↓ -6%Wall Street strategists are viewing recent tech stock volatility as a buying opportunity following a two-week Iran ceasefire. The iShares Expanded Tech-Software Sector ETF has fallen 12% over the past month, despite the S&P 500 rising slightly. Ben Emons of FedWatch noted "a bit of an overreaction", whilst Mark Gibbens of Gibbens Capital said it's "time to jump in". Strategists highlighted opportunities in Palantir Technologies, Palo Alto Networks, and Oracle, despite recent share price declines. Nvidia has dropped from recent highs to trade at 21 times forward earnings. Tiffany McGhee of Pivotal Advisors praised Oracle's cash flow and enterprise contracts, whilst Gradient Investments' Keith Gangl called Palo Alto a rare opportunity to buy quality "on sale". Strategists cautioned that volatility remains, but emphasised AI as a powerful catalyst.
Palo Alto Networks has received a Buy initiation from Benchmark with a $200 price target, based on the company's trajectory towards achieving Rule of 60 profitability status in FY2026 through 22–23% revenue growth and 37% adjusted free cash flow margin. The cybersecurity firm reported Q2 FY2026 revenue of $2.594 billion, beating estimates, with non-GAAP EPS of $1.03 surpassing the 93 cent estimate. Next-Generation Security ARR reached $6.30 billion, up 33% year-over-year. Despite the stock trading down 10.33% year-to-date and below its 200-day moving average, 44 analysts rate it Buy or Strong Buy with a consensus target of $206.97. However, investors should consider the elevated 42x forward P/E valuation and integration risks from pending acquisitions.
Morgan Stanley identified five top cybersecurity stocks after attending the RSA Conference 2026: Microsoft, Palo Alto Networks, CrowdStrike, SailPoint and SentinelOne. The firm believes these companies are well-positioned to benefit from growing AI security demand as businesses deploy AI agents. Microsoft has 1.6 million security customers and a $20 billion revenue run rate, with analyst Keith Weiss setting a $650 price target, implying 80% upside. Analyst Meta Marshall gave Palo Alto Networks a $223 target (50% upside), noting its broad AI portfolio and advantageous position despite a 20% year-to-date decline. CrowdStrike received a $510 target (38% upside) and was upgraded to a top pick based on its strong endpoint franchise and AI-driven security capabilities.
Palo Alto Networks shares rose 5% on Monday to close at $154.35 following news that CEO Nikesh Arora purchased an additional stake worth $10 million in the company. According to a regulatory filing, Arora acquired 68,085 shares on 27 March at prices ranging from $146.87 to $147.48. The cybersecurity firm also unveiled Prisma AIRS 3.0, a new security platform designed to protect the entire agentic AI lifecycle. The product addresses security challenges in AI-powered enterprises by discovering AI agents across cloud environments, assessing risks continuously and providing real-time protection at scale. Palo Alto Networks said the platform enables enterprises to move beyond simply monitoring AI interactions to safely authorising autonomous execution, closing visibility gaps in AI operations.
Palo Alto Networks has received a buy rating from Freedom Capital Markets, which reduced its price target from $230 to $210 whilst maintaining its recommendation. The cybersecurity firm reported strong second-quarter fiscal 2026 results, with earnings of $1.03 per share beating estimates of $0.94, and revenue of $2.6 billion exceeding expectations of $2.58 billion. Freedom Capital attributed the performance to growing demand for cybersecurity platform integration and successful acquisitions of CyberArk and Chronosphere. The company's third-quarter forecast also surpassed expectations, driven by merger and acquisition activity. The analyst raised revenue forecasts but lowered diluted non-GAAP earnings per share estimates, citing the transitional period of merger integration. Palo Alto Networks provides cybersecurity solutions including firewalls, malware protection and cloud security.
