Is Sentiment Risk Priced By Stock Market?
2012
International audience; This study tests if the financial markets price the investors sentiment risk. We construct portfolios based upon the stock returns exposure to sentiment. Our results show that the portfolio returns are positively correlated with the exposure of stocks to sentiment. The strategy that consists of buying stocks with the highest exposure to sentiment and selling stocks with the lowest exposure to sentiment generates a significant raw profit. Exploring the sources of profit, we find that neither the traditional risk factors nor the momentum factor can account for the profit. However, we find that the addition of the sentiment risk premium contributes to explain the profit.
L'analyse de la monnaie et de la finance par David Hume : conventions, promesses, régulations
2008
De l’apport de David Hume a l’analyse economique, un aspect est generalement retenu : son approche presumee quantitative de la monnaie. Or, lorsqu’on resitue l’examen des relations monetaires et financieres a l’interieur de son corpus philosophique, il revele d’autres perspectives. Selon Hume, le processus de civilisation institue certaines fictions, qui permettent aux individus de forger un ordre symbolique. Dans une economie de marche, la distinction entre la monnaie – de nature conventionnelle – et les engagements financiers – assimiles a des promesses – est centrale. Alors que les conventions monetaires autorisent de multiples agencements, les engagements financiers doivent etre etroite…
ANALYZING THE EUROPEAN MARKET OF INTEREST RATE SWAP INDICES
2012
The interest rate risk is the most important risk that derives from the OTC transactions, taking into consideration both the notional amounts and the market value of the financial derivatives that relies on interest rate contracts. Open positions on interest rate derivatives represents more than 75% of the OTC market. In the European banking market interest rate swaps prices are strongly dependent on the interbank interest rates. In this paper we want to analyze the behavior of the Eoniaswap indices and their impact on the interest rate swaps between banks.
Long-term memories of developed and emerging markets: Using the scaling analysis to characterize their stage of development
2005
The scaling properties encompass in a simple analysis many of the volatility characteristics of financial markets. That is why we use them to probe the different degree of markets development. We empirically study the scaling properties of daily Foreign Exchange rates, Stock Market indices and fixed income instruments by using the generalized Hurst approach. We show that the scaling exponents are associated with characteristics of the specific markets and can be used to differentiate markets in their stage of development. The robustness of the results is tested by both Monte-Carlo studies and a computation of the scaling in the frequency-domain.
Testing the financial market informational efficiency in emerging states
2012
The Efficient Markets Hypothesis (EMH) has been one of the most influential ideas in the past years and highlights that assets prices incorporate all information rationally and instantaneously. The last financial crisis has led to criticism of this hypothesis. Many practical observations concerning the reaction of investors, but also the mechanisms for the information encompassing in the price of stocks, come to highlight the aspects of 'market inefficiency'. Despite its simplicity, the EMH is surprisingly difficult to test and considerable care has to be exercised in empirical tests. It has attracted a considerable number of studies in empirical finance, particularly in determining the mar…
ESTUDIO DEL EFECTO INFORMATIVO DEL ANUNCIO DE BENEFICIOS TRIMESTRALES
2005
In this research we investigate whether quarterly earnings announcements are informative using awide sample of firms listed in the Spanish Stock Market (SIBE). We study the period comprised between thethird quarterly of 2002 and the fourth quarterly of 2003. We analyse whether abnormal returns are related tothe quarter in which the announcement is released, whether the announcement implies good or bad news forthe firm, the source of the information, the size of the firm and whether the firm is followed by analysts.Results show that quarterly earnings announcements are informative. We also obtain evidence of a possibleuse of insider information in the case of the announcements disclosed in t…
UME Y LA INTEGRACIÓN DE LOS MERCADOS DE CAPITALES EUROPEOS: RELEVANCIA DEL TIPO DE CAMBIO Y LA INFLACIÓN
2007
The aim of this paper is to investigate the effects of the European Monetary Union on the hypothesis of an integrated European Capital Market from January 1993 to December 2004. The extent of the period and the use of Fama and MacBeth [1973]'s methodology for estimating a large number of international asset pricing models that includes an Adler and Dumas [1983] model with and without domestic factor make possible to evaluate this hypothesis as a process towards a full integration. However, our results show that the integration is not a uniform process at all times and for all stocks and recedes in the period 2001-04 with the reappearance of a significant domestic risk premium (diversifiable…
STUDY REGARDING THE MARKOWITZ MODEL OF PORTFOLIO SELECTION
2015
The Markowitz model was introduced through the work of Harry Markowitz (1952) and analyzes the risk and the rentability of a diversified portfolio of securities. In our research, we want to use the Markowitz model in order to identify the structure of the optimal portfolio of risky assets, in other words the efficient portofolio. The study, conducted on three romanian companies from the construction sector, listed on the Bucharest Stock Exchange, leads to the conclusion that the portfolio is illegitimate, so it is necessary to sell the securities of the companies in the absence, procedure known as short sell.

2015
Not every description of our subjective representations of the reality necessarily generates knowledge about the truths of the moment. Our paper presents the conditions a description of the representations of the social reality should meet to be regarded as scientific from a logical perspective.
