Futures on the Dow Jones, S&P 500 and Nasdaq point to a volatile start to the upcoming week, driven by earnings from major companies such as :contentReference[oaicite:1]{index=1} and :contentReference[oaicite:2]{index=2}, as well as renewed focus on U.S.–China trade negotiations. On Friday, the S&P rose 1.7% and the Nasdaq 2.1%, but analysts caution that record valuations and narrow tech leadership leave markets vulnerable. Traders are bracing for the September CPI inflation print and key corporate results that might unsettle sentiment.
