Why JPMorgan Says the Latest AI Stock Slump Won't Bounce Back Like July

The short version

JPMorgan's Global Markets Strategy team, led by Nikolaos Panigirtzoglou, released a capital flows and liquidity report on October 14, 2026, outlining why an immediate AI stock rebound is unlikely.

During July 2026, the PHLX Semiconductor Index (SOX) fell 21% before staging a fast, V-shaped recovery driven by retail dip-buying, active corporate buybacks, and short sellers closing bearish bets.

AI stocks lost more than $1 trillion during the October sell-off, which heavily impacted memory chips, South Korean chip stocks, and the KOSPI index.

Unlike the summer dip, current market conditions feature stalled corporate buybacks, low short interest, and amplified downside pressure from leveraged ETFs.

What is different about the October AI sell-off?

JPMorgan's Global Markets Strategy team reported on October 14, 2026, that the current downturn in artificial intelligence infrastructure stocks lacks the fundamental and technical support systems that enabled a swift recovery earlier in the year. Published reports from Crypto Briefing and Streamline Feed highlighted that AI stocks lost more than $1 trillion during the October slide, which hit memory chips and South Korean stocks particularly hard.

In July 2026, the PHLX Semiconductor Index (SOX) dropped 21% in what marked its worst monthly performance since October 2008. That July correction was quickly erased through a V-shaped recovery. According to JPMorgan strategists, however, the catalysts that saved the summer market are absent this time around.

Why retail investors and corporate buybacks have stalled

Retail enthusiasm and corporate capital allocation strategies have shifted significantly since the summer dip. Crypto Briefing and Streamline Feed noted that retail investors have not returned to the market with the same vigor seen in July. At the same time, corporate buyback programs have stalled as cash-rich technology giants conserve capital to fund massive AI infrastructure expenditures, including semiconductor procurement and data center construction.

Furthermore, technical market dynamics have changed. Short interest remains low, removing the potential for a powerful short squeeze that would otherwise force bearish traders to buy back shares. Meanwhile, the proliferation of leveraged exchange-traded funds is amplifying downward price movements through daily rebalancing and forced selling. Financing costs have also climbed, with widening credit default swap spreads reported on major exposed names such as Oracle and SoftBank.

What investors should watch next

Driven by these shifting dynamics, JPMorgan strategists advised a cautious path for technology equities and consider a rapid rebound unlikely. According to analysis covered by Crypto Briefing and Streamline Feed, market participants are advised to monitor specific financing indicators closely:

Data-center debt costs and rising credit spreads on exposed infrastructure names
Operating cash flows and clear monetization strategies rather than broad passive exposure
Companies demonstrating operational leverage instead of relying purely on speculative growth narratives

Tech-focused hedge funds lost more than 10% in their technology, media, and telecom strategies during the prior period, intensifying the cautious sentiment across Wall Street.
