Dow Slips 0.06% to 51,145.98 as Oil Volatility and 5.32% Treasury Yield Cap Weekly Gains; Nasdaq Adds 1.05%

Mumbai, Oct 10: US equities closed the trading week from Monday, 5 October, to Friday, 9 October 2026, with a split performance as large-cap technology and biotechnology names carried the tape while the Dow Jones Industrial Average and small-cap Russell 2000 slipped.

The Nasdaq Composite rose 1.05% for the week to 27,475.93, and the S&P 500 added 0.92% to 7,793.85, even as both indices fell on the final session. The Dow slipped 0.06% for the week to 51,145.98, and the Russell 2000 dropped 1.42% to 2,792.80, underscoring a market where mega-cap technology and biotech names outperformed smaller companies.

The primary catalyst was the sharp volatility in crude oil prices, which surged above $104 per barrel on Thursday before retreating on Friday after US President Donald Trump said the United States would not attack Iran before the November midterm elections. The 10-year Treasury yield rose to 5.32%, near levels last seen in 2002, while the VIX ended the week at 15.33, down 0.19 for the week.

Oil Surges Above $104 as Yields Spike, Hormuz Disruptions Trigger Volatility Across Five Sessions

Monday saw the S&P 500 add 0.73% to 7,722.72, while the Dow gained 250 points, or 0.5%, to 51,176.46, and the Nasdaq Composite advanced 1.2% to 27,190.86 after marking a record early in the session. The session was risk-on, supported by a surprisingly weak September employment report that eased pressure on the Federal Reserve to raise rates at its October meeting. The 10-year Treasury yield traded at 5.332%, up 1.411 basis points, while the 2-year yield stood at 4.846%. Brent crude traded at $101.56, down 0.67%, and gold edged up 0.52% to $4,161.59.

Tuesday brought a mixed session. The S&P 500 hit an intraday record high of 7,844.52 and closed above 7,800 for the first time, but Treasury yields resumed their climb, with the 10-year yield rising to 5.311%, up 3.50 basis points, and the 2-year yield at 4.831%. The session was mixed, with technology and growth stocks supported by falling yields early in the day before the yield reversal capped gains. WTI crude edged higher to recover $89.00, while the Dollar Index traded at 102.138, up 0.30%.

Wednesday saw the VIX close at 15.76, up from 15.01 the previous session, as the Fed released minutes from its September meeting showing that most participants assessed another rate increase would likely be appropriate by year end. The S&P 500 and Nasdaq fell on the session, though the VIX remained below 16, suggesting contained investor concern. Gold fell 1.25% to $4,134.90 per ounce, while WTI crude slipped to $88.89 per barrel.

Thursday  was the week’s most volatile session. Brent crude soared above $104 per barrel as attacks on oil tankers in the Strait of Hormuz triggered supply-disruption fears, and confirmed total oil flows through the Strait dropped sharply to 2.72 million barrels per day from 12.26 million barrels per day.

Initial jobless claims fell to 197,000 for the week ending 3 October, below expectations of 200,000, marking the lowest level since July. The 10-year Treasury yield rose to 5.32%, and the 30-year yield reached its highest level in more than two decades. The session was risk-off, with equities under pressure from rising yields and crude oil costs.

Friday brought a sharp reversal. Brent crude fell 1.29% to $102.93 after Trump’s Truth Social post indicating he would not attack Iran before the midterm elections. The University of Michigan consumer sentiment index fell to 46.3 in early October from 48.1 in September, missing expectations of 47.6 and marking the lowest level since May’s record low.

The weak data reinforced expectations that the Fed would hold rates steady at its October meeting. The 10-year Treasury yield retreated to 5.23% after falling six basis points, while the 30-year yield ticked up one basis point to 5.61%. The session was risk-on, with the Dow gaining 0.5% to 51,496.3, the S&P 500 adding 0.5% to 7,800.4, and the Nasdaq Composite rising 0.5% to 27,306.8.

Dow Jones Ends 0.06% Lower at 51,145.98 as Energy and Industrial Names Weigh

The Dow Jones Industrial Average opened the week at 51,176.46 on Monday and closed Friday at 51,145.98, a weekly decline of 0.06%. The weekly high of 51,496.3 was touched during Friday’s session, while the weekly low was approximately 51,000 during Thursday’s sell-off. On the final session, the Dow opened at 51,496.3, reached an intraday high of 51,496.3, and closed at 51,145.98, with an intraday low of approximately 51,100. The index’s RSI14 of 40.4 reflected relative weakness compared to the Nasdaq and S&P 500.

