Both US Indices Post Small Declines

For the completed September 29 trading session, the S&P 500 fell 0.17% and the Nasdaq Composite declined 0.09% from their September 28 closes. Both indices moved lower, with the Nasdaq recording the smaller decline. These two indices alone do not establish how individual sectors performed.

Shanghai Composite and Hang Seng Move in Opposite Directions

For the completed September 29 trading session, the Shanghai Composite rose 0.18% and the Hang Seng Index fell 0.48% from their respective September 28 closes. The A-share and Hong Kong equity indices included in this edition moved in opposite directions. Coverage is limited, however, and does not support conclusions about the strength or weakness of all sectors across the two markets.

HKEX Reports Listing Developments as Hang Seng Closes Lower

In an original post on September 29, HKEX said it welcomed six newly listed products that day. A separate original post said the Hong Kong SAR Government had issued digitally native green bonds in multiple tranches and currencies, with listing expected on September 30. Meanwhile, the Hang Seng Index closed September 29 down 0.48%. The listing developments and index performance are observations at different levels; the available evidence is insufficient to establish a causal link.
