The book makes an argument that booms and busts are not random and can therefore be identified. It's structured similarly to how the course at Yale by Mansharamani has been taught. The first third of the book focuses upon various theoretical and disciplinary lenses useful in the study of booms and busts. The second third of the book evaluates historical cases of financial booms and busts via those lenses. The final third of the book summarizes the findings from part two and develops a profile for a typical financial bubble. The book concludes with a framework for thinking about and identifying forthcoming financial extremes and a discussion of various candidates for the "next bubble."
