KRX Investment Warning Prediction Dataset (OHLCV + Technical Indicators + Korean News)
Dataset Summary
This dataset is a test dataset for predicting Investment Warning (투자주의종목) designations in the Korean stock market (KRX). It contains raw daily OHLCV price data, 13 technical indicators, and Korean news text (title + body), designed for multimodal anomaly detection / binary classification.
Important: No normalization/scaling is applied. All values are raw.
- Date range: 2025-07-01 ~ 2025-09-30
- Prediction horizon: whether a stock will be designated as an investment warning within the next 1 trading day
Task
Binary classification:
- Label 0: Normal trading (no investment warning designation within the next 1 trading day)
- Label 1: Investment warning designation (within the next 1 trading day)
Label Alignment
For each (ticker, date=t), set label=1 if the stock is designated as an investment warning on t+1 (the next trading day).
Data Sources
| Source | Description |
|---|---|
| Stock Prices | Daily OHLCV data for KRX listed stocks |
| Investment Warning | KRX investment warning designation history (labels) |
| News | Korean news articles per stock (title + body) |
Dataset Format
This dataset is structured to be used directly with Hugging Face datasets, and consists of three columns:
labels: Binary label (0or1)time_series: Price time-series information (OHLCV + Technical Indicators)texts: Korean news text mapped to the corresponding stock (title + body)

On-Balance Volume |
- No normalization/scaling is applied. All values are raw.
- Currency unit: KRW
- Volume: number of shares (not value)
- Technical indicators are computed with a lookback of 35 days to ensure stable values.
News — texts
- News is mapped to tickers via an exact ticker-code mapping.
- Deduplication has been applied.
- Each news item includes title + body (concatenated as a single string).
Dataset Statistics
- Total Samples: 10,605
- Label Distribution: {0: 10570, 1: 35}
- Sequence Length: 10
- Features per timestep: 18
- Undersampling: Majority class reduced to 10%
Recommended Metrics
Because investment warning events are likely to be rare (class imbalance), the following metrics are recommended:
- ROC-AUC, PR-AUC
- F1 (positive class), precision/recall
- Precision/recall at Top-k (useful for practical detection scenarios)
- (Optional) probability calibration
