The current research was undertaken to determine the long run performance of Initial Public Offerings (IPOs) listed on the Johannesburg Stock Exchange (JSE) in South Africa. The three year abnormal returns were assessed for IPOs listed between 1995 and 2006 comprising a sample of 229. Using the Buy and Hold Abnormal Return (BHAR) and Cumulative Abnormal Return (CAR) methods, it was found that the IPOs underperformed the market by 50% and 47% for BHAR and CAR respectively. The JSE All Share Index was used as a benchmark. The research also investigated the effect of firm size on IPO performance. The relationship between IPO activity and performance was analysed as well as the performance of IPOs from different sectors. Gross proceeds of the offers were used as a proxy for firm size and it was shown that by splitting the sample into different size groups, there were significant differences between the returns from these groups. There was no relationship found between IPO activity and performance using a linear regression. Using an Analysis of Variance (ANOVA) it was determined that there were significant differences between the performance of IPOs in the different sectors of technology, industrials, financials and mining.

ABSTRACT Prior relative studies document that the mean initial returns of IPOs is significantly positive. Yet, several researches find that the positive abnormal returns appear to be a short-run phenomenon, and the long-run performance of IPOs is poor even negative. Based on a sample of 151 Taiwan IPO firms issued form 1991 to 1996, this study employ the Fama-French three factors model to measure the expected returns of securities. Consistent with predictions, the empirical results show positive short-run returns and a negative long run returns. Meanwhile, there is a negative relationship between institutional ownership and the holding period abnormal returns aftermarket. The conclusion is consistent with the concerns of long-term profitability of institutional investors, as they used to buy low for the benefits of long-term profits. This study also examines the influential factors of institutional ownership. The findings indicate that both firm size and insiders are significantly positive related to institutional ownership. However, neither managerial ownership nor debt is related to institutional ownership. On the other hand, there is significantly negative relationship between stock dividend and institutional ownership, except the second year. At the initial and the first month, cash dividend is negative related to institutional ownership, and industry dummy variable (electronic industry or not) is positive related to institutional ownership. Besides, there is no relationship between cash dividend and institutional ownership, nor was there any relationship between industry dummy variable and institutional ownership. According to the findings, most institutional investors want to maintain the diversification and long-term profits of the portfolio investment.

This study investigated the long-run investment performance of 411 South African IPOs during the period 1992 to 2007. Consistent with historical studies, no evidence of abnormal performance was found on a calendar-time approach using the Fama- French (1993) three-factor model. While the long-run performance did not differ materially, factors such as financial and industrial industry classifications were found to impact after-market performance of IPO portfolios. It was found that large new company issuances within the Financials and Industrials categories produced abnormal returns, but on a collective basis there was no evidence of abnormal performance. In particular, a positive relationship was found to exist between book-tomarket ratios and IPO performance in the financial and industrial sectors, but there was scant evidence on a collective basis. Market conditions were found to have an impact on IPO performance. In periods of market buoyancy, IPOs performed well and in periods of market distress, IPOs‟ performance suffered. The implications of this study are that investors, in making decisions on whether or not to invest in new issues, should not expect to make superior returns to the market over a five-year period by investing in IPOs. IPO performance after the five-year period was not part of the scope for this study and may form the basis for future studies.

Estudos recentes, realizados principalmente no mercado norte-americano, trazem in-dícios de fatores determinantes para o resultado de longo prazo das emissões primá-rias de ações (IPOs, do inglês Initial Public Offerings). Porém, trabalhos com esse enfoque no mercado brasileiro ainda são escassos e inconclusivos, pois utilizam pe-quenas bases de dados e analisam horizontes de tempo de até dois anos. Buscando ampliar a análise de IPOs no mercado brasileiro, o objetivo desta dissertação foi es-tudar os determinantes do desempenho de longo prazo das IPOs realizadas na Bolsa de Valores de São Paulo com horizontes de tempo de três e cinco anos após o pri-meiro dia de negociações. A amostra foi composta por 97 emissões primárias de ações ocorridas entre 2004 e 2012 para o horizonte de três anos e 77 ocorridas entre 2004 e 2010 para o horizonte de cinco anos. O cálculo de retorno de longo prazo seguiu a metodologia de Buy-and-Hold Abnormal Return (BHAR), ajustado ao Ibo-vespa, e os possíveis determinantes do BHAR das IPOs foram submetidos a análises multivariadas através de estimações pelo método de Mínimos Quadrados Ordinários (MQO). Os resultados levam à conclusão de que o desempenho de longo prazo das IPOs brasileiras está positivamente relacionado com: 1) a Idade das firmas, 2) o nível de Governança Corporativa, 3) o Setor e 4) o Desempenho Operacional pós IPO. Pôde-se concluir, também, que o desempenho de longo prazo das IPOs está negati-vamente relacionado com: 1) o Retorno Anormal do Primeiro Dia de negociações, 2) a Quantidade de IPOs realizadas no Ano e 3) o Percentual de Investidores Institucio-nais na emissão primária. Os testes de robustez realizados apontam para uma relação também positiva entre o Crescimento do PIB do período pré IPO com o resultado de longo prazo das ações. / Recent studies, conducted mainly in the North American market, have presented evi-dence regarding decisive factors for the long-run performance of Initial Public Offerings (IPOs). However, the number of similar studies applied in the Brazilian market is yet limited and inconclusive, because they employ reduced databases and short time win-dows up to two years. Seeking to extend the analysis of IPOs in the Brazilian market, the purpose of this study was to explore the determinants of the long-run performance of IPOs held at BM&F Bovespa, with time windows of three and five years after the first trading day. The sample was composed of 97 initial public offerings occurred be-tween 2004 and 2012 for three-year horizon and 77 occurred between 2004 and 2010 for the five-year horizon. The long-run return calculation followed the methodology of Buy-and-Hold Abnormal Return (BHAR), adjusted to the Ibovespa index, and the pos-sible determinants of BHAR related to IPOs were subjected to multivariate analysis using Ordinary Least Squares (OLS) approach. The results lead to the conclusion that the long-run performance of Brazilian’s IPOs is positively related with: 1) Age of the Firms, 2) the level of Corporate Governance, 3) Sector and 4) post IPO Operating Performance. In addition, it was noticed that the long-run performance of IPOs is neg-atively related with: 1) the Abnormal Return of the First Trading Day, 2) the IPO amount held in the year and 3) percentage of Institutional Investors the IPO. Robustness tests were performed, and their conclusions highlighted a positive relationship between GDP growth of previous IPO period with the long-run performance.

