Passive Investing Boom: Why ETFs Are Dominating the U.S. Market
Metric / TrendRecent Figures & Insights
Total U.S. ETF assetsU.S.-listed ETFs now hold over $10 trillion in assets
Global ETF AUMGlobal ETF assets rose to approximately $13.8 trillion by end-2024
Annual inflowsIn 2024, ETFs in the U.S. saw net inflows of about US$1.1 trillion, surpassing previous records.
Equity vs fixed incomeEquity-oriented ETFs led with the lion’s share of flows; fixed income ETFs also saw rising interest as yield seekers and risk diversifiers
Growth of active ETFsAlthough passive ETFs still dominate in terms of assets under management, active ETFs are growing fast: hundreds of launches, rising inflows, increasing share.
Fee gapsPassive ETFs tend to cost significantly less than comparable mutual funds. Investors are sensitive to fees.

What makes passive strategies & ETFs appealing

These are the primary motivations why average Americans are shifting to passive investing through ETFs:

  1. Low cost: Passive ETFs have low expense ratios most of the time. Because they don’t seek to over-perform the index, they have lower management fees, trading costs, etc. As time goes on, these savings compound, and this is especially true when holding for a long time.
  2. Simplicity & transparency: With ETFs, you know more or less what you are holding (assuming they are transparent), you know what index or index exposure the product is based on, and you know what to expect. You can eliminate stock selection and concern for individual manager skill to a degree.
  3. Diversification: Because index ETFs track an entire asset class, rather than a single company, the ETFs help to spread out risk among many potential assets – risk is reduced by spreading out idiosyncratic risk. Compared to a few individual stocks, this tends to take some of the volatility out of returns.
  4. Liquidity & flexibility: ETFs trade as if they were stocks in that investors can buy or sell ETFs throughout the trading day at market prices. Although Mutual Funds have 24-hour access, it comes with inherent flexibility that is sometimes not provided by mutual funds (sometimes you may have to be at the end of the day, prices/trading windows for access).
  5. Tax efficiency: The legal structure of ETFs (in the US, at least) often results in lower CGD than mutual funds. Rebalancing of indexes is less frequent than it would be if using cash instead for this purpose; “in-kind” creation/redemption mechanisms allow for that.
  6. Product innovation & variety: With demand increases come more types of ETFs – thematic, smart beta, fixed income, alternatives, commodities, and even crypto-linked ETFs. In this schematic, investors can view sectors or techniques that would previously have been pricey or difficult to obtain.
  7. Behavioural & institutional change: Model portfolios that consolidate their ETFs are more common with institutional and retail investors. Retirement plans and their financial advisors are moving away from mutual funds toward ETFs due to cost and transparency.

What passive doesn’t solve: risks & limitations

Although passive investing through ETFs could have heady benefits, it has several gaffes and pitfalls:

  • Market concentration & overlapping exposures: Due to the fact that a lot of ETFs work on standard benchmarks, the risk of concentration on several products holding the same largest and biggest titles of the companies is high. It implies that it seems diversified when it actually is not.
  • Performance ceiling & no alpha: Passive funds actually are performance-matching (with fees deducted). Passive investors absorb big drawdowns or big overvaluations of markets. They cannot hedge or pivot based on fundamentals as active management attempts to do.
  • Risk of passive “momentum” effects: Some studies caution that increasing amounts of money in index-linked vehicles can lead to market distortions (price distortion, liquidity problems, feedbacks). Some of these instances provoke the passive dominance leading to a decline in the marginal benefit of active managers- draw, but do not stem riskiness out into the system.
  • Limited strategic flexibility: In some regimes of the market (e.g. during the crisis, extremely volatile conditions), passive strategies could be behind active strategies that are capable of repositioning on their insight. Additionally, passive ETFs are less adequate with regard to some exposures (e.g., the private assets and certain niche sectors).
  • Fee differences still matter: This applies to individual portfolios as well as large portfolios since a small difference in fees (in basis points) can translate to significant differences after many years. Total cost (including, but not limited to, management fee) is to be compared by investors.

How the shift is changing behavior & market structure

As more money has poured into passive investing and ETFs, the decision has implications for how people think about investing, how markets are regulated and how markets behave.

