The CPI rose by a less-than-expected 8.5% over the past 12 months after a 9.1% rise in June. read more The rally came in the wake of the first notable sign of relief for Americans who have watched inflation steadily climb.

That is what a soft landing would look like,” said Shawn Snyder, head of investment strategy at Citi U.S. Wealth Management in New York.But one month of slowing inflation is not enough for the Fed to send an all-clear signal, Snyder said.The rally on Wall Street was broad-based, with all 11 S&P 500 sectors rising in a sea of green. Growth stocks (.IGX) rose more than value (.IVX), while Dow transports (.DJT), small caps (.RUT) and semiconductors (.SOX) also rose.The Dow Jones Industrial Average (.DJI) rose 535.1 points, or 1.63%, to 33,309.51, while the S&P 500 (.SPX) gained 87.77 points, or 2.13%, to 4,210.24 and the Nasdaq Composite (.IXIC) added 360.88 points, or 2.89%, to 12,854.81.It was the biggest single-day gain for both the Nasdaq and S&P 500 in two weeks, and for the Dow in three weeks. It was the highest close for the S&P 500 since early May.”(Inflation at) 8.5% is still very high, but there is optimism that perhaps June was the peak,” said Randy Frederick, vice president of trading and derivatives for Charles Schwab.Producer prices data for July on Thursday along with August inflation and employment data for release next month could alter the course of the Fed again, Frederick said.The Fed has hiked its policy rate by 225 basis points since March despite fears the sharp rise in borrowing costs could tip the U.S. economy into a recession.Traders work on the trading floor at the New York Stock Exchange (NYSE) in Manhattan, New York City, U.S., August 8, 2022.
