The S&P 500 hits new high on Thursday as renewed enthusiasm for artificial intelligence stocks pushed U.S. equities higher, while softer inflation data reduced concerns about another Federal Reserve rate hike.
The benchmark S&P 500 closed at a record 7,798.99, gaining 0.65% on the day. The index also reached a fresh intraday record as technology and AI-related stocks attracted renewed buying interest.
The S&P 500 hits new high as investors increasingly focus on the potential economic and earnings benefits of artificial intelligence, while expectations for stable U.S. interest rates provide additional support for risk assets.
The latest rally has once again placed artificial intelligence at the centre of the U.S. stock market story.
Technology companies linked to AI infrastructure and semiconductor demand were among the strongest performers. Sandisk surged 13.7%, while Micron gained 4.2%. Microsoft also rose nearly 1%, while Meta advanced 2.8%.
The S&P 500 hits new high as investors continue to assess whether massive spending on AI infrastructure can translate into stronger corporate earnings and cash flows.
Recent earnings reports have helped reinforce optimism around AI demand. Investors are particularly focused on semiconductor manufacturers, cloud providers and companies supplying the infrastructure needed to support increasingly sophisticated AI systems.
The renewed strength in AI stocks has helped push the broader index higher, although investors remain aware that a relatively concentrated group of technology companies continues to account for a significant portion of the market's gains.
Another major driver behind the S&P 500 hits new high move was the latest U.S. inflation data.
The Producer Price Index remained unchanged month-over-month in July, easing concerns that inflationary pressures were accelerating again. The data followed a softer consumer inflation report, with annual consumer inflation previously slowing to 3.4% in July from 3.5% in June.
The combination of softer inflation and strong corporate earnings gave investors more confidence that the Federal Reserve may be able to avoid further interest-rate increases.
Markets are now placing greater emphasis on the possibility of the Fed keeping interest rates unchanged at its September meeting.
That outlook has supported stocks because lower or stable borrowing costs can make equities more attractive relative to cash and fixed-income assets.
The S&P 500 hits new high as Treasury yields retreat following the softer inflation data.
The 10-year U.S. Treasury yield fell to around 4.64%, moving lower from its late-July highs. Falling yields can provide additional support for growth and technology stocks because the future earnings of these companies become relatively more attractive when discount rates decline.
The U.S. dollar also weakened slightly during the session, adding another layer of support for risk sentiment.
For currency traders, the combination of lower Treasury yields, a softer dollar and stronger equities is an important market signal. It suggests investors are becoming less concerned about an immediate return to aggressive monetary tightening.
The S&P 500 hits new high alongside another strong performance from the Nasdaq Composite.
The Nasdaq gained approximately 0.81%, closing at 26,803.03, while the Dow Jones Industrial Average increased around 0.13% to 53,839.99.
The stronger performance from the Nasdaq highlights the continued importance of technology stocks in the current market rally.
Communication services and technology-related companies were among the sectors supporting the broader market. Seven of the S&P 500's 11 sectors finished higher during the session.
However, the rally was not universal.
Cisco dropped 8.4% despite providing upbeat revenue guidance, while Tapestry fell more than 16% after issuing disappointing revenue projections.
These contrasting performances show that investors remain selective despite the broader bullish environment.
The S&P 500 hits new high at a time when investors are balancing two powerful themes: continued AI optimism and changing expectations for Federal Reserve policy.
If inflation continues to cool while corporate earnings remain strong, equities could receive further support. Lower inflation would give the Fed more flexibility to maintain or eventually reduce borrowing costs without risking a renewed inflation surge.
AI spending could provide another source of momentum.
Investors are watching whether companies can turn their enormous AI investments into measurable revenue growth and stronger profits. The market's next major test will come from upcoming earnings reports and guidance from major technology companies.
Nvidia's upcoming earnings on August 26 will be particularly important for the AI trade, given the company's position at the centre of the AI semiconductor market.
The S&P 500 hits new high with the index closing at 7,798.99, marking another milestone for U.S. equities.
The immediate outlook remains closely tied to three factors: AI earnings momentum, Federal Reserve expectations and incoming inflation data.
A continued decline in inflation could strengthen expectations that the Fed will keep rates steady in September, potentially supporting further gains in technology and growth stocks.
Meanwhile, sustained AI investment and strong earnings could keep investor enthusiasm elevated.
However, the record level also means expectations are high. Any disappointment from major technology companies, a renewed rise in inflation or a hawkish shift from the Federal Reserve could quickly test the market's current momentum.
For now, the S&P 500 hits new high as Wall Street embraces renewed AI enthusiasm and a more favourable interest-rate outlook.
With the index now approaching the 7,800 level and AI stocks once again leading the rally, investors will be watching closely to see whether the record-breaking move can continue or whether elevated valuations begin to create resistance.
