In 2008, Rodrigue achieved notability with his model of economic bubbles, charting four phases of a bubble. While the "smart money" has purchased during the earlier "stealth phase", institutional investors begin to buy during "take off". Following media coverage, the general public begins to invest leading to steep rise in prices as "enthusiasm" and then "greed" kick in. "Delusion" precedes the peak.
The chart was widely syndicated during the 2007–2008 financial crisis. Provided by Wikipedia
