AI Earnings Concerns Drive Tech-Led Selloff Into Weekend | Daily Market Brief - October 31, 2026

Research created at 11:17 AM ET · Full analysis

1. EXECUTIVE SUMMARY

• AI EARNINGS CONCERNS DEFINE THE WEEKEND SETUP. The S&P 500 closed Friday at 7,580.07, down 1.82%, while the Nasdaq Composite fell 2.86% to 25,437.00. Weekly losses were 0.6% and 2%, respectively, as investors questioned the returns on technology infrastructure spending. [1][49][54]

• THE SELLOFF WAS BROAD, BUT CONCENTRATED IN TECHNOLOGY. The Nasdaq-100 lost 3.46% Friday versus a 1.09% decline for the Dow. Intel fell 28.58%, reinforcing semiconductor-sector concerns; the Nasdaq Composite finished its third consecutive losing week. [1][49][52]

• TREASURIES PROVIDED SOME PROTECTION; GOLD DID NOT. The IEF Treasury ETF gained 0.52% Friday, while the GLD gold ETF fell 3.47%. Official October 30 Treasury yields closed at 4.56% for two years, 4.94% for ten years and 5.31% for thirty years, leaving long-term financing costs an important constraint on equity valuations. [2][3]

• SATURDAY’S IRAN DIPLOMACY CREATES TWO-WAY ENERGY RISK. Qatari mediators are attempting to restart U.S.–Iran negotiations, according to CNBC, while Reuters reported an Iranian official’s allegation of a U.S. attack near Qeshm Island. Neither development establishes a durable easing of tensions. [41][42]

• CRYPTO HAS AN ADDITIONAL OPERATIONAL SHOCK. CNBC’s Saturday update estimates the October 29 Binance hack’s impact at $6.3 billion, with about $3 billion of stolen assets frozen. Friday’s Bitcoin and Ether ETFs fell 4.44% and 3.98%, respectively, combining broad risk aversion with exchange-security concerns. [21][2]

• NEXT WEEK TESTS BOTH EARNINGS AND POLICY CONFIDENCE. Apple and Palantir are scheduled Monday, AMD Tuesday and Qualcomm Wednesday; Tuesday’s midterm elections and Friday’s employment report add major event risk. U.S. equity futures reopen Sunday at 6:00 PM ET. [10][13][14][9][8][4]

3. TODAY'S MAIN MARKET NARRATIVE

THE MARKET IS REASSESSING THE ECONOMICS OF AI, NOT SIMPLY REACTING TO HIGHER INTEREST RATES. Friday’s S&P 500 and Nasdaq Composite declines were their worst since June. The Nasdaq ended 7.8% below its October record and recorded its weakest month since March 2025; the S&P 500 finished roughly 3% below its peak. That divergence suggests investors are applying a larger valuation discount to technology’s expected future earnings than to the broader corporate sector. [52]

Saturday’s reporting adds context to the selloff: Microsoft, Alphabet and Amazon delivered capital-expenditure figures or forecasts below analysts’ expectations during the week. Lower spending can support cash flow at the buyers of infrastructure, but it can also weaken revenue expectations for chipmakers and other suppliers. The simultaneous concern about excessive spending and disappointing spending commitments reflects uncertainty about both AI demand and investment returns. [49]

The cross-asset tone is risk-off, but not a uniform flight to safety. Treasury ETFs rose, while gold, silver and crypto ETFs declined; the dollar slipped slightly. These moves suggest investors differentiated between assets rather than treating every perceived hedge as interchangeable. [1][2]

The constructive scenario is that earnings clarify AI monetization, defensive leadership persists and Iran diplomacy reduces energy risk. Its signposts would be stabilization in technology, less volatility and continued resilience outside the largest growth names. The adverse scenario is that weaker technology expectations coincide with renewed energy disruption, leaving equities exposed to both slower earnings growth and inflation-sensitive interest rates.

Next week’s earnings, labor data and diplomatic developments will help distinguish those paths. [42][49][54]

4. U.S. EQUITY MARKET OVERVIEW

Friday’s declines across the S&P 500, Dow and Russell 2000 show that selling was broader than a handful of technology stocks. Nevertheless, the Nasdaq-100’s 3.46% loss, against the Dow’s 1.09% decline, identifies large growth companies as the center of pressure. Small caps fell 1.66%, providing little evidence of an immediate rotation into more economically sensitive equities. [1]

For the week, the S&P 500 fell 0.6%, the Nasdaq Composite 2% and the Dow 0.9%. The Nasdaq’s third straight weekly decline makes Friday more significant than an isolated earnings-day shock: confidence in the previous leadership has been weakening over several weeks. [54][49]

There is still an important distinction between index concentration risk and broad market deterioration. October’s S&P 500 Equal Weight gain of roughly 5%, alongside an almost 7% monthly Nasdaq-100 decline, indicates substantial performance outside mega-cap growth. Consumer staples rose 11.4% over the month, ranking behind only energy. That is evidence of rotation over the month, although it did not prevent Friday’s broad losses. [53]

