KEY TAKEAWAYS

  • Systematic investing combines human expertise with data and technology to bring together the art and science of investing.
  • We believe systematic strategies play a valuable role in portfolios—well positioned for the digital age and effective in pursuing outcomes like outperformance, income, and diversification.
  • The iShares U.S. Equity Factor Rotation Active ETF (DYNF) is an example of an ETF that employs a systematic approach to seeking consistent alpha.

WHAT IS THE SYSTEMATIC APPROACH TO INVESTING?

Systematic investing is an active approach to investing that emphasizes data-driven insights, scientific testing of investment ideas, and advanced computer modelling techniques to construct portfolios.

This process includes a comprehensive examination of empirical evidence by seasoned investment experts — testing different combinations of variables and comparing the results to known outcomes. This ability to validate insights means portfolio decisions are firmly evidence-based and not dependent on human conviction alone. Today’s data rich environment — data creation and storage has increased by a factor of 100 over the past 15 years1 — gives power to systematic managers who use large language models (LLMs) and machine learning algorithms to extract signals from a sea of data.

Signal boom

The increase in investment signals used by BlackRock Systematic

There are tens of thousands of data inputs, which can help lead to investment signals. For example, looking across online job postings as COVID-19 lockdowns eased, BlackRock’s systematic team found that demand for dog walkers was a significant data point. This data showed real-time movement toward reopening on a state-by-state level, reflecting a wider availability of vaccines and return to office mandates. This is one example of how we use alternative data sets — in this case, job postings for dog walkers — to uncover timely insights on the economy and companies.

To be clear, having expert investors at every step of the process is essential. Systematic investing combines human expertise with technology to bring together the art and the science of investing. We believe the systematic principles of investing at scale with big data, technology and human insight can serve many different investment goals, including seeking alpha — or returns in excess of a broad benchmark — through our exchange traded funds (ETFs).

OUTPERFORMANCE, INCOME AND OTHER USES OF SYSTEMATIC INVESTING

The consistent outperformance targeted by our systematic ETFs can help boost returns while also reducing overall risk and volatility — desirable outcomes in any market cycle, and especially valuable in today’s environment of heightened volatility.

Here are examples of actively managed iShares ETFs that leverage BlackRock’s systematic platform.

CONCLUSION

Systematic investing has a rich history of evolution. At its core, it combines rigorous thinking and economic intuition with advanced forecasting techniques — including statistical analysis, economic modeling, and now, machine learning and artificial intelligence. These methods are applied to an ever-expanding universe of data sources. In today’s digital age that data goes beyond traditional financial information to capture sources like news stories, web traffic, social media sentiment, and consumer geolocation patterns.

We see a world of opportunity in systematic investing. Combining human insight with the power of AI and big data brings new levels of precision and efficiency to the investment process — helping uncover actionable insights and drive better portfolio outcomes.
