Bank of America is warning investors that the U.S. stock market may be approaching a more vulnerable stage after a powerful rally pushed major indices toward record highs.
In a June 5 research note, strategists led by Savita Subramanian advised investors to consider taking profits as a growing number of historical bear-market indicators are now flashing warning signs. According to the bank, approximately 70% of its monitored bear-market signals have been triggered, a level that closely matches conditions observed near previous market tops.
The warning comes as the S&P 500 continues to trade near elevated levels, supported by strong corporate earnings, enthusiasm surrounding artificial intelligence, and robust investor participation.
A key concern highlighted by Bank of America is valuation.
The firm’s analysis found that the S&P 500 is statistically expensive on 17 of 20 valuation metrics currently being tracked. On eight separate measures, the index is trading at richer levels than those recorded during portions of the technology bubble era.
While elevated valuations alone do not necessarily trigger market declines, they can reduce future return potential and increase market sensitivity to unexpected economic or earnings disappointments.
The bank noted that investor optimism, improving merger-and-acquisition activity, and easing credit conditions have all contributed to the current environment, but these factors are now being accompanied by increasing signs of market excess.
Bank of America also pointed to growing concentration and speculative behavior within the technology sector.
According to the analysis, the performance gap between the strongest and weakest technology stocks has widened to levels not seen since early 2000. The divergence suggests investors are aggressively chasing a narrow group of market leaders while many other companies lag behind.
The bank further noted that the S&P 500’s headline gains may be masking significant internal dispersion beneath the surface. The spread between the best-performing and worst-performing stocks within the index recently reached its highest level since the post-pandemic period began.
Such concentration can create instability if market leadership begins to weaken.
While many technology companies continue to benefit from strong artificial intelligence demand, Bank of America highlighted several emerging concerns.
Cash flow conversion among major technology firms has flattened, while both investment-grade debt issuance and equity issuance have increased. At the same time, share buyback activity as a percentage of market capitalization has slowed.
Perhaps most notably, capital expenditures among hyperscale technology companies are expected to approach nearly 100% of operating cash flow by the end of 2026, up dramatically from approximately 40% in 2023.
The trend reflects the enormous infrastructure investments being made to support AI development but also raises questions about long-term returns on those investments.
Despite the cautionary outlook, Bank of America is not forecasting an immediate collapse in equities.
Instead, the firm argues that investors should become more selective rather than relying on broad index exposure. The bank continues to identify opportunities in individual companies where fundamentals, valuations, and earnings prospects remain attractive.
Subramanian maintained a year-end S&P 500 target of 7,100, which sits below recent index levels near 7,406. The forecast suggests limited upside for the broader market while emphasizing the importance of stock selection.
Bank of America’s latest warning adds to a growing debate on Wall Street regarding whether the AI-driven bull market can continue at its current pace. While strong earnings growth and technological innovation continue to support equities, the bank believes rising valuations, speculative positioning, and increasing market concentration warrant a more cautious approach.
For investors, the message is not necessarily to abandon equities altogether, but to recognize that risk-reward dynamics may be becoming less favorable after an extended rally.