  • Mutual funds losing ground: Large outflows from mutual funds are a preference for ETFs. Some mutual fund managers are changing share classes or launching ETF versions.
  • Growing acceptance of active ETFs: Rather than being picked up by the average investor as a cost-saving feature, many investors and advisors are drawn to active ETFs for their flexibility. Regulatory changes (like approving the structure of the new ETFs) are helping this happen.
  • Regulatory and product innovation: New ETF types (buffer defined outcome crypto alternatives) are hitting the market. Regulators appear to be more open to more complicated structures under ETF wrappers.
  • Smarter due diligence & advisor behaviour: With the increasing recognition of the value of cost, liquidity, tracking error, and tax implications of these “small” differences in ETFs, cost has become an important issue for clients and institutional investors.

What this means for everyday Americans — use cases & how to benefit

If you are a regular investor (not a hedge fund or big institution), here is how you can make the best bet on the ETF / passive investing trend:

  • Start with core ETFs: Hold foundation securities, like broad index ETFs, e.g., S&P 500, Total US Stock Market, Total International. They are cheap, give exposure, and have been doing well for a long time.
  • Layer in specialized exposure if needed: If you are interested in dividend income, environmental, social and governance criteria, sector tilt, or even an exposure to alternatives (commodities, for example), go for ETFs that meet those needs – but make sure that you understand costs, liquidity and risk of the ETFs that you own.
  • Mind fees & tracking error: Lower fee is not necessarily better, however – other factors to consider are how closely the ETF follows its benchmark, how big it is, and how liquid it is. An expensive ETF with better management can end up beating a cheaper ETF with higher tracking error.
  • Watch tax implications: Prefer ETFs in tax-efficient accounts. Understanding how distributions, capital gains and in-kind redemption impact taxation. Seeking to invest in tax-efficient ETFs if they are available.
  • Don’t ignore diversification across asset classes: Even with ETFs, they provide a balance between stocks, bonds, real assets, and international spread to minimise risk. Also consider the dynamics of correlation (i.e. during times of crisis, everything tends to go together).

Where passive investing might head over the next few years

Here is a list of some of the trends that we can envisage as they occur in the near future:

  • More active/passive hybrids: Smart-beta / factor ETFs, defined outcome ETFs (more passive index but have some strategy, outcome focus) will continue to expand. They will frequently provide a middle ground between the relatively expensive active funds and the purely passive investment approach in terms of lower fees, greater flexibility and/or more control over risk.
  • Alternative assets via ETFs: Private equity / private credit ETFs, even more commoditised access to real assets, infrastructure, it may be possible to have hedge fund/type strategies disguised as an ETF, etc. An increasing demand for cameras is being met by regulation catching up, as well as the drive from engineers to improve technology.
  • Regulation & oversight: As passive investing increases, there may be more regulatory attention on index-constraining, concentration risk, disclosure, transparency of the rules for ETFs, and any impact that flows might have on the stability of the markets. Also, performance, tax rules, and other structural issues may be under review.
  • Consumer education: Investors will need additional tools to understand overlap, risk, fees, etc. Investors will need to avoid pitfalls such as overconcentration. Platforms, fintechs, and advisers will invest more in the tools they develop for users to compare the costs and exposures of different ETFs.
  • Innovation in structure: Tax treatment will likely improve, costs will decrease, we will see new ETF wrappers or share class structures, and perhaps more ETFs with dynamic/fluid exposures (but still transparent and low cost).

Final verdict: Is passive the dominant future?

Yes – for many investors, passive investing through ETFs is the direction that the U.S. market is moving. The trend is more than strong, like, structural. ETFs and index-based strategies offer attractive benefits for a wide range of investors – low cost, transparency, ease of access and the tax advantage of trading.


But passive is not perfect, for those investors who require niche exposure, wish to access risk management in the unusual situation of the market or think of alpha generation through individual securities or sectors, there continues to be a place for active management. Asset Allocation: The likely future will be dual passive core/active sleeve + passive for most assets + tactical active tilts. For everyday Americans, a thoughtful passive ETF core makes a lot of sense to be the basis of long-term portfolios.
