Two U.S. indexes close higher; Hang Seng falls over a different comparison window

Both U.S. indexes rise, with Nasdaq posting the larger gain

For the completed trading day on October 2, the S&P 500 rose 0.73% from its October 1 close, and the Nasdaq Composite rose 1.19%. Both indexes gained over the same close-to-close comparison window, with Nasdaq posting the larger increase. This edition's data are insufficient to determine whether gains were broad-based across sectors.

Hang Seng falls, moving in the opposite direction to the U.S. records

The Hang Seng Index closed on October 2 down 2.60% from September 30. This compares the September 30 and October 2 closes, the two consecutive available closing records. Its direction was opposite to that of the two U.S. indexes in this edition, but the Hang Seng's comparison window spans more calendar days. These records therefore do not establish that the markets diverged over the same period.

Shanghai Composite closes slightly higher on its latest completed trading day

The Shanghai Composite's latest completed trading day was September 30, when it rose 0.31% from its September 29 close. This record predates the latest U.S. and Hang Seng closing dates in this edition and shows only that the Shanghai Composite rose slightly over its own comparison window.

What to watch next

• Watch whether the Nasdaq Composite's gain remains larger than the S&P 500's on the next completed trading day.
• Check whether the next pair of consecutive Hang Seng closing records shows a further decline, and verify the comparison dates.
• Once a new completed trading-day record is available for the Shanghai Composite, check whether its direction continues.
• Obtain CSI 300 and Hang Seng TECH Index data and updated cryptocurrency comparison-window data to see whether more assets move in the same direction.
