大学の寮でヘッジファンド立ち上げました。映画と違って、体験は楽しくも魅力的でもありませんでした。訴訟、セクハラ、FBI、窃盗、差別など、色々なことが起こったんですけど、本当に成長できました。更に面白い物語もあろよ〜. (本を書いたら読んでくださいねー☺️). 先月、利益の記録を破りました🔥.

Here's a hard truth that quant firms can't say out loud: According to multiple sources from Tier 1 quant/HFT/prop shops, the number one indicator of success as a quant trader is the university they attended. for undergrad. 🧵.

Sometimes I'll meet a quant hedge fund that I'm 100% certain will fail. It's not because of the founders (many young and unique folks have succeeded in the past). But it's almost always because there's a market microstructural detail that they're unaware of, that makes their.

“How do you break into HFT or quant trading?” You’re not gonna like my answer but here goes nothing: There’s only ~20 “large” HFT firms out there that employ over 500 people. Most of these employees don’t do HFT, but serve in supporting roles or on non-HFT teams. 🧵.
