JCI Suddenly Jumps 1%, Here's Why

The Jakarta Composite Index (IHSG) soared more than 1% in trading on Friday (14/8/2026). However, the index’s gain this time did not yet reflect a broad market rally, as only one stock was the main driver of the IHSG.

Based on IDX Mobile data at 14:55 WIB, the IHSG stood at 6,385.81, up 84.04 points or 1.33% from the previous close of 6,301.77.

Interestingly, the IHSG’s gain was heavily supported by Bayan Resources (BYAN). BYAN shares were recorded surging 20% to Rp14,400 per share, hitting its daily upper trading limit.

BYAN’s rise contributed approximately 43.25 points to the IHSG, or more than half of the index’s total gain of 84.04 points.

With a market capitalisation of around Rp480.1 trillion, the surge in BYAN shares had a significant influence on the IHSG’s movement.

Besides BYAN, several other stocks also made positive contributions, such as VKTR Teknologi Mobilitas (VKTR) with 5.21 points, Amman Mineral Internasional (AMMN) 4.28 points, Telkom Indonesia (TLKM) 3.13 points, and Dian Swastatika Sentosa (DSSA) 2.91 points.

On the other hand, a number of stocks actually held back the IHSG’s advance. Bank Central Asia (BBCA) was recorded reducing the IHSG by 2.49 points, while Barito Renewables Energy (BREN) was the biggest drag with a negative contribution of 2.62 points.

This condition shows that today’s IHSG gain was not yet fully supported by large-capitalisation stocks broadly. In fact, the financial sector was recorded weakening 0.08%, even though the IHSG rose 1.33%.

Of the 11 sectors recorded, the majority were in positive territory. The energy sector was the strongest with a gain of 6.96%, followed by primary consumer goods 1.36%, raw materials 1.33%, non-primary consumer goods 1.05%, and technology 1.03%.

Meanwhile, the healthcare sector fell 0.53% and utilities weakened 0.89%.

Overall, 338 stocks rose, 294 stocks fell, and 331 stocks were unchanged. Total trading volume reached 24.77 billion shares with a transaction value of Rp8.76 trillion.
