Dow Gains as AI Financing Fears Push Nasdaq Lower and Treasury Yields Below 5%

Mumbai, Oct 24: US stock markets ended the week of 19–23 October with sharply divergent performances as concerns over artificial intelligence (AI) financing triggered a rotation away from technology shares and towards more defensive investments. The Dow Jones Industrial Average gained approximately 0.7% for the week, while the S&P 500 declined around 0.2% and the Nasdaq Composite fell roughly 0.5%.

The key catalyst was growing concern over the cost of financing AI infrastructure. Rising credit spreads on data-centre borrowers and a reported surge in capital expenditure at a major technology company intensified questions about whether the sector’s investment boom could be sustained without putting pressure on cash flows and borrowing costs.

Thursday, 22 October, proved decisive. The Nasdaq plunged 2.60%, while the S&P 500 fell 1.21%. At the same time, investors moved into US government bonds, pushing the 10-year Treasury yield down 19.40 basis points to 4.952%. The decline below 5% highlighted the growing influence of economic and credit concerns, even as rising oil prices continued to threaten the inflation outlook.

By Friday, technology stocks had stabilised, but the week’s losses underscored an important shift: investors were becoming more selective about AI-related investments, while energy, smaller companies and defensive sectors showed greater resilience.

Nasdaq Plunges 2.60% on Thursday as AI Financing Fears Trigger a Bond Rally

US equities began the week with mixed trading as investors assessed corporate results, geopolitical developments and the outlook for interest rates.

On Monday, the Dow slipped 0.07% to 51,966.03, while the S&P 500 gained 0.41% to 7,690.73 and the Nasdaq rose 1.11% to 26,430.89. Energy stocks benefited from higher crude prices, while technology shares attempted to recover from earlier losses. The 10-year Treasury yield remained near 5.07%.

On Tuesday, the Dow advanced 1.02% to 52,495.88 and the S&P 500 gained 0.28% to 7,712.57. The Nasdaq was nearly unchanged at 26,424.82 as financial and industrial stocks attracted buyers while semiconductor shares lagged. Brent crude approached $110 a barrel amid concerns about supply disruptions.

Wednesday brought further gains for the Dow and S&P 500, which rose 0.69% and 0.58%, respectively. The Nasdaq advanced 1.05% to 26,702.86. However, widening credit spreads on AI-related borrowers indicated that financing concerns were building beneath the surface. The 10-year Treasury yield reached approximately 5.11%.

Thursday delivered the week’s sharpest reversal. The Nasdaq plunged 2.60% to 26,008.86, while the S&P 500 dropped 1.21% to 7,663.43. The Dow slipped just 0.02%. A reported 80% year-over-year increase in capital expenditure at a major technology company, alongside concerns about data-centre debt, intensified fears about the sustainability of AI investment.

Government bonds rallied sharply. The two-year Treasury yield fell 18.50 basis points to 4.638%, the 10-year yield dropped 19.40 basis points to 4.952%, and the 30-year yield declined 15 basis points to 5.287%.

On Friday, the Dow fell 1.18% to 52,241.55, the S&P 500 declined 0.43% to 7,629.92, and the Nasdaq slipped 0.08% to 25,986.95. Technology shares recovered modestly, but the broader market remained under pressure. Brent crude stayed above $112 a barrel, gold traded near $4,025 an ounce and the US Dollar Index recovered to 101.75.

Dow Holds Up Better Than Technology Stocks as Defensive Shares Support Performance

The Dow Jones Industrial Average closed Friday at 52,241.55, compared with the previous week’s close of 52,002.41. Its relative resilience reflected its different sector composition and lower direct exposure to semiconductor stocks than the Nasdaq.

Financials, healthcare and consumer staples helped cushion the impact of the technology selloff. Energy companies also benefited from rising oil prices, while the rotation towards value-oriented businesses supported selected industrial and financial stocks.

However, the Dow’s relative strength should not be interpreted as evidence of uniformly improving market conditions. Its performance instead demonstrated how differences in sector exposure can produce sharply contrasting results across major indices during periods of concentrated selling.

S&P 500 Slips as Technology Weakness Offsets Gains Across Eight Sectors

The S&P 500 closed at 7,629.92, below its previous weekly close of 7,659.44. Its weekly high was 7,757.17 on Wednesday, before Thursday’s technology-led selloff erased much of the earlier advance.

Eight of the index’s 11 sectors reportedly recorded weekly gains, but weakness in information technology and communication services weighed heavily on the benchmark. Energy, financials and consumer staples provided support, although these gains were insufficient to offset losses among major growth companies.

The divergence highlights the limitations of relying exclusively on headline index performance. Because the S&P 500 is weighted by market capitalisation, large technology companies have a disproportionate influence on its direction. A concentrated decline among these companies can therefore pull the overall index lower even when several other sectors are performing well.

