The Cboe (CBOE:CBOE) Volatility Index, or VIX, closed at 19.42 on Friday, October 30, 2026, up about 2.22 points from Thursday's 17.20, according to market data. The index, which reflects the volatility traders expect in the S&P 500 over the next 30 days based on Options prices, tends to rise when stocks fall and Demand for protection grows.

Friday gave it plenty of reason to climb. The S&P 500 fell 140.32 points to 7,580.07, the Nasdaq Composite tumbled 747.73 points to 25,437.00 and the Dow dropped 572.25 points to 51,770.31. For Wall Street as a whole, it was the worst day since June, and the Russell 2000 slipped 47.37 points to 2,811.84 as the selling reached smaller companies too.

Chips crater

The heart of the selloff was the semiconductor sector. Intel (NASDAQ:INTC) plunged to $65.76 after warning on Thursday night of cash burn this year and issuing a fourth-quarter outlook that fell short. The company cited a weak PC market tied to higher memory prices, Manufacturing bottlenecks and a factory accident in Israel. Market reports called it the biggest one-day drop on record for the stock, while other reports called it the worst day since 1974.

The Philadelphia Semiconductor index sank to 10,688.80 as Advanced Micro Devices (NASDAQ:AMD), Qualcomm (NASDAQ:QCOM), Marvell (NASDAQ:MRVL), Dell (NYSE:DELL) and Sandisk (NASDAQ:SNDK) tumbled and Nvidia (NASDAQ:NVDA), Broadcom (NASDAQ:AVGO) and Micron (NASDAQ:MU) fell sharply. One analyst called Intel's guidance "a perfect storm."

Intraday swings

The VIX was higher still during the session. It hit an intraday high of 23.93, according to market data, and stood at 22.75 at 3:04 p.m., according to market data, before easing into the close. Reports also differed slightly on the final reading, with market data putting it at 19.58 and market data describing it as just below 20.

The S&P 500 touched an intraday low of 7,527.67, according to market data, before recovering part of its loss in the afternoon.

Other sources of stress

Chips were not the only worry. Amazon (NASDAQ:AMZN) reported trailing 12-month free Cash Flow of negative $42.4 billion, Alphabet (NASDAQ:GOOGL) extended Thursday's record selloff, and crypto stocks fell after Binance was reportedly hacked for about $6.3 billion, a theft TRM Labs and Elliptic tied to North Korea. U.S. crude rose to $104.12 a barrel amid tensions around Iran and reported tanker incidents in the Strait of Hormuz.

The rate outlook added another layer. Traders see a December Fed hike as the likely outcome, according to CME FedWatch data cited by market data, and three Fed officials argued on Friday that rates need to go higher, according to market data. Credit markets also showed strain, as high-yield and investment-grade spreads widened, according to ICE BofA data cited by market data.

What to watch

Even after Friday's jump, the VIX closed below 20, a round number often cited as a dividing line between calm and nervous markets. Its October ride left investors with plenty to weigh as November begins.

Next week brings several potential volatility triggers: Apple (NASDAQ:AAPL)'s results on Monday, November 2, the midterm elections on Tuesday, November 3, ISM manufacturing and services data, and the October jobs report on Friday, November 6. "Global markets are ending an exceptionally busy week on a cautious note," a senior market analyst said. A senior market strategist, for his part, said the tech decline "does not appear abnormal" compared with earlier bull-market pullbacks.
