[02:12–02:49]

• Context: Seven stocks (Nvidia, Apple, Microsoft, Amazon, Meta, Alphabet, Tesla—dubbed “The Magnificent Seven”) now account for over a third of S&P 500 value, largely thanks to AI optimism.

Interview: Dean Smith, Chief Strategist at Folio Beyond

[02:49–06:15]

• Are the “Magnificent Seven” overvalued?

  • “The stocks that make up the Mag 7 have really taken on a life of their own…Anytime you get above 100 times earnings, you're into speculative territory.”
    — Dean Smith [03:03]

• Why the increased caution now?

  • Smith highlights that while core AI technological progress is real (from software models to data centers), business adoption is proving more challenging and slow than expected.
  • “That's turning out to be much, much harder.”
    — Dean Smith [03:38]

• Dot-com bubble vs. AI surge—a fair comparison?

  • Smith distinguishes the present from the late-90s bubble, calling out differences in depth and reality of AI innovation versus the more superficial dot-com craze:
  • “In the case of the dot com bubble, everybody wanted to be something or other.com and a lot of that was just nonsense. ... The AI revolution is something different.”
    — Dean Smith [04:24, 04:53]

• Agentic AI as the major shift

  • Emerging "agentic" AI systems can autonomously run, write software, and manage business tasks—seen as a foundational difference from generic internet businesses.
  • “These agents, they can run software, they can write software, they can do accounting functions…that go far beyond simply asking ChatGPT a question.”
    — Dean Smith [04:53]

• Is this a bubble—yes or no?

  • Smith’s take: While stocks may be priced at unsustainable, speculative levels, the underlying AI technology is fundamentally sound and transformative.
  • “To the extent there’s a bubble, if you want to call it that, it's there. It’s in the valuations. It's not in the AI technology itself.”
    — Dean Smith [05:34]

4. Tariff Change on Imports Under $800

[06:16–06:58]

• Announcement: The "de minimis" tariff exemption for packages under $800 entering the US (except from China) ends, affecting e-commerce businesses and online shoppers.
