Ken Fisher: What AI Tech Stocks Are Signaling About This Bull
Ken Fisher suggests tech stocks will likely continue performing well as the bull market transitions into an early euphoria phase. He points to the Cerebras IPO as a symbolic indicator of this shift, while noting the bull market is broader and more global than most recognize.
Summary
Ken Fisher opens by acknowledging that tech stocks have resurged after a weaker period and expresses a cautiously optimistic view that they will likely continue to perform well. He frames this within a broader thesis that the bull market is transitioning into its final phase, which he emphasizes could still last a considerable amount of time.
Fisher uses the recent Cerebras IPO as a concrete example of early euphoria entering the market. He describes the breathtaking post-IPO price appreciation as symbolic of the transition from the 'optimism' phase of a bull market into the early stages of 'euphoria' — a distinction he views as meaningful for understanding where we are in the market cycle.
Despite the bullish trajectory, Fisher acknowledges a range of ongoing concerns that investors are contending with: weak European economies, lingering tariff anxieties, geopolitical tensions such as the Iran conflict, and widespread political uncertainty. He argues that these worries coexist with rising markets and increasingly speculative valuations that have yet to be justified by underlying fundamentals.
Fisher closes by broadening the perspective, noting that global markets — including regions with no significant tech or AI exposure — have been hitting new highs. He argues this demonstrates that the bull market is a global phenomenon, far wider in scope than the tech-centric narrative most people focus on, and that he has been pointing this out consistently since 2023.
Key Insights
- Fisher argues that the Cerebras IPO's dramatic post-listing price surge is symbolic of the transition from the optimism phase of a bull market into the early stages of euphoria, marking a meaningful shift in market psychology.
- Fisher contends that the bull market is entering its final phase but stresses this phase can last a considerable time — potentially a couple of years — cautioning against interpreting 'final phase' as imminent collapse.
- Fisher observes that speculative valuations in AI and tech stocks require many things to happen just to begin justifying current price levels, yet once that speculative momentum starts, it tends to sustain itself until the cycle fully ends.
- Fisher claims that global markets, including those with little to no tech or AI exposure, have been hitting highs in 2023, 2024, and 2025, which he uses to argue the bull market is much broader and more globally distributed than the prevailing tech-centric narrative suggests.
- Fisher argues that persistent investor worries — including weak European economies, tariff concerns, the Iran conflict, and political uncertainty — are characteristic of the optimism-to-euphoria transition, where markets rise in spite of widely held fears.
