Insider buying across US stocks has fallen to its lowest level in at least 21 years, and it fell in the same window a leveraged AI hedge fund was forced to liquidate
Only around 14.8% of companies with recent insider transactions show net buying, a reading that would mark a two-decade low if it does not improve by month-end, arriving alongside Situational Awareness's forced unwind of a four-times-leveraged AI portfolio.
Two data points landing in the same week do not automatically explain each other, but the correlation here is hard to wave away. Corporate insiders, the people with the best information about their own companies and no obligation to publicize their reasoning, have been net sellers at a rate not seen in at least 21 years, right as a hedge fund built on concentrated AI-thematic longs and four times leverage was forced to dump its public portfolio to Citadel. That is not proof of causation, but it is exactly the kind of signal that tends to precede, rather than follow, a broader repricing.
The mechanism worth understanding is what leverage does to a concentrated thematic bet when it goes wrong. Situational Awareness reportedly returned 439% in the first half of 2026 running a four-times-leveraged book concentrated in AI winners and AI-loser shorts. That leverage was the entire engine of the outsized returns on the way up, and it became the entire mechanism of the forced unwind on the way down, once its top AI longs fell 40 to 50% in a single month. A fund does not choose to liquidate at that scale; margin calls choose for it, on whatever schedule the market sets rather than the manager's own view of value.
What insiders selling into strength usually signals is not necessarily disbelief in AI as a technology story, but skepticism about how much of the current valuation is durable versus how much is leverage-inflated momentum chasing itself. Insiders are typically diversifying into low-volatility, dividend-paying names rather than making a directional call against AI outright, which is a more mundane explanation than a coordinated bearish signal, but it is also the kind of quiet positioning shift that only becomes visible in aggregate data like this.
For anyone reading the Situational Awareness story as an isolated blow-up by an overleveraged 24-year-old fund manager, the insider-selling data is the reason not to file it away that easily. A 21-year low in insider buying means the people closest to the underlying companies, across the market broadly and not just in one fund's book, are behaving as though the AI trade's valuation cushion has gotten thin. Leverage amplified one manager's exposure to that thinness into a forced liquidation; it did not create the thinness itself.
