Just noticed something interesting about Nvidia's valuation that most people are probably sleeping on. The stock hasn't been this cheap in almost a year, and when you actually dig into the numbers, the setup looks pretty compelling from a historical perspective.

Here's the thing that caught my attention: since early August last year, Nvidia has only gained about 5% while the S&P 500 climbed around 10%. On the surface that sounds weak, but the company has been absolutely crushing earnings the entire time. That disconnect is exactly what creates opportunities.

When you look at what a good PE ratio for a stock should be, context matters a lot. Nvidia is trading at roughly 37 times trailing earnings right now, which sounds expensive until you actually compare it to other mega-cap names. Costco is at 54x, Walmart is basically the same at 37.2x, and Apple and Amazon are sitting at 33x and 31x respectively. None of those companies are growing anywhere close to Nvidia's pace, and none have the AI tailwinds that Nvidia is riding.

Plus, that trailing PE is artificially inflated because of a one-time inventory write-down from last year. So the valuation narrative everyone's pushing doesn't really hold up.

But here's where it gets really interesting. From a forward earnings perspective, Nvidia looks almost absurdly cheap. At 22.1x forward earnings, it's basically trading at the same multiple as the overall market (21.9x for the S&P 500). Meanwhile the company just grew revenue 73% year-over-year and is expected to hit 77% growth next quarter. That's not the growth profile of a company that should trade at market-average multiples.

If you look at what a good PE ratio for a stock typically is during its growth phase, Nvidia probably deserves to be trading significantly higher. The AI buildout is expected to run through at least 2030, so this isn't some flash in the pan narrative.

Historically, when Nvidia has gotten beaten down like this, it doesn't stay down for long. I'd be watching this pretty closely because if the market reprices this back to more normal levels sometime in 2026, the returns could be pretty substantial. Sometimes the best opportunities come when everyone's distracted looking elsewhere.
