"if you want to auto-delever in a way that's going to minimize your future risk of equity shortfalls, then you have to focus on the accounts that are closest to insolvency, and that is going to be the most highly leveraged accounts."
@ciamac from @columbia_biz explores the optimal way to ADL on perps exchanges.
ciamac moallemi retweeted
Auto-deleveraging is essential, and the industry standard may be broken.
@ciamac of @Columbia_Biz uses Hyperliquid’s data from October 10 to show how current ADL rules can be gamed and proposes a model with nearly 3x the risk reduction.
1:27 Why traders hate ADL
2:07 October 10 took $2B on Hyperliquid
3:16 Every exchange copy-pasted BitMEX's rule
3:37 How to game the current system
5:07 Why leverage is the right ADL priority
8:23 How leverage-based ADL can't be gamed
10:01 October 10 with 3x the protection

@ciamac @Columbia_Biz explains auto-deleveraging and offers an alternative. Donghwa Shin @kenanflagler provides comments:

Under stress, derivatives protocols have to make hard decisions in real time:
→ How options decay
→ How leverage is reduced
→ How ADL is triggered
→ How losses are allocated
→ How solvency is restored

I am sad to hear of the passing of Dimitri Bertsekas. This one hurts.
Dimitri had a big effect on my career, from inspiring research topics to writing one of my tenure letters.
A long thread on memories of Bertsekas and some of his works that influenced me the most.

Sharif is the #1 university in Iran. Over the last 25 years, it has been in the top 3 destinations of top Olympiad medalists.
What do the smartest kids in the world do when they grow up?
I did the largest study of ~18,000 International Olympiad medalists (IMO, IOI and IPhO) over the last 25yrs, arguably the sharpest analytical minds of the world in high school, to see where they ended up and traced ~50% of them.
Founders of ~20 unicorns and ~7 decacorns and ~10 billionaires: OpenAI, Cursor, Stripe, Databricks, Perplexity, Ethereum, Cognition, Hyperliquid, Fireworks, Modal, Quora, Parallel, Cartesia, Wispr
Most kids went to MIT, a whopping 12% of them, followed by Cambridge (7%) and Sharif (3%)!
The career paths they chose (of those who graduated) were:
— 36% Academia (professors)
— 26% Other
— 22% in Software / Tech
— 12% in Quant / Finance
— 5% Founders!
The biggest employer was Google, by far, at 6%.
Others interesting tidbits were:
— 47 of them work at Jane Street (#3)
— 38 at OpenAI (#5)
— 15 at Anthropic
— 8 at Cognition
— 6 at Isomorphic Labs
Olympiaders were 1500x more likely to be billionaires and 4000x more likely to be unicorn founders than the average person!

Sharif University of Technology (founded as Arya Mehr University in 1966) is an icon of modernization and progress in Iran. Its alumni include the first woman to win the Field Medal in Mathematics, Maryam Mirzakhani. It has been a national symbol of achievement, gaining international recognition for the quality of its graduates, large number who have been admitted into the very best engineering programs in the West. The aim of this kind of wonton destruction could only be the nation of Iran itself.

Oh man, who knows where this will lead, but at the least we may get to read some VERY interesting emails from and to Columbia's oligarchic trustees and admins: Court Finds Columbia May Have Acted as Government’s Instrument to Suppress Palestinian Advocacy cair-ny.org/news/3/19/26-bre…

🚨 NEW: Over the past year, Columbia University has played a direct role in the arrests and targeting of its international students by federal immigration agents, in violation of the university's own stated policies and protocols.
What began last March has continued since — Mahmoud Khalil, Mohsen Mahdawi, Ranjani Srinivasan, Yunseo Chung, Elmina Aghayeva...

Told this to the New York Times today and will not stop saying it.
Iranian Americans who oppose their homeland being bombed deserve to be heard right now.
Bombing elementary schools and killing schoolgirls doesn’t bring freedom and democracy to anyone.

This ruling against Columbia University is a victory for free speech, and all the values that underlie the academy.
BREAKING: In a major victory for pro-Palestine student protesters at Columbia University, a judge in New York on Friday dismissed the university's findings of several disciplinary violations against 22 students who had been arrested over the occupation of Hamilton Hall in April 2024.
The protesters had occupied the Columbia building and renamed it Hind's Hall, in honor of Hind Rajab, a Palestinian child who had been killed by Israel earlier that year.
New York Supreme Court judge Gerald Lebovits noted that Columbia's internal panel's determinations that the student protesters committed most of the charged disciplinary violations are "arbitrary and capricious".
"...the evidence before the panel still did not show by a preponderance that petitioners committed disciplinary violations other than being in Hamilton Hall during the 22 hours that it was occupied," the judge noted.
Here's the operative part of the court order below.
