Q4 Active Management Pulse: Early cracks in market concentration favor stock pickers

Early cracks in concentrated AI-led equity markets are creating a broader opportunity set for disciplined stock pickers.

• AI remains the dominant structural theme, but managers are shifting their focus from infrastructure spending toward monetization, capital efficiency, token economics, power availability, and the durability of earnings.
• Information Technology now represents approximately half of the Russell 1000 Growth Index, versus 20% a decade ago; the July long-short unwind exposed crowded factor exposures and led some managers to cut gross exposure, cover shorts, tighten position limits, and increase hedging.
• Higher long-term bond yields, elevated energy prices, and persistent inflation favor companies with pricing power, resilient earnings, and strong balance sheets, while pressuring long-duration growth stocks and lower-income consumers.
• Opportunities are broadening beyond U.S. mega-cap technology into European healthcare, industrials, software, and financials; UK mid-caps benefiting from restructuring and asset disposals; and Japanese companies supported by domestic investment, wage growth, and corporate reform.
• Emerging markets remain uneven: Taiwan and Korea are central to the AI supply chain, while Brazil, South Africa, ASEAN, and selected frontier markets offer less crowded alternatives; China faces property and demand weaknesses, whereas India combines strong structural growth with demanding valuations.

Takeaway: Investors should retain selective AI exposure but diversify across sectors, regions, and return drivers, using disciplined position sizing and company-level research to manage concentration, valuation, rate, energy, and geopolitical risks.
