Genomgång och test av teorier för sannolikheten att aktieåterköp sker, givet ett bemyndigande.

Rakic, Maria, Savén, Sofia January 2013 (has links)
Uppsatsen avser undersöka vilka variabler som kan påverka sannolikheten för att ett aktieåterköp sker givet ett bemyndigande. Under år 2007 fick 93 stycken bolag bemyndigande av bolagsstämman att få utföra ett återköp av aktier. Av dem valde 59 % att utföra det. Vi inleder uppsatsen med att förklara teorier som kan ligga till grund för motiv till att utföra aktieåterköp. Därefter formulerar vi hypoteser som avser pröva teorierna. För att testa hypoteserna med en kvantitativ metod omvandlas de till variabler som testas både var för sig och gemensamt i en logistisk regressionsmodell. De variabler som utformats av teorierna är Kassalikviditet, Book-to-Market, Tidigare återköp, Andel immateriella tillgångar, samt Försäljningstillväxt från föregående år. Resultatet visar att Kassalikviditet och Book-to-Market är statistiskt signifikanta med en signifikansnivå om 10 %. Resterande variabler förkastas. I den gemensamma regressionen är resultatet statistiskt signifikant med signifikansnivå om 10 %. Trots att regressionen förkastar tre av fem variabler i de enskilda regressionerna är slutsatsen att bakomliggande teorier inte nödvändigtvis behöver förkastas då stickprovets omfattning är relativt liten och den valda tidsperioden kort. Därtill finns andra bakomliggande effekter som kan ha påverkat utfallet och som inte har tagits i beaktning i den här undersökningen. Slutsatsen är därmed att resultatet kan vara svårt att generalisera och därmed tillämpa på annan datauppsättning.

Piotroskis F-score : En Grundläggande modell för värdering av aktier

Falk, Robin, Håkansson, Björn January 2013 (has links)
När man väljer att analysera företag, finns det flera olika värderingsmodeller att använda.En av dessa är Piotroskis F-score. Denna modell har mestadels tidigare använts för att analysera företag på den amerikanska marknaden. Nu vill författarna undersöka hur tillämpbar modellen är på den svenska aktiemarknaden och dessutom kombinera denna modell med en Magic Sixes värdering för att öka dess precision. Syftet med denna studie är att undersöka om F-score i samarbete med Magic Sixes kan generera överavkastning och överträffa den svenska aktiemarknaden. Författarna har genomfört en kvantitativ studie med en deduktiv ansats. Data har samlats in med hjälp av databasen Orbis och Dagens Industri. Författarna har upprättat identiska listor för att beräkna företagens F-score och Magic Sixes. Därefter har en beräkning av portföljernas lönsamhet genomförts. Författarnas studie har visat att F-score i kombination med Magic Sixes lyckas slå marknaden under 3 av de 6 studerade åren. F-score har en träffsäkerhet på 65,15% och Magic Sixes har en träffsäkerhet på 58,82%. Modellerna bör inte användas självständigt eller i kombination med varandra som enda grund för ett beslut, men bör ses mer som ett komplement till andra analysmetoder. Slutsatsen är att modellerna kan ge en god indikation på huruvida investerare bör undersöka investeringsobjektet närmare.

Dreaming of Beating the Market : A Fundamental Analysis Study on the Stockholm Stock Exchange

Andersson, Emmy, Draskovic, Darko January 2011 (has links)
The aim of this paper is to test and further improve fundamental analysis models developed by Piotroski (2000) and Rados and Lovric (2009). The improvement seeks to reverse the information in the previous models by taking relative importance and strength of both positive and negative fundamental signals into consideration. The theoretical framework used includes the efficient market hypothesis, fundamental analysis and investing in high book-to-market companies. The Piotroski model, two Rados’s and Lovric’s models and two variations of our model were tested on a portfolio consisting of high book-to-market companies from the Stockholm Stock Exchange during the period 1999-2008. The results show that our EDA Model was the most successful at identifying short selling candidates, as EDA Low portfolio rendered market adjusted returns of -19% on average. Moreover, our EDC model was the best performing at identifying buy-and-hold candidates, with an average annual market adjusted return of 31,5%. The success of our models implies that the market is not using the information captured by them fully and in a timely manner.

