Jakarta, IDN Times – The Jakarta Composite Index (IHSG) experienced a notable correction in its performance this week, mirroring a decline in overall stock market capitalization. Kautsar Primadi Nurahmad, Corporate Secretary of the Indonesia Stock Exchange (IDX), confirmed that trading data for the period of October 27-31, 2025, closed with varied results, indicating a dynamic week for investors.
“The IHSG saw a change of 1.3 percent, closing at 8,163.875, down from 8,271.722 recorded last week,” Nurahmad stated in an official announcement quoted on Saturday, November 1, 2025. This downturn marks a significant shift from the previous week’s closing figures, drawing attention to market sentiment and underlying economic factors influencing the Indonesian stock market.
Market Capitalization Contracts Amidst IHSG Drop
In tandem with the IHSG’s decline, the total market capitalization on the IDX also contracted significantly this week. Over the five trading days, the IDX’s market capitalization was recorded at Rp14,857 trillion. This figure represents a 2.48 percent decrease compared to the previous week, which had reached Rp15,234 trillion, highlighting a substantial erosion of market value during the period.
Average Daily Transaction Volume Records Highest Increase
Despite the market’s overall correction, the IDX saw a robust increase in its average daily transaction volume. This week, it surged by 3.72 percent, reaching 31.61 billion shares, up from 30.47 billion shares in the preceding week. This demonstrates continued investor engagement even amidst price volatility, suggesting active participation in the market.
Furthermore, the average daily transaction value on the IDX also experienced an uplift, increasing by 1.55 percent to Rp22.63 trillion from Rp22.28 trillion last week. However, the average daily transaction frequency saw a slight dip, decreasing by 1.79 percent to 2.32 million transactions, compared to 2.37 million transactions in the prior week. This mixed performance indicates selective yet higher-value trading activity.
Foreign Investors Record Significant Year-to-Date Net Sell
On Friday, October 31, foreign investors recorded a net buy of Rp1.13 trillion, showing a positive inflow towards the end of the trading week. However, the broader picture for the year remains challenging. Year-to-date, foreign investors have recorded a substantial net sell of Rp47.317 trillion. This figure has remained consistent with the previous week’s tally, underscoring a prolonged period of capital outflow by international players from the Indonesian equity market.
