Nasdaq fell 2.86% and Hang Seng rose 1.46% on October 30; Bitcoin edged up over the following 24 hours

Both U.S. indices fell, with the Nasdaq posting the larger decline

On October 30, the latest completed trading day, the S&P 500 fell 1.82% from its October 29 close, while the Nasdaq Composite fell 2.86%. Both indices use the same close-to-close comparison window, confirming that the Nasdaq declined more that day. The data available for this edition are insufficient to determine the contributions of specific sectors or companies.

Hang Seng rose on the same trading date, with a different closing time from U.S. markets

The Hang Seng Index rose 1.46% on October 30 from its October 29 close, moving in the opposite direction to the two U.S. indices on the same trading date. However, Hong Kong and U.S. market figures each use their local closing times. This comparison shows differences in performance over their respective trading days; it cannot establish that the two markets moved in opposite directions during the same period.

Bitcoin's modest gain covers the following 24-hour window

Bitcoin rose 0.31% from October 31 at 00:00 to November 1 at 00:00 UTC, equivalent to October 31 at 08:00 to November 1 at 08:00 Singapore time. This measurement window differs from the close-to-close comparison window for the stock indices on October 30. It therefore cannot establish that Bitcoin diverged from U.S. stocks at the same time or displayed safe-haven behavior.

What to watch next

• Whether the Nasdaq Composite's decline remains larger than the S&P 500's on the next completed trading day.
• Whether the Hang Seng Index and the two U.S. indices continue to differ in direction in the next set of completed trading-day records.
• Once Bitcoin records aligned with the stock market comparison period are available, examine the direction of moves across markets.
