Investors enjoying another strong year in stocks may want to pay closer attention to warning signs emerging across the market.
According to a recent analysis from Bank of America, a growing number of indicators commonly associated with market downturns have begun flashing caution signals. The bank’s strategists believe the stock market may be approaching a period of increased volatility, prompting recommendations for investors to consider taking profits while valuations remain elevated.
The warning comes after seven of the bank’s 10 bear market indicators were triggered in recent months. Five signals turned negative by April, while two additional indicators crossed warning thresholds in May.
More bear market indicators have turned negative
Bank of America’s monitoring system tracks a variety of market conditions that have historically appeared before major market corrections.
These indicators measure factors including consumer confidence, expectations for stock performance, credit market stress, and lending conditions.
The latest update shows that 70% of the bank’s tracked warning signals are now active. Strategists led by Savita Subramanian noted that the increasing number of alerts suggests investors should prepare for the possibility of weaker market performance ahead.
Signs of speculative behavior are growing
One of the indicators attracting attention involves the performance gap between expensive and inexpensive stocks.
Bank of America found that companies with high price-to-earnings ratios have significantly outperformed lower-valued stocks. Analysts view this type of market behavior as a potential sign of excessive speculation.
The bank also observed that long-term growth expectations have climbed to levels that historically left stocks more vulnerable to disappointment if earnings fail to meet investor expectations.
The S&P 500 remains historically expensive
Despite ongoing concerns about valuations, the broader market has continued moving higher in 2026.
The S&P 500 has gained roughly 8% this year. However, Bank of America believes the benchmark remains expensive when measured against many historical valuation metrics.
According to the firm’s analysis, the index currently trades at elevated levels on 17 out of 20 valuation measures reviewed by its research team.
Those findings have increased concerns that future gains could become harder to achieve if corporate earnings growth slows or economic conditions weaken.
Technology stocks are showing wider performance gaps
The technology sector continues to dominate the stock market, but analysts say performance differences within the group are becoming increasingly noticeable.
Bank of America reported that the gap between the strongest-performing and weakest-performing technology stocks has reached its widest level since February 2000, shortly before the dot-com bubble burst.
While today’s technology companies generally have stronger fundamentals than many firms during the internet boom era, several important financial trends appear to be weakening.
Key technology fundamentals are deteriorating
The bank highlighted several areas that deserve attention from investors.
Cash flow conversion rates have flattened. At the same time, investment-grade debt issuance and equity offerings have increased.
Stock buybacks, which often help support share prices, have slowed relative to overall market value. Meanwhile, capital spending by major cloud computing and artificial intelligence companies is expected to approach 100% of operating cash flow by the end of the year.
These developments have raised concerns that rapid spending growth could eventually pressure profitability.
Opportunities remain despite broader concerns
Bank of America is not suggesting that every stock faces immediate downside risk.
Instead, strategists believe investors should be selective. The firm continues to see opportunities among individual companies even as concerns about the broader market increase.
Subramanian has set a year-end target of 7,100 for the S&P 500. That forecast sits below the roughly 7,400 level where the index recently traded, reflecting expectations for a more challenging environment during the second half of the year.
As warning signals continue to accumulate, investors may face a market that rewards careful stock selection rather than broad exposure to major indexes.
