The stocks are one of a variety of securities that are traded in general through the stock exchange. One sector that is quite large in the Indonesian capital market is banking stocks. Banking stock prices are often used by economic analysts as a reflection of the Indonesian economy, this is because banking stock prices are one of the largest sectors in the Indonesian capital market. However, since the discovery of the Covid-19 outbreak in Indonesia in March 2020, banking stock prices have fallen drastically. Since then, the movement of banking stock prices has continued to fluctuate and be uncertainty. This study will forecast banking stock prices using BBCA, BMRI, and BBRI stock price data by adding an intervention variable, namely the time the Covid-19 outbreak was discovered in Indonesia. In this study, we will compare hybrid model of the univariate time series and Artificial Neural Network known as ARIMAX-NN with hybrid model of the multivariate time series and artificial neural network as VARX-NN. The results of this study show that hybrid VARX-NN model produces a smaller RMSE value than ARIMAX-NN model in BBCA, BMRI and BBRI. © 2022 Author(s).
股票是通过证券交易所交易的多种证券中的一种。银行股是印尼资本市场中相当大的一个板块。银行股价格经常被经济分析师用来反映印尼经济，这是因为银行股价格是印尼资本市场上最大的板块之一。然而，自2020年3月在印度尼西亚发现新冠肺炎疫情以来，银行股价格大幅下跌。此后，银行股价格走势持续波动，充满不确定性。本研究将使用BBCA, BMRI和bbi股价数据，通过添加干预变量，即在印度尼西亚发现Covid-19爆发的时间，预测银行股价。在本研究中，我们将比较单变量时间序列和人工神经网络的混合模型ARIMAX-NN与多变量时间序列和人工神经网络的混合模型VARX-NN。本研究结果表明，混合VARX-NN模型在BBCA、BMRI和bbi中产生的RMSE值小于armax - nn模型。©2022作者。