Economic Value Added® applied on the American Stock Market : Can the EVA® fundamental analysis increase the returns to a hedge-portfolio strategy with stocks sorted after book-to-market valuation and size?

Bergman, Rickard, Gunnarsson, Philip January 2010 (has links)
In this paper, the popular fundamental analysis model Economic Value Added is tested for any ability to generate returns above that explained by book-to-market effects on American large cap stocks. A zero net-investment hedge portfolio-test was undertaken where the Economic Value Added® fundamental analysis was applied on a sample of large cap stocks, sorted into quintiles after book to market valuation. The portfolio investing in the extreme quintiles gained positive returns between the years 1999 – 2010 equal to an average yearly total return of 7,32 %. During the test-period, the benchmark portfolio constituent of stocks sorted in the same way but without the Economic Value Added® analysis only managed to score returns equaling 2,3 %, adding evidence in favor of the Economic Value Added® analysis. The Economic Value Added also showed a better risk-profile than the benchmark portfolio, measured as the Modigliani Risk-Adjusted Performance over the entire period, further acknowledging the abnormal returns. However, the Economic Value Added® sample portfolios where unevenly distributed regarding number of stocks, foremost in the short-sold part for some years, mitigating the test as strong evidence in favor of the Economic Value Added® analysis. An independent samples t-test also did not reject the null hypothesis. Despite the mixed results of the test, the strength in the specification of sample and choice of method leads us to conclude that that the Economic Value Added® seems like a moderately effective tool for identifying mispriced stocks.

Värdeinvesteringar i Sverige : en enkel strategi för att uppnå överavkastning

Regefalk, Viktor, Runesten, Fredrik January 2018 (has links)
Denna studie undersöker om en enkel värdeinvesteringsstrategi, anpassad för en privat investerare, kan generera överavkastning på den svenska aktiemarknaden. Investeringsstrategin testas under perioden 01.04.2012–31.03.2018. Tre nyckeltal används, book-to-market (B/M), earnings-to-price (E/P) och historisk försäljningstillväxt (SG), för att bilda tre likaviktade portföljer. En tvådimensionell sorteringsmetod används för att sortera urvalet och identifiera undervärderade bolag som väljs in i portföljerna. Tre portföljer skapas den 1 april 2012 och hålls i ett år innan innehavet omfördelas. Portföljernas avkastning riskjusteras med CAPM och Jensens alfa. Två av de tre portföljer som studien undersöker når en statistiskt signifikant överavkastning på enprocentsnivån och säkerställer att investeringsstrategin kan användas för att generera överavkastning.

[en] AN ANALYSIS OF BOOK-TO-MARKET, BANKRUPTCY RISK AND RETURN FACTORS IN THE STOCK BRAZILIAN MARKET / [pt] UMA ANÁLISE DOS FATORES BOOK-TO-MARKET, RISCO DE FALÊNCIA E RETORNO PARA O MERCADO ACIONÁRIO BRASILEIRO

