AI-Led Mega-Cap Rally Narrows Market Breadth

AI optimism, catalyzed by breakthrough models and capex plans, powered mega-cap technology shares and lifted indices despite soft breadth. Earnings revisions favored enablers of compute and cloud. Equal-weight benchmarks lagged as cyclicals and small caps trailed. Credit remained accessible for quality issuers, while long rates drifted with sticky services inflation. The setup delivered returns but concentrated risk in a handful of names.

We viewed the rally as credible in its drivers but narrow in participation. Market history warns that narrow leadership can persist but eventually meets valuation and policy constraints. We preferred to own structurally advantaged franchises while moderating concentration. International markets with cheaper multiples and improving policy backdrops offered diversification. We monitored capex follow-through and monetization timelines for AI workloads.

In client portfolios we kept core exposures to leading platforms and semiconductors, trimming excesses to manage single-name risk. We added to equal-weight U.S. indices and selective international value where earnings yields were compelling. We funded moves by reducing lagging cyclical bets without clear catalysts. Hedging used downside collars given elevated skew and to protect gains in concentrated holdings.

We set criteria for adding breadth-sensitive exposure: improving ISM new orders, credit availability, and earnings revisions outside technology. We expected a bumpy path as policy stayed restrictive. Our stance aimed to participate while guarding against a narrow tape that can reverse sharply on guidance disappointments or rate surprises.
