Investor poll finds Wall Street's worries over a tech bubble have yet to reach extreme levels

A recent Deutsche Bank investor survey indicates that while Wall Street's perception of U.S. tech bubble risk remains elevated, it has not reached the extreme levels observed in 2021, with the AI narrative now providing a valuation justification absent during the prior zero-rate environment. Despite this, concerns are rising regarding AI spending, particularly for the "Magnificent Seven" stocks, even as U.S. credit spreads are at 27-year lows. The survey also highlights a significant increase in investors utilizing AI for work, underscoring its rapid integration into professional practices.

Analysis

A third-quarter Deutsche Bank survey indicates that while investor perception of a U.S. tech bubble remains high, it has not escalated significantly in 2025 and is still below the peak seen in 2021. The key distinction from the 2021 period is the underlying narrative; whereas zero interest rates formerly justified valuations, the current market is buoyed by the artificial intelligence growth story. This AI narrative provides a fundamental basis for current valuations that was previously absent. However, concerns are mounting around the magnitude of AI-related capital expenditures, particularly highlighted by deals like the tentative pact between OpenAI and Nvidia, with bubble fears running slightly higher for the 'Magnificent Seven' stocks specifically. This sentiment contrasts with the broader credit market, where U.S. credit spreads are at 27-year lows, signaling minimal investor concern over corporate defaults. The survey also underscores the rapid integration of AI into professional workflows, with only 18% of investors now reporting non-use for work, a sharp decline from 48% a year ago.

Key Decisions for Investors

• Investors should consider maintaining selective exposure to U.S. technology, as the AI narrative provides a more fundamental support for valuations compared to the zero-rate environment of 2021, although bubble perceptions warrant caution.
• It is prudent to closely scrutinize the capital efficiency and return on investment for AI-related spending within large-cap tech, as this is an emerging source of investor concern despite the overall bullish AI theme.
• Monitor the significant divergence between elevated tech equity bubble fears and historically low U.S. credit spreads; a widening of these spreads could be a leading indicator of a broader risk-off shift that would negatively impact the technology sector.
