How does enhanced indexation work?
Each of our Enhanced Index strategies is based on an equity benchmark. Using a rules-based approach, we continuously evaluate every company in the index, with a focus on three key factors – Value, Quality and Momentum.
Beginning with index weights, stocks are adjusted by a multi-factor score. This quantitative process controls for sector, stock, and country concentration, as well as macro risks like artificial intelligence trends or inflation. Positions are updated as risk views evolve.
- Value: Is the stock attractively priced?
- Quality: Are the company's fundamentals strong?
- Momentum: Does the market favour the stock?

Enhanced indexation blends active and passive investing styles. By combining the discipline of passive index investing with active multi-factor insights, Enhanced Index funds target cost-effective index outperformance.
Enhanced Index funds have the potential to deliver excess returns, unlike passive funds. They focus on cost-efficiency and aim to help investors diversify portfolios while reducing concentration risks versus passive funds.
Each style - Enhanced Index, passive, and active - has its place depending on investor needs. Sometimes all three are included in a portfolio. Enhanced Index allows investors to blend active and passive in one allocation.
Active funds can sharply outperform or underperform benchmarks, but fees can be high. Passive funds have low fees and their performance mirrors the benchmark. Enhanced Index portfolios blend active and passive approaches, aiming to modestly outperform benchmarks with diversified exposure to core equity markets.
Enhanced Index is a quantitative, data-led strategy. Managers systematically target positive return drivers or factors, blending index investing rigour with factor-driven quantitative insight for incremental outperformance at competitive fees.
Enhanced Index funds are designed to be cost-effective, and aim to deliver steady gains with the potential to compound over time. These funds can play the role of core equity building blocks, freeing up budget for complementary, higher cost, high-conviction strategies, like smaller companies, thematics, and alternatives.
