Key Highlights

● Broadcom fell Friday as selling spread from debt-laden AI names to established chip leaders.

● Reports cited the broad chip selloff rather than any Broadcom-specific announcement.

● TSMC posted third-quarter revenue of $46.72 billion, above guidance, as a bright spot.

● Meta reports Oct 21, with Texas Instruments and Lam Research; the Fed decides Oct 28.

Broadcom caught in the downdraft

Broadcom (NASDAQ:AVGO) fell on Friday, according to market reports, as the selling in chip stocks spread from smaller, debt-laden AI infrastructure companies to some of the industry's most established names. The reports cited the broad chip selloff rather than any Broadcom-specific announcement.

Broadcom designs networking chips that link servers together inside data centers, along with custom AI processors built for large cloud customers, and it also runs a sizable infrastructure software business. That makes the company a central supplier to the AI build-out, and it has traded as one of the sector's bellwethers.

Every chip stock in the red

The selling on Friday was sweeping. All 30 members of the PHLX Semiconductor Index fell, and the index closed at 11,137.29. Market data showed 57 of the 60 stocks in a broader semiconductor basket falling during the session. Advanced Micro Devices (NASDAQ:AMD) sank, Arm Holdings (NASDAQ:ARM) tumbled, Marvell Technology (NASDAQ:MRVL) fell and Micron Technology (NASDAQ:MU) slid.

Reports differed on how long the sector's losing streak had run. Some counted eight straight declines for semiconductor benchmarks, one described a ninth, and another called it the longest losing streak since 2008.

From what AI can do to how it is paid for

According to market commentary, investors have shifted from focusing on what artificial intelligence can do to asking how its infrastructure will be financed. Companies that rely on debt to build data centers were hit hardest, but concern about future spending also weighed on the suppliers that sell into those projects.

A published report said the rotation erased more than $1 trillion from semiconductor and AI-related stocks over the week. Goldman Sachs published a note describing hedge-fund selling of AI names as a "tactical rotation."

One market commentator said, "The AI group is now splitting between companies that can fund the buildout themselves and those that have to borrow," and "That is a change in character, and it's another reason the leaders no longer look like a safe haven."

The index picture

The Nasdaq-100, where Broadcom ranks among the largest members, fell sharply on Friday, though reports differed on the size of the decline. The Nasdaq Composite tumbled 572.99 points to 26,140.03, capping its worst week since June. The S&P 500 slid 84.62 points to 7,659.44, and the Dow Jones Industrial Average slipped 175.28 points to 52,002.41, cushioned by gains in energy and financials.

The Cboe Volatility Index climbed 3.53 points to 19.99, touching 22.31 intraday, its highest since June 11.

A bright spot for the industry

Not all industry news was negative. TSMC (NYSE:TSM), the world's largest contract chipmaker, reported third-quarter revenue of $46.72 billion, above its guidance, and kept its 2026 capital spending plan at $60 billion to $64 billion. Nvidia (NASDAQ:NVDA) CEO Jensen Huang said AI chip orders keep growing.

Broadcom Awaits Meta Spending Cues

The Federal Reserve's next rate decision lands October 28. The next big test for AI chip suppliers arrives with Big Tech earnings. Texas Instruments (NASDAQ:TXN) and Lam Research (NASDAQ:LRCX) also report on October 21. Meta Platforms (NASDAQ:META) reports the same day, and investors will look for updates on its data-center spending plans, which drive demand for networking and custom silicon.
