Been watching Cloudflare (NET) pretty closely lately, and there's definitely something worth paying attention to here. The stock had an incredible 2025 run, up 83%, but then took a sharp hit in late February - dropped 16% in just a few days. That kind of move always makes you wonder what's actually going on.

Let me break down what I'm seeing. Cloudflare is basically the invisible infrastructure that keeps websites and apps secure and fast. They claim to protect around 20% of all websites globally, which is pretty wild when you think about it. The business fundamentals actually look solid - they just closed their biggest deal ever in Q4, worth about $42.5 million in annual contract value. Revenue grew 30% through 2025. Customers include some heavy hitters like Shopify, SoFi, and DoorDash.

Here's where the warning symbol comes in though. That February pullback wasn't really about Cloudflare's business falling apart. It was more about the broader market getting nervous - profit-taking after a huge run, uncertainty around tariffs, and a general sell-off in software stocks as people worried about AI disrupting SaaS business models. The stock bounced back to around $190 after, so it wasn't a fundamental breakdown.

But here's the thing that caught my attention - and this is where I'd put up a warning signal - the company's net losses actually got worse. They went from losing $78.8 million in 2024 to $102.3 million in 2025. That's moving in the wrong direction, even while revenue is growing. The stock is also trading at something like a 154 forward P/E ratio, which means you're really paying for future growth expectations.

The CEO Matthew Prince is making a big bet on AI agents becoming a critical part of their future. He mentioned that AI agent requests on their network more than doubled in January alone. And yeah, if you believe that AI security is going to become increasingly important, Cloudflare could be positioned well. But that's a big if, and it's priced in already.

I think this is one where you need to watch for warning signs carefully. If they execute on the AI vision, shares could get much more expensive. But if they don't hit those growth targets, the stock has room to fall hard given how stretched the valuation is. The February dip might have been a decent entry point for believers, but I'd be cautious about chasing it at these levels without seeing more evidence they can actually turn those losses into profits.
