Pricing inefficiencies and feedback trading: Evidence from country ETFs

In view of the established presence of wide deviations of US-listed country ETFs' prices from their net asset values, we study whether feedback trading exists in this category of ETFs and whether it varies with their premiums and discounts. Using a sample of nineteen country ETFs for the 2000–2019 window, we find that feedback trading is present in several of them, particularly those targeting Asia Pacific markets. Feedback trading varies with the sign (i.e., premiums and discounts), level, and nature (observed/forecast) of these deviations, as well as prior to and after the outbreak of the 2008 crisis. Of particular note is the widespread feedback trading reported across the vast majority of country ETFs on those days for which there exist successful predictions of premiums/discounts, a fact suggesting that country ETFs' premiums/discounts contain useful information as per their trading dynamics.     

Free ad(vice): internet influencers and disclosure regulation

Consumers rely on intermediaries (“influencers”) such as social media recommendations to provide information about products. The advice may be mixed with endorsement in a way that is unobservable to the follower, creating a trade‐off for influencers between the best advice and the most revenue. This article models the dynamic relationship between an influencer and a follower. The relationship evolves between periods of less and more revenue. The model can provide insight into policies such as the Federal Trade Commission's mandatory disclosure rules. An opt‐in policy may be superior: it deregulates influencers who are reaping the rewards of past good advice.     

More long-term care for better healthcare and vice versa: investigating the mortality effects of interactions between these public sectors

Public healthcare (HC) and long-term care (LTC) sectors coexist in several OECD countries. Economic interactions between these two sectors have been found to occur even in the absence of formal integrated care arrangements. We investigate whether and how interactions between the HC and LTC sectors impact mortality. We analyse data on English local authorities in 2014–15 and employ a sequence of cross-sectional econometric specifications based on instrumental variables to identify the effect that LTC expenditure has on mortality through its interactions with HC services, and vice versa. Our findings suggest that any effect of LTC expenditure on mortality is likely to run through the HC sector by allowing the latter to reallocate resources from less to more effective services. A 10 per cent increase in LTC expenditure per user can indirectly save, on average, about three lives per million individuals. In addition, on top of the known HC direct mortality effects, we find that investing an extra £42 million in the HC sector – equivalent to a 10 per cent increase in HC expenditure per capita for the average local authority – can decrease the use of LTC services, producing around £7.8 million of savings. These can generate mortality effects if invested in services having an impact on mortality.     

Index futures and positive feedback trading: evidence from major stock exchanges

This paper tests the hypothesis that the introduction of index futures has increased positive feedback trading in the spot markets of six industrialized nations. The analysis is based on a model that assumes two different groups of investors, i.e., risk averse expected utility maximizing investors and positive feedback traders. There is evidence consistent with positive feedback trading before the introduction of index futures across all markets under investigation. In the period following the introduction of index futures, there is no evidence supporting the hypothesis that positive feedback trading drives short-term dynamics of stock returns. The possibility that this is due to possible migration of feedback traders from the spot to the futures markets is also tested. The results show no evidence of positive feedback trading in the futures markets. Overall, the findings support the view that futures markets help stabilize the underlying spot markets by reducing the impact of feedback traders and thus attracting more rational investors who make the markets more informationally efficient and thus providing investors with superior ways of managing risk.     

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.     

Investor sentiment and feedback trading: Evidence from the exchange-traded fund markets

This paper extends the standard feedback trading model of Sentana and Wadhwani (1992) by allowing the demand for shares by feedback traders to depend on sentiment. Our empirical analysis of three largest Exchange-Traded Fund (ETF) contracts in the U.S. suggests that there is a significant positive feedback trading in these markets and the intensity of which is generally linked to investor sentiment. Specifically, the level of feedback trading tends to increase when investors are optimistic. In addition, we find that the influence of sentiment on feedback trading varies across market regimes. These results are consistent with the view that feedback trading activity is largely caused by the presence of sentiment-driven noise trading. Overall, the findings are important in understanding the role of sentiment in investment behaviour and market dynamics and are of direct relevance to the regulators and investors in ETF markets.     

(Un)skilled leveraged trading of retail investors

We study the trading behavior of retail investors in the market of leveraged bank-issued retail derivatives, which are designed to encourage excessive trading and speculation. We investigate whether retail investors have private information and benefit disproportionately or whether they gamble without private information. We answer this question along three dimensions: (i) profitability, (ii) news trading, and (iii) transaction costs. We distinguish between derivatives by the type of underlying (index vs. individual stocks). We find that raw returns are negative for derivatives with stocks as the underlying, and only partially positive for those with index as the underlying. Nevertheless, risk-adjusted returns show poor performance, with Sharpe ratios below 0.30. We show that retail investors are attracted by news, but do not have private information prior to news events.     

