The dot-com period, roughly between 1995-2000, was characterized by extreme investor optimism for Internet-based businesses. This period was also marked by young, bold managers, who made a good deal of money by reaching consumers only over the Internet. Arguably, the dot-com boom was a case of too much too fast and was consequently followed by a crash in March 2000. Jose Menges is a business student at a California State University. For his senior seminar course, he has been asked to compare the stock performance of Internet-based companies with non-Internet-based companies during the dotcom boom-bust period. He collects monthly data on the adjusted close prices from 1999 to 2000 for four companies. Amazon (AMZN) and eBay (EBAY) are chosen to represent the Internet-based companies, whereas Coca-Cola (COKE) and Johnson and Johnson (JNJ) reflect non-Internet companies. A portion of the data is shown below; the complete data set can be found on the text website, labeled Dotcom.
