Jane Street Portfolio holdings
Jane Street is an electronic market maker: exchange-traded funds became its main focus after it began with American depositary receipts. Its trading has since grown beyond ETFs into stocks, bonds and options, and it commits its own capital to help institutions with their trading. Tim Reynolds, Robert Granieri and Michael Jenkins, all former traders at Susquehanna International Group, founded it with Marc Gerstein, an IBM developer. The founders named the firm after Jane Street in Greenwich Village, chosen at random, and it has never been based on that street. Its trading relies on mathematical analysis, and it writes nearly all its own software, trading and risk systems included, in OCaml, a functional programming language. It has no CEO and is led informally by a group of senior executives, and every employee is paid from the firm's collective profits rather than personal trading gains.
