Wall Street's major indexes continue to hover near record levels, but beneath the surface, the foundation of the rally appears increasingly fragile. A multi-week pullback has interrupted a string of weekly gains, and JPMorgan Chase & Co. believes this retreat is more than a routine pause.
In a note from technical strategist Jason Hunter, the bank argues that the apparent strength in the indexes masks a shift in market internals and leadership that historically precedes trouble. The trigger, in JPMorgan's view, is not economic data but the slow unraveling of conviction in artificial intelligence stocks—the same trade that has powered much of this year's gains. That unraveling is arriving just as seasonal patterns turn historically unfavorable.
Why JPMorgan recommends caution
On the surface, nothing looks broken. The major indexes remain in a bullish trend, and no single signal has flashed a clear warning. What worries Hunter is happening away from the index tape: how positioning has shifted inside the market, which groups are actually leading it, and how the assets that tend to turn first are behaving. Together, these signals resemble a topping process more than a healthy pause.
Late summer and early fall are historically the market's weakest stretch, and JPMorgan sees this backdrop compounding that seasonal risk rather than offsetting it. The gap between calm index-level performance and deteriorating conditions underneath, in Hunter's framing, is the kind of setup investors tend to miss until it's too late.
A different kind of rotation
The retreat from artificial intelligence and broader technology names this summer differs from prior rotations in one key way: it lacks conviction. In the fourth quarter of 2025, capital leaving tech flowed into cyclical, pro-growth sectors, reflecting confidence in the economy. Hunter reads today's move differently: crowded positions are being trimmed, technology exposure pared back, and the proceeds landing in more defensive corners of the market—a pattern that looks like risk reduction rather than a fresh economic bet.
Hardware and hyperscale computing stocks tell a similar story, moving unevenly as investors question the payoff timeline on aggressive spending and struggling to reclaim resistance levels set earlier this year. That, in JPMorgan's view, is evidence that buyers haven't fully returned. For context, Nvidia's recent dip highlights the sensitivity of AI-related names to spending concerns.
JPM now sees echoes of 2000s
JPMorgan's sharper warning rests on a historical parallel. Hunter says the AI trade's trajectory echoes the run-up to 2000, when tech stocks surged for years before collapsing and dragging the market into a prolonged downturn. The echo extends to the spending cycle underneath it: the late-stage communications equipment buildout of that era faced similar doubts about payback, much like today's AI infrastructure spending does now.
None of this guarantees a repeat, Hunter notes, but as trading enters a period historically prone to volatility after Labor Day, he treats the parallel as a risk worth taking seriously. The bank's message, for now, is caution rather than capitulation—a reminder that fading conviction in the market's biggest trade rarely coexists with a rough seasonal window without consequence.
Investors may want to watch how the S&P 500's recent weekly drop evolves, and whether leverage risks in AI chips amplify any downturn. The coming weeks could test the resilience of the rally.
