Abstract:
Over the past few years various studies have been conducted to develop an optimum stock market related
portfolio management platform that will assist investors to actively perform the portfolio management process. Risk and
level of investor participation is considered to be one of the challenging aspects identified for optimum portfolio management. Along with portfolio management, stock price prediction is one of the key contributing factors that helps an
investor to make mid and long-term strategic investment decisions. Various concepts are evaluated and studied thoroughly
to determine the most accurate algorithm to implement a stock price-based prediction system. Currently, Colombo Stock
Exchange have identified a desperate requirement of a portfolio management system with prediction capabilities to support
the local and foreign investors to actively engage in trading activities in different stock exchanges in different countries. A
critical study has been conducted using supportive research papers, studying similar applications which are developed so
far and using various requirement elicitation techniques to determine the functional requirements, non-functional requirements, investor requirements and User Interface/User Experience (UI/UX) considerations. The paper further describes
various technological mechanisms implemented and system architectures used to develop the portfolio management and
stock price prediction system. Accordingly, the implementation of Brownian Motion algorithm-based model and LSTM
(Long Short-Term Memory) model are presented in detail by the author. Finally, evaluation and testing results of the completed system and stock price prediction models are presented to prove the successfulness of the completed application
and accuracy of the models implemented
