Financial asset prices reflect investor's perspectives over the current and future situation of a firm, an industry, a country and ultimately, the entire economy. For this reason, how financial asset prices are driven has been a fundamental economic question. Specific market characteristics such as the number of sellers and buyers, investors valuation perceptions, market availability of other assets and legal and technical properties are some of the features that affect asset prices. When the same asset is traded at different venues, these specific characteristics may vary, following a certain degree of heterogeneity across buyers and sellers. The direct consequence is that transaction prices of the same asset differ across markets. However, prices will also not drift apart, since arbitrage opportunities would arise, reducing or even eliminating the differences. Prices of similar securities linked to a single latent price, as derivative markets, for instance, present the same behaviour. Price differences among markets observed at high frequencies are an indication that venues incorporate new information in an unlike way. The structure and design of a market impacts its behaviour, liquidity, effciency, and hence how prices are discovered. The task of identifying the leading markets and understanding how the price dynamics occurs are the main objectives of the price discovery analysis. Chapter 1 introduces the research subject of price discovery, motivating the importance of what this thesis proposes and the results and conclusions obtained. Chapter 2 explains in details the main methodologies used to measure price discovery and the important results in the empirical literature. Chapter 3 motivates the data set this thesis uses, with institutional background details and specific market and firm characteristics. We also present in details the steps we follow to deal with standard issues of high frequency data, such as outliers and errors on a tick-by-tick database and non synchronicity of prices at different markets. Chapter 4 extends the standard price discovery model to estimate the information share (IS) accounting for the information content of both common and preferred non US stocks, their American Depositary Receipts (ADRs) counterparts traded on the New York Stock Exchange and ARCA, and the exchange rate. We gauge the significance of price discovery in the home and foreign markets, through common or preferred stocks. One of the main critiques on the IS methodology is that it does not deliver a single measure when there is contemporaneous correlation among markets. We propose an ordering invariant methodology that delivers a single measure of IS.We find that the foreign market is more important than the home market for the price discovery of Petrobras, the Brazilian stated-owned oil giant, and Vale, one of the largest mining companies in the world. Additionally, the Brazilian market has lost significant importance after the 2008/2009 financial crisis. During this period, common and preferred stocks shared a single common factor, with voting premium being a stationary process. Chapter 5 investigates instantaneous and long-run linkages between common and preferred shares traded at both domestic and foreign markets. We develop a market microstructure model in which the dynamics of the different share prices react to three common factors, namely, the efficient price, the efficient exchange rate, and the efficient voting premium. We show how to identify the structural innovations so as to differentiate instantaneous and long-run effects. First, we obtain dynamic measures of price discovery that quantify how prices traded at different venues respond to shocks on the common factors. Second, we are able to test whether shocks in the efficient exchange rate change the value of the firm. Third, we test whether shocks on the efficient voting premium have a permanent effect on preferred shares. We implement an empirical application using high-frequency data on six Brazilian large companies. We find that, in the long-run, a depreciation of the Brazilian currency leads to a depreciation of the value of the firm that exceeds the expected arbitrage adjustment. In addition, a positive shock on the voting premium yields a positive impact on the value of the firm. Our price discovery analysis also reveals that one trading day suffices to impound new information on all share prices, regardless of the venue they trade at. Finally, Chapter 6 concludes.

Abstract This thesis analyses the stock market synchronicity of 34 emerging markets and compares the findings with seven developed markets. The study uses weekly stock return data and the final dataset includes approximately 20.8 million weekly observations for 40,014 firms across the world. Morck et al. (2000) are among the first to introduce the topic of stock market synchronisation and argue that stock markets in economies with high per capita GDP move in a relatively unsynchronised manner over time, in contrast to stock prices in low per capita GDP economies. They also suggest that stock synchronicity is associated with macroeconomic indicators including rule of law, inflation, corruption and geographical size. In addition, Skaife et al. (2006) propose a further measure of stock synchronicity based on the proportion of zero returns and argue that the zero-return measure is a superior measure of stock market co-movement. The study uses both measures proposed by Morck et al. (2000) and one measure proposed by Skaife et al. (2006) for synchronicity analysis and extends the analysis to cover a ten year period, a larger sample of shares and more recent measures of country specific characteristics. It is found that stock markets in emerging economies are more synchronous than in developed economies over the sample period using the classical measure. It is also found that over the 10-year study period the synchronicity measure is stationary. There is evidence of a statistically significant negative correlation between stock synchronicity and both government accountability and corruption for the emerging markets using the cross-sectional analysis. The R-square measure of stock synchronicity averages 0.091 for the emerging markets and 0.045 for the developed economies, suggesting that higher stock price co-movement is evident in emerging economies. Further, there is a statistically significant positive correlation between the R-square measure and both corruption and inflation. The study also uses the zero-return measure of stock synchronicity suggested by Skaife et al. (2006). It is found that the zero-return measure for emerging economies is higher than for developed economies. Surprisingly, China and the S&P 500 group of companies exhibit the lowest values for the zero-return measure during this period, which is inconsistent with the classical measure and the R-square measure. Further, panel data analysis shows that GDP per capita and trade openness have a strong effect on the zero-return measure. The Pearson correlation and Spearman rank correlation coefficient indicate that the classical measure and the R-square measure are positively correlated and appear to capture similar aspects of the markets in the study, which is also consistent with cross-sectional analysis results. In contrast, the zero-return measure shows either insignificant or negative correlation with the classical measure and the R-square measure for most sub-period and full period analysis. Finally, there is evidence that emerging stock markets are more synchronous over time than in developed financial markets. It is found that common-law country stock synchronicity is lower than in civil-law countries or post-communist countries using the classical measure and the R-square measure.

