Two U.S. stock indexes close higher; Hang Seng falls over its comparison window

Both U.S. indexes rise, with the 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, while the Nasdaq Composite gained 1.19%. Both U.S. indexes included in this edition closed higher, with the Nasdaq posting the larger gain. These two indexes alone do not establish whether gains were broad-based across sectors.

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

The Hang Seng Index fell 2.60% between September 30 and October 2, the two consecutive available closing records, while the two U.S. indexes rose between October 1 and October 2. The comparison windows begin on different dates. This observation establishes only a difference in direction within each market's window; it cannot confirm synchronized market movements or shifts in capital.

Shanghai Composite edges higher; latest observation remains September 30

The Shanghai Composite's latest completed trading day was September 30, when it rose 0.31% from its September 29 close. This result predates the latest trading day covered for the U.S. indexes and Hang Seng, so these results cannot be presented together as the performance of all three markets on October 2.
