Active ETFs account for a much larger share of ETF traded dollar volume than their share of aggregate ETF asset value, suggesting they are more actively traded by investors than their passive counterparts. For example, Very Active ETFs account for as much as 86% of the dollar volume of ETFs traded in the secondary market, which is twice their share of aggregate ETF assets. Thus, aggressive–passive ETFs are active not only in their holdings, due to active decisions made by the fund manager or index provider (active in form), but also in the way they are used by investors who frequently trade in and out of active ETFs (active in function). ETFs can also be inputs in more complex trading strategies, particularly by institutional investors. Huang, O’Hara, and Zhong (2021) investigate industry ETFs, focusing on their role as hedging vehicles.
If not, they cannot adequately substitute for funds that invariably deliver what the tin promises. For example, Bank of America found that nearly half of U.S. large-cap equity fund managers outperformed their benchmarks in 2017, the best rate since 2009. Keeping an eye on these trends — this is one area where advisers can help — can be the determining factor in what kind of approach you take for a specific asset in your portfolio. Passive investing has increased in popularity with robo-advisors, such as Acorns, Wealthfront, and SoFi, which offer affordable, beginner-friendly interfaces for retail investors to access the market and learn about investing. Active investing is still popular among advanced traders seeking big returns on larger, riskier investments. Robo-advisors are low-cost, beginner-friendly investment platforms that invest your funds in passively managed stocks, ETFs, and index funds.
Active Investing and Passive Investing
Passive investing (aka passive management) is a low-cost, long-term investing strategy aimed at matching and growing with the market, rather than trying to outperform it. With passive investing, you must ignore the daily fluctuation of the stock market. For example, at a sector level some sectors may have great performance, others poor returns, so aggregating may obscure these differences. Even within size and style categories, aggregation may miss the activeness resulting from factor timing/ factor rotation strategies used by active in function ETFs. We use the latest available version of these tables, which include links through to the end of 2016 (see Cao et al., 2017). We adjust the holdings data to account for funds that have multiple share classes similar to Ben-David, Franzoni, and Moussawi (2018).25 Where holdings data are missing or incomplete, we supplement them with holdings data from the ETF Global database, where we also obtain fund fees.
Interestingly, the outflows are from the Very Active and Moderately Active mutual funds. In fact, the only mutual funds to receive positive inflows are the Moderately Passive and Very Passive ones, consistent with the technology-induced fall in operating costs attracting more investor funds. These passive mutual fund inflows, however, are smaller than the inflows to the ETF passive products, perhaps reflecting a lower overall cost structure of passive ETFs, or perhaps greater ancillary revenue accruing to ETFs.
Here we exploit this relation to make quantitative statements about the former based on observations of the latter. The search cost depends on the number of informed managers M and the number of active investors I, so we need to consider how many managers become informed in equilibrium. To understand why investors may choose to use asset managers, note first that an investor with a higher cost (dl) of self-directed investing than the passive manager’s marginal cost (kp) clearly benefits from outsourcing any passive portfolio construction to the manager. Further, investors with active managers can benefit from both potential low marginal costs from the manager (ka) and, importantly, the fact that the active manager can effectively share the fixed cost of information (k) across all his investors. On the other hand, an investor with very low cost of self-directed investing may be best off investing himself. The idea, known as “Samuelson’s dictum,” is that active investors have stronger incentives to correct (micro) inefficiencies in relative prices than to correct the overall (macro) price level.
Community Investment For Main Street
Hence, this model cannot explain the finding of Cremers et al. (2016) discussed above, namely, that the size and performance of active management move in opposite directions (but the model can explain a number of other phenomena). This figure shows properties of the model implied by different values of the percentage cost of passive investment, fp% (on the x-axis, in percent). Panel A shows the total inefficiency (η), the macro-inefficiency (ηβ), and the active fee (fa%), all in percent.
The risky assets deliver final payoffs given by the vector v, which is normally distributed with mean v¯ and variance-covariance matrix Σv, which we write as v∼N(v¯,Σv). The choice between an active or passive investment strategy is a personal one, with unique advantages and disadvantages. Our research helps advisors to guide their clients around incorporating elements of both into their portfolios. Despite the fact that they put a lot of effort into it, the vast majority of of active fund managers underperform the market benchmark they’re trying to beat.
