Correction — 22 October 2026: The original KOSPI decline of 4.54% is corrected to 2.62% for October 8. The Nasdaq rose 0.64% on October 9 rather than falling 0.63%. The earlier same-day comparison and inferred hedging narrative are withdrawn. This is a retrospective review using daily history retrieved on 2026-10-22, not a live report or a reconstruction of every quote available at original publication.
Gold was not the only asset that gained
Gold futures rose 1.43%, the S&P 500 rose 0.59%, and the Nasdaq rose 0.64% in the October 9 daily observations. Gold’s gain alongside equity gains does not identify who bought it or whether those purchases were hedges. Those questions require positions or flow evidence beyond closing prices.

Different dates weaken a regional-stress inference
The Korean observation in the weekend snapshot was from October 8, while the US equity and gold observations were from October 9. Treating them as simultaneous makes an apparent divergence easier to overinterpret. Even with dates aligned, different asset returns do not identify investor motives. A useful comparison begins with each asset’s own previous session and then states the limits of the cross-market timing.
Method and limits
Percentage changes use (value ÷ previous available daily value − 1) × 100, before rounding. Yield changes use the difference in percentage-point quotes multiplied by 100 to obtain basis points. Index levels are in points; futures quotes are in US dollars per barrel for WTI and per troy ounce for gold.
Each linked Yahoo Finance history is the data source for that row. These provider observations have not been independently checked against exchange settlement records. The futures series can change its referenced contract over time and should not be treated as the return on a continuously held investment. A date shared by two markets does not make their closing times simultaneous.
The earlier news-based explanations are omitted because their relevance to these measured moves was not established. For the calculation workflow and trading-session examples, see How to Read Daily Market Returns Without Mixing Trading Sessions.
