About 1% if even that, I believe.

1 billion Jews is ridiculous, though, it'd be one in eight humans on earth. Perhaps in certain parts of America it feels that way - Rogan likely has disproportional contact with intelligent, unusual people and maybe that skews his estimates. But Israel would have to be the size of China.

About 1% if even that, I believe.

I think you have over-corrected here. It's more like 5-15% before fees and 5-10% after fees. They (professional investors and fund managers) are largely, in Peter Lynch's words, 'oxymorons', but it's not quite as bad as you suspected. Funnily or appropriately enough, the percentage lines up almost exactly with the percentage of amateur traders who succeed consistently. Yet so-called professionals and those with credentials are consistently awarded more credibility and respect.

That isn’t quite true. “Amateur investors” includes everything from sensible people who manage their 401ks with a little panache and a slight preference in sector exposure to “day traders” of the WSB type who gamble on far out of the money options or who put their life savings into heavily leveraged short ETFs.

Among the latter, most data shows perhaps 1% make money consistently, far below professional active managers. In addition, their losses are far higher, while many active managers (loathe as I am to defend them) only marginally underperform the market.

I did not say amateur investors (the larger group). I said amateur traders, who attempt to take their activities quite seriously. Around 10% of them succeed consistently, afaik.

What separates a trader from an investor? You can discuss this professionally (traders execute to balance liquidity, market depth, optimize, PMs strategize, order etc), but its not relevant to amateur investing where the PM/trader distinction is definitionally irrelevant.

Rogan is a stand up comedian, 1/8 professional comedians are probably Jewish.

Best explanation!

In New York City, I think about a quarter of white people are Jewish. In LA it is much lower, though maybe 1/8th still makes sense.

YouGov says (link above) Americans think 30% of US people are Jewish. In reality, about 10% of New Yorkers and about 2% of Americans are Jewish (which would make it about 20% of whites in NY, though there are non-white Jews, but not too many of them in New York I presume). And this likely including people who have any Jewish genes, about half of them probably do not have any connection to Jewish culture or religion - though in New York due to large Orthodox population likely the distribution is a bit different.

That said, for comedians specifically I'd say 1/8 is probably low, could be as high as 20% if you count successful professional comedians, though I haven't seen any exact or well-supported figures anywhere.

Fair.
