FAQs: Investment Strategy & Solutions Group (iStrat)
Our Investment Strategy & Solutions Group, or iStrat, provides client-focused investment solutions, research, and advice. The integration of investment-driven research and portfolio management distinguishes iStrat, enabling the management of diverse strategies and the creation of custom solutions for clients. iStrat brings together three specialized skill sets, with its Multi-Asset Team, Next Generation Thematic Team, and Fundamental Factor Team.
We define thematic investing as the identification and exploitation of top-down, innovative, or disruptive structural trends that have the potential to drive above-average returns for companies aligned with those trends. Returns to themes cannot be easily explained by traditional country, sector, or style factors.
While thematic investing can be applied to different asset classes, it is often expressed via equities, where the broadest opportunity set can be found. Examples of equity themes include fintech, the future of education, energy efficiency, and automation. By investing in companies within these themes, investors are acting on the belief that their growth potential is not yet fully appreciated by the market but will be over time. Thematic investments often span multiple sectors, which may offer investors a differentiated way to diversify their equity allocations.
Our Multi-Asset Team’s process starts with understanding a client’s objectives, risk tolerances, and implementation considerations. We then develop solutions through:
- Strategic asset allocation — Risk-focused asset allocation with a longer time horizon
- Manager research and security selection — Identification of underlying managers and exposures, with a focus on delivering security-selection alpha
- Active allocation — Discrete processes that seek to enhance returns and mitigate risk
Factors are quantifiable characteristics that explain risk and return, such as “value” — a low stock price relative to a company’s earnings. Decades of industry and academic research have shown that these factors can potentially outperform markets at lower cost than traditional stock-picking strategies. Factors fall into broad categories with different performance profiles throughout the market cycle, and when combined, can have potential diversification benefits.
