RRI.CO.ID, Jakarta - The Jakarta Composite Index (JCI) on the Indonesia Stock Exchange (IDX) weakened during the lunch break on Wednesday, May 13, 2026. By the close of the first session, the JCI had fallen 124.36 points, or 1.81 percent, to 6,734.54.

The index opened at 6,757.38 and moved volatilely before sliding into negative territory. During the session, the JCI briefly touched a high of 6,787.35, while the low was recorded at 6,726.58.

Head of Retail Research at BNI Sekuritas, Fanny Suherman, had predicted the JCI would open lower than the previous day’s close. “This could test the support level in the 6,600–6,700 range,” she said on Wednesday, May 13.

She explained the decline was influenced by the Morgan Stanley Capital International (MSCI) Review announced on Tuesday evening, May 12. “However, after touching the support level, the JCI technically has the potential to rebound,” Fanny added.

Fanny forecasts the JCI will move within the support range of 6,600–6,700, with resistance expected in the 6,950–7,020 range.

Global index provider MSCI announced the results of its May 2026 stock index review. For the Indonesian capital market, no stocks were added to the MSCI Global Standard Indexes.

However, six issuers were removed from the MSCI Global Standard Index. One of the removed stocks was added to the MSCI Small Cap Index. Meanwhile, 13 stocks were removed from the MSCI Small Cap Index. These changes will take effect at the close of trading on May 29 and become effective on June 1. (Gusti Panji)
