Huge profits at tech and energy companies are masking this key trend

S&P 500 year-on-year earnings growth is tracking near 30%, but FactSet data indicates growth excluding tech and energy is expected to slow to 7% in Q3 from 12% in Q2. BofA forecasts earnings growth of 130% for chipmakers and 122% for energy companies; those sectors have risen 36% and 49%, respectively, in 2026. BofA strategist Savita Subramanian warned that high expectations, dependence on AI capex and monetization, higher capital costs, and geopolitical bottlenecks could pressure the broader market if results disappoint.

Analysis

The key risk is not simply an earnings miss; it is index concentration in a small number of earnings engines. If AI capex or energy profits disappoint, slower growth elsewhere leaves fewer sectors able to absorb the downgrade, raising the chance of multiple compression as well as lower EPS. That makes headline index growth a poor proxy for breadth. Elevated expectations after strong sector performance also create asymmetric near-term reactions: merely meeting forecasts may not support further rerating.

Over days, single-company bank results are weak evidence of a broad earnings turn; dispersion across JPM, WFC, C and GS argues against extrapolating one report to the group. UNH’s outlook is a separate company-specific positive, not evidence that non-tech/non-energy growth has reaccelerated. Over 1–3 months, track estimate revisions and guidance breadth, alongside rates and indicators of AI infrastructure spending. Over 6–18 months, the structural test is whether AI investment converts into customer revenue and returns sufficient to sustain capex; geopolitical disruption can simultaneously support energy earnings and raise cost, inflation and rate risks.

Contrarian point: the concentration is visible, so a blanket short of tech or energy risks fighting durable earnings momentum. The better-defined vulnerability is cap-weighted index exposure versus the rest of the market. A broad de-rating is not inevitable if AI monetization broadens and ex-leader earnings stabilize.

Key Decisions for Investors

• Consider a modest long RSP / short SPY relative-value position to express improving breadth versus mega-cap concentration, rather than outright shorting the leaders. Enter in tranches during the reporting period; the thesis is falsified if estimate revisions broaden mainly among the largest constituents and the relative performance gap continues widening.
• Avoid chasing the reported sector earnings-growth forecasts as standalone evidence of upside. For the next 1–3 months, monitor semiconductor and energy guidance versus actual results, AI-related customer spending, and the breadth of upward versus downward S&P 500 estimate revisions; cut the relative-value exposure if breadth improves materially.
• Keep index downside hedges conditional, not automatic: consider a limited-risk SPY put spread only if earnings revisions deteriorate while rates rise or geopolitical bottlenecks threaten AI supply. Reassess if capex plans and monetization indicators remain intact and non-leader earnings stabilize; no company-specific trade in the mapped bank or UNH names follows from this sector-level signal alone.
