Who is Mark Baum from The Big Short?

He once said to an interviewer on this topic, “I forget myself sometimes.”

Eisman’s first-born son, Max, died after his night nurse rolled on top of him in her sleep. Eisman and his intimates describe the death of his son as a hugely influential event that affected him in many ways

It did better in 2013, returning 10.8% but still underperforming the market. In July 2014, he announced that he was shutting down the fund, explaining his decision by stating that “making investment decisions by looking solely at the fundamentals of individual companies is no longer a viable investment philosophy.” The fund controlled an estimated $185 million in assets at the time of its dissolution. Emrys Partners stopped operating in mid-2014.
