The return to value in Asian stock markets

This paper investigates the returns to value strategies in four Asian stock markets: Hong Kong, Korea, Singapore and Taiwan. Hong Kong, Korea and Singapore exhibit value premia while Taiwan shows value discounts. The impact of firm characteristics on value premia differs across the four markets. The robustness tests indicate that the value premia are time-varying. They become greater in the post-crisis period across all four countries, indicating that high volatility during the crisis period did understate the value premia. The value strategy's excess return is sensitive to the sample selection rule and the firm size and liquidity effects. With tighter sample selection criteria, value premia tend to decline, which indicates that both the firm size effect and the liquidity effect are important sources of value premia. Unequal weighting assigned to financial variables in constructing the Average Price Rank (APR) based on the overall performance of single-variable approach does not necessarily improve the results.     

Further evidence of the influence of option expiration on the underlying common stock

Over the past decade there has been increasing research into the interaction among the securities options markets and other institutions. Of particular interest in the earliest research was the extent to which social efficiency is enhanced by the trading of puts and calls. Since it is now well established that market-spanning opportunities are more complete when options are available, recent research has been directed toward such issues as the informational efficiency of the options exchanges and the relationship between an option premium and the behavior of the underlying common stock. Of interest to us in this research is the latter issue. We find significant new evidence that in the final two days of trading prior to the expiration of an option series, the presence of options influences some underlying stock prices.     

Technology-investing countries and stock return predictability

For 77 technology-investing countries we test whether their stock market returns are predictable. We find that exchange rate returns and U.S. stock excess returns predict stock market returns for most countries in our sample, while crude oil and inflation predict returns of less than 40% of countries. While in out-of-sample tests the evidence of predictability declines, U.S. returns still beat the constant returns model for three-quarters of countries in our sample. A portfolio of all 77 countries offers a mean-variance investor annualized profits of between 5.7% and 8.0%, and profits are maximized when return forecasts are based on U.S. returns.     

Turnover and return in global stock markets

I study how growth affects liquidity of global stock exchanges and how liquidity determines cross-sectional returns on those stock exchange index portfolios. I measure portfolio liquidity by turnover ratio computed as value of shares traded over the market capitalization. I obtain data from FIBV, an association of global stock exchanges. In a multiple regression model for turnover ratio, I find age, size, type of exchange, competition for order flow, and growth rate to be significant determinants of portfolio liquidity; however, exchange- and time-specific effects are more appropriate for modeling portfolio liquidity. The time effects yield to three distinct regimes, while the exchange-specific effects are surrogates for the legal systems, English common law, and Civil laws of the countries. I estimate the parameters of a multiple regression model in a two-stage GLS framework in which index return is a function of turnover. The GLS method is preferable since a turnover ratio may have a non-stationary, random component. The significant determinants of index return are turnover and volatility, although some of the volatility effect may be a spillover from a January effect. Investors expect higher return from high turnover markets. However, the positive turnover expected return relation is true only in emerging markets; in developed markets expected return is a function of volatility. This result confirms existing empirical evidence that high turnover stock portfolios generate superior returns and further the sources and pricing of risk in emerging and developed markets are different.     

Foreign institutional investors and stock return comovement

We investigate whether foreign institutional investors facilitate firm-specific information flow in the global market. Specifically, using annual institutional ownership data from firms across 40 countries, we find that foreign institutional ownership is negatively associated with excess stock return comovement. Our results are more pronounced when foreign institutional investors originate from common-law countries and hold a large equity stake in invested firms; and when the invested firms are located in civil-law countries. Overall, the evidence suggests that foreign institutional investors from countries with strong investor protection play an important informational role in mitigating excess stock return comovement around the world.

The externalities of credit default swaps on stock return synchronicity

We examine the externality effect of customer firms’ credit default swap (CDS) trading on the stock price informativeness of supplier firms. Our empirical results show that firms with a high proportion of sales to CDS referenced customers tend to have more firm-specific embedded information in their stock prices and thus higher stock price informativeness, which is associated with a lower level of stock return synchronicity. We provide new evidence of CDS trading externality on equity market information environments along the supply chain.     

Dynamic return predictability in the Russian stock market

This paper explores whether the relevance of a conditional multifactor model and autocorrelation in predicting the Russian aggregate stock return fluctuates over time. The source of return predictability is shown to vary considerably with information flow. In general, predictability of the Russian stock market return is at a high level. Autocorrelation increases during periods of low information flow. During periods of high information, conditional exposure to the local market risk and changes in oil price influence the expected return on the Russian stock market. The lagged global stock market factor and currency returns have insignificant influence.     

