Abstract
In the economic globalization era, mainly since 2010, ASEAN countries’ financial and investment sectors have emerged to accelerate economic growth. The driving factor for the financial sector’s contribution is the public’s growing interest in financial asset investment products, of which the most chosen one in ASEAN is stocks. However, the COVID-19 pandemic at the end of 2019 affected the growth of stock investments, causing market conditions to be unstable. People held back their interest in investing in stocks because they thought this condition would bring significant losses. Therefore, in this study, the ASEAN-5 stock price index was evaluated to analyze the general stock price conditions for each stock market in the new standard era. The valuation included price predictions and risk of loss using the GBM-MCS and VaR-VC models. The results showed that the GBM-MCS model was more accurate than the GBM model because it had a more stable MAPE value. Referring to the VaR-VC value, the prediction of losses in the ASEAN topfive stock markets for 21–25 April 2022 ranged from 1% to 15%.
