Data Warehouse Software Used in the Decisional Process on the Capital Market

Capital market provides strong opportunities for investors who know how to adopt favorable decision in real time. The decision to invest on the capital market involves deep knowledge on the mechanisms and characteristics of this market, the factors that determine the consequences of investment decisions and the performance of allocated capital. As the data volume related to the capital market evolution reaches a sizable amount, we consider appropriate to propose a multidimensional data structure that would be able to assist the investor in analyzing the shares in which he would like to invest. This structure could be designed by using an accessible support system, as the dimensional model proposed is valid for any DSS based on OLAP.

Regression Models Applied in the Analysis of the Romanian Capital Market

Abstract The analysis of the activity of the Bucharest Stock Exchange can be realized with the help of a complex system of indexes. Out of these, an especially important role in the creation of a real image on the performances of the main stock exchange institution of Romania is held by the BET (Bucharest Exchange Trading) index. One of the factors with significant influence on the value of BET is the stock exchange capitalization. This is an indicator on the potential of a stock exchange which reflects the market value of listed companies and can be determined as sum of the product between the number of shares issued by each listed entity and its corresponding market price. This paper describes the analysis of a data series (daily frequency) regarding the value of BET index and stock exchange capitalization in 2012. The 250 terms of the series subjected to econometric analysis are collected from official sources.

Using the Regression Model in the Analysis of Financial Instruments Portfolios

Abstract An especially important aspect in the analysis of performance for financial instruments is the determination of the correlation existing between the evolution of its performance and the overall trend of the capital market. The determination of such econometric model ensures, for capital investors, a series of information necessary in order to establish their behaviour in the subsequent periods. Within the research, the regression econometric model was used with the aim to evaluate the relation between the performance of a portfolio of financial instruments and the evolution of the corresponding capital market. The portfolio is made of ten financial titles, quoted on the main market of the Bucharest Stock Exchange. The dataset which offers the source data for analysis includes details regarding the daily evolution in 2012 of the selected shares.
