Abstract

Investment is an activity to invest assets in certain people or institutions in order to get profits for a certain period of time. Investment can not only be made for the short term, but also be used as saving for the future use. Investment has now become a trend since the pandemic started.

During the current pandemic, it is worsened by the inflation on the value of the Composite Stock Price Index that can fluctuate along with various things. This study aims to review how the public responds in making investments during the current pandemic. The research uses the Support Vector Machine and K-Nearest Neighbors methods. Seeing the use of the Support Vector Machine and K-Nearest Neighbors methods, it can be concluded that SVM is better than KNN, with the SVM accuracy value of 96.84% and that of KNN of 95.74% with a accuracy difference of 1.10% between the two methods.
