Premiums,discounts and feedback trading: Evidence from emerging markets' ETFs

This study investigates the extent to which ETFs' premiums and discounts motivate feedback trading in emerging markets' ETFs. Using a sample of the first-ever launched broad-index ETFs from four emerging markets (Brazil, India, South Africa and South Korea), we produce evidence denoting that feedback trading grows in significance in the presence of lagged premiums. The significance of feedback trading becomes more widespread across our sample's ETFs as the lagged premiums grow in magnitude, with evidence also suggesting that the effect of lagged premiums over feedback trading varies prior to and after the outbreak of the recent global financial crisis.     

Premiums and discounts in ETFs: An analysis of the arbitrage mechanism in domestic and international funds

We study premiums/discounts associated with ETFs using the Ornstein–Uhlenbeck process augmented with jumps. Our results confirm the high efficiency of the ETFs' arbitrage pricing mechanism. The median long-term mean premium of U.S. equity ETFs is zero. International equity ETFs and bond ETFs face more barriers to arbitrage, which results in higher long-term mean premiums and lower speeds of adjustment. Enhancing the mean-reverting process with jumps improves the model fit. The probability of jumps is the highest for international equity ETFs.     

The pricing and performance of leveraged exchange-traded funds

Leveraged ETFs are a recent and very successful financial innovation. They provide daily returns that are in a multiple or a negative multiple of the daily returns on a market benchmark. In this paper, we examine the characteristics, trading statistics, pricing efficiency and tracking errors of a sample of leveraged ETFs. We find that these ETFs are traded mainly by retail traders with very short holding periods. Price deviations (from NAV) are small on average, but large premiums and discounts are prone to occur. More interestingly, the behavior of premiums is different between bull (i.e., those with a positive multiple) and bear ETFs (i.e., those with a negative multiple). Our findings are consistent with the argument that the end-of-day rebalancing of the funds’ exposures increases market volatility at the close of a trading day. As for tracking errors, they are small for holding periods of up to a week, but become increasingly larger for longer horizons.     

Information-based trading and information propagation: Evidence from the exchange traded fund market

This paper studies the information-based trading of exchange-traded funds (ETFs) and the information propagation from the ETF market to its index. We find that the ETF trading triggered by asymmetric information and belief heterogeneity not only accelerates the ETFs' price discovery process but also increases the flow of information to the tracked index. Moreover, the price efficiency of the index also improves along with these two types of trading and their efficiency effects can be further enhanced by a speedier ETFs' price discovery. These observations portray the mechanism of the inter-market information propagation.     

Overreaction of country ETFs to US market returns: Intraday vs. daily horizons and the role of synchronized trading

In this paper we study the intraday price formation process of country Exchange Traded Funds (ETFs). We identify specific parts of the US trading day during which Net Asset Values (NAVs), currency rates, premiums and discounts, and the S&P 500 index have special effects on ETF prices, and characterize a special intraday and overnight updating structure between these variables and country ETF prices. Our findings suggest a structural difference between synchronized and non-synchronized trading hours. While during synchronized trading hours ETF prices are mostly driven by their NAV returns, during non-synchronized trading hours the S&P 500 index has a dominant effect. This effect also exceeds the one that the S&P 500 index has on the underlying foreign indices and suggests an overreaction to US market returns when foreign markets are closed.     

The information content of closed-end country fund discounts

This paper examines whether premiums and discounts on closed-end country mutual funds (CECFs) contain useful information about future returns. We find that higher CECF premiums are associated both with higher future returns on the relevant foreign market index and with higher future NAV returns after controlling for the foreign market return. CECFs trading at large discounts are not necessarily bargains, because their future NAV performance can be expected to be relatively poor.     

From dusk till dawn (and vice versa): Overnight-versus-daytime reversals and feedback trading

Although overnight-versus-daytime return reversals have often been ascribed to the heterogeneous clienteles of the overnight and daytime sessions, there exists no evidence to date on how those clienteles' trading behaviour motivates these reversals. We empirically investigate this issue for the first time by assessing whether these reversals are the result of feedback trading during overnight/daytime hours. Drawing on the S&P 500 ETF for the 1993–2021 period, we find that overnight (daytime) feedback trading largely motivates the expected positive (negative) overnight (daytime) returns; in line with this, days entailing the expected negative overnight-versus-daytime return reversals accommodate stronger feedback trading at the daily (i.e., close-to-close) frequency. Daytime feedback trading is present when the immediately preceding overnight session's returns are positive, while overnight feedback trading reveals a strong Monday-effect. We also show that overnight-versus-daytime variations of feedback trading hold across other large US ETFs.     

