Text Mining For Stock Movement Predictions:
A Malaysian Perspective
Author(s)

Abstract
This paper describes a proposed system that extracts keyphrases from online
news articles for stock movement predictions. The proposed system is
implemented and tested on selected active sectors from Bursa Malaysia, a
Malaysian Stock Exchange. The implementation is based on two crucial factors:
firstly, stock related news articles are influential in the sense that they can
influence a buyer’s attitude and subsequently can cause the stocks to move; and
secondly, textual data are considered more superior and contain more
information than numeric data (Cho et al. [1]) because the former not only
allows us to predict future stock prices but at the same time provides us with
reasons as to why it is so.
This paper reviewed investigations on how the online Malaysian news
articles are mined to extract appropriate keyphrases; which are then subsequently
used to predict the movements of stock prices in Bursa Malaysia. The main focus
of this paper is to implement appropriate text mining techniques to extract the
said keyphrases from online news sources. The proposed system is then trained
and tested based on a collection of Malaysian news articles from The Star
Online: Malaysia Business News [2]. The findings indicate that the
implementation is capable of providing valuable keyphrases whether or not
original keyphrases are provided.
