After days of sell-offs, nearly everyone—from Wall Street to retail investors—has been vigorously defending AI investments, presenting highly persuasive arguments.

However, multiple indicators suggest that AI investments have reached extreme levels. Holdings in large-cap growth and tech stocks have rebounded to multi-quarter highs, while hedge funds' preferred stocks now align closely with those favored by speculative retail traders. More alarmingly, household equity exposure has hit a record high. If AI-driven tech valuations crack, the wealth effect alone could drag U.S. GDP down by 2.9%.

**Mag 7 Option Skew Remains at Historic Highs** The option skew for big tech stocks has reached the 91st percentile. LSEG data shows that the three-month 25-delta call skew for the "Magnificent Seven" (Mag 7) tech giants is at historic highs since May 2012, reflecting extreme investor optimism about further upside.

**Tech Holdings Surge Back** Deutsche Bank data further confirms this trend. Large-cap growth and tech holdings have returned to multi-quarter highs, signaling heavy capital inflows into the sector.

**Hedge Funds and Retail Traders Now Indistinguishable** The most striking shift is in hedge fund behavior. Empirical Research Partners notes that fundamental hedge funds have "embraced high-beta stocks"—namely, the AI darlings of big tech. In other words, hedge funds now favor the same stocks as speculative retail traders, creating a dangerously crowded trade among both professional and speculative investors.

**A Pullback Could Be Healthy?** Historical data shows that AI-related stocks have experienced multiple sharp corrections relative to the broader market before being bought on dips. Goldman Sachs analysis confirms that AI investments are not a one-way bet.

**Record-High Exposure Risks** More concerning is the broader economic risk. Household equity allocations are at record levels, and estimates suggest that a crack in AI-driven tech valuations could reduce GDP by 2.9% through wealth effects alone. The U.S. economy's reliance on AI has reached precarious levels.

**Systemic Risks Intensify** Industry concentration is another red flag. CB Insights data reveals that Nvidia underpins nearly every major AI player except Anthropic. This hyper-concentrated supply chain amplifies systemic risks.

**History Rhymes Alarmingly** Top Down Charts presents an "astonishing comparison"—current conditions bear an eerie resemblance to past bubble periods. Such extremes rarely end well.

**Narrative Whiplash** The rapid shift in market narratives is also concerning. From "search is dying" to "Google is actually an AI leader," the 180-degree flip in sentiment highlights market instability.

**Credit Risk Divergence** Finally, credit risk indicators are diverging. Tech sector credit risk has surged, while banking remains relatively calm. Though specific factors apply and the "credit always leads" rule shouldn’t be oversimplified, this divergence warrants close monitoring.

When everyone believes the same story, the market is often preparing for a reversal.
