U.S. stocks plunged on Wednesday, extending the week’s declines as investors responded to news that the consumer-price index spiked higher in April.

The index rose 4.2% over the past 12 months, while the so-called core CPI recorded a gain of 3%.

The

Dow Jones Industrial Average

 dropped 682 points, or 2% — its largest percentage point drop since January. The 

S&P 500

 fell 2.1%, and the 

Nasdaq Composite

 declined 2.7% and is down more than 5% over the last three trading days. The 10-year Treasury yield rose to 1.695%.

Analysts and economists say part of the reason for the large year-over-year increase is the so-called base effect, which describes how a very low inflation reading in the year prior can lead to a relatively high reading in the following year if prices normalize. April 2020 saw a CPI of 0.8% amid a significant crash in the price of oil, when crude prices turned negative for the first time.

“Consumer price inflation in every economy is telling us about the oil price a year ago,” said
Paul Donovan,
the chief economist at UBS Global Wealth Management. “This is not a concern, but markets want to worry about something.”

Rising prices can weigh on corporate profit margins if companies are unable to pass the costs on to consumers. They also can impact stock valuations, which tend to be lower when inflation is high. Tech stocks, in particular, are vulnerable because of their high valuations and the amount of growth expected in the future.

The main U.S. stock indexes were weaker on Tuesday as well, as investors worried about the outlook for inflation and monetary policy.

“A number of reasons have been given for yesterday’s broad-based weakness, the main being concern that the recent sustained rise in commodities prices could prompt a sharper permanent state of rising inflation in the weeks and months ahead,” said Michael Hewson, an analyst at CMC Markets.
