For months, I was the loudest voice of caution in the room. You’ve heard the arguments because I was the one making them, both in print and to any friend who would listen. “It’s a bubble,” I’d say, pointing to the stock chart that seemed to defy gravity. “This is Cisco in 1999 all over again. A picks-and-shovels play for a gold rush that’s about to go bust.”

Every headline seemed to confirm my cynical, and I believed, sagacious, worldview. The Financial Times report felt like the ultimate validation: Nvidia executives cashing out over a billion dollars in stock. To me, the signal was unmistakable. The insiders, the ones who truly knew the company’s health, were quietly heading for the exits at the peak. I saw the reporting from Yahoo Finance and The Motley Fool, relentlessly pushing the Cisco comparison and highlighting that billionaire investors like Philippe Laffont were selling their stakes. It all fit together into a neat, terrifying narrative: the ‘smart money’ was out, the insiders were cashing in, and the generative AI hype-train was about to go off the rails. I wasn't just reporting on this narrative; I believed it. I saw a house of cards, and I felt it was my duty to warn people before it collapsed.

I was so convinced, in fact, that I began outlining what I intended to be my magnum opus on the topic—a definitive piece laying out, point by point, why the Nvidia phenomenon was unsustainable. This, I thought, would be the article that people would point to after the crash and say, “He saw it coming.” The catalyst for my change of heart wasn't a sudden epiphany or a single conversation. It was something far more humbling: the slow, uncomfortable realization that the facts I was gathering for my takedown piece were actively dismantling my own arguments.

My entire thesis rested on the historical parallel to Cisco Systems. It was an elegant, compelling story. Cisco provided the essential plumbing for the dot-com boom, its valuation soaring on the promise of a new internet age. When the speculative dot-com companies went bust, Cisco’s orders dried up, and its stock cratered, wiping out fortunes. I was sure Nvidia was playing the same role for the AI boom.

But as I dug into the numbers for my article, intending to show the damning similarities, I found jarring differences instead. Cisco, at its peak in March 2000, was trading at a price-to-earnings (P/E) ratio of over 150. It was a valuation built almost entirely on future promises and speculation. When I looked at Nvidia, even at its staggering valuation, the P/E ratio was a fraction of that. Why? Because unlike the dot-com era, Nvidia’s rise is being fueled by astronomical, very real, and very present profits. We’re talking about a company with net income that has grown by over 700% year-over-year. Cisco was selling routers to companies with no revenue models; Nvidia is selling AI supercomputers to the largest and most profitable tech, healthcare, automotive, and scientific research institutions in the world. My core analogy, the very foundation of my skepticism, was built on sand. It was a comparison of sentiment, not substance.

With my primary pillar weakened, I doubled down on the insider selling. “Okay,” I thought, “forget the fundamentals. The executives are selling. That’s the ultimate tell.” The billion-dollar headline figure was my smoking gun. But here, too, the deeper I looked, the more the narrative unraveled. I pulled the actual SEC filings, and the context I found was absent from the sensational headlines. A significant portion of these sales were conducted under pre-scheduled Rule 10b5-1 trading plans. These are plans set up by executives months in advance, specifically to sell shares at a predetermined time or price. They are a tool for orderly liquidation and diversification, designed to avoid any suspicion of trading on non-public information.

Furthermore, the billion-dollar figure, while enormous, was misleading without knowing what percentage of their holdings it represented. In almost every case, the executives were selling a relatively small fraction of their total ownership. They weren't ‘dumping all their stock’; they were cashing in a small piece of their life-changing wealth while still retaining personal fortunes tied directly to Nvidia’s future success. This wasn’t a vote of no confidence. It was prudent financial planning. It was paying the enormous tax bills that come with vested stock options. It was funding philanthropic ventures. The story wasn’t “Rats Fleeing a Sinking Ship.” It was “Successful People Diversifying Their Assets.” One narrative sells clicks; the other is just boringly sensible.

Finally, I confronted the idea of the ‘smart money’ leaving, epitomized by Laffont’s Coatue Management selling shares. This had felt like the final confirmation. But a single manager’s decision is not a market-wide verdict. A fund manager’s job is to deliver returns for their clients, which often means taking profits after a monumental run and rebalancing a portfolio. It’s risk management. While I was fixated on who was selling, I was willfully ignoring who was buying, and more importantly, what the company itself was doing. I saw Nvidia making strategic acquisitions like CentML, not to cash out, but to deepen its moat in AI software optimization—a long-term move. I looked at the roadmap for the next-generation Blackwell platform and the reports that demand is still so high that it will outstrip supply for the foreseeable future. The narrative of ‘slowing growth’ was a gross mischaracterization. Shifting from once-in-a-generation hyper-growth to merely dominant, industry-leading growth isn’t a sign of failure; it's a sign of maturation into a foundational pillar of the global economy.

I’m not here to tell you that Nvidia is without risk or that its stock will only go up. That would be just as foolish as my previous certainty. But I am here to issue a retraction of my own conviction. My journey to write a story about a bubble forced me to see the substance beneath it. I was wrong because I was seduced by a simple, historical narrative that fit my bias. I was wrong because I focused on headline-grabbing numbers without seeking their context. I was wrong because I mistook profit-taking for panic and prudence for a lack of faith.

The real story of Nvidia isn't about history repeating itself. It’s about a new chapter being written—one driven not by speculative websites, but by one of the most profound technological shifts since the internet itself. And I, for one, have learned the hard way that it pays to read beyond the first page.
