Krasting was a trader at Drexel when the 1987 crash happened. The market had tanked the previous week. Everyone was nervous. The Controller called, asked him what he was trading, then told him to sell half on Monday at the open. Krasting did (and so did thousands of other traders, causing the crash.)
To me, there are today many similarities to the market conditions that triggered the 87 crash. These two ring a bell:
Cuban paper and the Hong Kong dollar, to be specific.
