1542 ET - Some cybersecurity stocks are trading at lofty valuations following a Monday rally fueled by a sell-off in the chip sector and fears of AI cyberattacks, with names like Palo Alto Networks and CrowdStrike valued above their peak multiples in 2021. "We're definitely in a premium valuation territory," Jefferies analyst Joseph Gallo says in an interview, adding that inflecting fundamentals could support upward estimate revisions. "It's very clear that people are looking for momentum and inflection and durability, and that will ultimately justify valuations." The rally likely raises the bar for the next season of cybersecurity earnings, Gallo adds.
