    Cette contribution étudie l’incidence potentielle du caractère familial ou non des entreprises sur leur valorisation boursière, dans le contexte du marché japonais. L’étude empirique porte sur 90 paires d’entreprises cotées, chaque paire étant constituée d’une entreprise familiale, l’autre non familiale, toutes deux de même taille et de même activité. Au total, le marché ne semble pas marquer de forte différence dans son évaluation entre les entreprises familiales et non familiales. Il tend même à mieux valoriser les entreprises non familiales, pour des raisons que l’article s’efforce d’identifier.本論文は、同族会社という企業特性が日本の株式市場の評価に影響を与える可能性を検討している。同一の企業規模、業種の上場90組の同族・非同族企業を対象とした実証調査の結果、金融市場の評価には、同族・非同族会社という企業特性による違いがみられないことがわかった。むしろ、傾向としては非同族会社のほうを高く評価している。その理由については、本論文で明らかにしたい。This paper investigates whether being a family business or not effects a company’s stock market valuation in the context of Japan. Our empirical investigation involved ninety pairs of listed companies, each pair consisting of one family and one non-family business of the same size and from the same industry. We found that there is little difference between the way family and non-family businesses are evaluated by financial markets. The tendency is even to award better valuations to non-family businesses, for reasons that this paper attempts to identify

    The "extreme phenotype approach" applied to male breast cancer allows the identification of rare variants of ATR as potential breast cancer susceptibility alleles

    In oncogenetics, some patients could be considered as "extreme phenotypes", such as those with very early onset presentation or multiple primary malignancies, unusually high numbers of cancers of the same spectrum or rare cancer types in the same parental branch. For these cases, a genetic predisposition is very likely, but classical candidate gene panel analyses often and frustratingly remains negative. In the framework of the EX2TRICAN project, exploring unresolved extreme cancer phenotypes, we applied exome sequencing on rare familial cases with male breast cancer, identifying a novel pathogenic variant of ATR (p.Leu1808*). ATR has already been suspected as being a predisposing gene to breast cancer in women. We next identified 3 additional ATR variants in a cohort of both male and female with early onset and familial breast cancers (c.7762-2A>C; c.2078+1G>A; c.1A>G). Further molecular and cellular investigations showed impacts on transcripts for variants affecting splicing sites and reduction of ATR expression and phosphorylation of the ATR substrate CHEK1. This work further demonstrates the interest of an extended genetic analysis such as exome sequencing to identify very rare variants that can play a role in cancer predisposition in extreme phenotype cancer cases unexplained by classical cancer gene panels testing

    Valorisation par les flux : l'apport des liquidités disponibles

    Valuation is important in many fields of finance, such as corporate finance, mergers and acquisitions or portfolio management. Whereas it is limited for indexed funds management, valuation represents a great issue for an active portfolio management. In the capital-value theory, valuation with dividend discount models shows some insufficiencies, which may be corrected by the use of other flows, the "free cash flow". The empirical study on the french market allowed us to compare how relevant several indicators were, among which some were linked to free cash flows and some were financial ratios. The results show that the indicators we proposed are significant in the market valuation of stocks, and therefore relevant in active management.L'évaluation joue un rôle dans de nombreux domaines de la finance, tels que la finance d'entreprise, les fusions et acquissitions ou la gestion de portefeuille. limitée en cas de gestion passive ou indicielle, la valorisation des entreprises revêt une grand importance pour une gestion active. Dans le cadre du théorème du capital-valeur, la valorisation par les bénéfices présente certaines insuffisances auxquelles nous tentons de remédier en proposant l'utilisation d'autres flux, les "liquidités disponibles". L'étude empirique sur le marché français nous a permis de comparer la pertinence de plusieurs indicateurs liés aux liquidités disponibles avec différents ratios financiers. Il apparaît que les indicateurs que nous avons proposés s'avèrent bien pris en compte dans l'évaluation des actions par le marché, et donc judicieux dans le cadre d'une gestion active
