Dec 12 (Reuters) – The S&P 500 and Nasdaq closed more than 1% lower on Friday as investors moved money out of technology and into other sectors as rising U.S. Treasury yields added pressure as Broadcom Inc. and Oracle stoked concerns about an AI bubble and some policymakers expressed opposition to monetary easing.

Treasury yields rose after a group of Fed officials who voted against the central bank's interest rate cuts this week expressed concerns that inflation was too high to justify lower borrowing costs.

Broadcom (AVGO.O)opens a new tab Shares fell 11.4% after the chipmaker warned of shrinking future profit margins, raising fresh concerns about the profitability of soaring AI investments.
Oracle (ORCL.N)opens a new tab It fell 4.5%, on top of a drop of about 11% on Thursday following the cloud software company's weak financial outlook. Oracle stock was under pressure on Friday even after the company denied a Bloomberg report that ChatGPT maker OpenAI's data centers were delayed.

It also didn't help that the S&P 500 and Dow Jones Industrial Average closed at new highs on Thursday, and that investors were focused on key labor market and inflation data to be released next week, said Anthony Saglimbene, chief market strategist at Ameriprise.

“It's not surprising to see the market sell off today after a pretty strong couple of weeks,” Saglimbene said, following the record close, adding, “There's some confusion on the AI ​​theme right now, so investors today are looking at some of the more defensive sectors.”

The Labor Department's report on nonfarm payrolls, consumer inflation and retail sales is expected to be released next week and could provide greater insight into the health of the economy after the October government shutdown left investors and policymakers hungry for official statistics.

“The market is probably a little cautious about heading into these big numbers next week,” the strategist said.
