The author highlights three lesser-known AI stocks worth watching: CoreWeave (AI infrastructure/data centers), TTM Technologies (circuit boards for data centers), and Fastly (content delivery and cybersecurity). All three show strong revenue growth, but only TTM is currently profitable. CoreWeave faces high debt and operational costs despite impressive sales growth, while Fastly is reducing losses. The author is monitoring these stocks for potential price dips before investing.

AI Insight
Record revenue of $624M in 2025 with positive growth trajectory, but company remains unprofitable with $121.7M net loss. Improving losses and positioning for AI agent traffic are positive, but customer concentration risk (33% from top 10 clients) is a concern.
Fastly CEO Kip Compton sold 49,350 shares worth $1.2 million on March 11, 2026, as part of a pre-established Rule 10b5-1 trading plan adopted in August 2025. The sale is not concerning as Compton retained over 1 million shares. While the stock has surged 265.5% over the past year driven by AI-related traffic increases, its price-to-sales ratio of 6 is at a multi-year high, making it expensive. The analyst recommends waiting for a price drop before buying.
The Motley Fool•Robert Izquierdo
AI Insight
The company shows strong fundamentals with record revenue of $624 million (up 14.8% YoY) and exceptional stock performance (+265.5% in one year), driven by AI traffic. However, the stock is trading at an expensive valuation (P/S ratio of 6 at multi-year highs), and the CEO's insider sale, while explained by a pre-planned trading arrangement, suggests caution. The analyst recommends waiting for a pullback rather than buying at current levels.
The Supreme Court ruled 6-3 that President Trump's sweeping global tariffs were unconstitutional, finding that the International Emergency Economic Powers Act does not authorize the president to impose tariffs without clear congressional authorization. The decision triggered a sharp rally across U.S. equities, with 10 stocks posting significant gains following the ruling that invalidates tariffs that had reached up to 145% on some products.

The Motley Fool•Eric Trie
AI Insight

Fastly stock surged 72% after reporting Q4 revenue of $172.6 million (23% YoY growth) and adjusted EPS of $0.12, double Wall Street expectations.

Management projects 14% revenue growth to $710 million in 2026, with AI expected to be a continued tailwind.
The Motley Fool•Joe Tenebruso

U.S. stock futures rose on Thursday following a strong January jobs report showing 130,000 jobs added, exceeding expectations.

Benzinga•Erica Kollmann
AI Insight
Fastly significantly beat earnings expectations on both EPS and revenue, reported record quarterly metrics including gross margin and operating profit, issued forward guidance well above analyst estimates, demonstrated strong customer retention (110% LTM NRR), and achieved 55% growth in remaining performance obligations. The 26% stock price surge reflects strong market confidence in the company's transformation and growth trajectory.
Anthropic's launch of Claude Cowork, an AI tool designed to replace multiple software tools, triggered a significant sell-off in SaaS stocks. Software companies like Shopify, Monday.com, and Fastly dropped 15-23%, similar to the market's reaction to DeepSeek last year. However, analysts suggest the impact varies by company type—mission-critical, deeply integrated software providers are better positioned to weather AI disruption than single-function tools. Meanwhile, January job data showed the lowest openings since 2020 and highest layoffs since 2009, though unemployment remains historically average.
