On Monday, October 19, 1987 more than 500 billion dollars of corporate equity disappeared in less than 7 hours. The Dow-Jones Industrial Average lost 508 points in a single day. But this was only the most dramatic day in a week that saw the financial markets literally restructure themselves. This essay examines changes in the way financial markets should be interpreted in the post-crash environment.

Put into the simplest terms, a 5% three-month Treasury bill rate (or a $100 share of stock) does not mean the same thing it did before October 19.
