Selendy & Gay in New York has made a big impression in the securities litigation market since its formation in 2018 with well-established veteran practitioners who previously formed the core of the securities practice at Quinn Emanuel Urquhart & Sullivan, LLP. Over their careers, the practice’ 13 partners have recovered more than $45bn for plaintiffs. Best known for its work in the financial services sector, particularly in cases relating to residential mortgage-backed securities, the firm has broadened its focus to handle securities and structured finance litigation for both plaintiffs and defendants, though in securities litigation its work is overwhelmingly on the plaintiff side. While it is still involved in some high-value RMBS cases, it is also handling matters related to other structured finance instruments, such as a credit-linked notes matter for private equity firm Cerberus Capital Management. Key partners Philippe Selendy and Sean Baldwin, who  is ‘a really good smart lawyer and an honest guy‘, count Financial Guaranty Insurance Company, US Bank and Trilantic Capital Partners among their clients. Up-and-coming partner Andrew Dunlap is also recommended.