PRISCILLA VANESSA GUERRERO PAZOS 24 February 2016 (has links)
[pt] O presente estudo analisa a relação entre as variáveis Book-to-Market, risco de falência e retornos no mercado acionário brasileiro para um total de 168 firmas da Bovespa no período de Julho 2009 até Junho 2014. Os resultados demonstram que na medida em que a probabilidade de falência e o Book-to-Market aumentam, as empresas brasileiras pagam um prêmio de risco maior. Apesar disto, o fator Book-to-Market quando analisado separadamente, não consegue mostrar uma relação direta com o prêmio de risco, isto é, empresas com alto Book-to-Market (empresas de valor) não necessariamente pagam retornos maiores que as empresas com baixo Book-to-Market (empresas de crescimento). Isto contraria estudos feitos em mercados financeiros desenvolvidos, onde tal relação é estatisticamente significante. / [en] This study analyzes the relationship between the variables Book-to-Market, bankruptcy risk and returns in the Brazilian stock market for a total of 168 Bovespa firms in the period from July 2009 to June 2014. The results demonstrate that as the probability of failure and the Book-to-Market increase, Brazilian companies pay a higher risk premium. Despite this, it was found that the Book-to- Market factor when analyzed separately, is not able to show a direct relationship to the risk premium, that is companies with high Book-to-Market (value companies) do not necessarily pay higher returns than companies with low Bookto- Market (growth companies). This contradicts previous studies done in developed financial markets, where such relationship is statistically significant.

Essays in Empirical Asset Pricing:

Hasler, Mathias January 2021 (has links)
Thesis advisor: Jeffrey J.P. Pontiff / My dissertation includes three chapters on the value premium. In the first chapter, I study whether seemingly innocuous decisions in the construction of the original HML portfolio (Fama and French, 1993) affect our inference on the value premium. I find that the value premium is dramatically smaller than we thought. In sample, the average estimate of the value premium is 0.09% per month smaller than the original estimate of the value premium. Out of sample, however, the difference is statistically insignificant. The results suggest that the original value premium estimate is upward biased because of a chance result in the original research decisions. In the second chapter, I propose an estimate for intangible assets and growth opportunities and examine if this estimate improves book-to-market equity as a measure of value. I find that portfolios sorted on book equity plus the estimate to market equity have lower returns than portfolios sorted on book-to-market equity. The results suggest that intangible assets and growth opportunities diminish book-to-market equity as a measure of value because investors value intangible assets and growth opportunities in an overly optimistic way. In my third chapter, I simultaneously study nine explanations of the value effect to better understand what the dominant value explanation is. I find that duration accounts for most of the value effect and that the eight other explanations account for a negligible part of it. The results suggest that duration is the dominant explanation of the value effect. / Thesis (PhD) — Boston College, 2021. / Submitted to: Boston College.

A influência do índice Book-to-Market e do ROE na explicação dos retornos das ações brasileiras

