Dow drops 1,100 points for its biggest decline since 2020 as the sell-off this year on Wall Street intensifies. The Dow Jones Industrial Average posted its biggest loss since 2020 on Wednesday after another major retailer warned of rising cost pressures, confirming investors’ worst fears over rising inflation and rekindling the brutal 2022 sell-off. Markets returned to heavy selling after two back-to-back quarterly reports from Target and Walmart stoked investor fears of rising inflation taking a bite out of corporate profits and consumer demand. It’s the fifth Dow decline of more than 800 points this year, which all occurred as the stock sell-off intensified within the last one month. In an appearance Wednesday on CNBC’s “The Exchange,” Jeremy Grantham said the current downturn is worse than the tech bubble of 2000. The investor, known for identifying market bubbles, said stocks can more than double their losses.
