We study some aspects of liquidity of stocks traded through the National Stock Exchange (NSE) of India. Initially we examine the multi-dimensional nature of liquidity by conducting day-wise factor analysis of eleven liquidity proxies across a cross-section of stocks, using data from two periods reflecting different market conditions. Five factors emerge consistently, interpretable as depth, spread, volume, price elasticity and relative activity. Subsequently, we study execution of limit orders in the NSE from three angles. First we consider order execution probability, using 106 stock-specific logistic models. Important predictors of order execution probability are price premium followed by volatility, relative activity, bid ask spread and order imbalance. Some differences are noted when comparing companies of different sizes and between buy and sell orders. Second, we study order execution times using survival analysis. Several diagnostic tests indicate that parametric Accelerated Failure Time models using the log-logistic distribution for the survival time S(t) are suitable for current data. 100 stock-specific models are built; results are consistent with the logistic models. Additionally depth is also found to be important. Finally we build 4 combined models across stocks for both execution probabilities as well as times. These models perform well on out of sample data, suggesting their predictive utility.

The goal of this Masters Thesis is to analyse economic value added generated by non-financial companies listed on Prague stock exchange. Main goal is not only to calculate the amount of economic value added, but also to compare results of two economic models used to specify Re (Minimal required return of companys own capital), necessary to calculate economic value added. Next goal is to analyze link between economic value added and stock price. Correlation between this two parameters would be a sign of possibility to predict future stock price in dependance on generated economic value added. For this Masters thesis, It is important to have all balance sheets, P/L statements and stock market data for all selected corporations. All these informations were exported from database Thomson Reuters Eikon available on University of economics in Prague.

This diploma thesis deals with analysis of the stock price behavior around ex-dividend day, focusing on the European capital market. The theoretic part is aimed at summarizing of hypotheses and effects affecting the amount of the stock price in comparison with an amount of dividend during last 50 years. In the practical part, there is firstly described a methodology of testing, later the 3 main hypotheses are determined, that are finally tested on a sample of 220 European companies listed on twelve stock exchanges, including the Prague stock exchange. The aim will be to determine the validity of hypotheses on the sample as a whole as well as on some selected stock exchanges in the period between 2006 and 2010, the influence of the payment of dividend on share price, but also the potential impact of financial crisis. Furthermore, the possibility of arbitrage opportunities will be evaluated, which could be incurred on some stock exchanges or individual shares, as well as stability, efficiency and predictability of individual capital markets.

