Inflation Cools, Tech Cracks: Rotation Sweeps Global Markets

For the week ended Jul 17, global equities delivered a week of sharp contrasts as a broad rotation out of AI and semiconductor names collided with the most encouraging U.S. inflation data in over six years. U.S. stocks retreated as heavy selling in large-cap technology overshadowed cooler-than-expected inflation and strong bank earnings. Mainland Chinese markets fell steeply on AI valuation concerns and a second-quarter GDP miss, even as Hong Kong outperformed on resilient Southbound buying. Singapore quietly extended its year-to-date leadership, with the Straits Times Index grinding higher despite the global tech turbulence.

πŸ‡ΊπŸ‡Έ United States

Market Overview

Major U.S. indexes closed lower in a reversal of the prior week's large-cap tech outperformance, with the Nasdaq Composite (COMP) sliding -2.90% and the S&P 500 (SPX) losing -1.55%, while the Dow Jones Industrial Average (DJI) fell a more modest -0.93%. Information technology and communication services posted the steepest losses on selling in semiconductor, memory and AI infrastructure shares, while energy advanced alongside oil prices amid escalating U.S.–Iran tensions.

Index Weekly Performance

- Dow Jones Industrial Average (DJI): -0.93%

- S&P 500 (SPX): -1.55%

- Nasdaq Composite (COMP): -2.90%

 

Key Highlights and Outlook

1️⃣ CPI Posts Largest Monthly Decline Since April 2020

Headline CPI fell 0.4% month-over-month in June, well below the 0.1% decline expected, driven by a 5.7% drop in energy prices. Year-over-year inflation slowed to 3.5% from 4.2%, with core easing to 2.6%. PPI also surprised lower, falling 0.3% for the month.

2️⃣ Rate-Hike Odds Collapse; Fed Seen on Hold

The market-implied probability of a July rate hike dropped from roughly 40% to about 14% after the inflation reports. The Fed held rates at 3.5%–3.75% in June with a divided FOMC; rate cuts look off the table this year, but the bar for hikes remains high heading into the July 29 meeting.

3️⃣ Banks Kick Off Q2 Earnings With Broad Beats

JPMorgan Chase, Goldman Sachs and Citi topped consensus estimates, pointing to resilient loan growth, credit quality and consumer spending. Expectations for the season are lofty: S&P 500 Q2 earnings growth forecasts have been revised up from about 14% to around 25%, led by energy and technology.

4️⃣ Semiconductor and AI Infrastructure Selloff Deepens

Chip, memory and AI infrastructure shares sold off despite encouraging results from Taiwan Semiconductor and ASML. The SOX Semiconductor index is now down about 20% from its June highs but still up roughly 64% year-to-date, while software and cloud names like Microsoft and Salesforce showed signs of recovery.

5️⃣ AI Capex Guidance Is the Key Earnings Test

AI capex is expected to grow about 75% this year to USD 700–800 billion, before slowing to 25% in 2027 and 6% in 2028. Investors will watch whether hyperscalers reaffirm or exceed this guidance, and whether the spending is translating into revenue returns.

6️⃣ Consumer Resilient, Housing Still Soft

Retail sales rose 0.2% in June (+0.7% ex-gas stations) and initial jobless claims fell to 208,000, the lowest since early May. Housing lagged: pending home sales dropped 5.4%, homebuilder confidence declined, and the 30-year mortgage rate climbed to 6.55%, the highest since August 2025.

 

S&P 500 Sectors in Focus

Sector performance split cleanly along the rotation. Energy was the week's clear leader, advancing alongside oil prices amid U.S.–Iran tensions, with real estate and consumer staples also firmly higher as defensives held up. Technology was by far the weakest sector, dragged down by the semiconductor and AI infrastructure selloff, with communication services, consumer discretionary and industrials also in the red.

(Refer to the SPX sector ETF weekly performance table below.)

Technical Snapshot

The SPX pulled back -1.55% to 7,457, while the Nasdaq's -2.90% decline confirmed that leadership has rotated away from the AI complex for now. The DJI held up best, and all three benchmarks remain up 8.5%–9.8% year-to-date, keeping the broader uptrend intact. Near-term direction hinges on whether Q2 tech earnings and AI capex guidance can arrest the semiconductor slide. Technically, both SPX and Nasdaq have been in sideway consolidation over the past two months, while DJI has been in sideway consolidation over the past three weeks.

πŸ‡¨πŸ‡³ China / Hong Kong

Market Overview

China equities diverged sharply in a volatile week. A renewed sell-off in AI, memory-chip and semiconductor shares drove steep mainland losses, with the CSI 300 falling -5.26% and the Shanghai Composite (SSE) sliding -5.81%, while the Hang Seng Index (HSI) gained +1.60% on mainland buying through Stock Connect. A strong Tuesday rebound on better-than-expected trade data was more than reversed by Friday's rout on AI valuation concerns.

(Refer to the Hang Seng Index constituents' weekly performance table below.)

Index Weekly Performance

- CSI 300: -5.26%

- Shanghai Composite (SSE): -5.81%

- Hang Seng Index (HSI): +1.60%


Key Highlights and Outlook

1️⃣ Q2 GDP Misses at 4.3%, Underscoring Uneven Growth

GDP grew 4.3% year-over-year, below the 4.5% consensus and down from 5.0% in Q1, though first-half growth of 4.7% stayed within the 4.5%–5.0% target range. Industrial production rose a firm 5.3%, but fixed asset investment fell 5.7% in the first half, including an 18% slump in property.

