"Most people might just as well buy a share of the whole market, which pools all the information, than delude themselves into thinking they know something the market doesn't"
About this Quote
The intent is practical and a little merciless. “Pools all the information” is efficient-markets theory in plain clothes: prices are not random guesses but compressed judgments, updated constantly by armies of professionals with capital, data, and motive. Against that, the small investor’s conviction starts to look less like insight and more like what Miller calls it: delusion. The word choice matters. He’s not accusing you of ignorance; he’s accusing you of self-deception, the particularly human habit of mistaking confidence for edge.
Subtext: even if you do know something, converting that “something” into outperformance is hard once you include costs, taxes, and timing. The market doesn’t just need to be wrong; it needs to be wrong in a way you can monetize before everyone else corrects it. That’s a vanishingly narrow target.
Contextually, Miller’s career sits inside the postwar revolution in financial economics - the same intellectual current that produced the Efficient Market Hypothesis, CAPM, and the case for passive investing. Read now, it lands as both advice and cultural critique: a rebuke to the retail-trading dopamine economy and the moral of every “I beat the market” anecdote that forgets to subtract luck.
