I think that you are referring to LTCM ( https://en.wikipedia.org/wiki/Long-Term_Capital_Management https://en.wikipedia.org/wiki/Long-Term_Capital_Management ) which blew up in the late 90s. For others interested, I would strongly recommend the book "When Genius Failed" ( http://www.amazon.com/dp/0375758259 http://www.amazon.com/dp/0375758259 )