Noise trading in small markets: Evidence from Amman Stock Exchange (ASE)

This study aims to analyze the behavior of traders in Amman Stock Exchange (ASE):-firstly at the market level by analyzing the market return volatility, defining the time frame of this volatility, and classifying it as transitory volatility or a permanent volatility, Daily closing of Amman free float market index will be used to indicate the market return during the period from 1/1/1992 to 31/12/2015 where 5899 observations were obtained. Secondly at the firms level by selecting a sample of trading companies and interpreting the results through analyzing some important features of the companies, such as share price and ownership structure, Daily closing of share price of the selected companies will be used to indicate the return during the period from 1/1/2015 to 31/12/2015 where 240 observations were obtained for each company during this period.To achieve the goals of this study, the Variance ratio test, GARCH test, and CGARCH test will be used. The study highlighted an important result that the common culture of traders on ASE was Noise Trading; the significance of this finding was statistically proven at the confidence level of 1%.This study recommends the competent authorities to enact a slew of strict measures: the implementation of Capital Gains Tax in a bid to slash frequent selloffs and purchasing of noise traders and increasing the commission of brokers in return for completing selloffs and purchasing deals. The study also affirmed the necessity of intervening periodically to raise awareness of the negative impact of speculation including the instability, increasing the firm’s cost of capital and the damage to traders’ confidence in the stock markets.     

Entry, exit and trading profits: A look at the trading strategies of a proprietary trading team

We examine the behavior of a 15 strong proprietary stock trading team and show how consistent intraday trading profits were generated. The team, who worked for a large US direct access trading firm, executed over 96 thousand trades in 3 months in 2000. Profitable intraday trading occurred in an anonymous dealer capacity, on both long and short positions, especially when volume and price volatility were higher. The traders rapidly entered long (short) positions when the number of dealers and size become greater on the bid (offer) side of the spread. Profits were taken early against the trend.     

Cross-sectional seasonalities and seasonal reversals: Evidence from China

We are the first to comprehensively investigate cross-sectional seasonalities and seasonal reversals in the Chinese A-share market. Empirically, utilizing monthly data from January 1995 to December 2019, we provide new supporting evidence that there are seasonalities and seasonal reversals in the cross-section. Interestingly, the occurrence of seasonal reversals takes a longer time than that of the U.S. market. Next, we explore explanations for cross-sectional seasonalities. The tests based upon macroeconomic risk, mood beta, and limits of arbitrage suggest that seasonalities are likely driven by temporary mispricing. Finally, we construct seasonality and seasonal reversal factors to study the investment value of seasonalities. We find that these factors can significantly increase the monthly Sharpe ratio by up to 0.34 and capture incremental information in predicting future returns relative to other well-known factors.     

Endogenous informed trading in the presence of trading costs: Theory and evidence

The basic premise of the model we propose is that market frictions (trading costs) force traders with market-wide information to strategically choose which securities to trade in. We study the effect of recognizing trading costs on the choices of informed traders and the resulting statistical properties of security prices. Specifically, we show that (1) stocks with intermediate β's have the least informative prices, even though they are traded by the greatest number of informed traders; (2) for high β securities, the contemporaneous correlation of prices is close to the correlation in fundamental values; (3) a security with a higher β, higher volume of liquidity trading and lower idiosyncratic variance is more likely to lead another security. With market capitalization as a proxy for the level of liquidity trading, these specific predictions of the model on the lead–lag relationship are also shown to be strongly supported by the data.     

Return reversals in the bond market: Evidence and causes

The finance literature has shown that equity returns are predictable using past returns. This study extends that literature by examining bond return predictability. Using returns constructed from dealer bid prices, we find short- to intermediate-term reversals in investment grade corporate bond returns. These reversals are larger in the first half of the sample period and consistent with the predictions of dealer inventory cost models. This supports Jegadeesh and Titman’s [J. Financ. Intermed. 4 (1995) 116] assertion that daily, weekly, and monthly reversals in equity returns come from dealer inventory considerations, not behavioral biases. Finally, unlike equity returns, we find no evidence of momentum in bond returns.     

Bank provision reversals and income smoothing: A case study

Incentives for banks to achieve income targets have previously been identified as a strong motivation for income smoothing (IS). Extant literature captures bank IS indirectly via discretionary provision estimations. In turn, our study directly locates IS through loan loss provision reversals. Drawing from bounded rationality perspectives, we investigate a systemic European Bank from January 2006 to September 2017, with 15,931 unique loan portfolio-quarter observations, employing a frequency and machine learning analysis. Our empirical investigation reveals both the main incentives underlying provision reversals recognition and the reported income consequences of such reversals, in times of recession. In particular, we find that provision reversals are principally used to avoid negative reported income (i.e., net losses). There is also some evidence that provision reversals are used to avoid income decline compared to the previous quarter. Finally, we show an asymmetric pattern of provision reversals over time with an emphasis on the early recession years. Our study contributes to the efforts of policy makers (both banking and accounting regulators) to reduce opportunistic, income-increasing actions by bank executives in difficult times.     

