Portfolio concentration is investing in assets with specific characteristics within the same sector. Agricultural product industry stocks can be used as an option to form portfolio concentration because they have good growth and performance. This study aims to cluster agricultural product industry stocks listed on the Indonesia Stock Exchange from 2020-2023 using the K-Means clustering algorithm with the Elbow method using the Python 3.10 analysis tool to determine clusters that contain a collection of stocks with the best financial performance. The research resulted in an optimal number of clusters of 3, namely cluster 0, 1, and 2. The cluster that contains a collection of stocks with the best financial performance is cluster 2, which is filled by BISI, LSIP, and DPUM. Cluster 1 has several stocks with relatively good financial performance as it is adjacent to cluster 2, namely AALI, STAA, and CPIN.
