Adding to book:
Foundation of Risk Parity is, officially: 1) finite and KNOWN variance 2) ellipticality.

Problem: variance is not projectable since kurtosis is patently infinite.
No ellipticallity since infinite higher order moments.
Also problem of preasymptotic behavior. twitter.com/nntaleb/status/126

No, I did not block Marcos López de Prado @lopezdeprado because of his comments. I had blocked him weeks ago when I saw these claims in his bio. twitter.com/nntaleb/status/126

CHEATING: By simulation the base is ½ and converges quickly. We cannot use traditional methods because the "generator" function f has a second argument in it, here p. twitter.com/nntaleb/status/126

Mandelbrot has a monstrous scientific erudition & a yuuge curiosity. He knew arcane math stuff only autodidacts know.
But he respected erudition much more than scientific rank, based on his fascinations with polyglot characters like Jean de Menasce.

NARCISSISTIC RAGE: HOW ASNESS BLEW A FUSE

One shd resist making psychiatric claims, excepty for situations where 100% self evident.

Busted : 1) Fails to deliver claims, 2) Uses pseudoscientific analytics not for fat tails. =>Asness goes nuts.

Fama's reasons was that Fat Tails were "incompatible with the tools in social science".
It's like using the map of Tokyo in Mexico because "here is a map".
I actually wrote to Fama & got same HORRENDOUS answer.

Mandelbrot saw Fama never understood the CONSEQUENCES of tails. twitter.com/nntaleb/status/126

Perhaps Mr Asness can show us empiricists, with the benefit of hindsight, which fund he wants us to pick to get the relative performance.

PS- I have no interest in Asness, not even AQR, but they can't get away w/nonsensical claims abt tail risk.

Ilmanen the bullshitter (& the AQR team) among other things don't seem to get that tail payoff != probability x payoff under fat tails.
You need to include payoffs not part of this, and g(x) is convex (option payoffs by convexity are MUCH MORE FAT TAILED than underlying) twitter.com/nntaleb/status/126

Antti Ilmanen claims tails must be expensive from lottery tickets (but excludes 1987 crash); doesn't get basics: Stat 102 does't cover when assumptions are violated (Gauss-Markov, etc.)
Fails to get Bayes' rule.

Note: while RISK PARITY is ~unique, tail hedges vary hugely. twitter.com/nntaleb/status/126
