We apply GARCH (p, q) and ARCH(m) model to the daily return of DSE general index (DGEN) ranging from 1<sup>st</sup> January, 2002 to 30<sup>th</sup> July 2013 for examining market volatility. Besides, we calculate year wise standard deviation of daily return of DGEN for the same period. The result of GARCH (1, 1) process and standard deviation of the daily return confirms an abnormal volatility episode from 2009 to 2012. The highest per day volatility was observed in the first half of 2011 in both investigations. The volatility rate found in GARCH (1, 1) process is 2.44% in 2011 followed by 2.00% and 1.99% in 2009 and 2012 respectively. The highest standard deviation of return is 2.99% in 2011 followed by 2.08% in 2012 authenticate the highest volatile periods of the study. We apply ARCH (m) model in 2004 and 2013 for volatility estimate due to inapplicability of GARCH (p, q) process in those market return. The results of ARCH (m) model confirm reliable estimates of market volatility, 1.10% and 1.46% respectively. This is a part of our total research work where our main focus is to detect the factors affecting market volatility and its spillover effects in emerging markets.

This study employs OLS, GARCH and EGARCH regression models to test the expiration-day effects of index stock futures on market returns, volatility and trading volume for the Ho Chi Minh Stock Exchange (HOSE). Data used in this study is from a daily return series of the VN30-Index for the period from 10August 2017 through 30 June 2020. The results derived from GARCH(1,1) and EGARCH(1,1) models consistently confirm that Index futures expiration-day effects on market returns exists in the HOSE. Specifically, the average market return for expiration days is significantly lower than other trading days, by 0.13% at the 5% level of significance. However, the results obtained from the regression models indicate that the expiration-day has no impact on market volatility and trading volume.

Purpose The purpose of this paper is to determine the performance implications of cross-border acquisitions by Polish multinationals. Additionally, the study considers specific factors affecting acquisition performance, such as acquirer’s prior cross-border acquisition experience and the type of market (advanced versus emerging) in which the target is located. Design/methodology/approach This study is based on a sample of 104 cross-border acquisition events in which a Polish public company, quoted on the Warsaw Stock Exchange acted as an acquiring party. The event study method was applied to determine the impact of acquisition announcements on the share price of the acquiring companies for 3-, 4- and 5-day event windows. The proposed hypotheses were additionally verified through hierarchical regression. Findings The research shows that a typical cross-border acquisition carried out by a Polish multinational ends in creating value. While the impact of prior cross-border acquisition experience is only significant for the shortest event window, the choice of targets from emerging markets significantly improves acquisition outcomes for all of the event windows examined. Originality/value The study is the first project on such a scale to focus on cross-border acquisitions by multinationals from Central and Eastern Europe to have used event study methodology. It has shown that acquirers from mid-range emerging markets, such as Poland, tend to benefit more from leveraging their ability to function in underdeveloped and dynamic institutional settings if they acquire companies operating in other emerging markets rather than those based in more developed economies.

This study investigates the influence of herd behavior on the Pakistan stock exchange indexes KSE-100 and KSE-30 during bullish and bearish markets. Using the daily market return from 2007 to 2020. We implement the method of main herding measures, Cross-sectional absolute deviation, and Cross-sectional standard deviation, to explore the influence of herd behavior in the emerging market of Pakistan. The results indicate the presence of market-wide herd behavior: (a) along with the different direction of market positive and negative return, (b) when trading volume high, (c) when stock market highly volatile, and (d) during and the post-financial crisis. Moreover, Investors don’t herd when low trading volume and low volatility. Our study fills the gap in the literature and contributes to academic relevance by exploring the influence of herd behavior among both bull and bear periods in markets of Pakistan, it also examines the possible asymmetric effects of herding related to the market with high-low trading volume and market volatility.

