Renowned finance professor Aswath Damodaran from New York University has issued a nuanced warning about the Magnificent Seven tech stocks, suggesting that while their AI-driven valuations may be reaching bubble territory, any market correction should be viewed as a buying opportunity. The Magnificent Seven—including Amazon, Meta, Tesla, and Nvidia—now account for approximately one-third of the S&P 500 benchmark index, raising concerns about concentration risk as these mega-cap companies continue pushing markets to record highs.
Damodaran, widely known as the “Dean of Valuation,” believes that mood and momentum have overtaken fundamental analysis as the primary drivers of these stocks, with bullish sentiment overshadowing traditional valuation metrics. He predicts that the unprecedented gains seen since 2023 cannot continue indefinitely, estimating some form of market correction in 2025. The professor points to historical patterns, noting that “every two or three years, something happens that’s big and global,” and expresses concern that current market pricing doesn’t adequately account for potential crises.
Despite these warnings, Damodaran has notably shifted his stance on tech stocks. In mid-2023, he famously sold his Nvidia stake, warning the chipmaker was pushing sustainable valuation limits. Since then, Nvidia shares have surged 179% year-to-date, with the company continuing to deliver blowout quarterly profits. Damodaran now acknowledges Nvidia as the sole company genuinely profiting from artificial intelligence, given its dominant position in creating hardware for AI applications.
The professor’s current recommendation is counterintuitive: investors should use any market correction as an opportunity to increase exposure to these tech giants. He suggests adding “at least one, maybe two or three of these companies” to portfolios, emphasizing their fundamental role in driving both the economy and markets. Damodaran describes these firms as “insanely profitable” and notes their market leadership shows no signs of weakening.
What makes these companies “special,” according to Damodaran, is their ability to scale revenue and growth while pursuing AI opportunities. He characterizes them as unprecedented “cash machines” from a value investing perspective, stating he’s “never seen cash machines as lucrative as these companies are” and doesn’t foresee their profitability slowing down. This assessment reflects the transformative impact of AI technology on big tech’s business models and profit generation capabilities.
Key Quotes
If you think about everything that’s happened since 2008, the one thing we know almost as a constant, every two or three years, something happens that’s big and global, and I think you need to build that in. And the fact that the market is not building in is a little troubling — what happens when you have that crisis?
Aswath Damodaran expressed concern about market complacency regarding the Magnificent Seven’s valuations, warning that investors aren’t adequately pricing in the risk of global disruptions that historically occur every few years.
I’d suggest that when that happens, you find a way to add at least one, maybe two or three of these companies, because these are so much a part of what drives the economy and the market.
Despite warning about potential corrections, Damodaran recommends using market downturns as buying opportunities for the AI-driven tech giants, emphasizing their fundamental importance to economic growth.
If you’re thinking as a value investor, I’ve never seen cash machines as lucrative as these companies are, and I don’t see the cash machines slowing down.
The NYU professor highlighted the unprecedented profitability of the Magnificent Seven, particularly their AI-driven revenue streams, marking a significant shift from his earlier skepticism about tech valuations.
Our Take
Damodaran’s reversal on tech stocks represents a crucial inflection point in AI investment thesis. His admission that he underestimated Nvidia—after selling before a 179% rally—demonstrates how AI’s commercial impact has exceeded traditional valuation frameworks. The distinction he draws between Nvidia’s actual AI profits versus other companies’ AI aspirations is particularly astute, highlighting the gap between AI hype and monetization reality. His “buy the dip” recommendation, despite bubble warnings, suggests that AI infrastructure has achieved critical mass as economic foundation rather than speculative bet. This validates the view that we’re witnessing a genuine technological shift, not merely momentum trading. However, his concentration risk concerns remain valid—when one-third of the S&P 500 depends on AI narrative sustainability, any crack in that story could trigger cascading effects across markets.
Why This Matters
This analysis from one of Wall Street’s most respected valuation experts carries significant weight for the AI investment landscape. Damodaran’s evolution from Nvidia skeptic to cautious tech bull illustrates how AI’s commercial viability has exceeded even conservative expectations. His warning about concentration risk is particularly relevant as the Magnificent Seven’s dominance creates systemic vulnerabilities in major indices—if AI hype deflates, the broader market could suffer disproportionate damage.
The acknowledgment that Nvidia is the only company truly profiting from AI raises important questions about the sustainability of AI valuations across the tech sector. While companies rush to demonstrate AI credentials, actual monetization remains elusive for most. This creates a bifurcated market where hardware providers capture immediate value while software and application companies bet on future returns.
For investors and businesses, Damodaran’s “buy the dip” strategy suggests that despite frothy valuations, the AI revolution’s fundamentals remain sound. His emphasis on these companies as economic drivers underscores AI’s transformation from speculative technology to core infrastructure, with implications for capital allocation, competitive dynamics, and long-term market structure.
