U.S. equities delivered a classic seesaw performance on Tuesday.Apple briefly touched a $5 trillion market cap, Coca-Cola surged to a new all-time high post-earnings, and the Dow Jones Industrial Average edged close to its historical closing record with just one step remaining. Meanwhile, storage and optoelectronics stocks suffered for a second consecutive day, as the Philadelphia Semiconductor Index dropped over 4%, while SanDisk’s share price has fallen by half since July. The earnings season produced a series of contradictory results—Seagate and Corning both beat expectations, yet their stock prices were still crushed. In the Middle East, oil prices plunged during the day amid ceasefire rumors but violently rebounded after Iran struck a U.S. military base in Jordan.

Major Indices Mixed, Equal-Weighted Index Hits New High

S&P 500 rose 0.21%, closing at 7428.78. The Dow Jones Industrial Average gained 1.03% to 52747.32, just shy of its all-time closing high of 53055.91. The Nasdaq Composite declined 0.22% to 24876.91. Among S&P 500 constituents, 357 advanced and 145 declined; however, the equal-weighted index rose 1.14%, hitting a record high, indicating that this downturn was highly concentrated among a few major tech caps.

Among the Magnificent Seven, Google A climbed 2.19%—the best performer—Microsoft rose 1.09%, Nvidia edged up 0.25%, Amazon fell 0.23%, Meta dropped 0.08%, and Tesla declined 0.58%. Chinese-listed stocks maintained strength, with the Nasdaq Golden Dragon China Index rising 1.08%.

Apple Market Cap Breaks $5 Trillion, Defensive Stocks Rally

Apple reached $342.89 per share intraday, pushing its market capitalization above $5 trillion temporarily, finishing the day up approximately 1%. Coca-Cola surged 5% to a new all-time high, driven by strong Q2 results and an upward revision of full-year guidance. JPMorgan Chase and 3M also hit new all-time closing highs, while software stocks including Adobe and IBM advanced in tandem.

Storage and Optoelectronics Collapse, Philadelphia Semiconductor Index Falls for Two Days

Philadelphia Semiconductor Index dropped 4.49%, marking its second consecutive daily decline. The storage sector was hit hardest—Micron slid 8.85%, SK Hynix dropped 8.98%, SanDisk plunged 14.25%, and the stock has now lost half its value since July. The DRAM-focused ETF plunged 8.89% in a single session.

The optoelectronics sector fared no better—Corning declined over 12%, Coherent dropped more than 10%. Chip manufacturing and design firms weren’t spared either—Dell Technologies fell 8.15%, Intel sank 5.86%, AMD dropped 8.15%, and TSMC declined 1.7%.

This selloff stems from a confluence of three pressures. First, skepticism persists over whether AI-related capital expenditures will generate tangible returns. Second, Nvidia’s $750 billion circular financing arrangement is unsettling credit markets. Third, the accelerating pace of domestic Chinese memory chip development is reshaping investor sentiment. The recent listing buzz around ChangXin Memory Technologies on the A-share market has triggered a reassessment of China’s self-sufficiency trajectory in DRAM production, directly undermining the valuation logic of U.S.-based memory stocks. These three forces together have transmitted the sell-off from U.S. equities to the Asia-Pacific markets.

Seagate and Corning Deliver Stellar Results, Yet Stock Prices Disappoint

Seagate Technology reported fourth-quarter revenue and EPS significantly exceeding analyst estimates, with next quarter’s guidance far surpassing market expectations. Nevertheless, Seagate closed down 8.5%—only recovering over 10% in after-hours trading following the official release, lifting other storage stocks in turn.

Corning’s outcome was even more extreme. Despite Q2 revenue and profit beating forecasts and optical communications revenue growing 32% YoY, the company’s Q3 guidance implied a sharp deceleration in sequential growth—from 9% down to 3%–6%. Investors clearly wanted bigger surprises, resulting in Corning’s closing plunge of 12.1%.

NXP posted Q2 revenue and Q3 guidance above expectations, yet its stock still dropped over 4% after hours. Together, these earnings reports illustrate that current market pricing for semiconductor and storage companies has become exceptionally stringent—meeting or even exceeding expectations no longer serves as a safety cushion. The only catalyst capable of stabilizing stock prices is a clear signal of acceleration embedded in forward guidance.

This earnings test has only just begun. Storage, software, and MAG7 earnings will follow in the coming week. Their latest commentary on AI spending and output will directly determine whether the selloff spreading from the storage sector can finally find a bottom.

Ceasefire Rumors Push Oil Lower, Jordan Strike Sends Prices Rebounding

Oil markets experienced the largest single-day volatility in nearly three years. During the day, reports citing mediators in the Middle East indicated that the U.S. and Iran were nearing a revival of the June ceasefire agreement, sending WTI crude down over 5% to around $78, while Brent crude dropped over 6%, breaching $84.

COMEX Gold fell 1.11%, settling at $4090.40 per ounce. COMEX Silver dropped 2.5%, closing at $57.335 per ounce. Cryptocurrencies also weakened: Bitcoin opened at $63,706.66, down 2.5% from Monday, dipping intraday to $63,327.39; Ethereum opened at $1,890.67, down 3.2%, falling to $1,877.71 intraday.

Iran simultaneously set conditions for resuming maritime traffic through the Strait of Hormuz, demanding all vessels switch to Iranian-controlled waterways, abolishing the current international separation regime, and insisting only Iran conduct mine-clearance operations—far more rigid than previously speculated.

After U.S. equity markets closed, the situation reversed. Reports emerged that Iran had struck a U.S. military base in Jordan, triggering a 4.5% surge in WTI crude in after-hours trading, reclaiming much of the day’s losses. This dramatic intra-day shift between long and short positions underscores that market consensus on the conflict’s true trajectory remains speculative—any single piece of news can instantly reverse price direction.

Fed Decision in Focus: Can Williams Stick to His “No Guidance” Line?

The Federal Reserve will announce its interest rate decision during Wednesday’s U.S. trading session. Markets currently price in about a one-third chance of a hike, though some institutions offer starkly different views. The 10-year Treasury yield fell roughly 5 basis points to around 4.60%, while the 2-year yield dropped 5.17 bps to 4.2706%, and the U.S. Dollar Index dipped slightly by 0.03% to 101.49.

Frank Flight, macro strategy head at Citadel Securities, countered this view, arguing that the actual likelihood of a rate hike is being underestimated. He cited Williams’ need for a tangible action to demonstrate that fighting inflation is not merely rhetorical.

Williams’ approach of withholding forward guidance has already drawn internal criticism. Fellow Fed governor Lael Brainard, who once competed with Williams for the chairmanship, publicly stated she has never seen any theory proving that silence leads to smoother market functioning. The Wednesday decision and the ensuing press conference will thus serve as the first window to assess whether Williams alters his communication strategy.
