Nasdaq-100 slide, oil price climb, and Eli Lilly's weight-loss pill

Fed Chair Warsh has not ruled out an October rate increase, and card balances could feel it.

At Friday’s close: S&P 500 −1.09%, Nasdaq-100 −2.50%, Dow −0.34%

Nasdaq-100 slides as AI debt worries hit chip and cloud stocks

Nasdaq stock market and AI chip makers, the subject of the lead story

The Nasdaq-100 slid 2.5% on Friday as worries over the debt loads of AI infrastructure companies hit memory chip and cloud computing stocks. CoreWeave Inc. (CRWV) tumbled 11.9%. Memory makers Micron Technology Inc. (MU) and SanDisk (SNDK) fell 5.6% and 6.8%. The S&P 500 slid 1.1%, and the Dow fell 0.3%.

Reports said the cost of insuring CoreWeave's debt against default hit a record this week. Money rotated into defensive names, the steadier businesses people use in any economy. Utilities funds rose 1.3% and consumer staples funds gained 1.1%. Separately, Federal Reserve Chair Warsh declined to rule out an October interest rate increase after higher-than-expected readings on consumer and producer prices.

For readers

What it means for you: People carrying a credit card balance or a home equity line are most exposed to Fed Chair Warsh's refusal to rule out an October rate increase. Most such rates are tied to the prime rate, which moves when the Fed changes its benchmark. The Fed's two-day meeting begins Tuesday, Oct. 27.

If you own

  • Tech funds that track the Nasdaq-100 slid 2.5% on Friday, leaving the index at 29,187.55. A daily move that size could show up quickly in a tech-heavy fund's value, since such funds lean on fewer industries than a broad market fund.

  • Small-company funds lost ground on Friday, with the widely held small-company fund IWM sliding 1.7%. Smaller companies often swing more than large ones, and holders may see bigger day-to-day changes in value.

  • Technology sector funds fell 3.0% on Friday, a large daily move for the sector. Holders of a fund focused on a single industry could see sharper swings than those in a broad index fund.

  • Energy funds and fuel costs may both feel the latest move in oil. A fund that tracks crude oil futures, USO, jumped 2.8%, and a lasting rise could feed through to prices at the pump.

Three changes that matter

How it works

Sectors and the market

One group can buck the index. The S&P 500 tracks large U.S. companies and gives the biggest ones the most weight. A sector, meaning a group of companies in one industry, can rise while the index falls when that group is a small slice of the total. On Friday, crude oil prices rose and energy shares gained, yet the broad market fell. In all, 819 stocks declined. The split often shows up when oil prices move sharply on supply news.

The close

The big picture. Last week was hard on technology. Worries about the debt behind AI spending left the Nasdaq-100 down 5.5% for the week, and falling stocks outnumbered rising ones on Friday. Even so, the S&P 500 has edged up 0.1% for October, helped by gains in energy, consumer staples and utilities. Different parts of a broad portfolio rarely fall together, and that spread softened the week's losses.

On the calendar. The final October University of Michigan survey comes out on Friday, Oct. 23, at 10:00 a.m. ET. It shows households' inflation expectations, which could matter to a Fed weighing higher rates. Early trade and inventory figures on Wednesday, Oct. 28 feed into the estimate of economic growth.