They show that hedge funds use industry ETFs in a “long the stock, short the ETF” strategy, essentially using the ETF to hedge out industry risk from their underlying long positions in individual stocks. An interesting finding of that paper is that hedge funds trade more aggressively when they can use an industry ETF to hedge, which in turn allows information to be incorporated more quickly into asset prices. Far from playing a passive role, ETFs now function directly and indirectly as active investment products. Section 2 sets out why activeness matters, provides a framework for viewing investment products along a continuum of passive to active, and defines the concepts of active in form and active in function. Section 3 defines empirical measures of ETF activeness and characterizes the ETF activeness landscape.

Our model also predicts that the fund flow–performance relation should differ between these active and passive investment products, with passive products having little or no fund flow sensitivity unlike active funds that will (Hypotheses 3 and 5). When the cost of information k decreases, overall asset price inefficiency η decreases and the what is one downside of active investing macro-inefficiency ηβv decreases by more than the total micro-inefficiency (η−ηβv) as long as n is not too small. Further, the number of self-directed investors remains unchanged, the numbers of active investors I and of informed active managers M increase, the active management fee fa decreases, and the passive fee fp is unchanged.
The standard APT describes expected returns in the presence of a factor structure, and we show that our factor structure is scaled in a way that is consistent with an APT equilibrium with many assets. The more novel part of the proposition is a related APT result for market inefficiency. To understand the APT for efficiency, recall that the inefficiency ηζ of any set of portfolios ζ is always less than or equal to overall market inefficiency, η. Over the past half century, financial markets have witnessed a continual rise of delegated asset management and, especially over the past decade, a marked rise of passive management, as seen in Figure 1. Actively managed investments charge larger fees to pay for the extensive research and analysis required to beat index returns.
In other words, most of those who opt for passive investing believe that the Efficient Market Hypothesis (EMH) to be true to some extent. Morningstar was almost 20 years away from awarding its Morningstar Analyst Ratings. Had the company produced those reports in 1992, perhaps its analysts would have spotted both Primecap’s potential and U.S.
Panel B shows the fractions of ownership allocated to passive management (Sp, upper area in the figure), active management (I, middle area), and self-directed investment (bottom area). Next, we consider what happens to macro- and micro-efficiency when the number of assets, n, is large. Indeed, thousands of securities exist in the real world, so we may achieve a tractable approximation of the real world by considering the simplifications that arise when we let n go to infinity. Further, the tractability afforded by looking at this large-asset limit also allows us to consider a more general factor structure with multiple factors, similar to the setting of the Ross (1976) arbitrage pricing theory (APT). Hence, we can study the pricing of risk and market efficiency when active investors can diversify across idiosyncratic risks. We see that the optimal uninformed portfolio can indeed be linked to the conditional expected market portfolio, E(q|p).
With so many pros swinging and missing, many individual investors have opted for passive investment funds made up of a preset index of stocks or other securities. Passive investing and active investing are two contrasting strategies for putting your money to work in markets. Both gauge their success against common benchmarks like the S&P 500—but active investing generally looks to beat the benchmark whereas passive investing aims to duplicate its performance.
What is Active Investing?
Cremers and Petajisto (2009) propose a measure of activeness for mutual funds based on how far a fund departs from its benchmark. Pastor, Stambaugh, and Taylor (2020) suggest an alternative measure for mutual fund activeness which incorporates the portfolio’s liquidity and diversification. Each of these measures is designed to capture specific features of activeness, particularly as it relates to standard active management behavior. This functional approach to investment management recognizes that the greater liquidity, low transaction fees, and tax efficiency of ETFs provide new building blocks for implementing investment strategies. What matters in this context is the exposure that can be obtained with a particular ETF and its contribution to the investor’s total portfolio, not the particular properties it has as a stand-alone investment.
- Our model yields five hypotheses predicting how passive ETFs, aggressive–passive ETFs, and active mutual funds should differ.
- Estimates of future performance are based on assumptions that may not be realized.
- This approach requires a long-term mindset that disregards the market’s daily fluctuations.
- Ascribing causality for changes in market fundamentals to the effects of ETFs is not our intention.

If your top priority as an investor is to reduce your fees and trading costs, period, an all-passive portfolio might make sense for you. In our experience, investors tend to care more about factors like risk, return and liquidity than they do fees, so we believe that a mixed approach may be beneficial for all investors—conservative and aggressive alike. Investors with both active and passive holdings can use active portfolios to hedge against downswings in a passively managed portfolio during https://www.xcritical.com/ a bull market. SPIVA can help investors make informed decisions about whether to use an active manager or invest in an index-based fund such as an ETF. It also reminds investors that using past performance as the main guidance in fund selection could be misleading due to the lack of performance persistence among actively managed equity funds. Active investing attempts to benefit from short-term price fluctuations by implementing active trading strategies like short-selling and hedging.
