Fitting Multi-Layer Feed Forward Neural Network and Autoregressive Integrated Moving Average for Dhaka Stock Exchange Price Predicting

Abstract

The stock market plays a vital role in the economic development of any country. Stock market performance can be measured by the market capitalization ratio as well as many other factors. The primary purpose of this study is to predict the movement of the stock market based on the total market capitalization of the Dhaka Stock Exchange (DSE) using autoregressive integrated moving average (ARIMA) models as well as artificial neural networks (ANN). The data set covers monthly time series data of total market capitalization from November 2001 to December 2018. This study also shows the best model for forecasting the movement of DSE market capitalization. The ARIMA (2,1,2) model is chosen from among the several ARIMA model combinations. From several artificial neural networks (ANN) models as a modern tool, a three-layer feed-forward topology using a backpropagation algorithm with five nodes in the hidden layer, one lag, and a learning rate equal to 0.01 is selected as the best model. Finally, these selected two models are compared based on the Root-Mean-Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and Theil’s U statistic. The results showed that the estimated error of ANN is less than the estimated error of the traditional method. Doi: 10.28991/ESJ-2022-06-05-09 Full Text: PDF

CSR and Organizational Performance: A Theoretical Model

“…This study revealed that the community, customers, employees, organizational commitment are the significant factors for improving performance. On the other hand, the corporate reputation also moderates the (Kader et al, 2021;Kabir et al, 2021;Mia et al, 2022;Rubi et al, 2022;Shahriar et al, 2021) relationship between customers to organizational performance, employees to organizational performance, commitment to performance and the employees to performance. Therefore, the corporate social responsibility plays significant role to create organization performance.…”

Financial Performance Evaluation Through Ratio Analysis: A Study on Rural Power Company Ltd.

“…There needs to be more research on performance evaluation for individual organization across the whole power sector (Dong et al, 2021). Financial ratios are used in multi-decision analysis to assess the financial performance of power-producing businesses (Lkuçar & Ifci, 2016;;Faisal-E-Alam et al, 2022;Khan et al, 2022;Mia et al, 2022;Rubi et al, 2022;Zayed et al, 2022a;Zayed et al, 2022b). When evaluating a company's financial success, one can look at either the absolute performance in terms of the scope of operations (balance sheet and income statement) or the relative performance in terms of financial ratios (Katchova & Enlow, 2013;Vibhute et al, 2021;Ali et al, 2020a;Ali et al, 2020b;Chowdhury et al, 2020;F.…”

The Components Impacting Customer’s Bank Determination Choice in Mogadishu, Somalia

“…Consistency throughout the year not only enhances the probability that a product or service will operate as expected, but it also assures on-time delivery. This assists in (Khan et al, 2022a;Khan et al, 2022b;Mia et al, 2022;Rubi et al, 2022)detecting customer experience indicators and potential risks of losing business to competition. Tanzania, which has six fully-fledged Islamic banks, identified the benefits of corporal efficiency, trust, core banking services, and other factors.…”
