S&P 500 Sets New Record at 7,736, Dow Tops 54,000 - Palantir Soars 29%

Wall Street is on fire. The S&P 500 jumped 1.79% to close at a record 7,736.52 on Tuesday (4 August, US time), extending a 5-day winning streak powered by corporate earnings that blew past expectations and growing hopes of a peace agreement between the US and Iran.

That is not all. According to CNN Business, the Dow Jones Industrial Average also made history - surging 907 points (1.71%) to close above the 54,000 level for the first time ever, finishing at 54,084.99. The Nasdaq Composite rocketed 2.59% to 26,584.99.

This was the S&P 500's first record close in two months, surpassing the previous peak set in early June. If you are a Malaysian investor with exposure to US stocks, or simply tracking the direction of global markets, this is a development worth understanding properly. Let us break it down.

How the Three Major Indices Performed: All Sectors Green

Here is a summary of Tuesday's close, 4 August 2026 (US time):

• S&P 500: +1.79% to 7,736.52 (record high)
• Dow Jones: +907 points or +1.71% to 54,084.99 (first close above 54,000)
• Nasdaq Composite: +2.59% to 26,584.99
• Philadelphia Semiconductor Index: +6.55% to 12,179.26

What stands out is that all 11 sectors in the S&P 500 finished higher - a sign of broad-based buying rather than a rally propped up by a handful of mega-cap tech names. Information Technology led the charge with a gain of more than 4%, followed by industrials and financials.

The rally also builds on strong momentum from last week. Just two days earlier, we reported that the Dow Jones hit a record high with the Nasdaq jumping 2.13% - and the market clearly is not done yet.

Palantir Soars 29% - The Star of Earnings Season

The main driver of Tuesday's session was Palantir Technologies. Shares of the data and defence software company exploded 29.3% to $162.66 - its biggest single-day gain since February 2024 - after announcing extraordinary second-quarter results.

The numbers were genuinely striking. According to CBS News, CEO Alex Karp reported revenue growth of 93% year-on-year, with second-quarter revenue reaching $1.94 billion against analyst expectations of $1.8 billion. The company also raised its full-year 2026 revenue forecast - a signal of confidence that demand for its AI platform is nowhere near its peak.

We covered Palantir's results and other US market movers in our US stock news roundup for 4 August 2026 - worth a read for the full context leading into this record session.

Caterpillar, Marvell & SanDisk: Proof the AI Boom Is Spreading

Palantir was not the only star. Caterpillar - the heavy machinery maker often seen as a barometer of the global industrial economy - climbed 6.5% after reporting record quarterly sales exceeding $20 billion. The reason? The rapid buildout of AI data centers has fuelled strong demand for the company's power-generation and construction equipment.

Semiconductor and memory stocks also surged:

• Marvell Technology +12.81% to $218.59
• SanDisk +10.84%
• SK Hynix +8.17%

This is what makes the current phase of the AI boom interesting - it is no longer just an Nvidia story. AI infrastructure demand is now flowing to memory chip makers, construction equipment suppliers, even power generators. But not everything went up: Amazon slipped 2.32% and Meta Platforms eased 0.39% - a reminder that the market is still picking winners and losers.

US-Iran Peace Hopes: Oil Drops 5%

The rally's second catalyst came from geopolitics. Brent crude fell 4.9% to $79.64 a barrel after US Treasury Secretary Scott Bessent signalled that a deal to reopen the Strait of Hormuz was close.

"I think there is a chance we may have a deal today or tomorrow to open the Strait," Bessent said, as reported by CBS News. A Qatari official mediating the negotiations also confirmed that diplomatic efforts were actively continuing.

For context: since the US-Iran conflict erupted earlier this year, shipping access through the Persian Gulf has been uncertain, causing oil prices to swing wildly between $72 and $102 a barrel throughout July. That uncertainty has haunted markets for months - we covered its impact on Malaysians in our article on the 2026 Strait of Hormuz crisis.

It is also worth remembering that US markets sold off sharply when this conflict broke out in February. Since then, the indices have recovered step by step alongside diplomatic progress - and Tuesday's record close officially erased all of the conflict-era losses. For investors who stayed calm and did not panic-sell at the peak of the crisis, this is yet another proof of the power of discipline in long-term investing.

When oil prices fall, global energy and logistics costs decline, inflationary pressure eases, and the Federal Reserve gets more room to stay accommodative. That is the formula that injected confidence into Tuesday's session.

The Strongest Earnings Season Since 2021

Beneath the big headlines lies a more fundamental trend: corporate America is delivering an earnings season that is far better than expected. Analysts now project S&P 500 earnings-per-share (EPS) growth of around 50% - the largest jump since spring 2021, the post-pandemic recovery era.

Adam Crisafulli, head of research firm Vital Knowledge, summed up Tuesday's session simply: a combination of "blowout earnings" and positive remarks from Bessent on the potential Iran deal. According to Kitco News, this earnings strength could push markets even higher in the coming weeks - as long as there are no negative surprises from the Iran negotiations or economic data.

