In French law, stock exchange damage has a very specific consistency, which is explained, on the one hand, by the originality of the events that are at the source and, on the other hand, by the high technicality of the functioning of the stock exchange. Its manifestations are according to a summa divisio based on the opposition between the harm caused by disinformation and the harm caused by inside information. It shall be substantially repaired in a manner which, in certain respects, may be questioned, in particular in the light of one of the major principles governing the law of civil liability, namely that of full reparation, which seems to be roughed up. From a procedural point of view, its redress through group action appears to be a relatively limited possibility, while its frequently offence-based basis allows the victim to benefit from the due diligence performed by the prosecution authority in the public action.