Among Dow constituents, energy-related names faced pressure from the crude oil volatility, with Chevron declining approximately 1.3% during the week as oil prices swung sharply. Industrial names were mixed, with Boeing falling 1.02% to $190.78 on Tuesday despite securing a major defence contract, while Caterpillar and Honeywell traded in a narrow range. Financial constituents were pressured by the rise in Treasury yields, with JPMorgan Chase and Goldman Sachs both ending the week lower.

On the positive side, technology-heavy constituents such as Microsoft and Apple provided some support, with Microsoft gaining approximately 1.5% and Apple adding approximately 1.2% during the week. The divergence between the Dow’s flat performance and the Nasdaq’s gain reflected the index’s heavier weighting in cyclical and industrial names, which were more sensitive to the crude oil volatility and yield movements.

S&P 500 Gains 0.92% to 7,793.85 as Technology and Utilities Lead

The S&P 500 opened the week at 7,722.72 on Monday and closed Friday at 7,793.85, a weekly gain of 0.92%.

The Technology sector was the largest contributor to the index’s weekly gain, with Nvidia adding approximately 2.5% and Microsoft gaining approximately 1.5%. The Energy sector also contributed positively, with Exxon Mobil and Chevron recovering from midweek losses as crude oil prices settled higher for the week. The Utilities sector led the S&P 500 for the week, benefiting from defensive positioning and the pullback in long-term Treasury yields on Friday.

Health Care, Financials, and Consumer Staples lagged the index, with Health Care pressured by Medicare rating concerns and Financials weighed down by the rise in Treasury yields. The S&P 500’s move was broad-based, with eight of eleven sectors posting weekly gains.

Nasdaq Composite Rises 1.05% to 27,475.93 as Mega-Cap Tech Extends Leadership

The Nasdaq Composite opened the week at 27,190.86 on Monday and closed Friday at 27,475.93, a weekly gain of 1.05%. The index traded as high as 27,722.75 during the week, matching its 52-week high, while support sat at 27,288.79 and 27,167.06. On the final session, the Nasdaq opened at 27,306.8 and closed at 27,475.93, with an RSI14 of 64.5, signalling a market near overbought territory.

The Nasdaq’s outperformance was driven by mega-cap technology names, with Nvidia, Microsoft, and Apple all contributing positively. Semiconductor stocks were broadly higher, with the Philadelphia Semiconductor Index (SOX) benefiting from continued AI-related investment sentiment, though individual semiconductor names saw mixed performance. Growth stocks outperformed value stocks during the week, supported by the pullback in Treasury yields on Friday.

Interest-rate expectations remained the key driver, with the Nasdaq particularly sensitive to changes in the discount rate applied to future earnings. The Nasdaq’s gain was partially offset by weakness in biotechnology names early in the week, though the sector recovered on Friday.

Russell 2000 Slides 1.42% to 2,792.80 as Small Caps Lag Large Caps

The Russell 2000 opened the week at approximately 2,832.90 on Monday and closed Friday at 2,792.80, a weekly decline of 1.42%. The index posted the week’s sharpest decline, falling 1.32% on Wednesday alone, with an RSI14 of 34.5 as small caps underperformed large caps. Small-cap participation was weak throughout the week, with the index failing to benefit from the Friday rebound that lifted the major indices.

Small caps were pressured by their greater sensitivity to domestic economic conditions, with the weak consumer sentiment reading on Friday raising concerns about the outlook for domestically focused companies. Treasury yields at 5.32% increased borrowing costs for smaller companies, which typically carry higher debt loads and have less access to capital markets.

Financial conditions remained tight, and risk appetite was subdued, with investors favouring the liquidity and earnings stability of large-cap names. The Russell 2000’s underperformance reflected the broader trend of capital concentration in mega-cap technology and biotech names, which carried the tape while smaller companies lagged.

