A $1,000 investment in Fortinet (FTNT) made 10 years ago in August 2016 would be worth $24,198.88 as of August 28, 2026, representing a 2,319.89% gain. This significantly outperformed the S&P 500's 256.42% return over the same period. Fortinet, a cybersecurity leader, reported 2025 revenues of $6.8 billion (up 14% YoY) and raised its 2026 guidance to $8.02-$8.18 billion. The company faces competition from Palo Alto Networks, CyberArk, Qualys, and Cisco.

Both CrowdStrike and Okta exceeded Q2 expectations and raised guidance, with CRWD surging 20% and OKTA soaring 30%. However, CrowdStrike's valuation has become stretched at 150X forward earnings compared to Okta's 76X. While CrowdStrike showed stronger growth, Okta offers better value with improving margins, robust cash flow, and a more reasonable valuation, earning a Zacks Rank #2 (Buy) versus CRWD's Rank #3 (Hold).

Palo Alto Networks stock surged 11.1% on reports the cybersecurity company is shifting into acquisition mode. After failed attempts to acquire Okta and Datadog at lower valuations, Palo Alto is now targeting smaller companies Cribl and ClickHouse for potential acquisition.

Wall Street analysts expect Palo Alto Networks to report Q4 earnings of $0.98 per share (up 3.2% YoY) with revenues of $3.35 billion (up 32.1% YoY). Key metrics show strong subscription revenue growth of 45.6% YoY and RPO reaching $20.96 billion. The stock has outperformed the S&P 500 with +8% returns over the past month and holds a Zacks Rank #2 (Buy) rating.

SentinelOne's stock has risen 42% this year on the strength of its AI-native cybersecurity platform, but the article advises against buying before its August 27 earnings report. While the company offers competitive advantages through its Singularity platform and trades at a lower valuation than peers, it faces intense competition from larger players, has consistently missed revenue estimates, and remains unprofitable with no clear path to profitability.

With the S&P 500 trading at historically high valuations (CAPE ratio of 41.9) amid geopolitical tensions and elevated inflation, growth stocks with lofty valuations are vulnerable to sharp corrections. AMD and CrowdStrike are identified as two popular tech stocks trading at premium valuations that could be worth selling if a market downturn occurs.

Despite CrowdStrike's strong business performance with record cash flows and 24% ARR growth, the author is avoiding buying more shares due to its expensive valuation of 44 times sales. While the company remains a long-term hold, the author believes better entry points will emerge and is deploying capital to more fairly valued stocks.

Palo Alto Networks' market value nearly tripled in a year from $113 billion to $295 billion, but the underlying business growth doesn't justify the valuation increase. While the company showed solid Q3 results with 31% revenue growth and strong next-generation security ARR growth of 60%, much of this came from acquisitions. The stock now trades at 96x forward earnings, pricing in years of excellent execution with limited margin of safety.

Investors are rotating money from semiconductor stocks into software stocks in 2026. While chip stocks like Intel have surged over 170% year-to-date, they've become expensive. Meanwhile, software-as-a-service stocks were heavily sold earlier in the year due to AI disruption fears, making them attractive valuations. However, the article advises against abandoning chip stocks entirely, as they continue strong earnings growth and some like Nvidia maintain reasonable valuations.

The iShares Expanded Tech-Software ETF (IGV) has declined 11% this year amid AI disruption concerns, but recent momentum loss in the AI infrastructure boom could present a buying opportunity.

Palo Alto Networks stock fell 4.9% on Wednesday despite Evercore ISI analyst Peter Levine raising his price target from $320 to $415, citing strong positioning in cybersecurity and expected free cash flow growth. However, Levine's $6.5 billion FCF forecast for 2027 significantly exceeds Wall Street consensus of $5.2 billion, raising questions about valuation at 52x projected FCF if growth targets aren't met.
