NEW YORK MarketWatch) -- U.S. stock shook off early morning gloom and moved decidedly higher on Thursday, with the blue-chips leading the gains.

The Dow Jones Industrial Average gained more 150 points, thanks to a a jump in its largest component, Visa Inc.. The benchmark S&P 500 followed the Dow, albeit with smaller gains.

Investors are digesting robust economic reports, a day after the Federal Reserve officially announced the conclusion of its bond-purchasing initiative.

Confirming the Fed's optimistic view on the economy, the first reading of third-quarter GDP came in better than expected, expanding at 3.5% annualized rate. Weekly jobless claims ticked up, however, claims remain below the 300,000, pointing to an improving labor market.

The S&P 500 index (SPX) and Nasdaq Composite (RIXF) were slightly higher.
