A cybersecurity re-rating is sweeping through the group Thursday, with the money flowing hardest into the names the market had written off. First Trust NASDAQ Cybersecurity ETF (NASDAQ:CIBR) is up 7% to $99.83. At the same time, Invesco QQQ Trust (NASDAQ:QQQ) is up 0.9% to $718.35, and that gap identifies the day as a sector event rather than a market event.
Zscaler (NASDAQ:ZS) stock is up 10% to $187.83 and leads the group. Zscaler shares were down 24% year to date through Wednesday’s close, making it the only featured name still negative on the year. SentinelOne (NYSE:S) stock is up 10% to $22.62, and SentinelOne shares were up 37% year to date through Wednesday’s close.
Meanwhile, Datadog (NASDAQ:DDOG) stock is up 6% to $241.53 as the observability name rides the software wave alongside the security cohort. Datadog shares were up 67% year to date through Wednesday’s close. Fortinet (NASDAQ:FTNT) stock is up 8% to $169.49, and Fortinet shares were up 98% year to date through Wednesday’s close, the smallest gainer today despite the broadest sector tailwind.
Read-Across From Wednesday’s Reports
No company-specific news has been verified at Zscaler, SentinelOne, Datadog or Fortinet today. The catalyst is read-across from CrowdStrike Holdings (NASDAQ:CRWD) and Okta (NASDAQ:OKTA), both of which reported after Wednesday’s close and reset expectations for security software spending across the group. Readers can find the earnings detail in our coverage of the twin reports.
The order of returns tells the story. Zscaler is the only featured laggard on the year and it’s leading the group today, while Fortinet has nearly doubled year to date and is gaining least. That pattern is what sentiment repair looks like, with capital rotating into the skepticism trades rather than piling further into the extended winners.
Datadog Is the Odd Name Out
Datadog operates in observability and monitoring rather than cybersecurity, so a security-spending read-across reaches it only indirectly, through the shared enterprise software budget that funds both categories. The move in Datadog stock says more about broad software sentiment than about any specific security demand signal from Wednesday’s reports.
