Is AI a bubble? Don’t read opinions — read where the legends put real money
The “AI bubble” debate never settles. Instead of opinions, quantify the legends’ actual moves: the AI Conviction Index measures how strongly eight investors back AI this quarter, while the split on Nvidia shows the market is far from a single answer.
Why the bubble debate is unwinnable
Whether it’s a bubble depends on your valuation model and horizon — which is why it never settles. A more useful question: are the style-diverse legends who run real money **net adding or net trimming** AI this quarter? Actions are more honest than opinions.
Quantifying conviction into one number
The AI Conviction Index takes the mean Consensus Score across consensus names for a single 0–100 read of collective conviction, and flags whether net action is adding or trimming. It won’t call the top, but it shows at a glance whether the legends are piling in or quietly stepping back.
The disagreement is the answer
Nothing shows “no single answer” better than Nvidia: some add sharply while others trim. When even the hottest name is clearly split, the market has priced in a lot of expectation — and valuation discipline plus a long horizon matter more than whether to chase.
