Fortinet (NASDAQ:FTNT) fell steeply on Thursday, October 29, 2026, one of several high-profile technology names to suffer heavy losses that day. The drop kept Cybersecurity stocks in focus as trading opened on Friday, October 30, 2026. Available reports did not detail Fortinet's move on Friday.

Fortinet, based in Sunnyvale, California, sells firewalls and other network security products and software. Thursday's selloff in the stock came on the same day ServiceNow (NYSE:NOW) suffered its worst day on record and Alphabet (NASDAQ:GOOGL) had its worst day ever.

Cybersecurity sells off on Friday

On Friday, cybersecurity stocks broadly declined as part of a wider technology rout. A cybersecurity-focused exchange-traded fund fell sharply, and individual security names moved lower with the sector. Okta (NASDAQ:OKTA) and Cloudflare (NYSE:NET) both fell sharply with no company-specific news, moving with software and internet stocks across a session in which few technology names escaped the selling.

The selling reflected a session in which investors dumped almost anything tied to tech and AI. Intel (NASDAQ:INTC)'s weak fourth-quarter outlook and warning of cash burn this year sparked a rout in chip stocks, with Intel suffering what market reports called its steepest one-day drop on record. Amazon (NASDAQ:AMZN) reported trailing 12-month free Cash Flow of negative $42.4 billion and signaled another increase in Capital spending next year.

A notable backdrop: the Binance hack

Friday also brought a vivid reminder of cyber risk. Binance, the world's largest crypto exchange, was reportedly hacked for about $6.3 billion, which would make it the largest crypto heist on record. Blockchain analytics firms TRM Labs and Elliptic tied the attack to North Korea, according to market data, and Binance blamed a compromised laptop belonging to a DevOps engineer, market reports said.

The hack hit crypto stocks hard, but it did not lift cybersecurity names, which were swept up in the broader tech selling instead.

The wider market

The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average dropped 572.25 points to 51,770.31 and the Nasdaq Composite lost 747.73 points to 25,437.00, its worst day since June. The Russell 2000 slid 47.37 points to 2,811.84.

Technology was the worst-performing sector, while six of 11 sectors rose, led by energy, consumer staples, utilities and health care. Oil above $100 a barrel and expectations of a December rate increase from the Federal Reserve added to the defensive tone. The number of stocks hitting 52-week lows jumped to 448 from 230 on Thursday.

Strategists said investors are becoming pickier. "The love-hate relationship with tech and AI continues, and investors are becoming more discerning following earnings," a senior market strategist said on Thursday. An Investment strategist said: "The Earnings bar is very high."

The strategist also said, that the tech decline "does not appear abnormal" compared with earlier bull-market pullbacks.

What to watch

Cybersecurity investors will be watching whether the sector stabilizes once the broader tech selling eases. Palantir (NASDAQ:PLTR) and Apple (NASDAQ:AAPL) report on Monday, November 2, and Datadog (NASDAQ:DDOG) reports during the week, offering more reads on software demand.

The midterm elections on November 3 and the October jobs report on Friday, November 6, will shape the macro backdrop. For Fortinet, the question is whether Thursday's drop marks a reset or the start of a longer reassessment of security software valuations.