EXPLAINING PREMIUMS AND DISCOUNTS ON CLOSED-END EQUALITY COUNTRY FUNDS

Over the past decade or so, the surge of interest among U.S. investors in international investing has led to the creation of numerous foreign equity country funds. Like U.S. closed-end mutual funds, the prices of such closed-end country funds fluctuate widely in relation to their underlying net asset values (NAVs).
In this paper, the authors summarize the major findings of their recent study of the performance of 28 country funds relative to their NAVs over the period 1978–1995. While 20 of the 28 funds traded at average discounts to their net asset values, the discounts for the country funds were smaller than those of the average U.S. fund, and over a quarter of the funds sold at premiums.
In an attempt to explain such premiums or discounts, the authors examined primarily three factors: (1) the sensitivity of country-fund returns (relative to that of local market indices) to U.S. returns; (2) the possible effects of local government investment restrictions; and (3) the impact of exchange rate changes. Although most of the eight funds that traded at average premiums represented countries with significant restrictions on capital flows and foreign ownership, there were also a number of funds with similar restrictions trading at significant discounts. In exploring the reasons for such discounts, the authors noted that the returns to the country funds were "surprisingly sensitive" to U.S. market conditions, thus reducing the extent of their diversification benefits for U.S. investors. The article also raises the possibility that if such country funds are not "priced at the margin" by globally diversified investors, U.S investors' "country-risk sentiments" could cause such funds to trade at discounts.     

ETF Premiums and Liquidity Segmentation

Exchange traded funds (ETFs) provide a means for investors to access assets indirectly that may be accessible at a high cost otherwise. I show that liquidity segmentation can explain the tendency for ETFs to trade at a premium to net asset value (NAV) as well as the life‐cycle pattern in premiums. ETFs with larger NAV tracking error standard deviations (TESDs) tend to trade at higher premiums and the liquidity benefits offered by foreign ETFs and fixed income ETFs are revealed to be the most valuable to investors. Further tests validate that TESD has the desirable properties of a liquidity segmentation measure.     

FOREIGN OWNERSHIP RESTRICTIONS AND MARKET SEGMENTATION IN CHINA'S STOCK MARKETS

We study market segmentation in China's stock markets, in which local firms issue two classes of shares: class A shares available only to Chinese citizens and class B shares available only to foreign citizens. Significant stock price discounts are documented for class B shares. We find that the price difference is primarily due to illiquid B‐share markets. Relatively illiquid B‐share stocks have a higher expected return and are priced lower to compensate investors for increased trading costs. However, between the two classes of shares, B‐share prices tend to move more closely with market fundamentals than do A‐share prices. Therefore, we find A‐share premiums rather than B‐share discounts in China's markets. JEL classification: G15     

Exchange‐Traded Fund Introductions and Closed‐End Fund Discounts and Volume

Exchange‐traded funds (ETFs), like closed‐end funds (CEFs), are managed portfolios traded like individual stocks. We hypothesize that the introduction of an ETF in an asset class similar to an existing CEF results in a substitution effect that reduces the value of the CEF's shares relative to that of its underlying assets. Our event studies show that upon the introduction of a similar ETF, CEF discounts widen significantly and relative volume declines significantly. Single‐equation and systems estimation models show that the widening in discounts and reduction in volume are related to returns‐based measures of the substitutability of ETFs for CEFs.     

Does ETF trading affect the efficiency of the underlying index?

This study finds that both contemporaneous and lagged ETF trading volumes in both absolute and relative terms are significant contributors to the price efficiency of the underlying index. The variation in ETF shares outstanding is also positively associated with the index efficiency but it weakens the effect of ETF trading on the index efficiency. Moreover, the synthetic ETF price dominates the index in information share and the dominance increases in ETF trading. However, the relation between an individual ETF's information share and its trading volume varies, which is significantly positive for the leading ETF but ambiguous for other ETFs.     

Japan and Hong Kong Exchange-Traded Funds (ETFs): Discounts, Returns, and Trading Strategies

Foreign exchange-traded funds (ETFs) trade on U.S. exchanges but provide broad exposure to foreign markets. ETFs are designed to minimize the deviation between price and value of the underlying securities. However, nonoverlapping trading hours between the United States and many foreign markets inhibit this mechanism. The data for Japan and Hong Kong iShares show that deviations exist between the ETF price and the value of the underlying securities. The deviations are positively related to subsequent ETF returns creating potential profit opportunities. A simple trading rule based on this observation produces impressive gross returns when compared to a buy-and-hold strategy.     

Intraday patterns in London listed Exchange Traded Funds

In this paper we examine the intraday trading patterns of Exchange Traded Funds (ETFs) listed on the London Stock Exchange. ETFs have been shown to be characterised by much lower bid–ask spread costs and by lower levels of information asymmetry than individual securities. One possible explanation for intraday trading patterns is that concentration of trading arises at the start of the trading day because informed traders have private information that quickly diminishes in value as trading progresses. Since ETFs have lower trading costs and lower levels of information asymmetry we would expect these securities to display less pronounced intraday patterns than individual securities. We fail to find that ETFs are characterised by concentrated trading bouts during the day and therefore find support for the argument that information asymmetry is the cause of intraday volume patterns in stock markets. We find that ETF bid–ask spreads and volatility are elevated at the open but not at the close. This lends support to the “accumulation of information” explanation that sees high spreads and volatility at the open as a consequence of information accumulating during a market closure and impacting on the market when it next opens.     

