La consegna di un sentimento della vita e la vita dell'intelligenza
2018
Nella prima parte, l'A. propone una definizione dell'educazione come consegna di un sentimento della vita: ne va di un'eredità di senso, un ideale di vita buona percepito come valore positivo che consenta al soggetto di abitare eticamente il mondo. Nella seconda parte, è invece proposta una visione della formazione come affinamento dell'intuizione intellettuale, attraverso una pratica noetica che si ispira al metodo fenomenologico. La vita dell'intelligenza è vista come la forma più alta di vita, incremento dell'essere del soggetto e fulcro della personalizzazione dell'esistenza.
Market valuation and acquiring firm performance in the short and long term: Out-of-sample evidence from Spain
2019
We investigate bidder’s short- and long-term performance in periods of high and low valuation market in response to announcements of acquisitions carried out by Spanish listed firms over the period 1991–2016. We find that acquirers of unlisted targets fully react at the announcement date in high valuation periods, meanwhile the underreaction of listed target bidders at the moment of the announcement in low valuation markets is the result of return continuations. In addition, we find that the market reaction do not depend on recent merger history. Therefore, we provide evidence that bidder reaction to acquisitions is not consistent with the predictions of market sentiment (optimism) after c…
Exploring the challenges of remote work on Twitter users’ sentiments: From digital technology development to a post-pandemic era

Médias et sentiment sur les marchés actions européens : influence de la culture nationale
2018
Dans cet article, nous développons une nouvelle mesure du sentiment des investisseurs en Europe à partir d’une analyse de contenus d’articles issus du Financial Times. Dans la lignée des travaux de finance comportementale, nous trouvons que notre mesure du sentiment influence la performance boursière des entreprises difficiles à évaluer et à arbitrer. Par ailleurs, nous montrons que la culture nationale influence le lien entre sentiment des investisseurs et rentabilités boursières. L’impact du sentiment se révèle plus prononcé pour les pays les plus culturellement enclins à des comportements de sur-réaction ou grégaires.
Investor Sentiment or Managerial Overconfidence: The Back Room of Acquisitions
2017
In this study, we investigate bidder performance (both in the short and the long term) in periods of high and low valuation market in response to announcements of acquisitions carried out by Spanish listed firms over the period 1991-2011. We provide evidence that bidder reaction to acquisitions, in both the short and the long term, is not consistent with the predictions of investor sentiment (optimism) after controlling for target type. However, our findings after controlling for bidder market-to-book ratio reveal under reaction in acquisitions of listed targets that is not independent of the market sentiment, since it is greater in hot periods. Finally, the results are not so consistent fo…

Measuring investor sentiment in the stock market
2011
Recently, investor sentiment measures have become one of the more widely examined areas in behavioral finance. A number of measures have been developed in the literature without having been fully validated, and therefore leaving in question which measure should be used for empirical exploration. The purpose of this study is to examine the relative performance of a number of popular measures in predicting stock returns and to test the relative efficacy of a hybrid approach. Using a panel of investor sentiment measures, we develop a new measure of sentiment which combines direct and indirect sentiment measures. Our results show that our composite sentiment index affects the returns of stocks …
