The psychology of artificial intelligence

AI-related stocks span chipmakers, cloud infrastructure providers, software companies building AI features, and speculative pure-plays with limited current revenue. Sector enthusiasm has produced some of the sharpest sentiment swings of any recent theme.

Worth checking before you act on it:

• Whether the company has real, growing AI-related revenue today, versus being valued mainly on future potential or association with the theme.
• How concentrated the company's AI exposure actually is, some companies get "AI" attention despite it being a small part of their business.
• Margin trends, since AI infrastructure buildout can be capital-intensive in ways that pressure near-term profitability even for real beneficiaries.
• Whether a stock's recent move tracks a specific company announcement or just broad sector sentiment.

1. Assuming sector enthusiasm distributes evenly. A rising theme lifts some names on real fundamentals and others purely on association, and the gap between the two only becomes obvious after a correction separates them. Treating every AI-adjacent name as equally justified by the theme is a common way a real trend still produces avoidable individual losses.
2. Sizing a basket the same regardless of fundamental exposure. A basket of AI-adjacent names bought on the same thesis, without differentiating between companies with real revenue exposure and companies riding sentiment alone, gets hit far harder in a correction than the fundamentals alone would suggest, since the position wasn't sized to reflect that difference in advance.
3. Treating every earnings beat as validation of the whole theme. One company's strong AI-related quarter doesn't confirm the thesis for every other name in the sector, but it's commonly treated that way in the moment.
4. Ignoring valuation because the theme feels too big to be wrong. A real long-term trend can still support a wildly overpriced individual stock in the short term, and "the theme is real" isn't the same argument as "this specific valuation is reasonable."

• Check what share of a company's actual revenue is AI-related before trading it as a pure AI play.
• Differentiate position sizing within a thematic basket based on fundamental exposure, not just sector membership.
• Separate "is the theme real" from "is this specific valuation reasonable" as two different questions.
