Historical Depth
Korean listed companies are required by the Financial Supervisory Service (FSS) to disclose quarterly and annual earnings results via DART (Data Analysis, Retrieval and Transfer System). These disclosures include revenue, operating profit, net income, and forward guidance. Our API processes every earnings filing in near real-time, extracts structured financial metrics using AI, and assigns a signal score based on sentiment, financial impact, and historical market reaction patterns.
Earnings filings are ingested from DART within 15 minutes of publication. Each event is classified, scored, and available via API before market reaction sets in.
Every earnings disclosure is analyzed by LLM to extract sentiment (-1 to +1), short-term impact score (0–100), and key financial metrics — no parsing required.
Aggregate 1-day, 5-day, and 20-day return statistics per event type, derived from 15+ years of Korean market data. Use these baselines for backtest calibration.
