This article briefly describes the topics "beta coefficient"--a measurement of the price volatility of a company's stock in relationship to the overall stock market--and "market share"--an average measurement for the overall stock market based on a specified group of stocks. It then selectively recommends a database (file) on DIALOG which contains each of the subject concepts and demonstrates a step-by-step procedure for the online retrieval and post-processing of the data using Lotus 1-2-3 (Release 2.2) on an IBM PC/XT. (The specific hardware and software named are intended to serve as a model that can be expanded upon or help influence the thinking of individuals in adapting the idea to other computer systems.) The use of the REPORT command on DIALOG will illustrate how to reformat selected data from multiple records retrieved online into easily read columns for post-processing and ultimately a graph of the results. For those DIALOG databases without the REPORT command, the PARSE option on Lotus 1-2-3 will demonstrate how the post-processing of online data output can be converted into a graph. Essentially, the search results will be manipulated to the extent that actual value will be added to the information retrieved online. The article concludes with a selected list of other sources containing the beta coefficient and market share information. Two examples of online search strategies with explanatory notes and the results of various data manipulations are appended. (BBM)