Drawing on recent discussions of relational embeddedness and socio-technical agencement, this thesis analyses the relationship between stock trading and lay investors’ daily lives, including their social relations, activities, events, devices, places, work and ways of thinking. Taiwan’s stock market provides an appropriate location for investigation because of the dominance of lay investors in the market and the high proportion of Taiwan’s adult population who engage in stock trading. The data were obtained from three main sets of sources: in-depth interviews, document analysis and ethnographic observation. I argue that lay market actors are not only framed by the market’s mechanisms, but also by daily-life structures. The Taiwan Stock Exchange, as an electronic, anonymous financial market, has been a challenge to the embeddedness approach due to the absence of direct interaction between the parties to transactions. This study presents another aspect of socio-economic relationships in the market: the role of financial-market activity in wider social interactions. Like taking part in any popular social activity, lay investors’ social ties are maintained and expended by engaging in stock trading. Social relations and stock trading are woven together and form a largely seamless whole, part of lay investors’ daily life. The socio-technical agencements of lay investors contain distinctive features: diversity, bricolage, use of non-professional ‘devices’, action in non-financial places, everyday means of controlling market risk and association with everyday events. The differences between the agencements of lay investors and professional practitioners produce an asymmetry of calculative capabilities between market actors. Superior calculative capabilities tend to give an advantage to professional practitioners in the market, but these strengths are constrained by political and economic factors. This study sheds light on micro social factors, which are comparable with economic, institutional and psychological explanations, in accounting for lay investors’ behaviours in financial markets. The analysis also suggests the compatibility of the three important social science approaches to economic agents: Granovetter’s embeddedness, Zelizer’s relational work and Callon’s agencement.

A dissertation submitted to the Wits Business School, Faculty of Commerce, Law and Management, in partial fulfillment of the requirements of the candidacy of the Masters of Management in Finance and Investments University of Witwatersrand April 2016 / The aim of this paper is to investigate financial contagion in African financial markets from the global financial crisis. Interest in this subject has grown exponentially in the recent past in light of expanding globalization. The empirical analysis is based on daily stock price indices of a sample of African countries in order to compute the stock returns and find the impact of correlations between them and the US market. The empirical evidence is based on correlation tests by Forbes& Rigobon (2002). The analysis suggests that the larger markets by market capitalization and number of traded stocks exhibit co-movement, whereas the smaller markets experience financial contagion. The results have implications for financial investment process and risk management in terms of globalization and the unfolding of financial liberalization in Africa. / GR2018

Thesis submitted in fulfilment of the requirements for the degree of Master of Management in Finance and Investment (MMFI) in the Faculty of Commerce, Law and Management Wits Business school at the University of Witwatersrand, 2016 / This thesis studied the effects of terrorist attacks on Kenya‟s financial markets between January 2004 and December 2014. The study uses an augmented asset-pricing model similar to that in Eldor and Menelik (2004). The model includes terrorist attack dummies representing location of the attack, the type of attack, the intended target, number of people injured and number of people killed. Data on the terrorist attacks and share index values and foreign exchange rates variables are used to estimate the model. The results show that attacks carried out using explosives had a positive impact on share prices on the NSE. On the flipside, attacks that were carried out on facilities/infrastructure or on religious figures/institutions as well as those carried out using incendiaries had a negative impact on the NSE. An increase in the number of people injured also led to a greater negative impact on the NSE. As regards the forex market, attacks carried out using firearms and incendiaries led to a depreciation of the local currency. Transport attacks on the other hand led to an appreciation. Similarly, the greater the number of people injured led to a greater appreciation of the KES / GR2018