Nasdaq Falls 0.5% as AI Spending Concerns Override the Benefit of Lower Yields

The Nasdaq Composite ended the week at 25,986.95, compared with 26,140.03 the previous week. It reached 26,702.86 on Wednesday before Thursday’s sharp reversal pushed it lower.

The selling centred on technology and semiconductor companies exposed to changing expectations for AI infrastructure spending. Investors questioned whether the enormous capital commitments required to build data centres and computing capacity would translate into sufficient future revenue and free cash flow.

Falling Treasury yields would normally support growth stocks because they reduce the discount rate applied to expected future earnings. This time, however, yields declined amid concerns about economic growth and credit risk.

Consequently, the bond rally did not provide the expected relief to technology valuations. Instead, investors remained focused on financing costs, cash generation and the possibility that AI investment could prove more difficult to sustain than previously anticipated.

Russell 2000 Gains 2.1% as Small Caps Break a Six-Week Losing Streak

The Russell 2000 rose approximately 2.1% to close near 2,784, according to MarketWatch, ending a six-week losing streak described as the longest since 2018.

Small-cap stocks benefited from their lower exposure to mega-cap technology companies and their greater representation in domestically focused industries. Financial and industrial businesses attracted interest as investors moved away from expensive growth stocks.

Employment data also influenced expectations. The September payrolls report showed that the US economy added just 29,000 jobs, well below forecasts of approximately 84,000–90,000. The weaker figure strengthened expectations that the Federal Reserve would leave interest rates unchanged at its October meeting.

A pause in rate increases and lower Treasury yields can ease pressure on smaller companies, many of which are more sensitive to financing costs. Nevertheless, the Russell 2000’s weekly advance does not eliminate the risks associated with weaker employment or tighter credit conditions.

Semiconductor Index Suffers a 6.72% Decline as AI Investment Risks Intensify

The Philadelphia Semiconductor Index (SOX) experienced significant selling pressure, falling as much as 6.72% during the week, according to Bolsamania. Its decline from June highs exceeded 26%, placing the index in bear-market territory.

The selloff reflected growing uncertainty about the pace and profitability of AI-related investment. Semiconductor manufacturers and suppliers stand to benefit from increased demand for AI computing, but their valuations depend partly on expectations that customers will continue expanding infrastructure spending.

Widening credit spreads on data-centre borrowers raised concerns about the ability of customers to finance additional investment. If financing becomes more expensive, some projects could be delayed or scaled back, potentially affecting demand across the semiconductor supply chain.

Although falling Treasury yields would ordinarily support high-growth stocks, the yields declined because of risk aversion. This left semiconductor shares vulnerable to concerns about spending sustainability and credit quality.

Smaller Companies Show Greater Resilience as Mega-Cap Selling Narrows Market Breadth

The S&P MidCap 400 and S&P SmallCap 600 appeared better positioned than the largest-cap benchmarks because of their lower concentration in mega-cap technology companies.

The S&P SmallCap 600 had gained 16.30% year to date through early October, compared with 13.79% for the S&P 500. This performance suggested relative strength among smaller companies, although comparable weekly closing figures for both indices were not reliably available.

The Russell 2000’s 2.1% weekly gain provided additional evidence of a rotation towards smaller businesses. Meanwhile, the broader NYSE Composite’s diversified sector exposure offered a different perspective on market performance, although its exact weekly return was not confirmed.

Market breadth remained uneven. More than 400 S&P 500 stocks reportedly fell on Friday, even as eight sectors were said to have gained over the week. This contrast showed that individual stocks and sectors were experiencing very different conditions beneath the headline index movements.

Energy Stocks Gain 2.4% as Brent Crude Climbs Above $112 a Barrel

Energy was among the strongest-performing sectors as geopolitical tensions and supply disruptions pushed oil prices higher. The sector gained 2.4% on Friday, while Brent crude remained above $112 a barrel following a roughly 4% surge on Thursday.

Supply concerns were linked to attacks on Saudi energy infrastructure and disruptions in Libya and Russia. Brent approached a reported weekly high of $113.17, while West Texas Intermediate crude traded near $98 a barrel after gaining almost 8% in the previous week.

Higher crude prices supported energy producers but increased cost pressures for airlines, freight operators and other fuel-intensive businesses. Sustained increases could also reduce household purchasing power and weigh on discretionary spending.

Oil’s strength created a difficult backdrop for monetary policy. While weaker employment supported expectations of a Federal Reserve pause, rising energy prices threatened to prolong inflationary pressure.

VIX Near 19 Signals Elevated Caution Rather Than a Full Market Panic

The CBOE Volatility Index (VIX), commonly known as Wall Street’s fear gauge, ended Friday near 19.03, according to Saxo. This was above its reported 2026 average of 18.12 and indicated continued demand for protection against market swings.

The VIX had closed Monday at 18.82 after opening at 18.37. A reported high of 22.31 occurred on 16 October, before the week under review, while the reported low was 15.72.

The index’s level suggested that investors remained cautious but had not necessarily entered a state of extreme market panic. The principal concern was the financing and cash-flow outlook for AI infrastructure, rather than confirmed systemic distress across financial markets.

