Data Freshness & Timezone
Each index is observed at its local market close. Cross-timezone correlations align returns to the later-closing market's trading day.
| Index | Market | Close Time (Local) | Timezone | As Of |
|---|---|---|---|---|
| HSI | Hong Kong | 16:00 | HKT (+08:00) | 2026-04-09 |
| KOSPI | South Korea | 15:30 | KST (+09:00) | 2026-04-08 |
Methodology
Correlations are Pearson rolling correlations of daily log returns, computed over the specified window (30D, 90D, 1Y). Returns are calculated from local-currency index levels at each market's official close time.
For cross-timezone pairs (e.g., HSI in HKT vs KOSPI in KST), returns are aligned to the later-closing market's trading day. This means KOSPI's return on day T is paired with HSI's return on the same calendar day.
Regime classification: high (≥0.60), moderate (0.35–0.59), low (0.15–0.34), negative (<0.15). The 5-year baseline represents the average 90D rolling correlation over 2021–2025.
Known Limitations:
- Timezone misalignment: HSI (HKT) and KOSPI (KST) close at different times. Asian markets close before European/US markets open, so "same-day" correlations reflect lagged information flow.
- Holiday calendars: Different national holidays create gaps in return series. Missing days are excluded from correlation calculations.
- Currency effects: Correlations are computed in local currency. FX movements (e.g., USD/JPY, EUR/USD) are embedded in the correlation but not isolated.
- Regime dependency: Correlations are backward-looking and can shift rapidly during crises. The 30D window captures recent dynamics but may not reflect structural relationships.
