Description
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.

README excerpt
# Portfolio Intelligence **AI-powered investor intelligence platform for Indonesian equities (IDX)** Portfolio Intelligence transforms raw KSEI (Kustodian Sentral Efek Indonesia) shareholder ownership disclosures into actionable investment insights — helping retail investors track smart money accumulation, understand free-float risks, and validate trading signals with a **Google Gemini-powered finance intelligence agent**. The platform bridges the gap between **market transparency and investor intelligence**. ## Background & Problem Indonesia's capital market has seen explosive retail investor growth in recent years, driven by mobile trading apps and rising financial awareness. However, this growth has come with a structural problem: - **Information asymmetry** — retail investors lack access to institutional-level ownership data - **Finfluencer risk** — speculative stock tips and pump-and-dump schemes cause significant financial harm - **Inaccessible transparency data** — the government publishes ownership data, but it remains raw, pipe-separated, and practically unreadable for most investors ### The Reform That Creates the Opportunity The IDX and KSEI recently lowered the ownership disclosure threshold from **5% → 1%**, publishing monthly snapshots of significant shareholders for every listed company. For the first time, this data reveals *who is accumulating what* — effectively exposing smart money behavior. Portfolio Intelligence is built to unlock this dataset.
