 I'm Jessica Ettinger, CNBC. Wall Street opens this morning after a rally for stocks yesterday. Fresh all-time highs for the S&P 500 index and the Nasdaq again. Investors believe that Fed Chair Jay Powell indicated interest rates could be cut perhaps this September or the fall. It's all about the latest on inflation this morning. Investors combed through the CPI, the Consumer Price Index, for June out at 8.30 Eastern.
