November 6 Close: Nasdaq Rises, Shanghai Composite and Hang Seng Fall

Both US Indices Rise, with the Nasdaq Posting the Larger Gain

On November 6, the latest complete trading day, the Nasdaq Composite rose 1.09% from its November 5 close, while the S&P 500 gained 0.31%. This edition's data confirms that both indices rose by different amounts, but without individual stock contributions or sector performance data, it cannot establish which companies drove the gains.

Shanghai Composite and Hang Seng Fall; Cross-Market Comparisons Must Account for Timing Differences

On November 6, the Shanghai Composite fell 1.10% from its November 5 close and the Hang Seng Index declined 1.27%, moving in the opposite direction to the two US indices on the same date. Each market uses its own local close-to-close measurement window, but Asian markets close before US markets. This divergence therefore cannot be interpreted directly as market reactions occurring at the same moment.