Other Corporate News Moving the Market

Beyond earnings, several major corporate developments coloured Tuesday's session and added fuel to the AI narrative:

• SpaceX jumped 9.43% - Elon Musk's company continues to attract attention following its public listing, with investors weighing the potential of the Starlink satellite business within the AI ecosystem.
• Anthropic and Volta announced a $10 billion computing agreement over a six-year term - further evidence that AI infrastructure spending shows no sign of slowing.
• Blackstone is reportedly pursuing a $36 billion debt financing package for Anthropic - a deal size that reflects just how capital-hungry the new generation of AI companies has become.
• Apple filed legal action seeking to bar OpenAI from using allegedly stolen trade secrets - a reminder that AI competition is now also being fought in the courtroom.
• Procter & Gamble is acquiring nutritional supplement brand Thorne for $3.8 billion - healthy merger and acquisition activity is a sign of corporate confidence.

Taken together, this news flow points to one thing: big capital is still pouring into the US economy, whether through AI infrastructure spending, debt financing or strategic acquisitions.

What Does This Mean for Malaysian Investors?

The most important question for you: how does this Wall Street rally affect a Malaysian investor's portfolio?

1. Positive sentiment for Bursa Malaysia

Wall Street records typically spill over into Asian markets the following day. Local technology and semiconductor stocks - many of which are plugged into the global AI supply chain - stand to benefit from the positive spillover. Foreign fund flows that have started returning to Bursa could also accelerate if global risk appetite stays elevated. For unit trust holders and EPF members, Wall Street's performance matters indirectly too, since many of these funds carry international equity exposure.

2. Falling oil: a double-edged sword for Malaysia

As a petroleum exporter, lower oil prices are less favourable for Petronas and oil and gas counters on Bursa. At the same time, cheaper oil reduces global inflationary pressure and import costs - positive for the ringgit and consumer sectors.

3. An opportunity for US market exposure

This rally is a reminder of why diversifying into the US market has become increasingly popular among Malaysian investors. If you are just getting started, read our guide on the 7 things Malaysian investors must know before investing in US stocks to avoid the common beginner mistakes.

Risks: Do Not Get Carried Away

Before you rush into the market, keep a few things in mind:

The Iran deal is not done. Bessent's remarks reflect hope, not confirmation. Geopolitical negotiations can collapse at the last minute - and if that happens, oil prices could spike again and this rally could reverse quickly. We saw the same pattern in June when US-Iran peace news sent oil tumbling and tech stocks soaring - before tensions flared up again.

Valuations are getting stretched. After a 5-day rally and fresh records, some AI names are trading at premium valuations. Palantir, for instance, is now among the most "expensive" stocks in the S&P 500 on a price-to-sales basis. High expectations mean plenty of room for disappointment.

Markets move fast. Sessions following record highs often see profit-taking activity. Indeed, in Wednesday's trading the indices were seen catching their breath after Tuesday's big surge. Do not make investment decisions purely out of FOMO from seeing record-high headlines.

What Is Next: 3 Things to Watch

First, the outcome of the Iran negotiations. Bessent said a deal could come "today or tomorrow" - which means within days we will know whether the Strait of Hormuz genuinely reopens. If it does, oil may weaken further and the rally could continue. If talks fail, brace for volatility.

Second, the rest of earnings season. Hundreds of S&P 500 companies have yet to report second-quarter results. Any major surprise - positive or negative - from a heavyweight name could change the market's direction in an instant.

Third, the Federal Reserve's response. Falling oil prices ease inflationary pressure, and markets now expect the Fed to have more room to stay accommodative. Upcoming US inflation and jobs data will determine whether that expectation is realistic.

Frequently Asked Questions (FAQ)

Why did the S&P 500 hit a record high on 4 August 2026?

Two main catalysts: corporate earnings that far exceeded expectations (especially Palantir and Caterpillar) and hopes of a US-Iran agreement to reopen the Strait of Hormuz, which sent oil prices down nearly 5%.

What were the record closing levels for the S&P 500 and Dow Jones?

The S&P 500 closed at 7,736.52 (+1.79%) while the Dow Jones closed at 54,084.99 (+1.71%) - the first time the Dow has ever closed above the 54,000 level.

Why did Palantir stock jump 29% in one day?

Palantir reported 93% year-on-year revenue growth with second-quarter revenue of $1.94 billion, beating expectations of $1.8 billion, and raised its full-year 2026 forecast. It was the stock's biggest single-day gain since February 2024.

What does the Strait of Hormuz have to do with the stock market?

The Strait of Hormuz carries roughly one-fifth of the world's oil supply. Shipping uncertainty since the US-Iran conflict caused oil to swing between $72 and $102 a barrel. Hopes of the strait reopening pushed oil prices down, easing inflation pressure and lifting investor risk appetite.

Will this Wall Street rally affect Bursa Malaysia?

Generally yes - positive Wall Street sentiment typically spills over into Asian markets, especially the technology and semiconductor sectors. However, falling oil prices could weigh on local oil and gas counters.

Is now a good time to buy US stocks?

No one can guarantee short-term market direction. After a 5-day rally, some stocks are trading at high valuations and profit-taking risk is real. The safest approach is to invest gradually according to your financial plan, not to chase news-driven momentum.

How can Malaysian investors buy US stocks like Palantir?

You need a CDS account and a trading account with a Malaysian broker that offers global market access such as M+ Global. Once your account is approved, you can buy stocks listed on the NYSE and NASDAQ directly in USD.

Conclusion

The S&P 500's record at 7,736 and the Dow's break above 54,000 reflect two powerful forces: the strongest earnings season since 2021 driven by AI infrastructure spending, and geopolitical relief as a US-Iran agreement draws closer. But a fast rally also brings stretched valuations and the risk of a pullback if the Iran talks collapse. Smart investors will seize the opportunity with caution, not FOMO.
