Abstract

Les conclusions des travaux de Clark Murphy et Soutar (2004, 2005) et de Nagy et Obenberger (1994) démontrent que les investisseurs individuels ne font pas seulement un arbitrage entre la rentabilité et le risque associé aux titres mais qu'ils évaluent de nombreux critères. L'étude des forums boursiers peut permettre de comprendre comment les actionnaires prennent leur décision et abordent la notion de risque. En finance, a priori, il est admis que les acteurs sont par nature individualistes. L'existence de forums boursiers dans lesquels les actionnaires individuels entrent en contact et échangent entre eux des informations contredit totalement cette idée. Il semble en effet surprenant que des actionnaires individuels décident de participer à un forum boursier sur Internet et choisissent d'y échanger des informations. Les forums d'actionnaires n'ont, à notre connaissance, pas encore été étudiés dans la littérature alors même qu'ils semblent constituer un terrain de recherche très riche. L'objet de cette recherche est d'essayer de dresser un cadre théorique afin d'observer ces forums, mieux connaître les actionnaires individuels et proposer des voies de recherche potentielles.