Liquidity is a measure of the ease with which an asset can be converted into cash. In a perfectly liquid market, conversion is instantaneous and does not incur costs. Amihud and Mendelson (1986:224) proposed that illiquidity increases the expected return on an investment (liquidity premium) and simultaneously lengthens the holding period. These two effects are known respectively as the “spread-return relationship” and the “clientele effect” and have theoretical as well as practical implications. From a theoretical perspective it may help to explain the gap between the capital asset pricing model (which assumes that markets are perfectly liquid) and the associated empirical evidence; which thus far has been rather poor. From a practical perspective, liquidity will influence stakeholders’ decisions and market competitiveness (Amihud&Mendelson, 1991:61-64). The relevant stakeholders are governments, stock exchange regulators, corporations, investors and financial intermediaries. Emerging economies such as the South African economy typically have less liquid markets than the developed world. While this may be attractive for investors looking for higher returns, Amihud and Mendelson (1991:61) are of the opinion that liquid markets are more generally favoured by investors. Constantinides (1986:842-858), also proposes a model for liquidity, but found the liquidity premium to be of lesser importance than that proposed by Amihud and Mendelson (1986:223-231) but also supports the suggestion that investors will favour liquid markets. Although it is by no means a perfect proxy, a security’s bid-ask spread has been found to be an attractive and effective measure of liquidity. It has been found to correlate with beta as well as market capitalisation and several other variables commonly used in capital markets research. Because of this correlation the effect of the bid-ask spread cannot be studied in isolation when regression techniques are employed (Ramanathan, 1998:166). This is particularly problematic because empirical evidence for beta, which is arguably the most important independent variable in financial cross sectional relationships, is weak. Beta has to be estimated and so it is not clear if real markets do not support CAPM theory or if beta cannot be estimated with the required accuracy. All of the common independent variables used in empirical capital markets research are correlated to beta, and for this reason it cannot be established if these variables have a real effect or if they are simply serving as a proxy for the difference between the real and the estimated beta. Various strategies have been proposed to increase the accuracy of beta estimation and these are discussed in detail in this research. Successes with these strategies have been mixed. A second problem encountered in the empirical research base relating to the CAPM is that in the theory the cross-sectional relationship is between expected market return (which cannot be observed due to the vast number of real investments beyond those listed on exchanges) and beta, whereas empirical research makes use of actual return on a market proxy and beta. In order for the actual return to approach the expected return, empirical studies have to be conducted over extended periods. Accurate data for such periods are generally lacking and severe macro-economic changes such as wars, may also affect rational economic behaviour. It has to be kept in mind that the entire CAPM theory flows from the simple assumption that investors aim to achieve the highest return per unit of risk, and so a rejection of beta is a rejection of rational investor behaviour. Liquidity however, addresses one of the assumptions of CAPM, namely that markets are perfectly liquid; which obviously is not met in real markets and so CAPM models expanded for liquidity should be a reasonably fundamental starting point for all empirical capital markets research. The current empirical evidence for the spread-return relationship is inconclusive. While some researchers have found a significant relationship, others have questioned the ability of the methodology to differentiate a true relationship from the ‘proxy for errors in the estimated beta’ problem. Deductions (as explained in section 4.3) that have been made from the research of Marshall and Young (2003:176-186) in particular, provide strong evidence that at least some of the relationship is due to the ‘errors in estimated beta’ problem. Little empirical work has been done on the clientele effect. Atkins and Dyl (1997:318-321) found a significant relationship between holding period and bid-ask spread, although their approach was somewhat unorthodox in the sense that portfolio formation was not done and the effect of beta was not tested. This study tests empirically both the spread-return relationship and the clientele effect on the Johannesburg Stock Exchange over the period stretching from January 2002 to June 2007. The methodology of Fama and Macbeth (1973:614-617) as well as the aggregated beta of Dimson (1979:203-204) were mainly used, with some modifications as suggested by other researchers. With regard to the spread-return relationship, the findings of this study do not support theoretical expectations. This may be due to the short time period that was used as well as the difficulty in estimating beta. To the contrary, very significant evidence for the clientele effect was found, with little to no influence from market capitalisation and beta, which is as expected. Further investigation into the spread-return relationship is required. If a liquidity premium is not present, foreign investors will favour liquid developed markets above the JSE. This implies that efforts of exchange regulators and the government to decrease illiquidity will lead to foreign portfolio investment inflow into the South African economy. / Dissertation (MBA)--University of Pretoria, 2008. / Graduate School of Management / unrestricted

Western countries, institutions, and people from all walks of land, including Africans, have carried the notion that it is riskier to invest in African countries compared to countries in other continents. This study verified if that notion is empirically established or it is just a mere notion born out of people's imagination and unfounded belief. The study did select one special metal mining company listed on the New York stock exchange from every continent using a systematic random sampling of period five. All these stocks' data were daily data spanning the period 2003-06 - 2020:06 obtained from Yahoo Finance. The said duration was used for the analysis because one of the companies selected for the study only had stock data starting from 2003-06-25. Because of Generalized Autoregressive Conditionally Heteroscedastic (GARCH) ability to model the conditional randomly varying volatility, the study trained several of them for a different order of the GARCH terms σ2, and the order of the ARCH terms ε2 and for different distributions. Based on the AIC and BIC, the GARCH model that best fitted the data was GARCH (1,1), thus order one of the GARCH terms σ2 and order one of the ARCH terms ε2 based on student-t innovation. The study proceeded to estimate the risk measure using three of the approaches (risk metrics, Block Maxima Method under extreme value situation, and Generalized Pareto Distribution (GPD) for the tail ends of the distribution). None of the approaches or methods used in calculating VaR or conditional VaR (ES) of the stocks supported the conventional beliefs and age long-held purported gospel that African counties are the riskiest to invest on earth. In the risk metrics approach, the African stock was second riskiest to European stock. At the same time, in extreme value situations, it was third to European and South American; with GPD, it was third once again to South American and European stock. The study proceeded to verify if this founding were statistically significant. Applying analysis of variance (ANOVA), found that none of the differences established above is statistically significant. Meaning, statistically, the value and conditional value of one's investment that will be at risk is not different based on the investment's continental location. Thus, it is not statistically riskier to invest in one continent than the other.

