Index ETFs remain foundational for scale and efficiency — but investors are also additionally seeking strategies that can deliver incremental alpha without sacrificing transparency or cost discipline. State Street Investment Management has launched six Enhanced Active ETFs, which combine the exposure, liquidity, and low-cost attributes of index strategies with the added benefit of potential incremental alpha returns.

For investors holding a core index ETF, introducing an enhanced strategy is not about abandoning the philosophy of indexing, but rather optimising it. Enhanced is a purpose-built approach designed to deliver modest, but consistent outperformance through disciplined, risk-aware decision-making. Enhanced seeks to balance consistency with scalability, by operating within a clearly defined tracking error range of 1–2% on average. The process behind State Street’s enhanced equity offering is designed to deliver an objective of maximizing the information ratio (Figure 1). This approach preserves the foundational benefits of passive investing while leveraging the strengths of systematic active methods, where each unit of risk must be efficiently rewarded for clients.

Traditional fundamental or pure-alpha active managers often take unconstrained deviations from a benchmark, concentrating capital in high-conviction ideas. This can lead to both significant outperformance or underperformance, and importantly, may not be suitable for investors targeting a balanced asset allocation and risk profile. The decision to integrate enhanced active ETFs depends on an investor’s tolerance for tracking error. Enhanced strategies are designed to inhabit the "sweet spot" of active returns and are designed to provide a smoother return trajectory over a full market cycle compared with more unconstrained strategies.

Our Enhanced Active capabilities

State Street Enhanced Equity Strategies aim to provide a modest amount of excess return, before expenses, while closely adhering to benchmark characteristics. Our enhanced active strategies have shown solid risk-adjusted results, distinguishing themselves in both emerging market and developed market universes. Our track records demonstrate a beneficial mix of robust and consistent alpha, alongside thoughtful risk-controlled processes. The new share classes are based on existing SICAV funds. The figures below provide an example of the objectives (Figure 2) and performance (Figure 3) of our systematic enhanced approach using the emerging markets strategy as an example.

Quality control and outperformance potential

Enhanced active equity ETFs should not be viewed as a replacement for passive indexing, but as a powerful complement. Investors interested in balanced asset allocation can take advantage of scale through index equity ETFs while also layering on enhanced active strategies which introduce a mechanism for quality control, tactical agility, and potential outperformance. 

State Street Investment Management (“SSIM”) has long been a leader in index ETFs, with our first European-listed ETFs dating back to 2001. Index tracking ETFs have expanded significantly, since then, in assets and scope. Investors use ETFs as allocation tools to access a range of market-beta exposures at relatively modest fee levels, compared to traditional active funds. Now, appetite for active strategies is growing - since 2020, assets in European-listed enhanced active ETFs have increased at a compound annual growth rate of over 70%. Most assets are in global ($22.3 billion*) and U.S. ($17.5 billion) regional equities.1

How can investors navigate this theme?

At State Street Investment Management, our Enhanced Active investment team has an established track record of strong performance relative to the benchmark and to peers.
