NVIDIA’s Valuation and the DeepSeek Disruption
Before this past weekend, we had already been analyzing NVIDIA’s (NVDA) valuation, applying the Mauboussin expectations framework to understand what growth was needed to justify its massive $3.6 trillion market cap. Is Nvidia Overvalued? What we found was eye-opening: NVIDIA’s stock price implied that the company would grow its free cash flow (FCF) at 10.6% annually—forever.
As luck would have it, a significant event shook the AI landscape as we worked through these numbers. Over the weekend, Chinese AI company DeepSeek announced that it had developed a more efficient AI model that cost only $6 million to build.
This news is significant because it represents a technological breakthrough and highlights a key challenge for NVIDIA: U.S. restrictions prevent it from selling its most advanced AI chips to China, forcing Chinese companies to develop their own solutions. The takeaway? China has found a workaround—and may have even built a better model in the process.
The market responded immediately. On Monday, the 27th, NVIDIA’s stock sank 18%, reducing its market cap by over $600 billion.
What Is the Mauboussin Framework?
To understand whether NVIDIA’s stock price made sense, we used the Mauboussin expectations framework from Michael Mauboussin’s book Expectations Investing: Reading Stock Prices for Better Returns, which explains how to reverse-engineer market expectations.” which explains how to reverse-engineer market expectations. Rather than guessing what a stock should be worth, this approach starts with its current price and works backward to determine the market’s assumed growth rate.
Here’s how we applied it to NVIDIA:
• We took Wall Street’s free cash flow (FCF) estimates for the next several years.
• Using those numbers, we backed into the growth rate needed to justify NVIDIA’s $3.6 trillion valuation.
• The result? A required long-term growth rate of 10.6% per year—in perpetuity.
Why This Is a Huge Assumption
A 10.6% perpetual growth rate is extremely rare, if not unrealistic. Here’s why:
• The global economy grows at around 3% per year on average. NVIDIA would have to outpace the entire world economy forever.
• Even the most successful companies struggle to sustain 5%+ growth; intense competition, market saturation, and economic cycles inevitably slow them down.
• A perpetual growth rate above 10% is almost unheard of in stock market history.
For NVIDIA to justify its $3.6 trillion valuation, it would need to:
• Dominate AI permanently, with little to no competition.
• Expand its market indefinitely, despite real-world limits on technology adoption.
• Maintain or improve its margins, even as industries mature and pricing pressure increases.
Tech stocks like Nvidia remind me of past market cycles where investors believed certain stocks could grow indefinitely. A similar pattern can be seen today in The Magnificent 7 Shaping Market Trends analysis, where a handful of companies dominate the market narrative.
Why the DeepSeek News Matters
Before the DeepSeek announcement, NVIDIA’s valuation was already under scrutiny. However, this new development directly challenges the assumption that NVIDIA will remain the dominant force in AI:
• Stronger-than-expected competition: DeepSeek’s model suggests that NVIDIA’s technology may not be as untouchable as investors assumed.
• China’s rapid innovation: U.S. export bans were expected to slow China’s AI progress. However, the emergence of DeepSeek suggests that they may have actually accelerated it.
• NVIDIA’s valuation left no margin for error: At $3.6 trillion, the stock was priced for near-perfect execution—but as Monday’s 18% drop showed, even the perception of a threat can send it tumbling.

What This Means for Investors
NVIDIA’s valuation assumed 50% free cash flow growth through 2027, then a sustained 10.6% annual growth rate in perpetuity. Even before the DeepSeek news, that seemed unrealistically high. Those expectations look even harder to meet with a serious new competitor emerging.
For investors, this raises key questions:
• How much of the AI boom is already priced into NVIDIA’s stock?
• Can NVIDIA maintain its dominance, or will competitors like DeepSeek force it to lower prices, cutting its margins?
• Does NVIDIA’s valuation still make sense after this news—or was it priced for perfection?

Conclusion
Before the DeepSeek news broke, we were skeptical of NVIDIA’s valuation. Now, that skepticism looks even more justified.
NVIDIA remains a leader in AI, but the DeepSeek announcement is a wake-up call—the competitive landscape is evolving faster than expected. The AI race is far from over, and NVIDIA’s ability to maintain its dominance is no longer a given. The 18% drop in one day reflects how vulnerable high-growth stocks can be when expectations are too aggressive. Yes, Mr. Market, valuations still matter.
