What are the benefits of globally invested mutual funds? Evidence from statistical arbitrage models

Even though correlations between different economies’ stock markets have empirically increased over time, it would have been advantageously to invest in developing countries' stock markets such as the Indian stock market, instead of investing in the US-stock market when considering the overall market returns of the last decade. Anticipating beneficial asset allocations is challenging since higher returns are basically associated with higher risks. The estimation procedure which is employed in this study to construct globally invested portfolios is based on cointegration analysis. The forecast period covers 11 years.

Volatility impact of stock index futures trading - A revised analysis

The recent financial crisis renewed concerns about a possible destabilizing impact of derivatives trading. Despite a very active research, the question whether or not derivatives tend to destabilize financial markets has not yet been answered to satisfaction. This contribution aims to revise the robustness of recent empirical findings and to remedy some methodological shortcomings of earlier studies. Acknowledging their practical relevance, we focus on futures and examine the volatility impact of DAX futures trading. Our results confirm a volatility-reducing impact of DAX futures trading, whereas the observed deterioration of the fundamental price building process proved to be statistically insignificant.

Most admired companies: Admirable performance

This paper shows that most admired companies generate admirable stock performance relative to the market. The current study analyses risk premiums and risk-adjusted excess returns of a portfolio of firms ranked as the most admired companies in the United States from 2006 to 2011. The results show that average risk premiums of an equal-weighted portfolio of most admired firms are economically superior than the market risk premiums from 2006 to 2011 (except 2010). For the 1-year holding period, the portfolio average risk-adjusted excess returns are all positive, but 2010, and some even statistically significant. The portfolio exhibits average positive risk-adjusted excess returns for the 3-year holding period intervals; the alphas are statistically significant for the 2006-2008 period.

Market timing and statistical arbitrage: Which market timing opportunities arise from equity price busts coinciding with recessions

Even though a random walk process is from a statistical point of view not predictable, some movements can be correlated with specific events concerning other variables. Then, predictable patterns may arise being dependent on this joint event. There is evidence given that equity price busts being associated with recessions continue until the economy switches from the state of recession to an economic pick-up.

Independent directors and the long-run performance of IPOs

The Securities and Futures Bureau (SFB) of Taiwan prescribes that firms applying for an initial listing after February 2002 must have at least two seats of independent directors (IDs) on the board. Under the SFB 2002 rules, this paper investigates the effect of such governance reforms in ID requirement on the long-run performance of IPOs. Our results, based on 494 IPOs between 1999 and 2005, find that though IPOs typically underperform in the post-issue period, firms after 2002 perform better than those before 2002. Moreover, firms with IDs also experience less negative stock performance than those without IDs. The results further suggest a positive association between the proportion of IDs on corporate boards and post-listing stock performance for IPOs after 2002.

Does the investor sentiment affect the stock returns in Taiwan’s stock market under different market states

Climatic change and epidemic disease could influence the investor sentiment. Under such circumstances, how to invest the stock market in different stock market states (bull, bear or neutral) is an important topic for investors. To capture the investor sentiment more precisely, we use principal component analysis to analyze some investor sentiment indicators, and then form a composite index of investor sentiment. These investor sentiment indicators include the turnover rate, the percent change in margin borrowing, the percent change in short interest, net buy/sell, the turnover ratio of major institutional investors, psychological line, and advance decline ratio.

Does subprime crisis affect Chinese stock market returns

This paper aims at testing the influence of Subprime Crisis on Chinese stock market returns. By means of newly proposed time series spatial analysis methodology, we investigate the dominance behavior of daily returns on both Shanghai Stock Exchange Composite Index and Shenzhen Stock Exchange Component Index between before and after the crisis. Little spatial dominance could be found, even considering the appreciation of the RMB, no matter in short-term or long run investment. For rationale investors, there are no significant risk and preference changes about domestic stock market in the post Subprime Crisis era.

The forecasting performances of volatility models in emerging stock markets: Is a generalization really possible?

In almost all stages of forecasting volatility, certain subjective decisions need to be made. Despite of an enormous literature in the area, these subjectivities are hindrances to reaching an overall conclusion on the performances of the models. In order to find out outperforming model in general not just in the contexts of studies, volatility models should be evaluated in many markets with the same methodology consisting both simple and complex models at different forecast horizon.

Testing the profitablitiy of a volume-augmented momentum strategy in the Philippines equity market

This study contributes new empirical evidence on the profitability of a momentum strategy in the Philippines equity market. The study was conducted over the time period January 2000 to June 2012. We evaluated a momentum strategy based only on past return information as well as a strategy that incorporates information on volume for 16 different time combinations with varying formation and holding periods. For the strategy based only on past return information, we find little evidence in support of the profitability of a momentum strategy with the results suggesting the presence of mean-reverting prices.

Regional and international causal linkages. evidence from CEE stock markets

This study examines the dynamic linkages between nine Central and Eastern European (CEE) emerging markets and the developed ones, i.e. Austrian, French, German, British and American stock markets. To investigate the nature of transmission of information we employ two econometric models which are estimated in framework of maximum likelihood, GARCH, and vector autoregression. Our findings suggest that there exist some reaction from CEE markets to the arrival of price innovations from the developed markets, but the nature of these reactions and responses is mixed.

Price leadership between spot and futures markets

This paper aims to study the relative information shares of spot and futures market at the individual stock level to measure the price discovery in spot and futures market in the Indian capital markets. We find that the spot and futures prices are co-integrated and mutually adjusting. Building on Information Share approach of Hasbrouck, the price discovery share of futures segment is about 36% compared to that of spot segment is 64%. It is expected that futures market contribute more towards price discovery given huge trading volumes and they carry the natural advantage of cost-effectiveness in terms of leverage benefit.

Stock returns with price impact

In this paper, we study the stock returns for large trades with price impact. We use the daily changes in volume-weighted average price (VWAP) as a proxy of the returns for institutional investors. This return is then compared statistically to the daily return using closing price. Using a panel data of NYSE/AMEX stocks, we find a fixed effect contributing to the spread between them and it can be interpreted as an unbiased ex post estimate of price impact.
