Shares of Palo Alto Networks (NASDAQ:PANW) climbed about 2% in premarket trading on Monday after Chief Executive Officer Nikesh Arora disclosed that he had purchased $10 million of company shares on the open market.
The disclosure, released after the close of trading on Friday, came during a broader decline in cybersecurity stocks. Palo Alto’s shares had dropped roughly 6% on Friday, while the wider sector — tracked by the HACK ETF — fell about 4%, compared with an approximately 2% decline in the S&P 500.
The selloff followed a Fortune report that artificial intelligence startup Anthropic was testing a new model called Mythos with advanced cybersecurity features. According to the report, details about the system were leaked due to weak controls within Anthropic’s content management system.
Arora’s transaction represents “the largest open market purchase we have seen from our coverage management teams, which reads bullish, particularly amidst market worries that AI vendors like Anthropic are focusing more on security,” said Barclays analyst Saket Kalia.
Barclays noted that one concern raised earlier this year was the limited amount of personal share buying by software executives, which some investors interpret as a lack of confidence in long-term valuations. Those concerns have intensified amid broader uncertainty over how artificial intelligence could reshape the software industry.
Unlike share buyback programs, an open-market purchase involves executives investing their own funds directly into company stock. “While many teams have announced repurchase authorizations, which are of course bullish, a personal purchase on the open-market arguably “puts their money where their mouth is”,” Kalia said.
Regarding the potential competitive threat from Anthropic, Kalia expressed doubt that the AI company would gain significant traction in cybersecurity. Horizontal technology firms “have historically had mixed success in cybersecurity,” he wrote, adding that Arora’s purchase likely reflects a similar assessment.
