It is widely agreed that the Nasdaq during the dot-com era 20 years ago was a full-fledged stock market bubble. Recently, the US stock market according to many metrics has become significantly more speculative and overvalued than it was at the dot-com peak 20 years ago. In both instances, a very broad subset of stocks became so highly valued that speculation in them had to be untethered from all fundamentals: the essence of what we call a "pure price-chasing bubble." This paper, drawn from a book in progress, examines the history of stock markets for comparable pure price-chasing bubbles, finding nine or so which have ever reached such a speculative extreme, with an over-the-counter market in Kuwait in the early 1980s called the "Souk al-Manakh" representing the most extreme example. Based on my personal exposure to this Souk al-Manakh almost 40 years ago, I describe this anatomy and thereby make transparent the recurrent dynamics - on the way up and on the way down - of these greatest asset bubbles in human history. When one applies this framework to the current US stock market, one sees that the stock market in the US today will likely follow the disastrous path of the dot-com market.

The dominant postwar tradition in economics assumes the utility maximization of economic agents drives markets toward stable equilibrium positions. In such a world there should be no endogenous asset bubbles and untenable levels of private indebtedness. But there are. There is a competing alternative view that assumes an endogenous behavioral propensity for markets to embark on disequilibrium paths. Sometimes these departures are dangerously far reaching. Three great interwar economists set out most of the economic theory that explains this natural tendency for markets to propagate financial fragility: Joseph Schumpeter, Irving Fisher, and John Maynard Keynes. In the postwar period, Hyman Minsky carried this tradition forward. Early on he set out a "financial instability hypothesis" based on the thinking of these three predecessors. Later on, he introduced two additional dynamic processes that intensify financial market disequilibria: principal-agent distortions and mounting moral hazard. The emergence of a behavioral finance literature has provided empirical support to the theory of endogenous financial instability. Work by Vernon Smith explains further how disequilibrium paths go to asset bubble extremes. The following paper provides a compressed account of this tradition of endogenous financial market instability.