Cordeiro, Rebeca Albuquerque 09 December 2011 (has links)
Made available in DSpace on 2015-04-16T14:48:45Z (GMT). No. of bitstreams: 1 arquivototal.pdf: 1589704 bytes, checksum: d5351b39767d1d7b0ce73bf049bbcfb5 (MD5) Previous issue date: 2011-12-09 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / This study aimed to analyze the influence of future expectations of book-to-market ratio (B/M) and Return on Equity (ROE) as additional variables to the current B/M ratio in explaining the returns of the Brazilian capital market. Primarily, we investigate the contribution of these three fundamentalist variables in explaining changes on stock returns. Comparatively, was also analyzed the explanatory power of traditional asset pricing models formed with proxies for risk factors: beta, size, B/M ratio, momentum and liquidity. Finally, we verified the consistency of the fundamental variables after combinations of these control variables. The population consisted of all non-financial companies with shares traded on the Bolsa de Valores de São Paulo - BOVESPA from January 1995 to December 2010. The forecast variables were estimated by a linear dynamic panel (ARELLANO, BOND, 1991) with a lag. To analyze the contribution of the variables in explaining the returns of the Brazilian market, we used panel data regressions between annual stock returns and the two groups of explanatory variables. Referring to the fundamentalist variables analyzed, we found that when they were used separately as a multifactor model, the future estimates of the B/M ratio and ROE were not statistically significant and had low explanatory power, suggesting that they have no relevance to the explanation of Brazilian stock returns. The expectations of B/M ratio and ROE were also combined with the current B/M ratio, forming an aggregate forecast variable. It was found that this variable was statistically significant and provided a considerable increase in the explanatory power of models that included it. Thus, Hypotheses 2 and 3 that the future expectations of B/M ratio and future expectations of ROE explain part of the variations on stock returns in Brazil cannot be rejected. The B/M ratio was tested as fundamentalist variable as proxy for risk factor, representing an overlapping variable between the two approaches. The results showed that the B/M ratio was positive and statistically significant in both the fundamental approach and the risk factors approach. Furthermore, when combined in the joint models, it contributed as a risk factor and as a component of the aggregate forecast variable. Thus, the Hypothesis 1 that B/M ratio explains part of changes in Brazilian stock returns cannot be rejected. With respect to the proxies of risk factors, we verified the existence of the B/M effect, a reversed momentum effect and a liquidity premium in the Brazilian capital market. In contrast, there was not found a size effect in the period analyzed. Moreover, the results obtained in this dissertation might contribute to the establishment of investment strategies in the stock market, since the B/M ratio plus the forecasts of the B/M ratio and ROE for the following year were able to explain some of the variations on stock returns for the same period. / Este trabalho teve como objetivo analisar a influência das expectativas futuras do índice book-to-market (B/M) e do Retorno sobre o Capital Próprio (ROE) como variáveis adicionais ao índice B/M atual, na explicação dos retornos do mercado de capitais brasileiro. Inicialmente, buscou-se investigar a contribuição dessas três variáveis fundamentalistas na explicação dos retornos das ações. Comparativamente, também foi analisado o poder explicativo de modelos de precificação tradicionais, formados por proxies para fatores de risco: beta, tamanho, índice B/M, momento e liquidez. Por fim, verificou-se a consistência das variáveis fundamentalistas, após combinações com essas variáveis de controle. A população foi composta por todas as empresas não-financeiras, com ações negociadas na Bolsa de Valores de São Paulo BM&FBOVESPA, no período de 1º de janeiro de 1995 a 31 de dezembro de 2010. As variáveis de previsão foram estimadas por meio de um painel linear dinâmico (ARELLANO; BOND, 1991), com uma defasagem. Para a análise da contribuição das variáveis na explicação dos retornos do mercado brasileiro, foram utilizadas regressões com dados em painel entre os retornos anuais das ações e os dois grupos de variáveis explicativas. Quanto às variáveis fundamentalistas analisadas, verificou-se que, quando utilizadas separadamente, na forma de modelo multifatorial, as estimativas futuras do índice B/M e do ROE foram estatisticamente não significativas e apresentaram baixo poder explicativo, não se mostrando relevantes para a explicação dos retornos das ações brasileiras. As expectativas do B/M e do ROE também foram combinadas com o índice B/M observado, formando uma variável de previsão agregada. Constatou-se que essa variável foi estatisticamente significativa e proporcionou um aumento considerável na capacidade explicativa dos modelos que a incluíram. Diante disso, as hipóteses 2 e 3 da dissertação, de que a expectativa futura do índice B/M e a expectativa futura do ROE explicam parte das variações dos retornos das ações brasileiras, não podem ser rejeitadas. O índice B/M foi testado como variável fundamentalista e como proxy para fator de risco, constituindo uma variável de sobreposição entre as duas abordagens. Os resultados evidenciaram que o índice B/M foi positivo e estatisticamente significativo, tanto nos modelos da abordagem fundamentalista, como nos modelos de fatores de risco. Além disso, quando inserido nos modelos conjuntos, verificou-se a sua contribuição como fator de risco, bem como componente da variável de previsão agregada. Dessa forma, a hipótese 1, de que o índice B/M explica parte das variações dos retornos das ações brasileiras, não pode ser rejeitada. Com relação às proxies de fatores de risco, verificou-se a existência do efeito B/M, de um efeito momento invertido e de um prêmio de liquidez no mercado de capitais brasileiro. Em contrapartida, não se observou a existência de um efeito tamanho, no período analisado. Ademais, ressalta-se que os resultados obtidos nesta dissertação podem contribuir para estabelecimento de estratégias de investimento no mercado de ações, uma vez que a combinação entre o índice B/M atual e as previsões do índice B/M e do ROE, para o ano seguinte, foram capazes de explicar parte das variações dos retornos das ações no mesmo período.

