Abstract

Penelitian ini mengekstrak pola pergerakan harga saham saat pandemi COVID-19 berdasarkan aturan asosiasi dan banyaknya pola teratas k, yang disebut juga pola top-k. Untuk menambang pola top-k, penelitian ini menggunakan Top-K Association Rules Mining algorithm. Tujuan dari penelitian ini adalah untuk memberikan rekomendasi saham yang mudah dipahami dengan menunjukkan korelasi antara saham dengan pergerakan COVID-19. Oleh karena itu, penelitian ini juga berfokus untuk mendefinisikan tipe return dari pergerakan harga saham dan tipe selisih dari pergerakan COVID-19 berdasarkan himpunan fuzzy. Dari data pegerakan COVID-19 dan historis harga saham tahun 2020 sampai tahun 2021 dengan menggunakan Algoritma Top-K Association Rules Mining dengan nilai k = 200, pola pergerakan harga saham saat pandemi COVID-19 menunjukkan bahwa pandemi COVID-19 memengaruhi beberapa pergerakan harga saham pada 4 perusahaan dengan penjualan rugi rendah, yaitu PT Indofarma Tbk. (INAF.JK), PT Unilever Indonesia Tbk. (UNVR.JK), PT Lippo Karawaci Tbk. (LPKR.JK), dan PT Bank Danamon Indonesia Tbk. (BDMN.JK).

This study attempts to discover stock price co-movements patterns during COVID-19 pandemic including association rule and the number of top pattern (k) called top-k patterns. The main goal of this study is to provide a recommendation on stocks it is simple to understand by showing a correlation between stock price and the COVID-19 movement. To do so, this study formulates fuzzy sets of return types of stock price movements and difference types of COVID-19 movements. Based on COVID-19 movements data and historical stock price starting from 2020 until 2021 using Top-K Association Rules Mining with k = 200, the pattern of stock price during COVID-19 pandemic showed that the COVID-19 pandemic affected the movement of several stock prices in 4 companies with low cost sales, PT Indofarma Tbk. (INAF.JK), PT Unilever Indonesia Tbk. (UNVR.JK), PT Lippo Karawaci Tbk. (LPKR.JK), dan PT Bank Danamon Indonesia Tbk. (BDMN.JK)
