(Reuters) - The Nasdaq rallied on Thursday, lifted by gains in Nvidia (NASDAQ:NVDA) and other technology-related stocks as investors focused on the Federal Reserve's Jackson Hole conference for clues about the central bank's policy outlook.

Fed Chair Jerome Powell is due to give a speech on Friday that investors will dissect for indications of how aggressively the Fed may move to raise interest rates as it battles decades-high inflation.

"We're in a period of time between the end of the second-quarter earnings season and meaningful additional data from the Federal Reserve. Markets are churning a bit with a reasonably low level of volatility," said Bill Northey, senior investment director at U.S. Bank Wealth Management in Minneapolis.

The yield on the closely watched 10-year Treasury note faded after recently hitting a two-month high. Declining interest rates tend to benefit technology stocks trading at high valuations.

"Lower interest rates have certainly put some support underneath some of the more growth-oriented sectors," Northey said.

Nvidia rose 2.8% after the chipmaker gave a weaker-than-expected quarterly forecast that many investors viewed as signaling the worst of a sales downturn may be over. That drove a 2.9% rally in the Philadelphia semiconductor index.

Apple (NASDAQ:AAPL), Amazon (NASDAQ:AMZN) and Google-owner Alphabet (NASDAQ:GOOGL) rose more than 1% each, and they all made substantial contributions to the Nasdaq's increase.

Data earlier in the day showed the U.S. economy contracted less than initially thought in the second quarter, dispelling some fears that a recession was underway.

Fed officials on Thursday were noncommittal about the size of the interest rate increase they plan to approve at their Sept. 20-21 meeting, but they continued hammering the point that rates will rise and stay high until such high rates of inflation has been squeezed from the economy.

Electric-vehicle maker Tesla (NASDAQ:TSLA) Inc slid almost 1% after its 3-for-1 stock split came into effect.

In afternoon trading, the S&P 500 was up 0.79% at 4,173.32 points.

The Nasdaq gained 1.12% to 12,570.65 points, while the Dow Jones Industrial Average was up 0.37% at 33,091.39 points.

Of the 11 S&P 500 sector indexes, nine rose, led by communication services, up 1.49%, followed by a 1.42% gain in materials.

Citigroup Inc (NYSE:C) rose 2% after saying it plans to close its consumer and commercial banking businesses in Russia starting this quarter.

Salesforce (NYSE:CRM) Inc fell 4.6% after it cut its annual forecasts over "measured" spending from clients and a hit from a stronger dollar.

Additional chipmakers rising on Thursday included Advanced Micro Devices (NASDAQ:AMD), up 4.3%, and Broadcom (NASDAQ:AVGO), gaining 2.8%.

Advancing issues outnumbered falling ones within the S&P 500 by a 4.2-to-one ratio.

The S&P 500 posted 3 new highs and 29 new lows; the Nasdaq recorded 47 new highs and 58 new lows.
