The recent meltdown on Wall Street and in other financial centers serves to highlight the flip side of opportunity and potential. On 29 September 2008, following some modest sell-offs in stock markets in Asia, the Dow Jones Industrial Average plunged by 778 points, a 7% drop over the course of a single day. In just over six hours, more than $1.2 trillion was wiped off the value of US industry -- the first time a daily loss exceeded $1 trillion and the blackest day since the 1987 Wall Street crash.
