Volatility Co-Movement in Saudi Arabian and Kuwaiti Stock Markets


Book Description

We use data on realized volatility to establish co-movement in volatility on the Saudi Arabian and Kuwaiti stock exchanges. We show, in addition, that the probability of positive and negative co-movement are related to the volatility of international equity prices and volatility of oil prices.




Oil Price Movements and Equity Returns Evidence from the GCC Countries


Book Description

This study examines to what extent how oil movements differently affect equity returns in general and sectoral levels of the GCC countries stock markets. Modeling the equity returns volatility requires using GARCH-type models. These models help to explore the pronounced differences of the conditional variance structures across sectors and markets. Chapter 1 compares the effects of changes in oil price return and its volatility on equity returns and volatility across sectors. The findings of this chapter show that despite the GCC states dependency on oil revenues, equity market performance at the sectoral level do not exactly associate with oil movements. Our results, in particular, show that the GCC stock markets do not always move hand-in-hand with oil market movements. In chapter 2, we explore the relationship within a specific sector, i.e. Banks sector in Saudi Arabia Stock market. We examine if oil price changes affect Islamic banks differently than conventional ones. The findings show a decrease in degree of co-movement between these two types of banking system and oil market, meaning that they are less integrated. Although the Islamic banks kept a higher degree of co-movement with oil, limitations of Shari'ah restrictions on Islamic banks have little impact on the relationship between oil and those banks. Chapter 3 examines whether the level of corruption influences how oil changes affect the GCC stock markets. The findings of chapter 3 show that dissimilar levels of corruption between GCC countries have inconsiderable differences on the oil return effects on the GCC stock markets. Oil returns affect both low and high level of corruption groups. The oil return innovation affects the equity volatility for Saudi Arabia and Kuwait more than other four GCC countries.




The Impact of Trading Volume on Stock Price Volatility in the Arab Economy


Book Description

This study intends to examine the price-volume movements in the Arab stock markets, in order to determine the impact of changes in trade volume on the volatility of stock prices as expressed by the unified MAF stock price index. The research covers a sample of eight out of the fifteen Arab stock markets included in the Arab Monetary Fund database, using monthly data from 1994 to 2006. The study found that there is an increasing in both trading volume and stock price volatility, which may be considered as a recent phenomenon in the majority of the Arab stock markets. The study also found that the volume-stock price movements are significantly integrated for all selected markets, while the highest correlation coefficient between volume and stock price movement was found in Saudi stock market, Amman stock market, Muscat stock market and Kuwait stock market respectively. Finally, the correlation between volume and prices movement is higher in the stock markets of the oil Arab states compared to the non-oil Arab states.

Global and Regional Spillovers to GCC Equity Markets


Book Description

This paper analyzes the impact of global and regional spillovers to GCC equity markets. GCC equity markets were impacted by spillovers from U.S. equity markets despite varying degrees of foreign participation. Spillovers from regional equity markets were also important but the magnitude of the effects were on average smaller than that from mature markets. The results also illustrated episodes of contagion in particular during the recent global financial crisis. The findings suggest that given the degree of openness, and open capital accounts the financial channel is an important source through which volatility is transmitted. In this regard, GCC equity markets are not immune from global and regional financial shocks. These findings refute the notion of decoupling between the GCC equity and global equity markets.




Intelligent Optimization Modelling in Energy Forecasting


Book Description

Accurate energy forecasting is important to facilitate the decision-making process in order to achieve higher efficiency and reliability in power system operation and security, economic energy use, contingency scheduling, the planning and maintenance of energy supply systems, and so on. In recent decades, many energy forecasting models have been continuously proposed to improve forecasting accuracy, including traditional statistical models (e.g., ARIMA, SARIMA, ARMAX, multi-variate regression, exponential smoothing models, Kalman filtering, Bayesian estimation models, etc.) and artificial intelligence models (e.g., artificial neural networks (ANNs), knowledge-based expert systems, evolutionary computation models, support vector regression, etc.). Recently, due to the great development of optimization modeling methods (e.g., quadratic programming method, differential empirical mode method, evolutionary algorithms, meta-heuristic algorithms, etc.) and intelligent computing mechanisms (e.g., quantum computing, chaotic mapping, cloud mapping, seasonal mechanism, etc.), many novel hybrid models or models combined with the above-mentioned intelligent-optimization-based models have also been proposed to achieve satisfactory forecasting accuracy levels. It is important to explore the tendency and development of intelligent-optimization-based modeling methodologies and to enrich their practical performances, particularly for marine renewable energy forecasting.




Geopolitical Risk on Stock Returns: Evidence from Inter-Korea Geopolitics


Book Description

We investigate how corporate stock returns respond to geopolitical risk in the case of South Korea, which has experienced large and unpredictable geopolitical swings that originate from North Korea. To do so, a monthly index of geopolitical risk from North Korea (the GPRNK index) is constructed using automated keyword searches in South Korean media. The GPRNK index, designed to capture both upside and downside risk, corroborates that geopolitical risk sharply increases with the occurrence of nuclear tests, missile launches, or military confrontations, and decreases significantly around the times of summit meetings or multilateral talks. Using firm-level data, we find that heightened geopolitical risk reduces stock returns, and that the reductions in stock returns are greater especially for large firms, firms with a higher share of domestic investors, and for firms with a higher ratio of fixed assets to total assets. These results suggest that international portfolio diversification and investment irreversibility are important channels through which geopolitical risk affects stock returns.




Global Stock Market Integration


Book Description

Stock market integration between developing and emerging markets has numerous benefits for creating a global - yet stable - world economy. It increases competition and the efficiency of local markets, in turn reducing price volatility and the cost of capital among integrated markets. It also generates capital flows, which enhance financial stability and spur economic growth. At its core, stock market integration has an important role to play in both developing and emerging markets still reeling from the global financial crisis. Global Stock Market Integration analyzes the financial makeup of developing and emerging markets around the world, providing empirical insights into market integration, co-movements in price, crises, and efficiency linkages. Mobarek and Mollah argue that the relationship between market integration and market efficiency within developing and emerging countries is not the only measure necessary for effecting real financial growth. This work brings the review of theories and empirical research on the topic up-to-date and expands the existing literature with new perspectives on developed and emerging markets.




Routledge Handbook of Energy Economics


Book Description

Energy consumption and production have major influences on the economy, environment, and society, but in return they are also influenced by how the economy is structured, how the social institutions work, and how the society deals with environmental degradation. The need for integrated assessment of the relationship between energy, economy, environment, and society is clear, and this handbook offers an in-depth review of all four pillars of the energy-economy-environment-society nexus. Bringing together contributions from all over the world, this handbook includes sections devoted to each of the four pillars. Moreover, as the financialization of commodity markets has made risk analysis more complicated and intriguing, the sections also cover energy commodity markets and their links to other financial and non-financial markets. In addition, econometric modeling and the forecasting of energy needs, as well as energy prices and volatilities, are also explored. Each part emphasizes the multidisciplinary nature of the energy economics field and from this perspective, chapters offer a review of models and methods used in the literature. The Routledge Handbook of Energy Economics will be of great interest to all those studying and researching in the area of energy economics. It offers guideline suggestions for policy makers as well as for future research.
