Dow Jones Hits New Record High Above 54,400 as Earnings Season and Iran Deal Hopes Continue

NEW YORK — The Dow Jones Industrial Average traded at a fresh record high Thursday morning, changing hands at 54,488.23, up roughly 0.20%, as the blue-chip index extended a remarkable win streak even as a busy stretch of corporate earnings produced sharply divergent reactions across individual stocks and sectors.

Thursday's gain built on Wednesday's session, when the Dow closed at a record high for a fifth straight positive session, even as the S&P 500 and Nasdaq Composite both finished lower, weighed down by weakness in technology shares following the prior day's rally to record levels. Kyle Rodda, senior financial market analyst at Capital.com, described Wednesday's pullback in tech shares as reflecting a lack of fresh catalysts for the market to work with, leading some investors to lock in profits following the sharp gains of recent sessions.

A Market Driven by Iran Diplomacy and Corporate Earnings

Much of this week's overall market momentum has continued to track developments in ongoing talks aimed at reopening the Strait of Hormuz to commercial shipping. Rodda noted that a breakthrough in U.S.-Iran negotiations could provide the next catalyst for markets, with reports suggesting an agreement may be close at hand. That optimism has helped support broader risk appetite even as individual sectors have shown notable divergence in their reaction to the latest round of corporate earnings.

Thursday's trading session arrived amid a particularly dense stretch of earnings reports, prospects for an imminent Hormuz deal, and freshly released labor market data, all of which investors were working to digest in early trading. Futures on the Dow rose 0.2% ahead of the opening bell, extending the index's record-setting run, while S&P 500 futures ticked up a more modest 0.1% and Nasdaq-100 futures slipped 0.6%, reflecting continued softness concentrated specifically in technology and semiconductor shares.

Chip and Memory Stocks Under Pressure

The divergence between the Dow's continued strength and weakness elsewhere in the market was driven largely by a sharp selloff in memory chip and storage companies following earnings releases from SanDisk and Western Digital late Wednesday. Both companies posted quarterly results that beat expectations but issued forward guidance that fell short of Wall Street's elevated forecasts, triggering steep declines in their shares. SanDisk shares were down more than 13% in early Thursday trading, while AMD, which had also reported earnings this week, fell more than 2%. A broader gauge of chipmaker stocks fell 1.4% in overnight trading, even as Nvidia shares managed to climb against that broader sector weakness.

Investors have remained intensely focused on questions surrounding artificial intelligence capital spending and monetization throughout this earnings season, a dynamic that analysts say has contributed to unusually punishing stock reactions whenever a high-profile AI-linked company's results or guidance fall even modestly short of expectations, regardless of how strong the underlying quarterly performance may otherwise be.

SpaceX Faces a Major Test

Among the companies facing particular scrutiny Thursday was SpaceX, whose stock tumbled 14% Wednesday despite reporting strong second-quarter earnings, as roughly $101 billion worth of shares became eligible for trading following the expiration of a post-IPO lockup period. SpaceX shares remained near their all-time lows heading into Thursday's session, as investors weighed the potential for a wave of new selling pressure tied to the lockup expiration against the company's underlying revenue growth and continued heavy investment in artificial intelligence infrastructure.

A Warning From Wall Street's Biggest Bank

Amid the market's continued run to record territory, JPMorgan Chief Executive Jamie Dimon offered a note of caution this week, warning that leverage across financial markets remains historically elevated. In an interview with CNBC, Dimon said margin debt, the amount investors borrow against their portfolios to purchase additional securities, is currently the highest it has ever been, and cautioned that such hidden borrowing could amplify the impact of any future market disruption. Dimon's comments add to a broader set of concerns some strategists have raised about the sustainability of markets' rapid climb to record levels in recent weeks, even as the underlying macro backdrop, including cooling oil prices and continued corporate earnings strength, has remained broadly supportive.

A Strong Start to the Week

Thursday's record extends a pattern that has held for much of the past week. The Dow closed at an all-time high Monday, settling at 53,178.41 after advancing 693.38 points, or 1.32%, in a session driven by broad market strength following President Donald Trump's decision to call off planned strikes against Iran, a move that sent oil prices sharply lower. That rally continued into Tuesday, when the Dow surged a further 907.47 points, or 1.71%, to close at 54,085.88, alongside similarly strong gains for the S&P 500 and Nasdaq Composite, with the latter boosted in part by a 29% rally in Palantir Technologies shares. Monday's session also saw Amazon briefly surpass a $3 trillion market capitalization for the first time, before the stock pulled back roughly 2% Tuesday after founder Jeff Bezos filed to sell approximately $4 billion worth of shares.

Global Markets React to the Same Currents

The themes driving U.S. markets this week have echoed across global exchanges as well. Asia-Pacific markets broadly rose Wednesday, with South Korea's KOSPI climbing 3.8% to close at 6,598.26 amid strong regional risk appetite, though sentiment shifted considerably by Thursday, when memory chip weakness tied to the SanDisk and Western Digital guidance miss triggered a sharp reversal across South Korean and Japanese technology shares specifically.

With Thursday's session continuing to balance the Dow's steady climb to new records against pronounced weakness in technology and chip-related names, investors are likely to remain focused on two parallel storylines in the days ahead: further developments in the effort to finalize a deal reopening the Strait of Hormuz, and the continued flow of corporate earnings reports, which have produced some of the most divergent stock reactions of the year so far, rewarding companies that clear elevated expectations while punishing even modest guidance shortfalls among high-profile AI and technology names.
