Q3 Active Management Pulse: AI reshapes the opportunity set

Key takeaways

• Managers are committed to the long-term AI investment cycle but are expanding implementation beyond hyperscalers into infrastructure, enterprise software, power, and industrial beneficiaries.
• Mega-cap IPOs, benchmark reconstitutions, and persistent market concentration are reshaping portfolio construction and reinforcing the value of active management.
• Valuation dispersion is creating attractive opportunities across healthcare, financials, industrials, and consumer staples as capital remains concentrated in AI beneficiaries.
• Regional positioning is becoming more differentiated, with Europe benefiting from infrastructure investment, Japan providing a more supportive backdrop for active managers, Asia remaining central to the AI supply chain, and selective opportunities emerging in U.S. consumer businesses.

The themes driving equity markets are familiar, but how managers are expressing conviction is evolving. AI remains a defining long-term investment theme, yet the conversation has shifted from maintaining exposure to refining implementation. At the same time, persistent market concentration, benchmark changes, and widening valuation gaps are expanding the opportunity set for active managers.

Managers are becoming more selective in where they deploy capital. They are balancing structural growth opportunities with valuation discipline while looking beyond crowded areas of the market for differentiated sources of return. As breadth improves across sectors and regions, stock selection remains central to capturing opportunity while managing risk.

Managers continue to view AI as a multi-year structural investment opportunity, though positioning has become increasingly nuanced. Earlier in the cycle, portfolios largely concentrated on hyperscalers, semiconductor leaders, and memory producers. Today, managers are expanding exposure across the broader ecosystem supporting AI deployment.

High-conviction areas include electricity generation, grid infrastructure, cooling systems, networking equipment, enterprise software, industrial automation, and data centers. These businesses are viewed as critical enablers of continued AI adoption and offer additional ways to participate in the investment cycle beyond the largest technology companies.

As the opportunity matures, managers are placing greater emphasis on capital intensity, earnings durability, and monetization. Elevated valuations across portions of the AI ecosystem leave less room for execution missteps, making disciplined implementation just as important as thematic conviction.

AI is reshaping market structure as persistent concentration, anticipated mega-cap IPOs, benchmark reconstitutions, and strong passive flows alter index composition. For active managers, these structural changes are creating both new opportunities and new portfolio construction considerations.

Several AI-related companies are expected to enter public markets over the coming quarters, potentially becoming meaningful benchmark constituents shortly after listing. At the same time, benchmark reclassifications are shifting some large technology companies between growth and value indices, changing active weights across style portfolios. Managers are responding by reassessing position sizing, benchmark risk, and where differentiated stock selection can add the most value as market concentration evolves.

Rather than viewing these developments simply as benchmark events, managers increasingly recognize that evolving index composition and concentrated passive ownership can create pricing inefficiencies. These market dynamics reinforce the importance of active management in identifying opportunities that extend beyond benchmark weights.

The concentration of capital into AI beneficiaries has created meaningful valuation dispersion across the broader market. Managers see compelling opportunities among high-quality businesses that have received comparatively less attention.

Healthcare, consumer staples, financials, and industrials have emerged as favored areas where resilient earnings, strong balance sheets, and attractive cash flow profiles support long-term return potential. Financials are compelling following years of balance sheet repair and disciplined capital allocation, while select industrial companies continue to benefit from structural investment themes extending beyond technology.

Managers are not rotating away from AI. Instead, they are using widening valuation gaps to build more balanced portfolios that combine structural growth with attractive risk-adjusted opportunities elsewhere in the market.

Regional positioning continues to reflect differentiated investment drivers rather than broad geographic allocations. In Europe, managers increasingly favor companies tied to electrification, defense spending, automation, and the infrastructure supporting AI adoption. Across Asia, Taiwan's specialist AI supply chain and Korea's technology ecosystem remain important areas of focus, while managers are also expanding exposure into financials and companies benefiting from corporate reform.

Japan has also stood out among developed markets. Approximately 55% of Japan equity managers outperformed during the period, supported by stronger leadership from value and high-dividend stocks alongside gains in energy-related exposures. The backdrop contrasted with several other developed markets, where concentrated sector leadership created stronger headwinds for active positioning. A more balanced factor environment has helped differentiated Japan, providing a supportive backdrop for active stock selection.

Within the United States, managers are beginning to identify encouraging signs in selected consumer businesses as improving household wealth and market performance support spending trends. At the same time, they remain mindful that parts of the recent rally have extended into lower-quality and more speculative areas of the market.

Emerging markets still require a highly selective approach. Brazil is attractive on compelling valuations and improving earnings expectations, while China presents targeted opportunities in automation and advanced manufacturing despite ongoing weakness in the property sector and uneven consumer demand. Across regions, managers are prioritizing company-specific fundamentals over broad macro positioning.

Active managers are refining portfolio implementation rather than altering long-term conviction. AI remains a structural growth theme, but opportunities are expanding across the ecosystem supporting adoption while widening valuation dispersion is creating attractive entry points beyond technology. At the same time, evolving market structure, benchmark changes, and persistent concentration are increasing the importance of disciplined portfolio construction and active stock selection. As opportunities broaden across sectors and regions, active management is well positioned to capitalize on differentiated sources of return.
