The S&P 500 rose to a fresh record-high on Tuesday and largely shook off a weak consumer confidence reading thanks to a sharp rise in Nvidia. The broad market index inched up 0.2%. The Dow rose as much as 110.34 points to hit an all-time high earlier in the session, but was last up 17 points, or 0.04%. The Nasdaq Composite added 0.5%. Shares of artificial intelligence darling Nvidia climbed more than 4% alongside the broader field of chip stocks. Consumer confidence suffered its biggest one-month decline in more than three years, hitting 98.7 for September. Economists polled by Dow Jones expected a reading of 104. The data follows a warning from JPMorgan Chase CEO Jamie Dimon about geopolitical instability “getting worse” and being his “biggest caution.” Dimon added that the worrisome backdrop could influence “the state of the economy” moving forward. “Essentially when you take them both together, they keep the wall of worry built,” Evercore ISI senior managing director Julian Emanuel told CNBC’s “Squawk on the Street” on Tuesday. “We would be more concerned if we started hearing everything’s great [or] everything’s roses.” China stocks stood out on Tuesday following stimulus efforts from Beijing to stoke economic growth. Shares of U.S. listed Alibaba and JD.com climbed 5% and 8%, respectively. Industrial stock Caterpillar advanced more than 3%. Despite Tuesday’s moves, the major averages were headed for solid monthly gains. The Dow was up 1.4% in September. The S&P 500 and Nasdaq have risen 1% and 1.2%, respectively. Some of those gains come as investors grow hopeful that lower rates from the Federal Reserve will drive economic growth and boost profits.

Paulson shot to fame and made a fortune after taking a massive bet against mortgage bonds using credit default swaps before the financial crisis. The founder and president of family office Paulson & Co. just last week warned of a market “crash” if Harris’ proposed tax plans become a reality. “If something comes to a change — the tax policy or the direction of the economy — I think the markets would be vulnerable,” he said. — Yun Li Visa, Smartsheet among the names making moves midday Here are some stocks making big moves in midday trading: Visa — Shares dropped nearly 4% following a Bloomberg report that the Justice Department is preparing to file an antitrust lawsuit against the credit card network and payments processor.Smartsheet — Shares surged more than 6% after Blackstone and Vista Equity Partners agreed to buy the software maker for $56.50 a share in cash, or about $8.4 billion.

On the contrary, positive EPS surprises have been met with typical stock price responses,” the analysts, led by Renate Marold, wrote in the Tuesday report. — Lisa Kailai Han Consumer confidence misses big Spencer Platt | Getty ImagesA woman walks by a store window displaying dresses in Brooklyn, New York City, on Aug. 14, 2024. The Conference Board said Tuesday that its consumer confidence index fell sharply in September, putting pressure on equities. The index came in at 98.7, down from an upwardly revised August reading of 105.6. That is also well below a Dow Jones consensus forecast of 104. “September’s decline was the largest since August 2021 and all five components of the Index deteriorated. Consumers’ assessments of current business conditions turned negative while views of the current labor market situation softened further. Consumers were also more pessimistic about future labor market conditions and less positive about future business conditions and future income,” Dana Peterson, chief economist at the Conference Board, said in a statement. — Fred Imbert Caterpillar pops after China unveils news stimulus Caterpillar shares were up more than 3% on Tuesday after the Chinese central bank unveiled new stimulus measures to support the country’s economy.

Chinese stocks soared after the country’s central bank unveiled new stimulus to spur economic growth. Adam Crisafulli of Vital Knowledge called the easing measures the biggest news out of the overnight session. “The news is undoubtedly bullish for Chinese stocks (and cyclical/industrial sentiment broadly), although many are adopting a dismissive “here we go again” attitude toward the headlines, lamenting the scope and scale of the actions and anticipating a reversal of the present euphoria within a few days or weeks,” he wrote. “We’re not quite as cynical — the volume and coordinated nature of China’s stimulus steps overnight may not qualify as ‘bazooka’, but it’s close. — Fred Imbert Small caps to grow at a multiple of the ‘Magnificent Seven,’ says Richard Bernstein Small caps are poised to see massive gains over the next few months, according to Richard Bernstein of Richard Bernstein Advisors. “The reason, I think, that we’re such big bulls on mid-caps and small caps is that that’s where the earnings growth is forecasted to be,” the firm’s CEO and chief investment officer told CNBC’s “The Exchange” on Monday. “By the end of this year [or] early next year, we’re going to find that small caps … are going to grow at a multiple of what, say, the ‘Magnificent Seven’ are going to grow at.” He added that while this small-cap performance is not particularly unusual in a trough, it is unusual for it to be happening when the Federal Reserve is “actually easing into this accelerating profits environment” rather than tightening. “As profits rev up, we should see, normally, the economy just gets stronger, naturally,” he continued. “Now we’ve got the Fed easing on top of that. That’s like putting fuel on the fire.” When looking at deglobalization as a key investment theme, Bernstein anticipates that midcap industrial stocks that have a focus on the U.S. economy in particular will be the “big growth beneficiaries.” “As globalization contracts, we have to realize that it’s not just semiconductors that open up the United States to national security implications,” he said. “It’s the fact that we don’t produce anything here in the United States. That’s basically what our trade deficit shows. We think that presents a tremendous opportunity.” — Sean Conlon Stocks making the biggest moves after hours Check out the companies making headlines in extended trading: Snowflake — Shares of the data cloud company fell 3% after Snowflake announced a proposed private placement of $2 billion of convertible senior notes.AAR — The defense stock rose nearly 4%.
