S&P 500, Dow hit fresh highs

The S&P 500 and Dow Jones Industrial Average climbed to fresh highs on Tuesday, August 4, as investors poured into large-cap technology and AI-linked stocks after a run of strong earnings. The S&P 500 closed at 7,736.52, up 1.79%, while the Nasdaq Composite rose 2.59%, according to CNBC’s market coverage. Palantir Technologies led the move with a 29% jump, and Arm Holdings rose more than 17% as traders rewarded companies tied to AI spending. (cnbc.com) Thursday’s tone was more restrained. Futures were flat to softer ahead of fresh U.S. employment data, with investors waiting for clearer signals on growth and inflation after the rally earlier in the week. (fxstreet.com) The rebound has also tracked lower oil prices as fears around Middle East supply disruptions eased from spring peaks. ### Why did Palantir and Arm matter so much to this move? Palantir’s August 3 earnings report gave traders one of the week’s clearest catalysts. CNBC reported that Palantir posted second-quarter results above Wall Street estimates, with revenue up 93% year over year and U.S. commercial revenue up 149%. (cnbc.com) That helped drive the stock’s outsized gain the next session and reinforced demand for companies seen as direct AI beneficiaries. Arm also became part of the same trade. Market reports cited by search results said Arm shares rose more than 17% as investors extended the AI earnings theme across chip and infrastructure names. (home.treasury.gov) The move fit a broader pattern in which traders favored companies tied to computing demand rather than the wider market evenly. ### How much of the rally came from earnings, and how much came from oil? Tuesday’s record close coincided with another drop in oil prices. CNBC said hopes that the Strait of Hormuz could reopen helped push crude lower, easing one of the market’s biggest inflation and growth worries. (cnbc.com) That gave investors room to lean harder into risk assets just as earnings from AI-linked companies were surprising to the upside. The Treasury Borrowing Advisory Committee gave the official version of that backdrop on August 5. In its report to the Treasury secretary, the committee said the Iran conflict and energy prices had been the dominant force in global markets since early May, and that Brent crude had peaked near $126 in the spring before a fragile ceasefire and de-escalation pushed prices down into the low $70s through June.

Mary Daly, president of the San Francisco Federal Reserve Bank, said on Thursday that tariffs had clearly lifted inflation but that there were early signs the effect was starting to fade. (cnbc.com) That comment mattered because investors are trying to judge whether cooling tariff pressure could give the Fed more flexibility if growth slows. At the same time, Thursday’s flat futures showed traders were not treating the rally as risk-free. The next labor-market data became the immediate test, because a hotter or weaker-than-expected jobs print could shift expectations for rates, growth and corporate earnings. (home.treasury.gov) That left the market balancing strong company results against unresolved macro risks. ### What does the record high actually say about this market? The August 4 session showed that investors were still willing to pay up for growth, especially growth linked to AI. (fxstreet.com) The strongest gains were concentrated in technology and in companies with direct exposure to software, chips and computing demand, rather than spread evenly across all sectors. CNBC said the technology sector gained as Palantir’s jump helped power the Nasdaq to a much larger advance than the broader market. The August 6 setup was less straightforward. Futures flattened, oil remained a macro input, and the labor report became the next scheduled test for whether the rally could extend beyond the earnings burst that lifted stocks earlier in the week.