Friday’s S&P 500 close of 7,580.07 and Nasdaq Composite close of 25,437.00 are useful reopening reference points—not established technical support. A rebound confined to a few mega-cap names would offer less reassurance than improvement across both the growth benchmarks and the broader market. [1]

5. MAJOR COMPANY HEADLINES

Intel (INTC)

Intel fell 28.58% Friday, its worst session since 1974, becoming the clearest company-specific expression of the semiconductor selloff. Saturday coverage linked the sector’s weakness to Intel’s disappointing outlook, with Nvidia also trading lower. The broader implication is that investors are questioning whether chip demand can support valuations across the supply chain, rather than treating every AI-related business as a uniform growth exposure. [52][49]

Microsoft (MSFT), Alphabet (GOOGL) and Amazon (AMZN)

Saturday’s CNBC review reported that all three companies delivered capital-spending figures or forecasts below analyst expectations during the week. This creates a two-sided earnings debate: spending discipline may improve future cash generation, but a slower infrastructure buildout can constrain growth expectations for suppliers. Their next disclosures on utilization, customer demand and monetization matter more than spending totals alone. [49]

Berkshire Hathaway (BRK.A / BRK.B)

Berkshire’s Class A shares ended the week at $815,600, up 0.3% for the week, contrasting with losses in the major U.S. indices. That relative resilience is consistent with investors seeking earnings exposure outside the technology investment cycle, though it should not be read as evidence that all value-oriented shares are insulated from broader selling. [39][54]

6. BANKS, CREDIT, AND FINANCIAL CONDITIONS

Friday’s credit ETF performance was restrained relative to equities: high-yield HYG fell 0.19%, while investment-grade LQD rose 0.05%. Those price moves do not establish a credit-spread trend, but they suggest the equity selloff had not translated into comparable declines across corporate-bond ETFs. [4]

The more consequential medium-term link is AI’s financing requirement. Friday evening reporting cited Goldman Sachs estimates that roughly one-third of this year’s Big Tech capital spending would be debt-financed, including approximately $250 billion of hyperscaler bond issuance. That creates a channel through which doubts about AI returns could affect financing costs and credit selection, especially alongside competing Treasury supply. [60]

Financial conditions therefore look differentiated: Treasury prices offered some relief Friday, while weaker equities and large prospective funding needs argue against describing the overall backdrop as broadly easing. [2][60]

7. RATES, BONDS, T-BILLS, AND FED POLICY

At the official close of October 30, Treasury par yields were 4.56% for two years, 4.94% for ten years and 5.31% for thirty years. The ten-year yield exceeded the two-year by 38 basis points, giving the curve a positive slope. Three-month bills yielded 4.16%. [3]

Treasury ETF prices rose Friday: SHY gained 0.23%, IEF 0.52% and TLT 0.20%. That is consistent with demand for government bonds during the equity decline, although ETF returns should not be converted into precise changes in benchmark yields. The intermediate-maturity ETF’s stronger performance also cautions against treating the move as a uniform rally across the curve. [2]

The positive curve alone does not resolve whether investors are pricing stronger growth, persistent inflation or additional compensation for holding longer maturities. For equities, the practical constraint is that a 4.94% ten-year yield still places substantial weight on the timing and certainty of future cash flows. [3]

Next week’s manufacturing prices, productivity and labor-market releases will help frame that trade-off. A softer employment picture could support bonds, but energy-driven price pressure could limit the relief. Scheduled Fed remarks throughout the week provide additional opportunities to assess how policymakers balance those risks. [8][9][15]

8. ECONOMIC DATA AND MACRO INDICATORS

THE COMING WEEK’S CENTRAL MACRO QUESTION IS WHETHER LABOR DEMAND IS COOLING WITHOUT A SHARPER LOSS OF ACTIVITY. Tuesday’s September JOLTS report carries a consensus of 7.10 million openings versus 7.079 million previously. Friday’s October employment report then provides the broader labor-market assessment. [45][8]

Monday’s ISM manufacturing consensus is 54.7 against 54.5 previously, implying expectations for continued expansion. The prices-paid component’s prior reading of 77.9 makes its direction particularly relevant: resilient output alongside persistent input-cost pressure would offer less interest-rate relief than growth alone might suggest. [45][9]

Thursday’s preliminary third-quarter productivity and costs report provides a separate test of whether output gains are offsetting wage pressure. Read together with jobless claims and payrolls, it can help distinguish a sustainable expansion from one that keeps inflation pressure elevated. [8]

9. COMMODITIES AND ENERGY

Oil-linked ETFs held up Friday: USO gained 0.38% to $168.83, while Brent-linked BNO gained 0.89% to $71.39. Saturday’s competing diplomatic and security developments leave energy exposed to headline-driven repricing when trading resumes. Progress toward negotiations could reduce the geopolitical premium; renewed attacks could reverse that process. [2][41][42]

Russia also extended its general ban on diesel exports by producers through January, while allowing some volumes to continue reaching international markets. This matters separately from crude supply because restrictions on refined products can affect transport and industrial fuel costs even without an equivalent move in crude benchmarks. [40]