Αρκετές μελέτες έχουν στρέψει τη προσοχή τους στη σχέση που συνδέει το R2 με την αξία της επιχείρησης αλλά και στο βαθμό που τα διαφορετικά R2 μπορούν να την επηρεάσουν. Στην παρούσα έρευνα έγινε προσπάθεια να ελεγχθεί η συγκεκριμένη σχέση στις ελληνικές επιχειρήσεις. Για το σκοπό αυτό χρησιμοποιήθηκαν 135 επιχειρήσεις εισηγμένες στο ΧΑ, από το 2004 έως το 2010. Τα αποτελέσματα της εργασίας έδειξαν ότι το R2 συνδέεται με μια αρνητική σχέση με την αξία της επιχείρησης. Τα ευρήματα της έρευνας συμφωνούν με το μοντέλο των Dow and Gorton (1997). Επίσης, βρέθηκε ότι μακροχρόνια οι εταιρείες με υψηλό R2 τείνουν να έχουν υψηλότερες αποδόσεις. / Several studies have focused on the relationship between the R2 and the firm value. They also pay attention on the consequences of the different values of R2 between sectors. In this paper we examine this relationship for the Greek companies listed in the stock exchange. For this purpose, we use a sample consisted of 135 listed companies for the period 2004-2010. The results of this study reveal that R2 is inversely associated with the firm value. This is consistent with the model of Dow and Gorton (1997). Also we found that companies with high R2 have significantly higher returns from the companies with low R2, over a two year period time.

Mergers and acquisitions continue to enjoy importance as strategies for achieving growth, although their success in creating shareholder value remains contested. The aim of this research was to evaluate whether, in the long-run, acquiring companies created or destroyed value by evaluating the differences between pre- and post-acquisition firm performance, using, abnormal share price performance, operating financial performance and intrinsic value performance metrics. This research used a non-representative, judgemental sample of 29 JSE listed firms to conclude that, on average, mergers and acquisitions destroy value within two years post-acquisition, although some evidence was found in support of acquiring firm value creation in the third year after the acquisition. Results indicated a significant -6.62% decline in acquiring firm average cumulative average abnormal return (ACAAR) between 504 trading days before and after acquisition announcement dates. This finding reversed in year three, resulting in a positive ACAAR of 8.76%. Similarly, average intrinsic value (AIV) performance indicated that between one year before and one year after the acquisition, AIV deteriorated with a significant -0.131. However, between year one and two after the acquisition, AIV recovered by 0.112. Overall evidence indicated positive and significant AIV growth of 0.370 between one year before and three years after the acquisition. The research found insignificant results for the pre and post-acquisition evaluation of industry-adjusted cash-flow return on all assets (IACRAA). / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

This study examines the specific ways in which private equity firms influence their portfolio companies to enhance their value, with a focus on the relationship between the level of retained ownership and post-IPO performance. Private Equity firms influence their portfolio companies in specific ways to enhance their value. Private Equity firms are typically limited partnerships, and to realize the value created during the life of the investment, the exit strategy is crucial. An initial public offering is stated as the preferable exit. However, private equity firms usually stay invested in their portfolio companies for up to several years after an initial public offering. Their retained ownership is crucial for underpricing at the IPO and performance post-IPO. This study aims to discover this relationship and to determine its effects. It will contribute to understanding how the portfolio companies' price changes on the first day of trading and their performance, in the long run, is affected by the stake held by the private equity firms. This research will try to clarify the current uncertainty about the effect of underpricing that prevails. It will also fill the existing gap in the academic literature about performance. It can also be potentially helpful for investors. Given knowledge about how retained ownership by PE firms affects underpricing at the IPO and performance post-IPO, this study can help investors to make better investment decisions. However, it should not be seen as investment advice but rather as a contribution to increasing the investor's understanding and knowledge. Publicly listed portfolio companies in the Nordic region constitute the sample for the analysis, and pooled OLS is the econometric method used in this study. We utilized a panel dataset for performance and obtained 2411 unique observations. The long-run performance has been measured as 36 months following the IPO. Our findings indicate a positive relationship between the level of ownership held by the PE firm and both underpricing and performance. These relationships are both statistically significant on the 1% level. Control variables were also included to capture other possible factors that might impact our dependent variables. The positive relationship between the level of ownership held by the PE firm and performance was in line with previous similar research and our expectations. However, the relationship between the PE firm's level of ownership and underpricing was the opposite of what we expected. Previous research has also presented contradictory results, making it difficult to predict the relationship. We hope our results have contributed to clarity regarding underpricing and broadening existing literature about performance for private equity-backed companies.
