Indonesia's JCI gains as investors welcome earnings season

The Jakarta Composite Index (JCI) closed on an upward trajectory Friday, buoyed by investor optimism surrounding the release of second-quarter and first-half 2026 financial statements. The index gained 67.32 points, or 1.10 percent, to settle at 6,175.53, while the blue-chip LQ45 index saw a more significant rise of 2.19 percent.

Analysts attribute the JCI's strengthening primarily to robust performance in the banking sector, especially among large-cap issuers. MNC Sekuritas analyst Herditya Wicaksana noted that anticipated foreign inflows into banking stocks, which are currently reporting their earnings, also contributed to the positive sentiment. Historically, July has been a strong month for the JCI over the past decade, often coinciding with the release of these financial reports.

The strengthening of the JCI was driven by the strengthening of banking issuers, especially Big Caps, and by several other Big Cap issuers, as well as an estimated foreign inflow to banking issuers that are currently releasing their financial statements

Elandry Pratama, a capital market observer, emphasized the role of domestic factors, particularly the surge in state-owned banks (Himbara), as the main drivers of the index's growth. He also pointed to recent High Shareholding Concentration (HSC) regulations as a source of positive sentiment, suggesting they enhance transparency and market oversight, thereby improving investor confidence.

Positive sentiment also stems from the latest High Shareholding Concentration (HSC) regulations, which provide a perception of increased transparency and market oversight, thereby helping improve investor market sentiment

From a technical standpoint, Pratama described the rise as a rebound following recent market pressure. Investors are reportedly re-accumulating positions, particularly in highly liquid large-cap stocks within the banking sector. He added that much of the prior negative sentiment had already been factored into stock prices, creating room for recovery when positive catalysts emerge. However, Pratama cautioned that external factors, including global market movements, the U.S. Federal Reserve's interest rate decisions, the rupiah exchange rate, and foreign capital flows, remain crucial considerations for future market volatility.

Analyzing sector performance, the financial sector led the gains with a 2.36 percent increase, followed by the health and non-primary consumer goods sectors. Conversely, the raw materials sector experienced the most significant decline, falling by 0.67 percent, with the industrial and technology sectors also weakening. Trading volume for the day reached 1,985,000 transactions.
