The purpose of this paper is to provide a brief review of three strands of the literature on exchange‐traded funds.

The paper starts with a review of the history of the growth of exchange‐traded funds and their characteristics. The paper then examines the key factors and findings of the existing studies on, respectively, the pricing efficiency, the tracking ability/performance, and the impact on underlying securities of exchange‐traded funds.

Although there has been a substantial amount of research conducted to advance our knowledge on the trading, management, and effect of exchange‐traded funds, the findings are still far from conclusive in addressing a number of research questions.

Investors and other market participants will find this review informative in enhancing the understanding of exchange‐traded funds.

By highlighting the general theme of the related research findings, the paper provides a systematic review of the existing literature that future researchers can utilize in developing their research agenda.

This chapter examines the current state of crypto exchange-traded funds (ETFs). It focuses on issues preventing wider implementation and specific products. ETFs have become a popular investment vehicle that investors use to help achieve their long-term goals. A recurring theme is that regulators protect individual investors from direct exposure to cryptocurrency, which many view as highly speculative investments. Pressure from institutions and investors for a bitcoin-based ETF made progress in 2021 when Proshares, an ETF specialized investment company, debuted the first-ever bitcoin futures ETF in the United States. This event is the first-time investors could buy a fund on the New York Stock Exchange that tracks derivative futures contracts of bitcoin. This occurrence pushed this digital asset’s spot price to all-time highs, serving as a breakthrough in cryptocurrency history.

The authors examine the factors that impact the growth of exchange traded funds (ETFs) from 1990 to 2020. The authors show the first-mover and winner-takes-all effects from top ETF issuers. Besides the longer history and larger asset under management (AUM), the ETFs being managed by top issuers have exhibited lower risks and higher trading volume. Delisted ETFs on the contrary has a shorter history, lower AUM, higher risks, and lower trading volume. For zombie ETFs, the authors find longer history, lower risks but lower AUM and trading volume, controlled for total expense ratio, return, volatility, Amihud (2002) illiquidity, bid-ask spread, turnover ratio, as well as year, issuer, asset class and region fixed effects. The authors further study the ETFs’ AUM and trading activities over the 2008 Global Financial Crisis (GFC) and COVID-19 pandemic crisis, and find that the GFC has a significant negative impact while the COVID-19 has a positive impact on the ETFs’ popularity. The significant increase in AUM of ETF relative to common stocks during the COVID-19 is associated with retail investors’ holdings, as the authors document a significant reduction of institutional holdings at the aggregate level.

To discuss how product innovations in exchange‐traded funds (ETFs) have blurred the line between passive and active management, and to explore the legal ramifications of these developments.

Describes how ETFs operate and how the ETF marketplace has grown; discusses the use of broad‐based indexes for most ETFs until recently; describes newer ETFs that provide targeted exposure to narrow market segments; and discusses underlying indexes that are based on performance‐based characteristics rather than market segments, along with possible difficulties in making performance‐based criteria widely available to investors.

Historically the SEC has expressed skepticism over actively managed ETFs because of uncertainty as to whether they can provide the same portfolio transparency and arbitrage opportunity that traditional ETFs can. As “Rule Sets,” or criteria for including companies in performance indexes, become more involved and less objective, the challenge will be to ensure that sufficient arbitrage opportunities exist to ensure pricing efficiency. If that challenge can be met, it may serve as a model for a truly actively managed ETF.

Explains how the new generation of ETFs is coming closer to the line of active management and the legal issues that must be surmounted before truly actively managed ETFs are offered.

The paper aims to determine if a country's Economic Freedom Index value has any relationship to the return of the related country specific exchange traded fund.

A total of 36 country specific exchange traded funds were selected for use in this study. The historical returns for 2011, the three‐year period ending in 2011, and the five‐year period ending in 2011 were recorded if available for each exchange traded fund. Each exchange traded fund (ETF) was placed into one of four groups based upon its country's overall Economic Freedom Index value. The range of Economic Index values for each group was the same ones used by the publishers of the Economic Freedom Index. The mean ETF return and standard deviation for 2011, three‐year, and five‐year periods were calculated for each of the four groups. The mean/standard deviation of the Economic Freedom Index and each of its components for 2011, the mean of the three‐year period, and the mean of the five‐year period were calculated for each of the four groups. The degree of statistical significance between the mean returns of the four groups was determined by using ANOVA. The correlation coefficients and the degree of statistical significance were calculated between each component of the index, between each component and the overall index value, and between the overall index value and the ETF returns.

The correlations between the components of the Economic Freedom Index generally tend to be positive and statistically significant. The correlations between the components of the Economic Freedom Index and the Economic Freedom Index tend to be positive and statistically significant. The correlation between the mean ETF returns of the various groups and the value of the mean Economic Freedom Index tends to be mixed. There appears to be no statistical significance of the difference between the mean ETF returns of each group and the mean overall score of the Economic Freedom Index for that group. For the year 2011 the level of significance was 0.103, for the three‐year period the level of significance was 0.541, and for the five‐year period the level of significance was 0.132. The differences within each group are more than the differences between the groups. The value of the Economic Freedom Index does not appear to correlate with the return of the country specific exchange traded fund.

