Record Highs Mask a More Fragile Macro Backdrop

Wall Street extended its rally for a ninth consecutive week, with the S&P 500 and Nasdaq closing at fresh record highs as investors continued to pour into artificial intelligence and technology-related names. Despite elevated inflation readings, rising geopolitical tensions and lingering concerns over interest rates, market sentiment remained firmly supported by strong AI-driven earnings and improving risk appetite.

Beneath the surface, however, markets continued to navigate a complex macroeconomic backdrop. Inflation remains above the Federal Reserve’s comfort zone, Treasury yields remain elevated, and investors are increasingly debating how long strong technology earnings can continue offsetting broader economic risks.

AI Infrastructure Becomes the Market’s Dominant Growth Story

Artificial intelligence remained the defining theme across markets this week.

The latest catalyst came from Dell Technologies, whose shares surged after reporting exceptionally strong demand for AI servers and data-centre infrastructure. The results reinforced growing investor conviction that AI spending is expanding beyond chipmakers and into the broader technology ecosystem, including hardware, networking, cloud infrastructure and enterprise software.

The rally also extended across semiconductor and AI infrastructure names, with investors increasingly viewing the sector as a multi-year capital expenditure cycle rather than a short-term technology trend.

Capital flows reflected that conviction. US technology-focused equity funds recorded another week of strong inflows as investors continued increasing exposure to AI-related opportunities.

Markets Shrug Off Higher Inflation

One of the more striking developments this week was the market’s ability to absorb inflation data that remained uncomfortably high.

The latest core personal consumption expenditures (PCE) inflation reading came in at 3.3% year-on-year, in line with consensus expectations, while the second estimate of Q1 US GDP was revised slightly lower to 1.6% annualised growth from the advance estimate of 2.0%. Despite evidence of moderating economic momentum and persistent inflationary pressures, equities continued advancing as investors focused on easing Treasury yields and resilient AI-related earnings.

The market’s response suggests that, for now, earnings momentum remains a more powerful driver than macroeconomic concerns.

Geopolitics and Oil Remain Key Swing Factors

Geopolitical developments involving Iran continued to influence markets throughout the week.

Reports of progress towards a temporary ceasefire helped ease concerns surrounding potential supply disruptions in the Strait of Hormuz, leading oil prices to retreat from recent highs. Lower energy prices provided some relief to investors concerned about inflation and helped support broader risk sentiment.

While tensions remain unresolved, markets responded positively to signs of de-escalation, particularly as lower oil prices could reduce pressure on both consumers and central banks.

A Narrow Rally Continues

Despite record highs across major indices, market leadership remains concentrated.

Technology, semiconductors and AI-related sectors continue driving the majority of gains, while many other sectors remain comparatively subdued. Investors are increasingly monitoring whether market breadth can improve beyond a relatively small group of mega-cap technology companies.

At the same time, Treasury markets remain a critical focus following recent volatility in long-dated yields. Investors are paying close attention to Treasury auction demand, fiscal deficit concerns and Federal Reserve commentary for signals on the future direction of rates and liquidity conditions.

The combination of strong AI optimism, easing oil prices and resilient investor flows continues to support equities. However, elevated valuations and persistent inflation risks suggest that market sensitivity to future economic data may increase over the coming months.

What to Watch This Week (Beginning 1 June 2026)

a) Inflation and Economic Data

Last week’s focus was on whether elevated inflation and rising Treasury yields would begin exerting greater pressure on equities. While core PCE inflation remained firm at 3.3% year-on-year, in line with expectations, markets largely absorbed the data as Treasury yields moderated from recent highs and oil prices eased following signs of de-escalation involving Iran.

The key event this week will be Friday’s US Non-Farm Payrolls report. Markets will be closely watching whether the labour market continues to show resilience despite tighter financial conditions and slowing first-quarter economic growth. A stronger-than-expected report could reinforce concerns that interest rates may remain higher for longer, while weaker data may support expectations for eventual policy easing later in the year.

Investors will also monitor ISM Manufacturing and Services PMI data for further signs on the direction of US economic activity following softer GDP figures and moderating consumer spending trends.

b) Treasury Yields and Federal Reserve Expectations

Treasury yields remain another critical variable for equity markets, particularly for high-growth technology and AI-related sectors that continue driving market performance. Markets will also watch upcoming Treasury auctions and Federal Reserve commentary closely for further signals on liquidity conditions and interest-rate expectations.

c) US-Iran Tensions and Oil Markets

Geopolitical developments involving the US-Iran conflict will remain another major focus for markets. Investors will be closely monitoring whether recent ceasefire discussions and negotiations surrounding the Strait of Hormuz continue to make progress after signs of de-escalation helped ease oil prices last week. Any renewed military escalation or disruption to shipping routes could quickly reignite volatility across energy markets and complicate the inflation outlook.

d) AI Momentum and Market Leadership

Meanwhile, AI-related momentum remains firmly intact following strong earnings and spending announcements across the sector. Investors are likely to continue focusing on semiconductors, AI infrastructure and next-generation computing themes, although market leadership remains increasingly concentrated around a relatively small group of technology names.

The broader question for markets is whether resilient economic data and AI-driven earnings growth can continue offsetting inflation concerns, elevated valuations and narrowing market breadth as the second half of the year approaches.
