Abstract
This research builds prediction models based on
classification algorithms to propose a novel method, which provides research
and practical guidelines and answers research questions we proposed in this
field. Based on extant classification approaches and their limitations, the
proposed method integrates multinational stock index and foreign exchange rate
of main trading countries and builds effectively self-learning models to adjust
behaviors of the medium-term investment dynamically. The proposed approach is unique
in several aspects. First, the classification algorithms approach, a type of
machine learning technologies, automatically generates patterns of medium-term
stock index trend based on big data analysis. The method overcomes the problem
of medium-term investment risks. Second, we evaluate foreign exchange rate to
prove that it is a significant factor for stock index. Third, incorporating
foreign exchange rate into multinational stock index has significant
improvement on accuracy of prediction. This paper utilizes popular machine
learning algorithms such as SVMs to improve the effectiveness of the proposed
method. The results of the evaluation via a medium -term data analysis indicate
that the approach shows advantages in the accuracy of stock index prediction in
comparison with existing methods only considering stock index.
