CrowdStrike and Palo Alto Networks hit record highs after an AI security conference. Traders rotated into pure-play vendors. Earnings are next.
CrowdStrike Holdings and Palo Alto Networks each closed at an all-time high Monday, the session after a major cybersecurity conference where speakers warned that generative AI is lowering the barrier for attackers. The conference, held in San Francisco, included presentations from former national security officials who described AI-augmented phishing and deepfake social engineering as already active.
Both stocks rose more than 3% on the session. CrowdStrike added $8.5 billion in market cap. Palo Alto Networks gained $6.2 billion.
Traders said the move reflected a rotation out of general tech names into pure-play security vendors. The relative strength of the cybersecurity sub-sector has been building for weeks. The ETF HACK is up 12% over the past month. The conference gave a specific catalyst: a keynote from a former NSA director who said AI tools are "finding the gaps in human judgment faster than we can patch."
Microsoft, which also has a growing security business, rose 0.8% and lagged its peers. The company's Alpha Score sits at 71 out of 100, a "Moderate" label reflecting its broader exposure to enterprise software and cloud competition. Palo Alto Networks scored 47. CrowdStrike scored 55. Both are labeled "Mixed." The event-driven buying ignored the scores.
"The market is pricing an assumption that legacy security budgets will shift to AI-aware platforms," said a portfolio manager at a Boston-based technology fund. "CrowdStrike and Palo Alto have the most direct messaging around AI threat detection."
The rally pushed CrowdStrike above $400 for the first time. Palo Alto Networks cleared $380. Volume was roughly double the 20-day average on both names. Options activity skewed heavily to calls. Open interest on November $400 strikes for CrowdStrike rose 40% in two days.
The next scheduled catalyst is the companies' quarterly earnings, due in late November. Neither has pre-announced. PE ratios for both now sit above 70x forward earnings, a level that has historically preceded corrections in the sector. For now, the AI security narrative is the only one that matters.
"You can't short a story that's making the front page of the conference," the fund manager said. "You wait for the first miss."
