The Indonesia Stock Exchange (IDX) reported a marginal downturn in the performance of its benchmark Composite Stock Price Index (IHSG) for the trading week from March 23 to March 27, 2026. The IHSG closed at 7,097.057, marking a slight decrease of 0.14 percent from its previous week’s closing position of 7,106.839. This modest retreat indicates a period of consolidation or cautious investor sentiment within the stock market.
Echoing the movement of the primary index, the overall market capitalization of the IDX also experienced a minor contraction during the week. Kautsar Primadi Nurahmad, Corporate Secretary of the IDX, stated that the market capitalization diminished by 0.24 percent, settling at IDR 12,516 trillion, down from IDR 12,547 trillion recorded in the preceding week. This suggests a slight reduction in the aggregate value of companies listed on the exchange.
Despite the slight dip in both the IHSG and market capitalization, several key trading metrics revealed increased activity. The average daily transaction frequency on the IDX notably rose by 9.01 percent, reaching 1.73 million transactions, up from 1.59 million transactions in the prior week. Kautsar highlighted this uptick in engagement in a statement released on Saturday, March 28.
Furthermore, the average daily transaction value on the Indonesia Stock Exchange also experienced a significant surge. It climbed by 15.27 percent to IDR 23.33 trillion, a substantial increase from IDR 20.24 trillion recorded during the previous week. This robust growth in value indicates that larger sums of capital were deployed, contributing to a more dynamic trading environment despite the index’s decline.
However, a closer look at the market’s activity reveals a contrasting trend in volume. While transaction frequency and value increased, the average daily transaction volume for the week actually decreased by 4.81 percent. It totaled 28.31 billion shares, down from 29.74 billion shares in the preceding week. This divergence suggests that although transactions were more frequent and involved higher values, the sheer number of shares traded was slightly lower.
A persistent factor influencing the week’s market dynamics was the activity of foreign investors. By Friday, March 27, foreign investors registered a net selling position of IDR 1.76 trillion. This contributed to a substantial year-to-date net selling figure for 2026, totaling IDR 30.88 trillion, underscoring the significant influence of overseas capital flows on the IDX’s performance.