Bakgrund: Ett SPAC-bolag är ett börsnoterat företag vars enda syfte är att genomföra ett förvärv. Genom förvärvet börsnoteras ett onoterat företag. Intresset för SPACs har ökat på den amerikanska marknaden och år 2020 stod SPAC-bolag för 55% av alla börsnoteringar i USA. Det svenska regelverket på marknaden för börsnoteringar har nyligen förändrats vilket möjliggör skapandet av SPAC-bolag. En viktig anledning till att genomföra studien är för att förstå om SPACs kan användas för att förenkla och förbättra arbetet med börsnoteringar i Sverige för såväl företag, som för finansiella rådgivare och försäkringsgivare. Syfte: Syftet med denna studie är att analysera hur den svenska marknaden för börsnoteringar kan komma att påverkas genom introduceringen av SPACs och analysera de hinder som kan försvåra etableringen. Studien ämnar även att analysera vad SPACs kan skapa för värde till den svenska marknaden för börsnoteringar. Metod: Studien har genomförts med en kvalitativ design. Vidare har en abduktiv ansats använts för att behandla empiri och teori tillsammans i analysen. Data har samlats in från sju stycken semistrukturerade intervjuer med respondenter som har kunskap från den svenska marknaden för börsnoteringar. Slutsats: Den svenska marknaden är en välfungerande och stark marknad. Trots detta finns det vissa möjligheter för SPAC-bolag i Sverige. IPO:s måste anpassas utifrån IPO-fönster. SPAC-bolag är inte påverkade av detta i samma utsträckning och kan då utgöra en alternativ väg till börsen. Vidare kan företag dela med sig av mer information vid SPAC-förvärv vilket reducerar informationsasymmetri och agentproblematik. Det finns även skydd etablerade som minskar risken för investerare. SPACs kan således ha en värdeskapande funktion på den svenska marknaden. Trots dessa fördelar finns det även nackdelar som skulle kunna hämma etableringen av SPACs i Sverige. I Sverige finns redan alternativa marknader som kan utgöra det komplement som SPACs utgör på utländska marknader. Vidare finns argument för att SPACs involverar risk för investerare i form av asymmetrisk information, alternativkostnad och ett okänt förvärvsmål. / Background: A SPAC is a listed company with one purpose, to merge with another company. Through the merger, the other company gets listed on the stock exchange. SPACs have seen an increased interest in the USA and in the year 2020 listings of SPACs amounted to 55% of all IPOs in USA. Due to changed regulations, SPACs are now able to list on the Swedish stock exchange. This study is critical to conduct in order to understand if SPACs can be used to simplify and improve stock exchange listings in Sweden. And if the work surrounding IPOs for companies as well as financial advisors and underwriters would benefit from the introduction of SPACs on the Swedish IPO-market. Purpose: The purpose of this study is to analyze how the Swedish IPO-market can be affected by the introduction of SPACs and to analyze potential hurdles regarding its establishment. The study also aims to analyze value-creating opportunities for SPACs on the Swedish IPO-market. Methodology: The study was conducted with a qualitative design. An abductive approach was used to apply theory and empirical data in the analysis. Data has been collected from six semi-structured interviews with respondents from investment banks in Sweden. Conclusion: The Swedish market is a well-functioning and strong market. Despite this there are some opportunities for SPACs in Sweden. Traditional IPO:s is affected by an IPOwindow which severely limits the ability to do IPO:s during certain periods. When the IPOwindow is closed, SPACs could be another way to the stock market. Companies can share more information when merging with a SPAC which reduces information asymmetry and agency problems. The structure of SPACs also include protection for investors. SPACs can thus have a value creating function on the Swedish market. There are also disadvantages that could be a hurdle for the establishment of SPACs in Sweden. Alternative supportive markets already exist in Sweden. Thus, SPACs may not be needed to the same degree as in foreign markets. SPACs also involve risks for investors in the form of information asymmetry, alternative costs and an unknown acquisition target.

Master‘s thesis is focused on the possibility of financing a company through entering the alternative market of the Prague Stock Exchange Ltd. The alternative market of the Prague Stock Exchange is the START Market, which is suitable for smaller and innovative czech companies. This is about an unregulated market, which means that the conditions of admission conditions and trading rules are set by the stock exchange. The thesis defines the basic starting points, which are connected with the capital market, the market organizer and the initial public offering of stocks (IPO).

I considered on initial public offerings in my thesis. The thesis describes signification of initial public offerings including its advantages and disadvantages, informs about its specifications and recommends to investors, what they should focus on, if they think of such type of investment.

In this diploma thesis a general purpose application was developed in order to analyse economic data emitted by the Prague Stock Exchange. The application was written in the Maple programming language. The purpose of this application is to simulate possible future development of the securities. The main part of the application is a user-friendly graphical user interface.
