Utilities Indexes

Description

Indexes computed daily in 1993 for DUKE, ENRON and the Utility sector. In the case of Enron and Duke, the index is merely the value of the stock multiplied by a factor appropriately chosen so that the resulting value is exactly 100 on a day chosen to initialize the index. These data are used in the textbook to illustrate the problems with time series regression.
