NEW YORK, Aug 6 (Reuters) -

The S&P 500 and Nasdaq each rose 2% on Tuesday, while the Dow was up 1% a day after a sharp sell-off as recent comments by Federal Reserve officials eased recession worries.

All major S&P 500 sectors were sharply higher, with technology and real estate up the most.

said

on Monday that last week's disappointing jobs report was not necessarily a recessionary sign.

Nvidia jumped about 7%, giving the biggest boost to the S&P 500 and Nasdaq, a day after falling more than 6%.

"The market had just gotten top heavy, but it did reprice a decent amount, particularly the Nasdaq, and people are coming back to the idea that with lower rates it should provide a support for stocks," said Rick Meckler, partner at Cherry Lane Investments, a family investment office in New Vernon, New Jersey.

The Dow Jones Industrial Average rose 729.82 points, or 1.89%, to 39,433.09, the S&P 500 gained 124.46 points, or 2.40%, at 5,310.79 and the Nasdaq Composite advanced 413.31 points, or 2.55%, to 16,613.39.

Traders are pricing in a 75% chance the Fed will cut rates by 50 basis points at its next policy meeting in September, and a 25% chance of a 25 basis point reduction. A 50 basis point cut was fully priced in on Monday, with a 75 basis point cut also seen possible, the CME Group's FedWatch Tool showed.

Stocks have sold off after weak economic data raised worries of a U.S. recession.

Market concerns were exacerbated as investors wound down yen-funded trades, used to finance acquisition of stocks for years, after a surprise Bank of Japan rate hike last week.

The next big Fed event is Chair Jerome Powell's speech at the Jackson Hole on Aug. 22-24.

Uber shares rose 11.7% after the ride-sharing and food delivery provider beat Wall Street estimates for second-quarter revenue and core profit, helped by steady demand for its services.

Caterpillar added 4% after beating analysts' estimates for second-quarter profit, as higher prices on its larger excavators and other equipment countered moderating demand in North America.

Advancing issues outnumbered decliners on the NYSE by a 3.78-to-1 ratio; on Nasdaq, a 2.88-to-1 ratio favored advancers.

The S&P 500 posted 12 new 52-week highs and five new lows; the Nasdaq Composite recorded 29 new highs and 126 new lows. (Additional reporting by Shubham Batra and Shashwat Chauhan in Bengaluru; Editing by Saumyadeb Chakrabarty, Shinjini Ganguli and Richard Chang)