A Doctoral thesis submitted in fulfilment of the requirements for the award of Doctor of Philosophy degree in the field of Finance The Graduate school of Business Administration, University of the Witwatersrand, October 2016 / The global financial system has experienced turmoil in the past three decades, at the least. Although the shocks originate abroad, they possess some rippling effects on African economies. The essence of market integration and cross-border listings of stocks has fueled the need for African markets to be well integrated with the global economy. Despite this need, available empirical literature exploring the integration of African markets regionally, and with the rest of the world appear unclear. Moreover, the possibility of global shocks transmitting to Africa via its emerging equity markets remains underexplored. At the same time, such knowledge is critical for not only understanding the functioning of equity markets in particular, but also important for regulating the financial system in general. This thesis addresses these gaps inherent in extant literature and proffer empirical and theoretical solutions by exploring the nexus between African stock markets and global shocks. The emphasis is on contagion, co-movement, and diversification. The thesis is organized into four empirical essays, each deeply touching on specific theme (s) that form the core of the problems or research questions under investigation while employing advanced econometric techniques that underpin the modeling of asset returns. The first essay examines the capacity of African equity markets to act as ‗hubs‘ for portfolio investors during tranquil and turbulent conditions of global equity and commodity markets. The findings posit that African stock markets provide decorrelation from commodity and global equity markets during extreme market conditions. To the extent that the results reveal the strength of African stocks in cushioning international portfolio investors in a mean-variance stand-point during market crashes, the essay helps to decay doubts in the minds of investors on the perceived lack of capacity of the continent‘s stocks to yield higher expected risk-return trade-offs during global market sell-offs. The implication of the study is that given the recent history of commodities and global stocks, fund managers around the world seeking viable alternatives to compensate for losses from commodity shocks through uncorrelated markets may consider the equity markets in Africa, albeit on account of volatility persistence, present and past market conditions, markets stability, as well as size and liquidity issues. The second essay examines regional and global co-movement of African stock markets using the three-dimensional continuous Morlet wavelet transform methodology. The essay establishes evidence of stronger co-movements broadly narrowed to short-run fluctuations. The co-movements are time-varying and commonly non-homogeneous – with phase difference arrow vectors implying lead-lag African Equity Markets and Global Shocks 2016 © Gideon Boako Page iii relationships. The presence of lead-lag effects and stronger co-movements at short-run fluctuations may induce arbitrage and diversification opportunities to both local and international investors with long-term investment horizons. The findings also reveal that some African equity markets are, to a degree, segmented from volatilities of the dollar and euro exchange rates. The third essay sheds light on whether African equity markets decoupled from, and / or converged with regional and global markets from 2003 to 2014, and analyzes the implications of that for shocks spillovers. Although there is no evidence of African markets convergence either regionally or globally, shock propagation exists in a time-varying setting. Regional markets in Africa are not just ‗shock absorbers‘ but also ‗shock transmitters‘. In the last essay, the dependence structure and (extreme) downside developed equity markets and currency price risk spillover effects to African stock markets using value-at-risk (VaR) and conditional value-at-risk (CoVaR) based on stochastic copulas is modeled. The study finds evidence of non-homogenous weak negative dependence between stocks and the USD and EUR exchange rates. Except for Egypt, there is evidence of positive significant dependencies between all African markets and their developed counterparts. Although, evidence of both uni-directional and bidirectional causality, as well as upper and lower tail dependencies are found across the stocks and currency markets, only some minuscule evidence of downside spillover effects was recorded, albeit episodic. It is observed that propagation of shocks from the GFC had a second round effect in African stock markets. Thus, the impact of the GFC to African economies was not through the credit crunches and liquidity freezes in Phase I of the crisis, but rather through the global recession that followed into the second phase. The findings are consistent with the view that global shocks propagation to developing markets may stagger during crisis and intensify post-crisis. A practical implication from the results is that given the relatively scarce resources and levels of technological know-how available to African governments, efforts to wean the continent‟s equity markets from adverse effects of global market crashes should be geared towards plans and programmes to mitigate the shocks not at the early stages but latter stages, where the effects to Africa could be prominently felt. Three key arguments are deduced from all the essays. First, although financial market underdevelopment seems prima-facie, to help countries isolate themselves against immediate contagion, it also reduces the ability of the real economy to cushion the impact of the crisis. African Equity Markets and Global Shocks 2016 © Gideon Boako Page iv Therefore, the argument of the thesis is that despite the common fear that a highly integrated and developed market may present fertile grounds for shock spillover, Africa must continue to pursue programmes aimed at enhancing inter and intra-regional integration. However, the degree and extent of both inter- and intra-regional integration ought to be pegged at certain optimal levels in order to reap benefits from scale economies. Such endeavours at integration will not only help in risk diversification but also help smooth the impact of shocks. The second argument is that, the proposition of the ―decoupling theory‖ i.e. returns of African equity markets and global stocks are not jointly normal during crisis periods may not be entirely tenable, empirically. Thirdly, the thesis argues that the “shift-contagion” theory may not reflect the reality for Africa, particularly during initial stages of crisis. Instead, the thesis suggests an extension and argues for a “delayed-shift contagion” theory. Keywords: Decoupling, shift-contagion, spillover effects, CoVaR, exchange rates, commodities.
