US STOCKS-Wall St gains after Fed indicates more rate cuts; Intel soars

Sept 18 (Reuters) - Wall Street's main indexes hit intraday record highs on Thursday, a day after the U.S. Federal Reserve delivered a quarter-point interest rate cut, while chipmaker Intel rose after Nvidia decided to build a stake in the company.

Intel INTC.O jumped 23.1%, set for its biggest daily gain since October 1987 after Nvidia NVDA.O said it would invest $5 billion in the struggling U.S. chipmaker. Peer Advanced Micro Devices AMD.O slipped 2.3%.

Nvidia gained 3.6%, recovering losses from Wednesday when a report said Chinese tech firms might stop buying its chips.

The semiconductor stock moves boosted a broader semiconductor .SOX index 3.6% to a record high. The gains also lifted the tech-heavy Nasdaq and the S&P 500 technology sector .SPLRCT, up 1.3%. Eight out of the 11 S&P 500 sectors rose.

The small-cap Russell 2000 index .RUT gained 2.2% and touched an intraday record high of 2,466 points for the first time since November. Small-cap companies are likely to perform better in a low interest-rate environment.

On Wednesday, Fed Chair Jerome Powell emphasized that the softening jobs market was a priority and indicated more reductions could follow at upcoming policy meetings.

"We are looking for support for economic growth and justification of stretched valuations and the prospect of lower interest rates helps that," said Sam Stovall, chief investment strategist at CFRA Research.

At 02:20 p.m. the Dow Jones Industrial Average .DJI rose 146.47 points, or 0.32%, to 46,164.79, the S&P 500 .SPX gained 36.97 points, or 0.56%, to 6,637.43 and the Nasdaq Composite .IXIC gained 228.77 points, or 1.03%, to 22,490.27.

Conversely, the S&P 500 energy .SPNY and consumer staples .SPLRCS were the biggest decliners, down 0.62% and 0.79% respectively.

New data showed that the number of Americans filing new applications for unemployment benefits fell last week, but the labor market has softened as both demand for and supply of workers have diminished.

The rate cut is expected to add to Wall Street's recent rally, boosted by monetary policy easing hopes and a revival of AI-linked stock trading. Investors are pricing in about 44.4 basis points in cuts by end-2025, data compiled by LSEG showed.

Among stocks, CrowdStrike CRWD.O gained 12.4% after at least nine brokerages raised their price target on the stock.

Shares of Darden Restaurants DRI.N fell 7.8% after the Olive Garden parent reported weak quarterly results.

Advancing issues outnumbered decliners by a 1.77-to-1 ratio on the NYSE, and by a 2.46-to-1 ratio on the Nasdaq.

The S&P 500 posted 30 new 52-week highs and seven new lows while the Nasdaq Composite recorded 138 new highs and 36 new lows.
