Flooring Guide by Cinvex – , JAKARTA — The Jakarta Composite Index (IHSG) delivered a stellar performance in November 2025, repeatedly hitting all-time highs (ATH). This impressive market rally was accompanied by a significant influx of foreign capital, with funds largely channeled into shares of major players such as PT Bank Central Asia Tbk. (BBCA) and PT Bumi Resources Minerals Tbk. (BRMS).
According to data from the Indonesia Stock Exchange (IDX), the IHSG demonstrated robust growth in the past trading week, spanning November 24-28, 2025. It surged by 1.12% week-on-week, closing at 8,508.7, a notable increase from the previous week’s close of 8,414.352. This upward momentum underscores the prevailing positive sentiment across the Indonesian capital market.
The IDX’s market capitalization also experienced a substantial boost, climbing by 1.53% to reach Rp15,626 trillion, up from Rp15,391 trillion just a week prior. This expansion reflects growing investor confidence and the overall health of the exchange, further solidifying Indonesia’s position as an attractive investment destination.
“The most significant increase was observed in the average daily transaction value of the IDX, which soared by 41.87% to Rp30.31 trillion, compared to Rp21.37 trillion in the preceding week,” stated Kautsar Primadi Nurahmad, Corporate Secretary of the IDX, in a written statement issued on Friday, November 29, 2025. This surge in trading activity highlights heightened investor engagement and liquidity within the market.
Looking at the broader monthly picture, the IHSG shone brightly throughout November 2025, registering a commendable 4.22% gain. This performance has cemented the index firmly in the green zone, with its year-to-date (YTD) growth reaching an impressive 20.18% since the first trading day of 2025, signaling a sustained bullish trend.
The IHSG’s record-breaking spree continued, with the index not only reaching new highs but shattering previous ones. It achieved an all-time high closing level of 8,602.13 during last week’s trading on November 26, 2025. Furthermore, the IHSG hit an all-time high intraday level of 8,622.27 just one day later, on November 27, 2025, showcasing the market’s strong upward trajectory.
Parallel to the IHSG’s stellar performance, foreign capital has been pouring into the Indonesian stock market. Data reveals that foreign net buy reached a substantial Rp17.9 trillion in November 2025, indicating strong international investor appetite for Indonesian equities and their confidence in the market’s potential.
A closer look at specific stocks reveals the primary beneficiaries of this strong foreign inflow over the month. Shares of PT Bank Mandiri Tbk. (BMRI), for instance, attracted foreign net buy totaling Rp3.55 trillion throughout November 2025, making it a top target for international investors.
Following closely, PT Bank Central Asia Tbk. (BBCA) shares recorded a foreign net buy of Rp2.52 trillion, while PT Bumi Resources Minerals Tbk. (BRMS) saw an impressive Rp2.79 trillion in foreign net buy during the same period. These figures underscore the robust demand for leading Indonesian companies.
The positive trend extended to other key players, with PT Barito Renewables Energy Tbk. (BREN) registering a foreign net buy of Rp1.79 trillion over the month. Similarly, PT Astra International Tbk. (ASII) garnered Rp1.05 trillion in foreign net buy, highlighting a broad-based interest across diverse sectors of the Indonesian economy.
Farell Nathanael, an Equity Research Analyst at OCBC Sekuritas, attributed this vigorous inflow of foreign funds for the remainder of the year to several contributing factors. The economic landscape and government policies are playing a crucial role in shaping investor decisions and market direction.
“Bank Indonesia continues to implement interest rate cuts, which incentivizes a shift of capital towards riskier assets compared to those deemed less risky,” explained Farell some time ago. This monetary policy creates an environment where equities become more appealing, driving investment into the stock market.
Another significant factor is the government’s ongoing stimulus initiatives, designed to bolster economic activity. Coupled with the robust fundamentals of Indonesian issuers, these measures continue to attract the attention and investment of foreign capital, signaling a positive outlook for corporate performance.
Reinforcing this optimistic sentiment, Nafan Aji Gusta, Senior Investment Information at Mirae Asset Sekuritas, had previously forecast that the strong trend of foreign fund inflows, which began in October 2025, would persist until the end of the year. This suggests a sustained period of growth and positive market dynamics.
“Furthermore, there are expectations surrounding the phenomena of ‘window dressing’ and the ‘Santa Claus rally.’ Consequently, the IHSG is poised to remain bullish. Historically, November and December have proven to be bullish months, a trend that could potentially extend into January of the following year,” Nafan added, highlighting seasonal market patterns.
For context, “window dressing” refers to the strategy employed by investment managers to enhance their portfolio performance before reporting to investors, often involving strategic buying. Meanwhile, the “Santa Claus rally” describes the common trend of rising stock prices typically observed during the last week of December, further buoyed by the government’s fiscal stimulus policies aimed at boosting economic growth.
Beyond these factors, corporate actions such as share buybacks by issuers also contribute to market strength. The market has also shown appreciation for the solid performance reported by issuers in the third quarter of 2025, reinforcing investor confidence and contributing to the overall positive momentum.
Summary
The Jakarta Composite Index (IHSG) delivered a stellar performance in November 2025, repeatedly hitting all-time highs and achieving a 4.22% monthly gain, pushing its year-to-date growth to an impressive 20.18%. This strong market rally was driven by a significant influx of foreign capital, with net buys totaling Rp17.9 trillion. Top beneficiaries of this foreign investment included PT Bank Mandiri Tbk. (BMRI), PT Bumi Resources Minerals Tbk. (BRMS), and PT Bank Central Asia Tbk. (BBCA).
Analysts attribute this vigorous foreign fund inflow to several factors, including Bank Indonesia’s interest rate cuts which encourage a shift to riskier assets like equities. Government stimulus initiatives, robust fundamentals of Indonesian issuers, and expectations of year-end “window dressing” and a “Santa Claus rally” are also contributing to the sustained bullish trend. The IDX’s market capitalization and daily transaction values also saw substantial increases, reflecting growing investor confidence.
