Tech stocks 'on sale' as software sector drops 12% amid Iran ceasefire

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 upgraded to Buy with $200 target on path to Rule of 60 profitability

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.

Palo Alto Networks maintains buy rating despite target cut to $210 on cybersecurity demand

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.
