Author Diana Henriques explains the factors behind 1987's stock market crash in her new book "A First-Class Catastrophe: The Road to Black Monday, The Worst Day in Wall Street History." Henriques says she's surprised by how many young investors are unaware of Black Monday, and lessons from this crash should be applied to today's market landscape. Henriques says it is a myth to think the 1987 crash was without consequences, because it revealed dramatic changes that had been occurring in the market over time. Henriques also shares her experience playing herself in the HBO film adaptation to her book, "The Wizard of Lies," about Bernie Madoff.