The effect of liquidity and arbitrage on the price efficiency of Chinese ETFs

We study the potential factors that determine the large and persistent price deviations in Chinese equity exchange-traded funds (ETFs). Our results suggest that ETF liquidity and arbitrage activity are positively correlated with ETF price efficiency, and the relation is more pronounced with higher institutional ownership. We also evaluate the effect of two exogenous shocks in the Chinese market. Using a policy change that added market makers to ETFs on the Shenzhen Stock Exchange (SZSE) and Shanghai Stock Exchange (SSE), we find that market makers improve price efficiency and that the impact is stronger for ETFs with lower liquidity. We also exploit a change in trading rules on the SZSE and show that the relaxation of arbitrage restrictions improves price efficiency. Altogether, these findings provide evidence that lack of liquidity, due to the unique market structure and regulations of the Chinese market, contributes to price inefficiency of Chinese ETFs.     

Differently motivated exchange traded fund trading activities and the volatility of the underlying index

This paper examines the correlations between two types of a market index's volatility and three trading motives of the index's exchange traded funds (ETFs). We find that ETF trading driven by belief dispersion is highly correlated with both the variance in efficient price innovations (VEPI) and the index's total volatility. Privately informed ETF trading is closely connected to the VEPI but not the total volatility, while liquidity ETF trading explains the total volatility but has little power in explaining the VEPI. Moreover, the leading ETF dominates smaller ETFs in explaining both types of volatility and often has more explanatory power than control variables.     

Can Diversification Create Value? Evidence from the Electric Utility Industry

Despite SEC and state-level resistance, and contrary to the trend pursued by other firms, many electric utilities have diversified into non-electric and unregulated businesses. Moreover, this failure to focus has been rewarded with higher firm values, again contrary to the discounts documented in the literature for other diversifying firms. Prior literature has questioned whether these premiums (or discounts) can be attributed to diversification per se. Rather, these premiums could arise from the characteristics of the diversifying firms, which have then endogenously chosen to diversify. In a new approach, where regulation can make the diversification decision largely exogenous, we examine the investment policies of the comparable electric-segments in the diversifying and non-diversifying utilities. We find that single-segment electric utilities over-invest compared to diversifying utilities, which explains their diversification premiums and implies that diversification can create value by opening up new investment opportunities.     

Future Events—A Conceptual Study of their Significance for Recognition and Measurement A Review Article

A number of research papers present evidence of fee premiums paid to specialist auditors. In this paper, we explore for listed and unlisted New Zealand firms not only the question of whether such premiums exist, but perhaps more importantly why they exist. We find evidence of fee premiums for auditor specialisation defined at the city level but not at the national level. We extend testing to examine the issue of self-selection of auditors by clients; we examine several different industry classification schemes and a number of different specialisation measures; and we consider the issue of portfolio specialists. We find from these additional tests that self-selection does not account for the existence of specialisation premiums; various alternative classification schemes all result in premiums at the city level; and portfolio specialists also earn fee premiums when portfolio specialisation is measured at the city level. We find that these specialist premiums apply most consistently to larger client firms and to low-risk firms. We consider various explanations and conclude that this result is consistent with non-specialist auditors providing discounts to attract desirable clients. Desirable clients – those that are large or low risk – are not able to negotiate fees as successfully with auditors who have differentiated themselves via industry specialisation.     

Do pricing efficiencies in Indian equity ETF market impact its performance?

We examine the pricing efficiency of domestic exchange-traded funds (ETFs) in the Indian equity market where growth co-exists with operating inefficiencies. The ETFs, on average, outperform their fund benchmarks, but the magnitudes of the premium (discount) and tracking error are considerably higher for a synchronously traded market. Among the ETF categories based on fund benchmarks, thematic and broad market ETFs have higher tracking errors and discounts than strategy and sectoral ETFs. We find a nonsignificant negative relationship between discount and redemption units, implying that the creation/redemption process remains unaffected by the prevailing discount in the market. Despite low arbitrage constraints, market participants fail to curtail the prevailing tracking error and discount. This study highlights the operational constraints of arbitrageurs in the Indian ETF market.     

On the premiums of iShares

We show that the newly developed exchange-traded world equity index funds, or iShares, trade at economically significant premiums for 10–50% of the times even after controlling for transaction costs and time-zone measurement errors. Moreover, iShares price returns exhibit excessive volatility relative to their NAV returns. These findings suggest a limit of arbitrage in the international iShares market where iShares can be created and redeemed at will and premiums that exceed the creation/redemption transaction costs should be immediately arbitraged away. However, our cointegration and persistence profile analyses indicate that the deviations of most iShares' prices from their NAVs are not persistent and converge to zero within two days. We propose several rational factors to explain the absolute value of iShares premiums. The panel regression results suggest that institutional ownership, bid–ask spread, trading volume, exchange rate volatility, political and financial crises and, to a lesser extent, the conditional correlation between the U.S. and home markets are the significant driving factors of the size of iShares premiums. However, a significant variation of the premiums still remains unexplained, which suggests that behavioral factors may account for some mispricing.
