# KRX Investment Warning Prediction Dataset (OHLCV + 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 and **Korean news text** (title + body), designed for **multimodal anomaly detection / binary classification**.
**Important:** No technical indicators are included, and no normalization/scaling is applied.
- **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 (`0` or `1`)
- **`time_series`**: Price time-series information (OHLCV)
- **`texts`**: Korean news text mapped to the corresponding stock (title + body)
> The exact internal structure of `time_series` and `texts` (e.g., list/dict formats, sequence length, date ordering) follows the dataset schema.
> In general, `time_series` is provided as a fixed-length historical window, and `texts` contains news from the same date (or window period), either concatenated or stored as a list.
### Example (Conceptual)
- `labels`: `0` or `1`
- `time_series`: `[[open, high, low, close, volume], ...]`
- `texts`: `["article1 ...", "article2 ..."]`
## Feature Details
### Price (OHLCV) — `time_series`
- OHLCV is provided as **raw daily bars**.
- **No technical indicators** (e.g., RSI, MACD) are included.
- **No normalization/scaling** is applied.
- **Currency unit:** KRW
- **Volume:** number of shares (not value)
### News — `texts`
- News is mapped to tickers via an **exact ticker-code mapping**.
- **Deduplication** has been applied.
- Each news item includes **title + body** (stored as a single string or list depending on schema).
## 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
