• The recent equity rally, fueled by strong earnings and lower yields, faces a critical test from geopolitical tensions and key economic data.
  • Momentum in high-flying AI stocks is showing signs of fading due to weak new models and paused projects, despite resilient cloud spending.
  • While mid- and small-cap earnings growth is projected for late 2025, the firm cautions that similar optimism a year ago failed to materialize.

Raymond James has issued a caution that the S&P 500's robust performance is entering a precarious phase. The rally, which has been underpinned by stronger-than-expected corporate earnings, a decline in Treasury yields, and subdued oil prices, now confronts a series of immediate hurdles that could spark volatility.

According to the firm's analysis, the post-Labor Day period brings with it significant event risk. Key among these are escalating geopolitical tensions, the imminent release of new U.S. jobs data, and potential bond market turbulence stemming from a recent court ruling on Trump-era tariffs. The market's reaction to these developments, particularly how yields respond to shifts in trade policy, is seen as a major unknown that could quickly reverse recent gains.

Adding to the uncertainty is a noted cooling in the artificial intelligence sector. While cloud infrastructure spending remains a bright spot, analysts point to concerns over weaker-than-anticipated new model launches and several high-profile projects being put on hold. This fading momentum suggests that the tech giants that have powered the rally may be losing their upward thrust.

Looking further out, Raymond James anticipates a pickup in earnings growth for mid- and small-cap companies, though the timeline is pushed to late 2025 into 2026. The firm was quick to temper this outlook with a note of skepticism, recalling that a similar forecast for a broadening of the market rally was made a year ago and ultimately did not come to pass. This historical precedent underscores the challenges in predicting a sustained rotation away from mega-cap dominance.

The coming weeks will serve as a critical stress test for the market's resilience. Investors are advised to monitor the incoming jobs data for signs of labor market softening and to watch the bond market closely for any adverse reaction to trade policy uncertainties. A breakdown in these areas could quickly undermine the pillars of strong earnings and lower yields that have supported stocks.