Full-week data for the VIX3M and Nasdaq-specific VXN were not reliably available, limiting further conclusions about differences between short-term and longer-term volatility expectations.

Markets Price a 90% Chance of a Fed Hold Despite Inflation Rising to 3.7%

The Federal Reserve entered its pre-meeting blackout period ahead of the 28 October policy decision, leaving investors focused on recent inflation and employment data.

CME FedWatch placed the probability of no rate change at approximately 90%, with the federal funds rate expected to remain at 3.75%–4.00%.

The September employment report showed that the US economy added only 29,000 jobs, compared with forecasts of roughly 84,000–90,000. Downward revisions of 60,000 to previous months added to concerns about the labour market and strengthened expectations that policymakers would pause further rate increases.

Inflation presented a competing challenge. September consumer prices rose 0.6% month over month and 3.7% year over year, up from 3.4% in August. Core CPI increased to 2.6% year over year from 2.4%.

The combination of weaker hiring and persistent inflation left policymakers facing conflicting signals. Lower rates could support economic activity, but rising oil prices and elevated inflation limited the scope for an immediate easing of policy.

Treasury Yields Fall as Much as 20 Basis Points as Growth Concerns Dominate

Treasury yields declined across maturities during the week. The two-year yield fell from approximately 4.81% to 4.64%, while the five-year yield declined from 4.91% to 4.75%.

The 10-year yield dropped from around 5.15% to 4.95%, a decline of approximately 20 basis points. The 30-year yield fell from 5.42% to 5.29%, down about 13 basis points.

The two-year/10-year yield spread narrowed to approximately 0.30 percentage points, compared with 0.35 points the previous Friday.

Lower yields can support utilities and real estate by reducing the relative appeal of fixed-income alternatives and potentially easing financing costs. However, the reason for the decline was crucial: investors were seeking safety amid growth and credit concerns, rather than responding to clear evidence that inflation had subsided.

This distinction explains why the Treasury rally failed to produce a sustained recovery in technology stocks. Lower benchmark yields could not eliminate concerns about the profitability and financing of AI infrastructure.

Gold Falls Nearly 3% as the Dollar Recovers to 101.75

Commodity and currency markets reflected the competing effects of geopolitical risk, inflation concerns and demand for safe-haven assets.

Gold traded near $4,025 an ounce after falling almost 3% on Thursday, reaching its lowest level since 20 July. Silver slipped 0.1% to $54.49 an ounce, while copper declined approximately 2% amid concerns about industrial demand.

Oil moved in the opposite direction. Brent crude remained above $112 a barrel, while WTI traded near $98, keeping attention on the potential inflationary consequences of higher energy costs.

The US Dollar Index recovered to 101.75 on Friday, gaining 0.16% during the session after touching 101.44 on Thursday. EUR/USD fell 0.15% to 1.1198 and was on track for a weekly decline of approximately 0.42%, amid renewed concerns about French fiscal conditions.

USD/JPY traded near 156.76, close to a three-week low, as safe-haven demand supported the Japanese yen. Full-week GBP/USD and USD/CNY figures were not reliably available.

Dow’s 0.7% Gain and Semiconductor Losses Reveal a Market Divided Over AI

The week’s contrasting index performances revealed a market increasingly concerned about the financial sustainability of the AI investment boom.

The Dow gained approximately 0.7%, while the S&P 500 declined around 0.2% and the Nasdaq lost roughly 0.5%. Meanwhile, the Russell 2000 advanced 2.1%, and the semiconductor index fell as much as 6.72%.

These differences reflected a rotation away from some of the market’s largest growth companies towards energy, smaller businesses and defensive sectors. Brent crude above $112 supported energy producers but complicated the inflation outlook, while the decline in Treasury yields reflected concerns about growth and credit risk.

The next test will be whether major technology companies can demonstrate that AI-related capital expenditure generates sufficient revenue and free cash flow to justify continued investment. Investors will also assess whether credit spreads stabilise and whether weaker employment data outweighs persistent inflation in the Federal Reserve’s policy calculations.

A rate hold could provide greater certainty for markets, but it would not resolve concerns about AI financing or investment returns. If credit conditions improve and companies demonstrate stronger cash generation, technology shares could recover. If financing costs and credit spreads continue to rise, semiconductor and growth stocks may remain vulnerable even with the 10-year Treasury yield below 5%.

The week’s defining tension was the divergence between falling Treasury yields and a weakening growth-stock complex, a combination that signals credit-driven risk aversion rather than rate-relief optimism. The Dow’s defensive tilt and the Russell 2000’s snapback underscored that selling was concentrated in mega-cap technology, while energy’s surge and gold’s slump reflected a complex inflation-and-safety trade. Market participants will watch the 28 October FOMC decision, the first estimate of Q3 GDP and September PCE inflation for confirmation of whether the AI-financing shock remains a sector-specific de-rating or evolves into a broader growth scare.
