The week almost ended when oil prices fell and consumer confidence plummeted, with the University of Michigan reporting an all-time record low of 47.6. Despite this, the S&P 500 gained 3.9% on the week, marking its best weekly performance since May 2025. However, the price of oil fell 17% the next day, leading to a 12.2% drop on the following day. The government reported that consumer prices rose by 0.9%, largely due to a 21.2%, surge in gasoline, the largest single-month increase since federal records began in 1967. Year-ahead inflation expectations also jumped from 3.8% to 4.8%. However, software stocks had their worst week in years due to artificial intelligence's influence on legacy enterprise valuations.