The paper relates a country's environment for conducting business as represented by its Economic Freedom Index to the equity returns of firms in that country. The results of this study would be of interest to those individuals or institutions making investment decisions regarding country specific exchange traded funds. If a positive correlation exists between the index value and the return of the exchange traded fund, this information could improve the prediction of country specific exchange traded fund returns.

Exchange traded funds (ETFs) are one of the most innovative financial products listed on exchanges. As reflected by the size of the market, they have become popular among both retail and institutional investors. The original ETFs were simple and easy to understand; however, recent products, such as leveraged, inverse, and synthetic ETFs, are more complex and have additional dimensions of risk. The additional risks, complexity, and reduced transparency have resulted in heightened attention by regulators. This chapter aims to increase understanding of how ETFs function in the market and can potentially impact financial stability and market volatility.

We discuss the evolution of ETFs, growing regulatory concerns, and the various responses to these concerns.

We find that concerns related to systemic risk and excess volatility, suitability for retail investors, lack of transparency and liquidity, securities lending and counterparty exposure are being addressed by both market participants and policy makers. There has been a shift toward multiple counterparties, overcollateralization, disclosure of collateral holdings and index holdings.

The analysis contained in this chapter provides an understanding of the role of ETFs in the financial markets and the global economy that should be valuable to market participants, investors, and policy makers.

The purpose of this study is to identify the factors that impact the exchange-traded funds net fund flow changes on a daily basis.

A total of 1,212 different exchange-traded funds with a proprietary daily net fund flow data and logistic regressions were studied because the majority of the 1,212 exchange-traded funds have mostly zero daily net fund flow changes.

It was documented that in the period December 22, 2005 to July 28, 2010 autocorrelation at the daily frequency is not universally present for the 1,212 exchange-traded funds that we study, despite the fact that this is the case in the monthly data documented in prior studies. No support was found for the feedback trading hypothesis but some support was found for the contrarian investor hypothesis on daily basis, even though the opposite is ascertained for both in the prior literature monthly data. Also, it cannot be concluded that tracking error prompts net fund flow changes and thus arbitrage activity.

The paper contributes to the ongoing analysis of the factors influencing investment companies fund flow changes, which has mostly focused on open-end funds and monthly data so far. Considering the increased scope and relevance of exchange-traded funds in today’s financial markets, this study fills a void in the fund flow changes literature.

The purpose of this paper is to consider the implicit effect of the underlying foreign currency exposure on the performance characteristics of country exchange traded funds.

To arrive at an overall estimation of the exchange-traded fund (ETF)’s tracking error, the mean of the three measures of tracking error was calculated for both the hedged (r_LC) and unhedged (r_NAV) return series. Since tracking error does not capture all the risk inherent in a country index fund, the study extends the analysis using the Sortino and Modified Sharpe ratios.

The decision to hedge currency risk should not be taken on the sole basis of historical volatilities. The investor must also factor in transactions costs, the possible roll of futures contracts and prevailing interest rate differentials. If the rate on the foreign currency is greater than the dollar (euro) rate, the investor will pay for the hedge. If the rate on the foreign currency is less than the dollar (euro) rate, the investor will gain on the trade. Given that hedging entails additional costs, in cases where the neutralization of currency volatility only reduces risk modestly, it would be advisable to leave the exchange rate risk unhedged. We propose two metrics for ETF investors deciding whether to hedge a country ETF’s underlying currency risk.

The results highlight a key finding: while the majority of country funds accurately track the performance of the underlying foreign index when measured in the local currency, returns in the fund currency can be much more volatile. In breaking down the sources of country fund volatility, the paper demonstrates the impact of the underlying currency movements on overall fund risk. In cases where the currency impact has a significant impact on fund tracking errors, an index-oriented investor benefits from neutralizing the exchange rate effect. Additionally, as the Sortino and Modified Sharpe measures suggest that the underlying currency exposure offers in most cases a better risk-adjusted return for country exchange-traded funds (ETFs) in the listing currency, we also calculate the risk minimizing foreign currency exposure for each fund and propose a decision rule based on the net currency variance to decide whether to hedge the ETF’s currency risk. The optimal hedge ratio indicates that US-based investors should only partially hedge the underlying currency risk while European-based investors are better off fully hedging currency risk.

The purpose is of this paper is to investigate whether the tracking ability of exchange traded funds (ETFs) is lower in highly volatile periods, and to shed more light on the factors behind the tracking error.

The authors apply the Error Correction Model that incorporates a short‐run adjustment mechanism on domestic US ETFs that follow industrial indices.

It was found that tracking errors attained pronounced levels during 2008 compared to 2006 and 2007, mainly in ETFs from the real estate and banking and finance sectors. In addition, tracking error is positively correlated with the daily volatility of the ETF, while trading volume has a limited effect on reducing tracking errors.

The paper sheds more light on the relationship between securities and their fundamentals, and contributes to the literature on the information transmission mechanism for dually‐listed securities.

The paper uses the co‐integration tests and the error correction model (ECM) to test the long‐run relationship between returns on domestic exchange trade funds (ETFs) and the returns on the underlying indices. In particular, the ECM is used for ETFs for the first time.
