"Och det där mönstret är i sin patologi pinsamt enkelt. Först infinner sig detta till synes *nya* på den ekonomiska scenen. Det lockar till förhoppningar, drömmar och spekulation. Priset går upp. Detta lockar nya köpare. Priset går upp igen. Fler spekulanter flockas. Priset går upp ännu mer, och så vidare. Precis som i tulpansvindeln skapar alltså bubblan sin egen uppåtrörelse, oberoende av de faktiska värdena. Kurvorna går så vackert i taket."

In a matter of a few days, the price of tulip bulbs was slashed by 96%!
