The aim of this study is to analyze the influence of the non-performing financing (NPF), financing to deposit ratio (FDR), operational efficiency ratio (OER), and firm size (SIZE) on return on assets (ROA). The object of the research is the Islamic bank in Indonesia and the Islamic bank in Malaysia for the period of 2010–2015. Another aim of this research is to determine if there are differences in the impact of FDR, NPF, OER and firm size on ROA between the Islamic bank in Indonesia and the Islamic bank in Malaysia. The findings show that not all studied independent variables affect the ROA of the Indonesian Islamic Bank and the Malaysian Islamic bank. OER has a negative and significant effect on the Indonesian Islamic Bank’s ROA, while FDR and size have a positive and significant influence on the Indonesian Islamic Bank’s ROA. In the Islamic bank of Malaysia, NPF affects ROA positively, while OER affects ROA negatively. In the Indonesian Islamic bank, independent variables that influence ROA are FDR, OER, and SIZE. In Malaysian Islamic bank, only OER influences ROA significantly. Based on the Chow test, one can conclude that there is a significant difference between the Indonesian Islamic bank and the Malaysian Islamic bank. Regarding operational costs, banks should pay more attention to validation of the costs to be incurred, so there is no need to spend unnecessary costs.

Foreign portfolio investment in developing countries, including Indonesia, plays a crucial role in the economy, where this fund flow can influence exchange rates and stimulate price increases in the stock market. During the COVID-19 pandemic, the volatility of foreign portfolio flows by investors has significantly increased. To anticipate these conditions, the monetary authorities in Indonesia have implemented various monetary policies to address the possibility of more adverse situations. This study examines the impact of the inflow or outflow of foreign portfolio investments and the monetary policies reflected in the 7-day repo rate of Bank Indonesia on the Indonesian stock market. The data were collected from April 4, 2016, to March 18, 2022. The research methodology involves the Non-Linear Autoregressive Distributed Lag and the Markov Switching Regression (MSR) model. The findings indicate that foreign investor portfolio flows influence the Jakarta Composite Index. There is a tendency for domestic investors to analyze the habits of foreign investors. The study also found that monetary policy is not proven to affect the Jakarta Composite Index, while the USD/IDR exchange rate has an impact on the Indonesian stock market. This indicates many companies listed on the Indonesia Stock Exchange have debt in dollars or are paid in US dollars, making them vulnerable to exchange rate fluctuations.
