S&P 500 Holds Near Highs Ahead of Heavy Earnings Slate

During the prior session on Wednesday, October 21, the S&P 500 posted +0.5%, leaving the market -0.8% from its peak, while SPY closed at $773.09. The Nasdaq 100 logged +1.1%, the Dow recorded +0.6%, and the Russell 2000 small caps finished +0.3%. Across the top 1,000 U.S. companies, 56.6% finished higher, reflecting broad-based participation across large-capitalization shares heading into the new trading session.

While New York was shut, EasyAlpha re-graded covered companies across the market. Our own assessment moved higher on Marvell Technology Group Ltd (MRVL) E to C on its price behaviour, Advanced Micro Devices Inc (AMD) D to C on its price behaviour, and CME Group Inc (CME) D to C on its fundamentals. These adjustments reflect our own measurements moving up, indicating that each company improved relative to its previous standing.

At the same time, our view moved lower on Carrier Global Corp (CARR) C to E on the sentiment around it, Moodys Corporation (MCO) C to D, and Teledyne Technologies Incorporated (TDY) B to C on its price behaviour. As with the upgrades, these downward revisions stem entirely from our own analytical measurements rather than corporate press releases or Street commentary, with each name slipping relative to its earlier evaluation.

In round-the-clock trading as of 10:05 am New York, benchmark commodities saw silver -2.0% and gold -1.2%. In foreign exchange, trading showed the yen against the dollar +0.9% alongside the euro against the dollar -0.1%. These moves established the international backdrop for this morning's opening bell while U.S. equity exchanges remained closed.

Corporate earnings will dominate market attention throughout Thursday, October 22, with 114 covered companies scheduled to release quarterly results. Today marks an acceleration in the quarterly reporting cycle, as 804 covered companies are set to report over the coming week. Before the opening bell, corporate reports feature Procter & Gamble Company (PG, graded C), Union Pacific Corporation (UNP, graded C), Blackstone Group Inc (BX, graded C). Following the close of regular trading, scheduled releases include Western Digital Corporation (WDC, graded D).

Several individual stocks warrant attention heading into today's session based on fresh developments. In the semiconductor space, Advanced Micro Devices Inc (AMD) drew attention heading into the open, with our sources showing no confirmed driver from major financial wires. In capital equipment, Lam Research Corp (LRCX) remains in focus following the release of its quarterly earnings call transcript. Meanwhile, Marvell Technology Group Ltd (MRVL) warrants close tracking as its price behavior shifted during recent sessions without a verified corporate announcement.

Carrying over from Wednesday, October 21, several large single-stock moves established significant price discovery heading into the morning open. On the upside, notable strength appeared in Skydance Corporation (SKYD) +10.8% and Super Micro Computer Inc (SMCI) +9.5%. Skydance surged following public comments outlining a potential $8 billion to $10 billion equity investment by SpaceX that could help reduce the entertainment group's debt load. Super Micro Computer climbed after issuing preliminary first-quarter revenue guidance between $18.5 billion and $19.5 billion, well above previous projections on surging artificial intelligence infrastructure orders.

Conversely, downside pressure from the previous session remains relevant as trading resumes, highlighted by AT&T Inc. (T) -6.4% and DexCom Inc (DXCM) -6.4%. AT&T fell after quarterly results revealed slower postpaid phone additions, a non-cash impairment charge, and balance-sheet disclosures showing net debt of $149.8 billion, pushing its leverage reduction target out to 2029. Meanwhile, our sources show no reported corporate driver for the decline in DexCom, leaving the retreat as a move in the trading tape itself.

Understanding why overnight currency movements matter to someone who holds only U.S. shares is a vital concept for navigating market sessions. An investor whose portfolio consists entirely of domestic companies might assume that foreign exchange rates are irrelevant to their daily returns. Yet major American corporations, particularly those in the S&P 500, operate globally and generate substantial revenue outside the United States. When foreign currencies shift against the U.S. dollar, that movement flows directly into corporate earnings through two main channels: currency translation and export competitiveness. In financial accounting, overseas sales must eventually be translated back into U.S. dollars for consolidated quarterly reports. When foreign currencies weaken relative to the dollar, those international earnings convert into fewer domestic dollars, acting as an automatic headwind to reported revenue and profit margins. Conversely, when foreign currencies strengthen, as the yen did overnight, every unit of overseas business translates into more U.S. dollars, giving domestic multinationals an organic financial boost. Beyond accounting, exchange rates influence the real-world purchasing power of international buyers. A stronger dollar makes American software, industrial machinery, and consumer products more expensive for foreign customers, potentially dampening international order volumes. A softer dollar makes American exports cheaper and more competitive abroad. Consequently, holding domestic equities inherently involves currency exposure, meaning overnight foreign exchange movements frequently shape the performance of household American companies before the opening bell.
