Why is PT Telekomunikasi Indonesia (Persero) Tbk (TLK) stock moving?
TLK has trended lower over the past month. The close fell from 12.25 on Oct 26 to a low close of 10.40 on Nov 3, a drop of about 15%. The Nov 3 session traded 5.0M shares, roughly 2.3 times the 14-day average of about 2.2M, which points to heavy selling. The stock has since recovered to 11.23 on Nov 10, about 8% above the Nov 3 close, but it remains about 8% below the Oct 22 close of 12.21. Volume in the last three sessions (1.05M to 1.61M) has been below average, so the rebound lacks strong conviction. News in the 14-day window is thin. The main structural item is the Phase 2 partial spin-off of the wholesale fiber connectivity unit to PT Telkom Infrastruktur Indonesia, approved at the Sep 30 EGMS, with a dissenting-shareholder buyback settled Oct 20. The provided data does not quantify the valuation effect of the spin-off. The nine-month unaudited financial statements were filed Oct 30, but the provided text contains no figures, so the earnings trend is unknown. The quantum-safe MoU with BSSN and Peruri is strategically positive but has no disclosed financial impact. Overall, the evidence is mixed: negative price momentum and light recent volume weigh against the stabilization seen in the last week.

About PT Telekomunikasi Indonesia
