Methodology

Data sources

• Prices & indices: KRX end-of-day market data (via FinanceDataReader).
• Investor flows: Korea Investment & Securities open API (foreign / institutional / individual net trading). Shown only when available.

Update schedule

Data pages refresh automatically once per trading day after the Seoul close (18:10 KST). The "as of" date on each page is the last completed session.

Definitions

• 52-week position: where the close sits inside the 252-trading-day low–high range (0% = at the low, 100% = at the high).
• N-day return: close-to-close percentage change over the last N trading days.
• Median 20-day return: sector midpoint across our covered names — a rough gauge of sector momentum.

Conventions

Colors follow the Korean market convention: red = up, blue = down — the opposite of Western charts.
