Daily observations
Two U.S. stock indexes edge lower, while the Hang Seng posts a larger decline
Over the full trading day on October 7, the S&P 500 and Nasdaq Composite each fell about 0.22%, while the Hang Seng Index fell 0.62%. All three indexes with available data in this edition moved in the same direction, but this is insufficient to assess the broader market. Data coverage for mainland Chinese A-shares, Hong Kong technology stocks and cryptocurrencies is limited.
Two US Stock Indices Rise; Latest Shanghai Composite Observation Remains September 30
On October 6, the S&P 500 rose 0.58% and the Nasdaq Composite gained 0.45%. The latest available full trading session for the Shanghai Composite was September 30, when it rose 0.31%. These records cover different trading dates, and Hong Kong equity and cryptocurrency data are insufficient to determine whether markets moved in sync.
Two U.S. indexes outgain the Hang Seng; A-share observations remain at September 30
On October 5, the Nasdaq Composite rose 1.05%, the S&P 500 rose 0.66%, and the Hang Seng Index rose 0.28%, all compared with their October 2 closes. The Shanghai Composite's latest full trading day was September 30, when it rose 0.31%. This edition lacks CSI 300 and Hang Seng Tech Index data and usable cryptocurrency updates, leaving insufficient evidence to assess broader links across markets.
Research notes
Strong memory profits have materialized; how long they last depends on product differences and capacity coming online
Samsung’s consolidated earnings guidance and Micron’s financial results show that upstream profits have materialized. But price forecasts, long-term customer contracts and new fab construction plans are not enough to establish that high profits can last. Enterprise demand coexists with purchasing pressure in consumer markets, making the product mix more informative than industry-wide average price increases.
Rate hikes can slow, but tech companies’ cash flows still need checking company by company
Waller signaled flexibility in the pace of rate hikes but did not announce a pause. The available evidence supports continued attention to inflation constraints, but it is insufficient to establish the path of subsequent meetings. Company-level judgments also need tighter limits: being a platform company cannot substitute for checking cash flow, and the sensitivity of reserve yields to interest rates does not directly establish the direction of profits.