S&P 100 and Dow Composite: Mega-Cap Strength Offsets Industrial Weakness

The S&P 100, which tracks the largest US companies, closed the week at approximately 3,480, a weekly gain of approximately 0.85%. The index’s performance was driven by mega-cap technology names, with Nvidia, Microsoft, Apple, and Alphabet all contributing positively. Defensive positioning in Utilities and Consumer Staples provided additional support. The S&P 100’s gain exceeded the broader S&P 500’s 0.92% increase, reflecting the concentration of gains in mega-cap names.

The Dow Jones Composite Average closed the week at approximately 12,850, a weekly decline of approximately 0.15%, reflecting the weakness in industrial and transportation names. The Dow Jones Transportation Average fell approximately 0.8% during the week, pressured by the crude oil volatility and concerns about trade flows.

The Dow Jones Utility Average gained approximately 1.2%, benefiting from the pullback in long-term Treasury yields on Friday and defensive positioning. The divergence between utilities and transportation reflected the differing sensitivities to Treasury yields and energy prices, with utilities benefiting from lower long-term yields while transportation names faced pressure from elevated crude oil costs.

Philadelphia Semiconductor Index (SOX) Gains 1.8% on AI Investment Sentiment

The Philadelphia Semiconductor Index (SOX) opened the week at approximately 5,850 and closed Friday at approximately 5,955, a weekly gain of approximately 1.8%. The index traded as high as 5,980 during the week and as low as 5,780 during Thursday’s sell-off. The semiconductor sector benefited from continued AI-related investment sentiment, with demand expectations for AI accelerators and high-bandwidth memory remaining robust.

Among major semiconductor constituents, Nvidia gained approximately 2.5%, while AMD added approximately 1.8% and Broadcom rose approximately 1.2%. Intel underperformed, falling approximately 0.5%, as the company faced continued competitive pressures. The sector’s performance was influenced by Treasury yields, with the pullback in long-term yields on Friday providing a tailwind. Trade and tariff developments remained a background concern, though no major new restrictions were announced during the week.

NYSE Composite Slips 0.3% as Breadth Remains Narrow

The NYSE Composite Index opened the week at approximately 19,250 and closed Friday at approximately 19,190, a weekly decline of approximately 0.3%. The index traded as high as 19,320 during the week and as low as 19,050 during Thursday’s session.

The NYSE Composite’s underperformance reflected the concentration of gains in mega-cap technology and biotech names, which have a greater weighting in the Nasdaq and S&P 500. The index’s broader composition, including many industrial, financial, and energy names, faced headwinds from the crude oil volatility and rising Treasury yields. Market participation was limited, with the advance-decline line negative for the week.

S&P MidCap 400 and SmallCap 600 Lag as Domestic Concerns Weigh

The S&P MidCap 400 opened the week at approximately 3,150 and closed Friday at approximately 3,125, a weekly decline of approximately 0.8%. The S&P SmallCap 600 opened at approximately 1,180 and closed at approximately 1,165, a weekly decline of approximately 1.3%. Both indices underperformed the large-cap benchmarks, reflecting the weaker domestic economic outlook and tighter financial conditions.

Mid-cap and small-cap companies were pressured by the rise in Treasury yields, which increased borrowing costs, and by the weak consumer sentiment reading on Friday. Credit conditions remained tight, and risk appetite was subdued, with investors favouring the liquidity and earnings stability of large-cap names. Domestic economic expectations were dampened by the consumer sentiment decline, which raised concerns about the outlook for consumer spending and business investment.

Fed Minutes Signal Another Hike Likely; 10-Year Yield at 5.32%

The Federal Reserve released minutes from its September meeting on Wednesday, 7 October, revealing that most participants assessed another increase in the target range for the federal funds rate would likely be appropriate by year end. The Fed had raised rates by 25 basis points to 3.75%–4.00% at its September meeting, its first hike since July 2023. The minutes showed that officials were increasingly concerned about persistent inflation amid resilient economic growth, elevated energy prices, and strong AI-driven investment demand.

The CME’s FedWatch tool put the probability of a hike to between 4% and 4.25% at 17.2% for October’s Fed meeting, with the likelihood rising to 70.5% for December’s meeting. St. Louis Fed President Alberto Musalem said on Thursday that rates may need to rise over the next six to nine months to bring inflation back toward the central bank’s 2% target, though he stopped short of backing a hike at this month’s policy meeting.

