Overenthusiasm during tech bubbles leads to massive overinvestment in infrastructure, like the fiber optic cable laid during the dot-com boom. When the bubble bursts, this infrastructure is acquired for pennies on the dollar, enabling the next generation of companies (like YouTube) to thrive cheaply.
A University of Chicago study revealed that while hedge fund managers' buy decisions are rational, their sell decisions are emotional and destroy value. In fact, randomly selling a different stock in their portfolio would have outperformed their actual sell decisions by 150-200 basis points.
