Big Tech’s blockbuster earnings have sent stock futures soaring, but a leading financial expert, Nigel Green, CEO of deVere Group, is sounding the alarm about a deceptive market.
US and European stock futures climbed Thursday after impressive earnings from tech giants.
Microsoft and Meta have delivered stellar quarterly results, fuelled by massive investments in artificial intelligence (AI). Microsoft reported $76.4 billion in quarterly revenue, up 18% year-on-year, driven by soaring demand for its cloud and AI services. The company announced plans to pour over $30 billion into AI infrastructure this quarter alone.
Meta, meanwhile, saw its stock surge 11% in after-hours trading. The social media giant posted a 22% revenue surge and a 36% jump in net income, signalling a deeper commitment to AI development.
These results reflect the ongoing AI arms race. Companies are racing to build cutting-edge infrastructure and services, fuelling investor excitement. The market responded enthusiastically, with tech stocks driving broader index gains.
But beneath the surface, cracks are forming, according to deVere Group’s CEO.
Green warns that the market’s heavy reliance on a handful of tech giants could spell trouble. While the AI boom drives optimism, the underlying market structure is increasingly shaky, raising concerns about overvaluation and fragility.
He cautions that the market’s structure is becoming dangerously lopsided. “This is not a tech bubble – yet,” Green said in a statement. “But several classic warning signs are flashing. Valuations are elevated, market leadership is dangerously narrow, and sentiment is being driven more by momentum than discipline.”
The S&P 500, often seen as a diversified benchmark, is increasingly dominated by a few players. Big Tech accounts for 32% of the index, while Communications Services, including Meta and Alphabet, add another 9.6%.
Together, these sectors make up over 41% of the S&P 500. The top 10 companies now represent nearly 40% of the index’s market capitalisation, a level of concentration surpassing the dot-com boom’s peak in 2000.
“The S&P 500 is no longer the broad, diversified index people think it is. It has become increasingly dominated by a small group of companies,” Green warned. “Investors are often unaware that they’re excessively exposed to the same handful of names.”
Nigel Green’s valuation concerns and market fragility
The market’s reliance on a narrow group of stocks raises red flags. Valuation metrics are starting to echo those seen in previous periods of overexuberance. The S&P 500’s forward price-to-earnings ratio exceeds 21, while tech-specific metrics like price-to-sales and price-to-cash flow are at historically high levels.
These figures suggest that investor optimism may be outpacing fundamentals.
Green acknowledges the strength of Big Tech’s earnings. “The AI growth story is real, and the earnings are real,” he said. “But that doesn’t mean the current pricing is always justified.” He points out that some leading companies are trading on overly optimistic expectations.
A single disappointing earnings report could trigger a broader market correction, given the concentrated leadership.
Green’s warning isn’t about abandoning tech or betting against AI. Instead, it’s a call for balance. “Portfolios must be positioned to withstand both continued upside and the inevitable periods of volatility,” he advised. Many investors believe they’re diversified but are heavily exposed to a few mega-cap stocks due to the structure of major indices.
The deVere Group CEO urges investors to reassess their portfolios now. “Now’s the time to act, not when it’s too late to do anything about it,” Green concluded. He recommends spreading investments across sectors and asset classes to reduce risk. This approach ensures portfolios can weather potential corrections while still capturing growth opportunities.
The current market dynamics draw comparisons to the dot-com bubble of the late 1990s. Back then, tech stocks soared on hype around the internet’s potential, only to crash when valuations proved unsustainable. While today’s AI-driven rally is grounded in tangible earnings, the concentration of market power mirrors that era’s excesses. Green’s cautionary call highlights the need for vigilance to avoid repeating past mistakes.
For now, the AI boom shows no signs of slowing. Companies are doubling down on investments, and markets are rewarding their ambition. But Green’s warning serves as a timely reminder: no stock, no matter how dominant, is immune to volatility.
Investors must balance optimism with discipline to navigate the stretched market landscape.