Trading time and trading activity: evidence from extensions of the NYSE trading day

The New York Stock Exchange extended its trading hours by 30 min in 1974 and in 1985; the first extension resulting in a delayed close and the second in an early open. We find a shift in volume to the new period after each extension. Additionally, there is a larger increase in volume after the 1985 extension than after the 1974 extension. We argue that the second effect is explained by the first. The extension at the end of the day allows some investors to postpone their trades, which results in occasional information cancellation or discovery; this mutes the effect of the extension on volume. In contrast, the extension at the start of the day allows some investors to accelerate trades, which precludes information cancellation or discovery and its negative effect on volume. This explanation suggests that the effect of an extension on volume depends, at least in part, on its timing.     

From pit to electronic trading: Impact on price volatility of U.S. Treasury futures

This paper investigates the dynamics of price volatility and trading volume of 10-year U.S. Treasury note futures within the context of transition from pit to electronic trading. The analysis is conducted over four discernible phases of futures trading evolution: the pit-only phase, the leap to electronic trading, and the electronic trading dominant phase, which is divided further into two periods, the before and after the financial crisis of 2007/2009. Generalized autoregressive conditional heteroskedasticity with in-mean conditional variance and generalized error distribution parameterization (GARCH-M-GED) tests are conducted to examine the conditional volatility of total returns index as a function of trading volume. The empirical results show a consistently negative relationship between the trading volume and price volatility for all four analyzed phases. They also show decreasing leptokurtosis (except for the direct effects of the recent crisis), continuously high persistency in volatility, as well as a weakening impact of unexpected ARCH-type shocks during the most recent analyzed period. Overall, the shift to electronic trading entails a substantial increase in trading volume, but not in price volatility of Treasury futures.     

Insolvency law reform in Australia and Singapore: Directors' liability for insolvent trading and wrongful trading

This article compares reforms to directors' liability for insolvent trading in Singapore and in Australia. We analyse the law in these two countries because they are important Asia‐Pacific trading partners and their laws were originally largely the same—Singapore's law on insolvent trading reflected the law in Australia from the 1960s. However, the law in the two countries has now diverged substantially. The comparison of these two countries therefore represents an interesting case study in how countries differ in their approaches to balancing the competing interests evident in laws that impose personal liability on company directors for insolvent trading. Reform of the prohibition against insolvent trading was a focus of Australia's insolvency law reforms in 2017, which led to the introduction of a safe harbour for directors from liability. Singapore's omnibus insolvency law reforms of 2018–19 include amendments to update Singapore's fraudulent and insolvent trading provisions by introducing a concept of “wrongful trading.” The article finds that there are some areas of convergence between these two jurisdictions when it comes to debates about such provisions but concludes that the different contemporary legislative histories in Australia and Singapore have affected their approaches to reform. Reformers in both jurisdictions have attempted to find an appropriate balance between protecting creditors, discouraging director misconduct, and encouraging entrepreneurship and innovation; however, this comparison suggests that the weight that reformers place on creditor protection compared with the concern that excessive personal liability can make directors unduly risk‐averse is influenced by their existing legislative framework and experience of those laws. Although Australia has shifted away from a strict focus on creditor protection, to give directors more opportunities to engage in restructuring, Singapore's amendments may provide a more creditor‐friendly regime.     

Informed trading and the price impact of block trades: A high frequency trading analysis

Using high frequency data from the London Stock Exchange (LSE), we investigate the relationship between informed trading and the price impact of block trades on intraday and inter-day basis. Price impact of block trades is stronger during the first hour of trading; this is consistent with the hypothesis that information accumulates overnight during non-trading hours. Furthermore, private information is gradually incorporated into prices despite heightened trading frequency. Evidence suggests that informed traders exploit superior information across trading days, and stocks with lower transparency exhibit stronger information diffusion effects when traded in blocks, thus informed block trading facilitates price discovery.     

Centralised order books versus hybrid order books: A paired comparison of trading costs on NSC (Euronext Paris) and SETS (London Stock Exchange)

This article compares the cost of trading large capitalisation equities on the hybrid order-driven segment of the London Stock Exchange and the centralised electronic order book of Euronext. Using samples of stocks matched according to economic sector, free float capitalisation, and trading volume, our study shows that transaction costs are lower on the centralised order book than on the hybrid order book. The presence of dealers outside the electronic order book favours the frequency of large trades, but is associated with higher execution costs for all other trades and higher adverse selection and inventory costs inside the order book.
