Dow Gains 556 Points as Producer Prices Post Biggest Rise Since 2022
September PPI rose 1.3% from August and 6.3% over 12 months, while AI-linked shares moved in different directions.

U.S. stocks finished higher Thursday, Oct. 15, after major indexes recovered from early losses. The Dow’s advance outpaced modest gains in the S&P 500 and Nasdaq as producer prices recorded their sharpest monthly increase since March 2022, with energy driving much of the rise.
At the 4 p.m. ET close (20:00 UTC), the Dow Jones Industrial Average stood at 52,177.69, up 556.21 points, or 1.1%. The S&P 500 finished at 7,744.06, a 0.3% gain, and the Nasdaq Composite ended at 26,713.03, up 0.1%.
The indexes’ different gains did not establish a broad move away from artificial intelligence stocks. The Dow is a price-weighted index of 30 U.S. blue-chip companies, while AI-linked shares had mixed results. Nvidia and Taiwan Semiconductor Manufacturing Co.’s U.S.-traded shares each fell 1.8%. CoreWeave recovered from an early decline to finish higher, following a 15.5% drop in the previous session.
For final demand, the September Producer Price Index (PPI) rose 1.3% from August after seasonal adjustment. Its unadjusted increase over 12 months was 6.3%. The monthly rise was the largest since March 2022; the annual increase was the biggest since December 2022.
Energy was responsible for more than four-fifths of September’s increase in final-demand goods prices. The final-demand energy index climbed 10.8%, and gasoline prices rose 20.3%. The September Consumer Price Index (CPI), which measures prices from the purchaser’s perspective, increased 0.6% from August and 3.7% over the year. PPI tracks prices received by producers.
Company results also featured in the session. Marsh’s third-quarter revenue grew 8%, including 5% underlying growth. Adjusted earnings reached $2.03 per share, 10% higher than a year earlier. Bank of New York Mellon reported quarterly earnings of $2.34 per share; their shares rose 4.6% and 3.2%, respectively.
