JCI Opens 0.61% Higher at 5,310 This Morning

The Indonesia Stock Exchange’s (IDX) Jakarta Composite Index (JCI) opened higher on Wednesday, 21 October 2026. The index rose 31.96 points, or 0.61%, to 5,310, extending the significant gains recorded in the previous session.

The JCI’s rise was in line with most Asian stock markets, which were also trading in positive territory. The index was supported by gains in several domestic sectors, including energy, basic materials and finance.

However, not all sectors were positive at the market open. Industrials and consumer staples fell.

The JCI’s early movement drew attention after it had climbed more than 5% in trading on Tuesday, 20 October 2026.

Most sectors gain

Wednesday’s opening gains were supported by increases in several sectors. Energy, basic materials, consumer discretionary, finance, infrastructure, property and transport stocks rose.

By contrast, industrial and consumer staples shares came under pressure early in the session.

The divergence shows that the index’s gains were not broad-based across every sector. Nevertheless, advances in most sectors helped keep the JCI in positive territory.

BUKK and IFSH shares surge at the open

Several shares posted significant price gains in morning trading. BUKK led the risers, followed by IFSH and SIPD.

The following shares recorded gains early on Wednesday, 21 October 2026:

• BUKK rose 24.84% to Rp980.

• IFSH gained 24.75% to Rp1,890.

• SIPD rose 24.64% to Rp860.

• TRUK gained 19.90% to Rp6,025.

The gains in these shares coincided with the JCI’s rise at the start of trading. However, the movement of individual share prices does not necessarily reflect the direction of the broader market.

JCI jumped 5.65% the previous day

On Tuesday, 20 October 2026, the JCI closed up 282.28 points, or 5.65%, at 5,278.28.

The increase came as all recorded stock sectors advanced. Despite the sharp rise in the index, foreign investors were net sellers, recording net sales of Rp2.20 trillion.
