What Future Innovations Will Shape Investment Management

Technology and investment management are changing the way portfolios are constructed, monitored and governed. The two trends that will most affect the future of advisory firms and consulting businesses are AI and personalization.

AI and ML algorithms, currently used in niche applications, may evolve into the building blocks for dynamic risk pricing, scenario analysis and operational efficiencies. As algorithms become more powerful, asset managers will be able to process larger volumes of data, spot hidden correlations, quantify risk and monitor portfolio risk in near real time. Consulting firms are increasingly interested in how managers use AI for research or governance, not just as a performance-improvement tool.

Users increasingly expect more personalization across all services. Innovations such as direct indexing and customized portfolios enable more precise alignment with clients' investment objectives, tax considerations and risk appetites. Customization offers institutional investors the opportunity to satisfy their governance objectives by making allocations consistent with their funding objectives and policy constraints. Consulting firms have begun helping fiduciaries evaluate these opportunities while still maintaining overall coverage and uniformity.

Future developments will build on themes of transparency, accountability, and accuracy, but investment management consulting will remain integral to converting technological potential into disciplined, fiduciary-friendly decisions.

Selecting an Investment Management Consulting Partner

Investment management consulting brings fiduciary support to an increasingly complex and maturing U.S. investment management market. Investment management consulting firms that provide independent research, structure and governance may deliver greater value than standard performance measures. Organizations should consider their service scope, the depth of their research and whether their advice aligns with their oversight needs when choosing a long-term partner.
