Jakarta Composite Index JCI closed up 5.65% at 5,278.89 in Tuesday's (20/10/26) trading. Foreign investors booked a net sell of Rp2.13 trillion in the regular market, or a net sell of Rp2.19 trillion across all markets, while cash and negotiated transactions recorded a net sell of Rp80.33 billion. Accumulated foreign net sell YTD reached Rp118.57 trillion. Technically, JCI rebounded and is approaching its nearest resistance, but remains well below the EMA10, EMA20, and EMA50, indicating the bearish trend remains strong. RSI (14) rose to the 28.67 level, indicating oversold conditions, which opens room for a further technical rebound. If JCI can break back through the 5,317 area, it has the chance of a rebound toward resistance at 5,607 – 5,631. However, if selling pressure continues and JCI breaks through support at 4,999 / 4,980 / 4,907, a break would risk continuing the weakness toward the 4,456 (FR 161.80%), 4,173 / 4,000 area. Investors are advised to remain cautious, apply a selective buy on weakness strategy, and wait for confirmation of a resistance break before accumulating more aggressively. ADVISE: Selective buy on weakness or buy on break. Stockpick: ANTM, BBCA, BUKA, TINS.
