Interesting... There is so much evidence about it, but you know better. "But muh lambo and trading educator $2999 course!".
Taiwan (entire country): 99% of day traders are individual investors, most of the other 1% are corporations (hedgers, insiders, idk)
Almost all of them lose (I suspect the few ones that make money are the ones that run pump & dumps), the "winners" barely make anything, losers lose way more than what the pump and dump ones make, and there is 0 learning they do not perform better the longer they have been trading (giving additional proof the handful that make money did not learn how to but simply cheat).

Brazil (entire country day traders in the indice mini future - 10 times the e-mini volume): The longer they trade the more they lose, of those that traded 300+ days 97% lost money including big losses, very few made more than minimum wage, and the most "successful" one - in the entire country - made a whooping 300 bucks a day with enormous risk (over 2000 daily volatility - when he stops "winning" he will blow up fast)

An average institution: Academics looked at the intraday trading results of a bank and found that they made 0 money day trading

Prop firm: Academics looked at a prop day trading firm in 1999, the golden era of day trading, and what a surprise they found that on average the day gamblers lost 750 a day, the most "profitable" one made $197,000 and the biggest loser lost 748,000. Looks like a normal distribution in a losing game to me...

The SOES bandits made money. At the absolute peak of the dot com bubble there was a period of a couple of weeks where about half a day gamblers were able to make money - but infinitely less than if they held their trades. Other than this day gamblers never make money. Never have never will. At best there will be miracle periods of a few weeks where they randomly make some money but again far less than if they were real investors.
But I am pretty sure the clowns that call themselves day traders will never be profitable. If there ever is an edge quant traders that understand statistics, mathematical finance, and are always on the lookout for a flaw with an army of computers and algos, will arbitrage the fuck out of any intraday obvious edge. They are pushing the technology to the limit and fighting for pennies - which they scale to the max taking hundreds or thousands of trades a day. And quants are not making hundreds of percent returns a year that retail day gamblers dream of. They make returns similar to regular investors, if they made much more then more people would get into quant trading and the edge would get smaller and their returns too.
So all those quants are driving lambos taking $$$ from day traders ?
