Investors were struggling to find their footing after three benchmark indexes Tuesday saw their worst daily losses since June 2020 as August's disappointing inflation data likely implied another historically large interest-rate hike from the Federal Reserve. Earlier Wednesday, the August producer-price index, or PPI, which measures the cost of wholesale goods and services, dropped 0.1% in August, mostly due to lower gasoline prices. Core PPI, a separate measure of wholesale prices that excludes volatile food and energy costs, rose by 0.2% in August.
