I am new to this site. I am a former Mortgage and Derivatives Trader on Wall Street. I am one of the few ex Wall Streeter’s who has experienced a crisis of conscience. I am an empirical skeptic who is cynical by nature but I have only recently started to sit down and try to figure out why people act stupidly and irrationally. Naseem Taleb, author of the Black Swan & Fooled By Randomness is one of my favorite authors and I truly believe that after all of my years trading it all comes down to random luck not any type of skill.
