A magician spent 10 years rigging card decks. then he became a Stanford professor and proved the market works the same way. he published the math for free. Wall Street still pretends nobody saw it.
his name is Persi Diaconis. his quote: "I've spent my life on two tricks. making a rigged deck look random, and making a random one look rigged. the market is the first trick, and almost nobody catches it."
the tilt is invisible to human intuition. a 50.75% edge buried inside what looks like pure chance. your gut reads a losing week as a broken system and a hot streak as skill. wrong both times. that's exactly why funds hand the decision to the math.
it takes thousands of trades for a 51% edge to separate from luck. almost everyone quits before then. the ones who didn't quit manage the money now.
Diaconis has taught this for decades. the probability goes back to 1713. the lecture is free.
the patience to trust it past your own eyes is the edge.
A billionaire went on stage and explained in 42 minutes how the entire economy works. for free. Wall Street spent the next decade pretending nobody saw it.
he didn't sell a course. he didn't plug a fund. he stood at a whiteboard and drew three lines that explain every crash, every recovery, and every rate decision since 1929.
MBA programs charge $200,000 to teach frameworks he covered in the first 15 minutes. six of the models he drew on that board are still classified as proprietary at three major banks. he gave them away on YouTube.
the part nobody talks about: he predicted exactly what happened in 2020, two years before it played out. interest rates hitting zero, the central bank running out of tools, the money printer. he drew it on a whiteboard in 2018 like he was reading tomorrow's newspaper.
a portfolio manager at a top-five firm told me every new analyst on his desk watches this before they're allowed to open a terminal. not the CFA prep. not the internal training. this one lecture.
40 million people have seen it. almost none of them can name the three forces he draws in the first ten minutes.
it is still free.
neither honestly. debt service ratios are near historic lows and household net worth just crossed $180T, that's not deleveraging. but core inflation's stuck above target with credit card debt hitting record highs, that's not the calm middle either. feels more like the boom-before-the-correction stage than either extreme you named.
not financial advice, just reading the same indicators anyone can pull
@juanitaaaaa that's the real skill actually, most people can spot a bubble after the fact, almost nobody can make the mechanism this obvious in real time
@WmweakleyWalter fair, though the hard part was never the formula, it's people refusing to bet less than f* tells them to when they "just know" they're right

An Indian professor at IIT recorded one lecture on probability. no editing, no thumbnail, one chalkboard.
Wall Street charges $500,000 for what he gave away for free.
160,000 people watched him define a coin flip properly. almost none of them ever traded on it.
his subject is the axioms under every bet. what a probability actually is, before you dare size a position on it. every quant in 2026 is standing on this, most just skipped the lecture.
Jagannathan teaches this to the IIT engineers who end up on the desks. no upsell, no thumbnail. the foundation of your whole post sits there with fewer views than a phone review.
skip to where he refuses to hand-wave. he builds "the chance of heads" from the ground up, slow, rigorous, the way the people who keep the money were taught.
no ticker. no hype. one chalkboard and the axioms.
a quant I know says half his desk learned probability from this exact free course, not from their finance degree.
you are a decade late. it is still free
