🇰🇷 DART Korea Insider Trading — in English
DART is South Korea's official disclosure system, and it's where every KOSPI and KOSDAQ insider transaction gets filed. It's also entirely Korean-language by default. InsidersAlpha reads DART daily and republishes insider buying and selling activity in English.
Search Korean insider filings without reading Korean or navigating DART directly.
What is DART?
DART (Data Analysis, Retrieval and Transfer System) is the electronic disclosure system run by South Korea's Financial Supervisory Service (FSS). It's the Korean equivalent of the SEC's EDGAR or the EU's national officially appointed mechanisms (OAMs) — every listed company's regulatory filings, including executive and major-shareholder share transactions, are submitted through it. If a director, officer, or major shareholder of a KOSPI or KOSDAQ company buys or sells shares, the transaction shows up in DART.
Why foreign investors struggle with DART
DART's interface, search tools, and the filings themselves are almost entirely in Korean. Even investors who can navigate the site face filings with Korean company names, Korean insider names and job titles, and Korean-formatted transaction details. There's no built-in English translation, no consolidated feed, and no way to filter by signal type (cluster buying, repeat buyers, price-dip purchases) the way MAR Article 19 data can be filtered in Europe. For a non-Korean-reading investor, tracking insider activity at a single company means manually finding its KRX ticker, locating the right filing category, and translating each document.
How InsidersAlpha provides DART data in English
InsidersAlpha monitors DART filings for insider share transactions daily. Each filing is parsed, and company names, insider names, roles, and transaction details are translated and normalized into English — the same structured format used for InsidersAlpha's 15 other European markets. That means:
- Korean insider transactions appear in English, searchable alongside European filings
- Coverage centers on KOSPI 200 constituents and other actively-traded KOSPI/KOSDAQ names
- The same signal detection used elsewhere — cluster buying, repetitive buying, price-dip purchases — is applied to Korean filings
- No need to read Korean, know KRX ticker codes, or navigate DART directly
Frequently asked questions
What is DART (Korea)?
DART (Data Analysis, Retrieval and Transfer System) is South Korea's official electronic disclosure system, operated by the Financial Supervisory Service (FSS). Listed companies and their executives file mandatory disclosures through DART, including insider share transactions by directors, officers, and major shareholders.
Why is DART hard to use for foreign investors?
DART's native interface is in Korean, and most insider transaction reports are filed as Korean-language documents with company names, insider names, and roles that aren't machine-translated. Foreign investors without Korean reading ability have to manually search KRX ticker codes and interpret filings one by one.
How does InsidersAlpha provide DART data in English?
InsidersAlpha monitors DART filings daily, extracts insider transactions from KOSPI and KOSDAQ-listed companies, and translates company names, insider roles, and transaction details into English. Each transaction is normalized into the same format used across InsidersAlpha's 16 markets, so Korean filings can be compared directly with European ones.
Which Korean companies does InsidersAlpha cover via DART?
Coverage focuses on KOSPI 200 constituents and other actively-traded KOSPI and KOSDAQ companies, including large caps such as Samsung Electronics and SK Hynix. Coverage expands as more DART filings are processed.
