Same Comparison Dates, Different Closing Times

The comparison windows for all four stock indices run from October 23 to October 26 and overlap. However, the Shanghai Composite, Hang Seng Index and two US stock indices close at different times, so their measurement windows do not align exactly. This edition's data can only confirm that each rose within its respective window; they cannot establish that the indices moved in sync or shared a common driver.