The major objective of the study is to examine the performance of optimal hedge ratio and hedging effectiveness in stock futures market in National Stock Exchange, India by estimating the following econometric models like Ordinary Least Square (OLS), Vector Error Correction Model (VECM) and time varying Multivariate Generalized Autoregressive Conditional Heteroscedasticity (MGARCH) model by evaluating in sample observation and out of sample observations for the period spanning from 1st January 2011 till 31st March 2018 by accommodating sixteen stock futures retrieved through www.nseindia.com by considering banking sector of Indian economy. The findings of the study indicate both the in sample and out of sample hedging performances suggest the various strategies obtained through the time varying optimal hedge ratio, which minimizes the conditional variance performs better than the employed alterative models for most of the underlying stock futures contracts in select banking sectors in India. Moreover, the study also envisage about the model selection criteria is most important for appropriate hedge ratio through risk averse investors. Finally, the research work is also in line with the previous attempts Myers (1991), Baillie and Myers (1991) and Park and Switzer (1995a, 1995b) made in the US markets

Sukuk and Bonds has differences and similarities. Fundamental differences between sukuk and bonds are first, underlying asset in every sukuk issuance, concept of profit loss sharing and the use of Islamic contracts. Whereas conducted research in practice of differences between sukuk and bonds are still an on-going discussion. This study aims to add the evidence in the discussion regarding whether there is differences between sukuk and bonds in the world of practice, provide investment preferences as well as educating investors in choosing sukuk or bonds as a sustainable and smooth instrument. The method used is Mann Whitney U-Test to test whether there is a different between yield to maturity (return) and standard deviation (risk) of both instruments. Using secondary data of Retail Sukuk (SR) and Retail Bonds (ORI) period 2008-2017 obtained from Indonesia Stock Exchange, Indonesia Bond Market Directory and Indonesia Bond Pricing Agency. The result shows that there is no significance difference of retail sukuk return and risk with retail bonds in Indonesia. Besides retail bonds are show higher return than retail sukuk because of higher coupon and longest mature date. While, retail sukuk is more stable rather than bonds as it backed up by the real underlying asset. Keywords: Retail Sukuk (SR), Retail Bonds (ORI), Yield to Maturity


Barely two decades after the Asian financial crisis Asia was suddenly confronted with multiple challenges originating outside the region: the 2008 global financial crisis, the European debt crisis, and, finally developed economies’ implementation of unconventional monetary policies. Especially the implementation of quantitative easing (QE), ultra-low interest rate policies, and negative interest rate policies by a number of large central banks has given rise to concerns over financial stability and international capital flows. One of the regions most profoundly affected by the crisis was Asia due to its high dependence on international trade and international financial linkages. The objective of this book is to explain how macroeconomic shocks stemming from the global financial crisis and recent unconventional monetary policies in developed economies have affected macroeconomic and financial stability in emerging markets, with a particular focus on Asia. In particular, the book covers the following thematic areas: (i) the spillover effects of macroeconomic shocks on financial markets and flows in emerging economies; (ii) the impact of recent macroeconomic shocks on real economies in emerging markets; and (iii) key challenges for the monetary, exchange rate, trade, and macroprudential policies of developing economies, especially Asian economies, and suggestions and recommendations to increase resiliency against external shocks.

The volatility analysis of stock returns data is paramount in financial studies. We investigate the dynamics of volatility and randomness of the Pakistan Stock Exchange (PSX-100) and obtain insights into the behavior of investors during and before the coronavirus disease (COVID-19 pandemic). The paper aims to present the volatility estimations and quantification of the randomness of PSX-100. The methodology includes two approaches: (i) the implementation of EGARCH, GJR-GARCH, and TGARCH models to estimate the volatilities; and (ii) analysis of randomness in volatilities series, return series, and PSX-100 closing prices for pre-pandemic and pandemic period by using Shannon’s, Tsallis, approximate and sample entropies. Volatility modeling suggests the existence of the leverage effect in both the underlying periods of study. The results obtained using GARCH modeling reveal that the stock market volatility has increased during the pandemic period. However, information-theoretic results based on Shannon and Tsallis entropies do not suggest notable variation in the estimated volatilities series and closing prices. We have examined regularity and randomness based on the approximate entropy and sample entropy. We have noticed both entropies are extremely sensitive to choices of the parameters.
