Predictability of machine learning techniques to forecast the trends of market index prices: Hypothesis testing for the Korean stock markets

Abstract: The prediction of the trends of stocks and index prices is one of the important issues to market participants. Investors have set trading or fiscal strategies based on the trends, and considerable research in various academic fields has been studied to forecast financial markets. This study predicts the trends of the Korea Composite Stock Price Index 200 (KOSPI 200) prices using nonparametric machine learning models: artificial neural network, support vector machines with polynomial and radial basis function k… Show more

“…Recently, various kinds of AI programs have been developed based on “big data” collected through the Internet of Things. AI programs have been widely used in the manufacturing sector, the information-communications industry [4], and the medical field [5-7]. The development and utilization of AI programs in the medical field are currently entering the stage of commercialization [8,9].…”

“…Pyo, Lee et al [38] investigated the movements of the KOSPI 200 prices applying the ANN and SVM. Their outcomes proved the instability and high variability of machine-learning approaches on market predictions that are explained in [39] and various other studies, by way of hypothesis tests utilizing the KOSPI 200 index market.…”