Revisiting the risk/return relations in the Asian Pacific markets: New evidence from alternative models

This paper examines the risk/return relations in eleven Asian Pacific stock markets and explores if the 1997 Asian financial crisis significantly influenced market behavior in the region. We use a plain vanilla time-series regression approach as well as various GARCH models. Although results significantly vary across model specifications, the overall evidence from GARCH models supports a significantly positive risk/return relation in several markets but only prior to the Asian financial crisis. These results accord with Glosten et al. (1993) and Harvey (2001) and suggest that the relative risk aversion is sensitive to both model specifications and structural breaks.     

Volatility transmission in regional Asian stock markets

This study aims to investigate the presence of volatility transmission among regional equity markets of Pakistan, China, India, and Sri Lanka. Moreover for developed countries, the stock indices of USA, UK, Singapore, and Japan have been considered. If countries of the same region have a long run relationship then chances of an optimum currency area increases whereas, a diversification strategy to reduce risk is not workable. Results among the developed and Asian countries show that volatility transmission is present between friendly countries of different regions with economic links. We also find some evidence of transmission of volatility between countries which are on unfriendly terms.     

New empirical evidence on CEE's stock markets integration

The main aim of the study was to explore the integration of CEE’s stock markets (Central, South-East and Baltic) with those of the developed ones (Germany, USA and the UK). Using daily data from 20 October 2000 up to 20 October 2016, the static analysis indicates a long-run cointegration relationship between CEE markets and all three counterparts considered. The dynamic analysis indicates several short-run episodes of cointegration, which are influenced by nondomestic factors. When comparing among the counterparts, one can highlight that the US stock market is less integrated with emerging markets, which could be considered for portfolio diversification. Furthermore, the contagion effect is not rejected, given that the dynamic pairwise correlations are likely to be affected by herding behaviour and significant break dates.     

Testing for stock return predictability in a large Chinese panel

This paper proposes a simple panel data test for stock return predictability that is flexible enough to accommodate three key salient features of the data, namely, predictor persistency and endogeneity, and cross-sectional dependence. Using a large panel of Chinese stock market data comprising more than one million observations, we show that most financial and macroeconomic predictors are in fact able to predict returns. We also show how the extent of the predictability varies across industries and firm sizes.     

Analyst coverage network and stock return comovement in emerging markets

This paper shows that analyst coverage networks (ACN) play an important role in explaining stock return commonalities across Latin American stocks. First, pairs of stocks connected by analysts exhibit higher comovement and excess comovement. Second, firms easily traded by foreign investors are more strongly affected by common coverage. Third, international analysts are an important source of across-country excess comovement. Finally, by creating the network at the brokerage house level and exploiting exogenous changes in ACN around the MSCI LATAM Index reviews, this study addresses endogeneity concerns related to the effect of ACN on commonalities.

An examination of predictable risk and return in UK stock returns

This paper examines whether conditional asset pricing models can explain the predictability in UK stock returns using the frameworks of Ferson and Harvey (1999) and Kirby (1998). The paper finds that the domestic Arbitrage Pricing Theory model is able to explain most of the observed time-series predictability in stock returns and tends to perform better than the domestic CAPM in explaining the predictability generated by the predictive instruments. The paper also finds that domestic asset pricing models tends to capture more of the time-series predictability in UK stock returns than international models. However none of the models are able to explain all of the predictability in returns.

Common risk factors in returns in Asian emerging stock markets

This paper examines the application of the Fama and French's (1993) three-factor model in three Asian emerging markets (Hong Kong, Singapore and Taiwan). The empirical evidence is consistent with the US findings that the model can explain most of the variations in average returns. However, we find that the main contributing factor is the contemporaneous market excess returns. The impact of the size effect and book-to-market (BE/ME) factor is limited and in some cases insignificant. When the three-factor model is modified by using lagged market excess returns instead in order to check for the predictability of the market factor, the explanatory power of the model drops substantially but both the risk factors for size and BE/ME are now able to contribute significantly in explaining the cross-sectional variations of stock returns. Their explanatory powers are strongest for small-size with high BE/ME portfolios. The robustness of our results is also checked for the separation of up and down markets periods and January effect.
