The S&P 500 market update reveals a rough close to the week, with the S&P 500 tumbling 2.0% on Friday, March 28, as the Federal Reserve’s preferred inflation measure signaled persistent price pressures.

Key Stock Market Highlights from the S&P 500 Market Update
Lululemon (LULU) Stock Crashes 14.2% After Weak Outlook

Lululemon Athletica, a leading activewear brand, saw its stock plummet 14.2%—the biggest decline among S&P 500 stocks. While the company exceeded revenue and earnings expectations for its fiscal fourth quarter, its guidance for the current quarter and full year fell short. Executives attributed the lackluster outlook to declining foot traffic as budget-conscious consumers curb discretionary spending.
JPMorgan analysts lowered their price target on LULU, citing additional headwinds from tariffs and currency exchange fluctuations that could squeeze profit margins. The downturn raises concerns for the broader athleisure market, as brands navigate shifting consumer behaviors in an inflationary economy.
