and American Express (down 3.6 percent).

Dell jumped 1.9 percent after postponing a shareholders vote on a go-private proposal in the face of criticism.