A relação entre intangibilidade, desempenho financeiro e desempenho de mercado

Lauretti, Carlos Marcelo 06 February 2012 (has links)
Made available in DSpace on 2016-03-15T19:30:55Z (GMT). No. of bitstreams: 1 Carlo Marcelo Lauretti.pdf: 1186188 bytes, checksum: ef5b16f19a8df5ffbb1aa67a49379ec3 (MD5) Previous issue date: 2012-02-06 / Fundo Mackenzie de Pesquisa / The index obtained by dividing the equity book value by market value (book-to-market) is found in corporate finance studies to capture performance perspectives that are not present in financial statements. These studies find a negative relation between it and the future financial performance measured by return on assets and a positive relation with market performance measured by return to shareholders, even if the expected return to shareholders is adjusted for non-systematic risk measured by Beta. This research attempts to show that book-to-market value can be characterized as a proxy for companies idiosyncratic intangible assets, and these resources provide sustainable financial performance. The sustainability of financial performance may explain this positive relation between book-to-market value and return to shareholders that are found in these studies, as investors would accept a lower risk premium offered by intangible-intensive companies. If we accept market efficiency hypothesis, by which prices capture all publicly or not available information affecting the value of companies, then intangible-intensive firms present lower risk. This research also brings the discussion that if it is the companies idiosyncratic intangible assets that promote sustainable financial performance then a measure of the construct of intangibility has greater explanatory power for the observed financial and market performance. Strategic resource literature proposes Tobin's Q as an intangibility construct metric. This study shows that the use of Tobin's Q allows the construction of a better performance estimator then book-to-market value, thus confirming that it is intangible assets that offers the best explanation for the companies financial and market performance. This study finds a strong positive relation between intangibility and sustainable financial performance and a negative relation with market performance. / O índice obtido pela divisão do valor contábil pelo valor de mercado do patrimônio líquido (Book-to-Market) é encontrado em estudos de finanças corporativas para capturar perspectivas de desempenho que não estão presentes nos demonstrativos contábeis. Estes estudos notam relações negativas entre ele e o futuro desempenho financeiro mensurado pelo retorno sobre os ativos, porém positivas com o desempenho de mercado mensurado pelo retorno para o acionista, mesmo que o retorno esperado para o acionista seja ajustado pelo risco não sistemático mensurado pelo Beta. O presente estudo procura mostrar que o índice Book-to-Market pode ser caracterizado como uma proxy para os recursos intangíveis idiossincráticos das empresas, e são estes recursos que proporcionam desempenho financeiro sustentável para as empresas. A sustentabilidade do desempenho financeiro pode explicar esta relação positiva entre o índice Book-to-Market com o retorno para os acionistas, já que os investidores estariam dispostos a aceitar um menor prêmio de risco oferecido por empresas intangível-intensivas. Se admitirmos a hipótese de eficiência de mercado, na qual os preços capturam todas as informações disponíveis publicamente ou não que afetem o valor das empresas, então as empresas intangível-intensivas apresentam menor risco. A presente pesquisa traz ainda a discussão de que sendo os ativos intangíveis idiossincráticos das empresas o que promoveria o desempenho financeiro sustentável, então uma métrica do constructo de intangibilidade teria maior poder explicativo para o observado desempenho financeiro e de mercado do que o Book-to-Market. A literatura de recursos estratégicos propõe como métrica do constructo de intangibilidade o índice Q de Tobin. Este estudo mostra que a utilização do índice Q de Tobin permite a construção de melhores estimadores de desempenho que o Book-to-Market, corroborando assim que é a intangibilidade que oferece melhores explicações para o desempenho financeiro e de mercado das empresas. Este estudo encontra uma forte relação positiva entre intangibilidade e desempenho financeiro sustentável e negativa com o desempenho de mercado.