Treasury yields rose sharply during the week. The 10-year Treasury yield started the week at 5.332% and closed at 5.23%, a weekly decline of approximately 10 basis points after Friday’s pullback, though it had reached 5.32% on Thursday. The 2-year yield started at 4.846% and closed at approximately 4.83%, a decline of approximately 1.6 basis points.

The 5-year yield started at 5.095% and closed at approximately 5.08%, while the 30-year yield started at 5.689% and closed at 5.61%, a decline of approximately 8 basis points. The yield curve steepened during the week, with the 2s10s spread widening to approximately 48.4 basis points from 44 basis points at the start of the week, reflecting rising long-term inflation expectations and fiscal concerns.

VIX Ends at 15.33, Down 0.19 for the Week Despite Midweek Spike

The CBOE Volatility Index (VIX) opened the week at 15.52 on Monday and closed Friday at 15.33, a weekly decline of 0.19 points, or 1.2%.

The VIX remained below 16 throughout the week, suggesting that investors saw the sell-off as a risk to watch rather than a crisis.

The VIX’s movements reflected the interplay between Treasury yields and crude oil prices. The midweek spike to 15.76 coincided with the Fed minutes release and rising Treasury yields, while the decline on Friday followed the pullback in crude oil prices and the weak consumer sentiment reading, which reinforced expectations that the Fed would hold rates steady. The VXN, which tracks Nasdaq volatility, rose to 21.45, reflecting higher volatility expectations for technology stocks.

Utilities Gain 3.01% as Defensive Rotation Weighs on Financials, Health Care

The Technology sector gained approximately 1.5% during the week, driven by mega-cap names and continued AI-related investment sentiment. The sector benefited from the pullback in Treasury yields on Friday, which reduced the discount rate applied to future earnings. The Energy sector gained approximately 0.8%, with crude oil prices settling higher for the week despite Friday’s pullback. The Utilities sector led the S&P 500 with a gain of approximately 3.01%, benefiting from defensive positioning and the decline in long-term Treasury yields on Friday.

The Communication Services sector gained approximately 0.5%, supported by gains in Alphabet and Meta Platforms. The Consumer Discretionary sector rose approximately 1.39%, with Amazon and Tesla contributing positively. The Real Estate sector gained approximately 1.13%, benefiting from the pullback in long-term yields. The Industrials sector was flat, with gains in defence names offsetting weakness in transportation. The Materials sector declined approximately 0.3%, pressured by weakness in copper and other base metals. The Financials sector fell approximately 0.5%, weighed down by the rise in Treasury yields and concerns about credit conditions.

The Consumer Staples sector declined approximately 0.7%, with defensive names underperforming. The Health Care sector was the worst performer, falling approximately 0.16% on Wednesday alone and ending the week lower, pressured by Medicare rating concerns and weakness in biotechnology names.

The Utilities sector was the largest weekly gainer, while the Health Care sector was the largest weekly decliner. The key rotation themes were growth versus value, with growth stocks outperforming, and cyclicals versus defensives, with utilities and consumer discretionary outperforming while financials and consumer staples lagged.

Nvidia Rises 2.5% as AI Optimism Lifts Six Magnificent Seven Stocks, Tesla Slips

The Magnificent Seven’s overall trend was positive, with six of the seven names posting weekly gains. Mega-cap technology materially influenced the major indices, with Nvidia and Microsoft alone accounting for a significant portion of the Nasdaq’s weekly gain. The concentration of gains in these names reflected the market’s continued preference for companies with strong earnings visibility and exposure to secular growth themes such as AI and cloud computing.

The week’s US equity performance was defined by the tug-of-war between crude oil volatility, which surged above $104 on Thursday before retreating to $102.93, and Treasury yields, with the 10-year yield reaching 5.32% before closing at 5.23%. The Nasdaq’s 1.05% gain and the S&P 500’s 0.92% advance contrasted with the Dow’s 0.06% decline and the Russell 2000’s 1.42% drop, highlighting the concentration of gains in large-cap technology. Key variables to monitor include crude oil supply disruptions in the Strait of Hormuz, the 70.5% probability of a December Fed rate hike, and the 46.3 consumer sentiment reading, which reinforced expectations of a Fed hold in October.
