Ken Griffin's ultimate rule for survival is brutally simple when asked how Citadel survived a near-death experience in 2008 to become a $60 billion empire - he dropped pure reality: "we lost 50% of our capital and our flagship fund was down $8 billion - that's when you realize...

Everything citadel is doing now, Jim Simons at RenTec did it earlier, bigger, and better. In money managers of all and any stripe - Jim is at the top, bar none. Rest in peace.

The Fed bailing him out multiple times helped even more

Yeah, that's why whenever there's some hiccup, the market fucking breaks, and no one can execute. Because they are a dogshit market maker. Taking some risk would be the whole point of being a market maker!

Survival in markets is mostly a liquidity discipline, not an IQ contest. The firms that last treat leverage as a temporary tool and cash as permanent optionality. Stress events punish crowded books first, then weak funding, then bad marks.

Survival of the fittest! Ken's playbook is a wild ride. Sometimes you gotta hit rock bottom to build a skyscraper.

Take away my money, strip me of all of these, but leave me my slaves, and in two or three years I’ll have everything again

“bookmark and watch him break down the reality of risk” absolutely going to do that!

Harry Markowitz, the Nobel laureate who invented modern portfolio theory: "Every fund from Bridgewater to Citadel runs on one equation I wrote as a 25-year-old grad student. Wall Street pays quants $500K to use it. It's free." the thread above teaches you to build a portfolio the real way, with the mathematics of capital allocation. every line of it traces back to one paper markowitz wrote in 1952. before him, "don't put all your eggs in one basket" was folklore. he turned it into algebra. he proved a portfolio's risk isn't the average of its parts, it's driven by how the parts move together, the covariance. combine assets that don't move in lockstep and you cut risk without giving up return. that is the closest thing to a free lunch in all of finance, and he wrote the exact equation for how much of it you get. that single insight, mean-variance optimization, is the engine under every serious fund on earth. renaissance, bridgewater, citadel, your pension, all of them size risk with markowitz's math. he published it in 1952, won the nobel in 1990, and it sits in every textbook and this free lecture. same story i keep telling: the math that runs the trillion-dollar machine has been public and free for seventy years. here is the part markowitz himself warned about. the equation is only as good as the numbers you feed it, your estimates of return and covariance. feed it garbage and the "optimal" portfolio it hands back is confidently, precisely wrong, and it detonates in the exact crisis it was built to survive. the optimizer is free. estimating the future honestly, and knowing when to distrust your own inputs, is the entire job.
