Krisis ekonomi yang terjadi di masa lalu menimbulkan pertanyaan tentang validitasEfficient Market Hypothesis dan mendorong berkembangnya model-model yangdapat memprediksi indeks harga saham. Salah satunya yaitu prediksimemanfaatkan komponen ekonomi yang diketahui mempengaruhi IHSG danmemprosesnya dengan teknik machine learning. Support Vector Machine dikenalmemiliki kemampuan untuk menangani data berdimensi tinggi dan memilikikeunggulan dibandingkan algoritma yang lain. Performa SVM akan dibandingkandengan Artificial Neural Network (ANN) dan algoritma klasik Multiple LinearRegression (MLR). Studi ini diawali mengidentifikasi pengaruh komponenekonomi terhadap IHSG mendatang. Hasil penelitian menunjukkan bahwa SVMmemiliki kinerja paling baik dalam memprediksi harga indeks saham keesokanharinya (t + 1), namun kinerja ANN paling baik untuk memprediksi t + 5, t + 10,dst.

The economic crisis that occurred in the past raised questions about the validity of

the Efficient Market Hypothesis and encouraged the development of models that

can predict the stock price. One of them is prediction utilizing economic

components known to affect IDX composite index and processed by machine

learning techniques. Support Vector Machines are known to have the ability to

handle high-dimensional data and have advantages over other algorithms. SVM

performance will be compared to Artificial Neural Networks (ANN) and the classic

Multiple Linear Regression (MLR) algorithm. This study begins with identifying

the influence of economic component on the future IDX composite index. The

results showed that SVM had the best performance in predicting the next day stock

index prices (t+1), but ANN's performance was better than others for predicting

t+5, t+10, and so on.