Precious metals offered no protection Friday: GLD fell 3.47% and SLV fell 5.67%, while copper-linked CPER declined 1.86%. These returns show the limits of assuming that geopolitical uncertainty automatically supports gold or that all commodities move with oil. [2]

10. CRYPTOCURRENCY AND DIGITAL ASSETS

CNBC’s 10:26 AM ET Saturday update estimated the Binance hack’s impact at $6.3 billion, with approximately $3 billion of stolen assets frozen. The incident occurred October 29, but recovery and access to funds remain the current market issue. Frozen assets should not be equated with completed reimbursement. [21]

An overnight account described a target for phased withdrawals early Sunday. Execution matters more than the announced timetable: functioning withdrawals would help reduce operational uncertainty, while delays could sustain concerns about liquidity and custody. [4]

Friday’s IBIT decline of 4.44% and ETHA decline of 3.98% aligned with the broader risk-off move, but crypto also faces this distinct exchange-security shock. Those ETF closes describe Friday’s U.S. session, not Saturday spot trading. [2][21]

11. FOREIGN EXCHANGE

The U.S. Dollar Index closed Friday at 101.96, down 0.07%. Its modest decline alongside sharply weaker equities suggests Friday was not a straightforward flight into dollar assets. [1]

For the coming week, the dollar’s response to U.S. labor data matters for both financial conditions and the international earnings translation of multinational companies. A dollar rebound alongside firm yields would add pressure to global risk assets; continued dollar softness could offset part of that pressure. These are conditional cross-asset channels, not conclusions established by Friday’s small move.

12. GLOBAL MARKETS AND GEOPOLITICAL RISK

IRAN IS THE PRINCIPAL WEEKEND GEOPOLITICAL RISK FOR U.S. INVESTORS. CNBC reported Saturday that Qatari mediators held more than twelve hours of talks in Tehran on Friday aimed at restarting direct U.S.–Iran negotiations, with further talks expected in Doha. Iran also warned of a geographically unrestricted response to new U.S. attacks. This creates a meaningful distinction between diplomatic engagement and an actual agreement that reduces supply or shipping risk. [42]

Reuters separately reported an Iranian official’s allegation that the United States attacked fishing boats near Qeshm Island. The claim raises escalation risk, but it remains an attributed allegation rather than an independently established account of the incident. [41]

Tuesday’s U.S. midterm elections add domestic policy uncertainty to the same week’s earnings and macro catalysts. The direct investor questions concern the resulting balance of legislative power and its implications for fiscal policy and regulation. Crypto-linked organizations have contributed more than $200 million during this election cycle, underscoring the sector’s sensitivity to the regulatory outcome. [9][33]

• SUNDAY’S 6:00 PM ET FUTURES REOPENING: The first U.S. equity-futures response to weekend diplomacy and crypto developments will show whether Friday’s risk aversion persists. [4]
• S&P 500 AT 7,580.07 AND NASDAQ COMPOSITE AT 25,437.00: Friday’s closes provide reference points for stabilization; participation beyond mega-cap technology would make any recovery more persuasive. [1]
• VIX AT 19.42: A further rise would suggest investors are demanding more protection through earnings, elections and payrolls. [1]

• TEN-YEAR TREASURY YIELD AT THE OCTOBER 30 CLOSE OF 4.94%: Whether bonds continue cushioning equity weakness matters for the broader financing backdrop. [3]
• APPLE, PALANTIR, AMD AND QUALCOMM EARNINGS: Demand visibility and conversion of AI spending into revenue and cash flow are the central questions. [10][13][14]
• TUESDAY’S JOLTS AND FRIDAY’S PAYROLLS: The key distinction is gradual cooling versus labor weakness large enough to challenge earnings expectations. [8][45]

• IRAN NEGOTIATIONS AND ENERGY-MARKET REOPENING: Diplomatic progress could reduce inflation risk, while renewed escalation could complicate the bond market’s defensive role. [41][42]
• BINANCE WITHDRAWALS AND ASSET RECOVERY: Operational progress would help distinguish a contained exchange incident from a more persistent crypto-liquidity problem. [4][21]
• TUESDAY’S ELECTION RESULTS: Changes in legislative control could reshape fiscal and sector-specific regulatory expectations. [9][33]

15. ANALYST TAKEAWAY

THE DOMINANT ISSUE IS THE CREDIBILITY OF FUTURE TECHNOLOGY CASH FLOWS. Friday’s market action extended a multiweek reassessment of AI leadership, while October’s stronger equal-weight and defensive performance showed that weakness in the largest growth stocks is not synonymous with weakness everywhere. [49][52][53]

The setup is risk-off in equities, but mixed across assets. Treasury ETFs absorbed some defensive demand; gold and crypto did not. The biggest risk investors may underestimate is the combination of disappointing technology returns and renewed energy inflation—an outcome that could pressure earnings while limiting relief from lower discount rates. [2][42][60]

The constructive possibility is a broader earnings-led market in which nontechnology resilience persists and AI companies provide clearer evidence of monetization. Next week’s earnings, employment data and diplomatic developments will determine whether Friday marks another stage of orderly rotation or a widening loss of confidence.
