摘要： In this paper, I revisit Phillips, Wu and Yu's seminal 2011 paper on testing for the dot-com bubble. I apply recent advancements of their methods to individual Nasdaq stocks and use a novel specification for fundamentals. To address a divide in the literature, I generate a detailed sectoral breakdown of the dot-com bubble. I find that it comprised multiple overlapping episodes of exuberance and that there were indeed two starting dates for internet exuberance.
