U.S. stocks fell sharply in the past week after hopes for a pronounced cooling in inflation were dashed by a hotter-than-expected August inflation reading.

The Dow Jones Industrial Average logged a 4.1% weekly fall, while the S&P 500 dropped 4.8% and the Nasdaq Composite suffered a 5.5% decline. The S&P 500 ended Friday below the 3,900 level viewed as an important area of technical support, with some chart watchers eyeing the potential for a test of the large-cap benchmark’s 2022 low at 3,666.77 set on June 16.
