The mood on Wall Street turned cautious on Friday as the S&P 500 and Nasdaq opened lower, with investors reassessing the strength of the AI-driven rally that has propelled markets for the past two years. Broadcom’s quarterly update, far from easing concerns, sharpened them. The chipmaker warned that margins on its AI system sales could be thinner going forward, even as it projected strong revenue. That single datapoint was enough to pull the broader semiconductor space into decline and reignite talk of an overextended AI trade.

The S&P 500 slipped 0.18% and the Nasdaq dropped 0.51% in early trade, while the Dow managed a 0.31% gain. The divergence reflected a rotation already underway: large-cap growth names are losing steam while industrials, financials, and small-caps continue absorbing flows. Nine of the 11 S&P 500 sectors traded higher, but the heavyweight technology cohort dragged the composite indices lower.

Broadcom’s 8.4% slide underscored the sensitivity of AI-linked stocks to any hint that the economics of AI hardware may not keep pace with forward-looking hype. The signal was amplified by a 1.5% drop in the broader chip index and further weakness in Advanced Micro Devices, which fell 1%. The pressure followed Oracle’s weak forecast a day earlier, reinforcing investor unease about demand visibility in high-growth cloud and AI ecosystems.

Market analysts noted that the same mega-cap technology stocks that led the market higher since October 2022 may now become catalysts for broader selling if earnings fail to justify aggressive valuations. Strong corporate guidance had been the stabilising force in AI-adjacent sectors; any wobble is now scrutinised more intensely.

Yet Thursday’s record closes in the S&P 500, Dow, and Russell 2000—and their continued trajectory toward weekly gains—reflect a market still supported by macro undercurrents. The Federal Reserve’s rate cut earlier in the week and its softer-than-expected guidance for future moves boosted risk appetite. Even so, dissenting Fed policymakers warned that inflation remains elevated, complicating the case for sustained monetary easing. Traders remain more optimistic, pricing in 50 bps of cuts by end-2026, exceeding the Fed’s signal.

The evolving rotation was visible in the Russell 2000’s superior performance this quarter. Investors are shifting from AI-heavy growth names into value-oriented sectors such as healthcare, aided by the view that the consumer backdrop is steadier than previously feared and that ample liquidity remains sidelined. Market participants argue that sectors that have not participated in the AI boom could benefit as capital redistributes.

Stock-specific volatility added texture to the session. Nvidia inched up 0.3% as reports indicated it may raise production of its H200 chips to meet robust Chinese demand-evidence that selective strength within AI hardware persists despite sector-wide caution. Lululemon Athletica jumped 12% after raising its annual profit forecast, while confirming a CEO transition. Meanwhile, cannabis-linked stocks surged after reports that President Donald Trump was evaluating a relaxation of marijuana restrictions, sending Canopy Growth up 23% and Tilray Brands up 30%.

Market breadth was supportive, with advancers outnumbering decliners on both the NYSE and Nasdaq. Still, the tension between cyclical optimism and valuation anxiety remains unresolved as markets weigh margin pressures, central-bank caution, and sector-specific divergences.

Why it matters for India

Indian markets have been closely correlated with US risk sentiment throughout 2025, particularly in technology and semiconductor-exposed themes. A sustained pullback in US AI names could temper momentum in India’s IT, chip-manufacturing, and cloud-services basket, even though India’s fundamentals remain domestically anchored. Conversely, a rotation toward value and cyclicals globally may reinforce flows into Indian banks, capital goods, and healthcare—sectors that have already drawn institutional interest.

Sector impact

Semiconductors and cloud-linked technology names globally may see near-term valuation pressure if margins compress. For India, where the semiconductor ecosystem is still nascent, the immediate impact is more sentiment-driven than earnings-linked. AI infrastructure spending trends in the US remain key signals for Indian IT exporters who depend on large transformation mandates from global clients.

Bull case

The Fed’s easing stance, combined with broad market liquidity and improving breadth, could limit downside and support a continued rotation rather than a market-wide correction. If AI demand normalises rather than collapses, margin concerns may prove temporary.

Bear case

If multiple large technology firms guide for weaker profitability, markets may reassess the entire AI capex cycle. A sharper correction in US tech could spill over into global equities, including India, where valuations are already elevated.

Risks

Key risks include slower AI infrastructure monetisation, policy uncertainty around US rate cuts, margin compression across semiconductor supply chains, and volatility from politically-driven regulatory announcements such as cannabis reform. For India, the main risk is a sentiment drag on IT and tech-adjacent sectors.
