Securities Litigation

Fideres have been at the forefront of securities litigation developments across the globe. We provide a range of services to suit the different legal frameworks where we operate: from standardized market efficiency and event studies reports in the US and Australia, to more customized damages assessments produced using different methodologies in the UK and the EU.

In the US, Fideres have extensive experience in evaluating plaintiff specific and class-wide damages for numerous Section 10b, Section 11 and Section 14 class actions. We have built an efficient infrastructure to model and estimate damages in a timely manner (within 24 hours). We also provide preliminary opinions on damages and merits for case evaluation.

Fideres is closely involved in many first of its kind securities litigations outside of the US (UK, Germany, Netherlands, Denmark, etc.). For these jurisdictions (where there is limited or no established precedence), we provide litigation funders and law firms robust and tested support through all phases of litigation, including book-building, data management, evaluation of factual allegations, damages estimation and expert reports.
