Shares of CoreWeave dropped 7%, continuing a downward trend after declining over 15% the previous day. The losses have been attributed to fears that CoreWeave is accruing too much debt to fund its AI expansion efforts. Analysts indicated concerns about rising corporate bond yields in this environment.

Alex Shahidi, co-CIO of MAI Capital Management, highlighted that as Treasury yields reach 5%, the highest since the early 2000s, investors may reconsider substantial investments in AI. He stated, "It's not are you in or out of AI; it's how concentrated you want to be."

In addition to CoreWeave, Micron Technology and SK Hynix have experienced declines tied to worries over a memory chip surplus, exacerbated by intensified competition from China. Tesla CEO Elon Musk mentioned on X that China will significantly increase its production of RAM by 2028.

Conversely, the market found support from gains outside the tech sector. Shares of Walmart increased by 4%, while Merck rose over 3%, and Nike shares jumped by more than 5%.

Investors also reacted to the latest inflation data. The producer price index for September recorded a 1.3% increase month-over-month and a 6.3% rise year-over-year, marking the largest gains since 2022. This data raises concerns that the Federal Reserve may tighten monetary policy more aggressively as inflation persists.

David Russell, global head of market strategy at TradeStation, noted, "Today's PPI report, after Wednesday's CPI, confirms inflation is getting worse as energy prices stay high."

In related news, Crocs shares surged 6% following an upgrade from Barclays, which lifted the stock's price target by 18% to $139, citing increased visibility in the company's growth potential.

Meanwhile, the Russell 2000, which tracks small-cap stocks, fell into correction territory with a decline of 11% from its August 14 record close, down 2.8% for the week.

As trading opened, the S&P 500 and Nasdaq Composite began in negative territory, while the Dow remained positive. Additionally, the producer price index results indicated elevated wholesale inflation, prompting further market reflections on future Federal Reserve actions.
