JPMorgan Warns AI Stock Rally Lacks July‑Style Rebound, Citing Short Activity and Buyback Trends

New York, United States – JPMorgan’s research team has cautioned that the AI‑driven rally that surged in July may not replicate its momentum, citing a decline in short interest, the cessation of corporate buybacks, and an excess of long positions. The analysis suggests that the sector’s fundamentals have not shifted sufficiently to support a sustained rebound.

Short Activity Declines

The research notes that short interest in AI‑related equities has fallen by 12% over the past month, a trend that diverges from the July spike when shorts surged to 18% of float. According to JPMorgan’s data, the decline in shorts signals a reduced bearish stance among institutional investors, but also indicates that the sector may be overvalued.

Buyback Trends

Corporate buybacks, a key driver of share price support, have largely ended across major AI firms. JPMorgan’s analysis shows that buyback activity dropped from 4.2% of earnings in June to 0.3% in September. The slowdown is attributed to higher capital expenditures and a shift toward research and development.

Long Positions and Inflows

Long positions have increased by 27% year‑to‑date, creating a 3:1 ratio of longs to shorts. The research team interprets this imbalance as a sign that the market may be saturated, with limited room for further upside. Additionally, inflows into AI ETFs have plateaued, with the largest fund reporting only a 1.5% net inflow in the last quarter.

Market Implications

The combination of declining shorts, halted buybacks, and a surplus of longs suggests that the AI trade may not experience a July‑style rebound. JPMorgan’s strategist recommends a cautious approach, advising investors to monitor short‑interest trends and corporate buyback announcements before committing additional capital.

The findings align with broader market sentiment, where analysts have expressed uncertainty about the sustainability of AI valuations. While the sector continues to attract attention, the lack of new inflows and the end of buyback programs could signal a plateau in price growth.

Investors should weigh the potential risks of overvaluation against the sector’s long‑term growth prospects. JPMorgan’s research underscores the importance of monitoring short‑interest dynamics and buyback activity as key indicators of future performance.
