Shanghai Composite rises 0.91%; S&P 500, Nasdaq Composite and Hang Seng post modest gains

For the full trading day on October 28, the Shanghai Composite rose 0.91%, while the S&P 500, Nasdaq Composite and Hang Seng Index gained 0.28%, 0.27% and 0.23%, respectively. These gains reflect each market's own close-to-close comparison window, rather than the same time interval. Cryptocurrency records are stale, and data for the CSI 300 and Hang Seng TECH Index are missing, so broader cross-market performance cannot be inferred from this edition's data.

The same trading date does not mean the same measurement window

All four indices use a close-to-close comparison from October 27 to October 28, but the Shanghai Composite, Hang Seng Index and US markets close at different times. This edition's data support comparisons of gains and losses over their respective trading days. Their shared direction alone does not establish that they responded simultaneously to the same event.
