Innovation In Indexing: Why Passive ETFs Matter

For many of us, ETFs have been synonymous with passive management. Since the early 1990s, ETFs have followed in the footsteps of the most well-known passive ETF — the S&P 500 ETF Trust (SPY). And even today, ETFs have a reputation for their accessibility and simplicity.

Recently, active management has brought another layer of evolution (with potentially higher returns) to the ETF world. As a result, active ETFs have seen rapid development. Most new ETF launches are now active ETFs. In fact, out of the 300+ ETFs launched this year, less than 10% are passive ETFs. We shouldn’t, however, confuse passive management with passive ideas. Passive management (i.e., index investing) continues to innovate and simplify complex investment ideas through factor-based and other proprietary weighting methodologies. It also provides investors access to new or niche asset classes, and redefines evolving industries.

Passive ETFs Do Not Lack Conviction

One of the most common misconceptions has been that active ETFs equal innovation, while passive ETFs equal neutrality. After all, most passive ETFs track indexes as part of investors’ long-term holdings. These “set and forget” strategies are straightforward, broad categories. These ETFs can have a relatively simple methodology, like the S&P 500, which is weighed by market capitalization. This is one of the biggest benefits of many ETFs — they are straightforward and work efficiently. That makes them attractive to retail investors. But it is easy to start viewing passive ETFs as “passive” in other senses. In other words, passive investing doesn’t mean investing without a strong investment thesis or investing in “plain vanilla” due to lack of ideas.

Passive ETFs and their indexes can also be innovative and support new strategies. Many use alternate weighting schemes like revenue or factor weighting. These indexes may also incorporate exclusions to create a more “active” feel. Many also use advanced optimization and other technology to run scenarios. And, finally, there are still plenty of passive ETFs that thrive in the disruptive technology space and play an important role in defining new industries or asset classes. This includes anything from thematic equities (new disruptive industries) to emerging asset classes that may be difficult to invest in outside of the ETF structure (e.g., digital assets and private markets).