2️⃣ Exports Surge 27% as External Demand Carries the Economy

June exports jumped 27.0% year-over-year, well above expectations, with imports up 36.0% and the trade surplus widening to USD 125.6 billion. Higher semiconductor prices and strong overseas demand for data-processing equipment and automobiles drove the gains, contrasting sharply with weak household consumption and property activity.

3️⃣ AI Valuation Concerns Trigger Friday Rout on the Mainland

Friday's sell-off was fuelled by concerns over elevated AI valuations and intensifying competition among Chinese large language model developers. Mainland losses narrowed late in the session as trading picked up in large index ETFs often favoured by state-backed investors, hinting at official support.

4️⃣ Hong Kong Outperforms on Southbound Flows

The HSI's +1.60% gain was supported by Stock Connect buying and strength in large internet platforms, automakers, healthcare and selected property names. OOIL (+12.58%), BYD Electronic (+10.20%) and Longfor (+9.34%) led constituents, while SMIC (-15.00%) and Lenovo (-12.50%) bore the brunt of the chip selloff.

5️⃣ Targeted Policy Over Broad Stimulus (Maybank KE)

Maybank KE expects Beijing to maintain a targeted policy stance prioritising AI, energy infrastructure and strategic industries rather than broad-based stimulus, favouring beneficiaries of industrial upgrading such as CATL, Lenovo, CITIC Securities and Henderson Land. June credit data stayed subdued, with new yuan loans of CNY 1.61 trillion missing the CNY 2.0 trillion consensus.

Technical Snapshot

The HSI added +1.60% to close at 24,562, extending its divergence from the mainland even as its year-to-date return remains modestly negative at -4.17%. The SSE's -5.81% weekly plunge to 3,764 marked a decisive break lower, dragging the index into negative territory for the year. Whether state-linked ETF buying and Southbound flows can stabilise mainland sentiment is the key near-term question.

πŸ‡ΈπŸ‡¬ Singapore

Market Overview

The Straits Times Index (STI) rose +0.73% to close at 5,509.43, quietly outperforming both Wall Street and mainland China for the week and extending its year-to-date gain to +18.58%. Breadth was mixed beneath the surface, with property, defensive and REIT names leading while industrials and tech-linked counters lagged.

(Refer to the STI weekly performance table below.)



Index Weekly Performance

- Straits Times Index (STI): +0.73%

 

Key Highlights and Outlook

1️⃣ STI Extends Year-to-Date Leadership

The STI's +0.73% advance to 5,509.43 came despite the global tech shakeout, underlining Singapore's relative-safety appeal. At +18.58% year-to-date, the index continues to outpace the S&P 500 (+8.94%) and the Hang Seng (-4.17%) by a wide margin.

2️⃣ Property and Defensive Names Lead the Advance

HK Land (+4.51%) topped the constituent table, followed by Keppel DC REIT (+3.57%), SATS (+3.12%) and Mapletree PACT (+2.29%). ThaiBev (+2.25%) and JMH (+1.98%) added to the defensive tilt as investors rotated away from cyclical and tech-exposed counters.

3️⃣ Banks Diverge Sharply

OCBC surged +4.12%, extending its standout +44.53% year-to-date run, and DBS added +2.14%. UOB was the outlier, sliding -4.30% for the week, though it remains up +21.14% for the year. The three banks' dispersion was the widest among the index heavyweights.

4️⃣ Industrials and Tech-Linked Counters Lag

Sembcorp Industries (-5.63%), Venture (-5.19%) and ST Engineering (-4.84%) were the week's biggest decliners, echoing the global rotation out of industrial and tech-adjacent names. SGX eased -1.49% but retains a strong +40.80% year-to-date gain.

Technical Snapshot

The STI closed at 5,509, holding comfortably above the 5,500 mark after a steady +0.73% weekly gain. The index's resilience amid heavy global tech selling reinforces the strength of its 2026 uptrend, now +18.58% year-to-date. A sustained hold above 5,500 would keep the path of least resistance pointing higher.

πŸ“… Week Ahead (20–24 Jul 2026)

In the U.S., Q2 earnings season broadens out beyond the banks, with investors focused on whether technology companies reaffirm lofty AI capex guidance and demonstrate revenue returns on that spending. With Q2 S&P 500 earnings growth forecasts revised up to around 25%, the bar for delivery is high. The July 29 FOMC meeting looms the following week, with hike odds sharply reduced after the soft CPI print.

In China and Hong Kong, markets will watch for policy signals following the Q2 GDP miss, with Beijing expected to lean on targeted support for AI, energy infrastructure and strategic industries rather than broad stimulus. Whether state-linked ETF buying and Southbound flows can steady mainland sentiment after Friday's AI-driven rout will set the near-term tone.

In Singapore, the STI's ability to hold above 5,500 amid global tech volatility will be in focus, alongside continued rotation into defensive, property and REIT names. Dispersion among the three banks bears watching after a week of unusually wide divergence.

πŸ—“️ Overarching Watchpoint

The single biggest binary risk of the week is whether technology earnings — and AI capex guidance in particular — can arrest the global semiconductor selloff. Delivery on lofty forecasts could see tech resume leadership; a disappointment risks extending the rotation and deepening the drawdown across U.S. and mainland Chinese markets.
