Indonesia’s capital market is experiencing a rapid surge in retail investors, many of whom rely on social media and “finfluencers” for investment advice, leading to numerous cases of fraud and speculative trading. At the same time, the Indonesia Stock Exchange and KSEI have recently introduced a major transparency reform by publicly releasing monthly data on shareholders owning more than 1% of listed companies, lowering the disclosure threshold from the previous 5%. While this dataset provides unprecedented visibility into market ownership, it remains difficult for most investors to analyze. Portfolio Intelligence transforms this raw disclosure data into actionable insights by detecting accumulation patterns, ranking smart-money investors, and using a Google Gemini-powered finance intelligence agent with tool-based search and analytics to validate signals and explain market catalysts.
