1/Today in @bopinion, I talk about the legacy and career of Jim Simons, the founder of Renaissance Technologies, who is stepping down as the hedge fund's

2/Simons' fund beat the market -- consistently, by huge percentages, after fees.

That's an astonishing accomplishment.

https://t.co/uopG6WutzU
3/How did he do it?

Basically, by being relentlessly smarter and better-managed than the competition.

https://t.co/p6ZTd7POfQ
4/So does Simons' success mean markets are inefficient?

Yes and no.

Obviously yes, since Renaissance could (and can) beat the market. But there are a few key caveats...
5/First of all, RenTech's most eye-popping and consistent returns are in its flagship Medallion Fund.

But most investors can't invest in that fund. It doesn't take your money.

https://t.co/sTXUzl09Lc
6/In fact, the Medallion Fund doesn't even take *its own* money. It makes regular profit distributions, so that the fund's total size remains small -- around $10 billion or so.

https://t.co/bhqE71eSdH
7/This means that the Medallion Fund's famous 39% annualized return (after fees) doesn't compound.

If it did, Medallion would be worth far more than all the rest of the hedge funds in the world combined, by now!
8/So a fund like Medallion isn't really comparable to, say, the return of the S&P. One compounds, the other does not.

Why? Because the market inefficiencies Medallion exploits are limited in size. And thus, Medallion's profit opportunities are limited in size.
9/To address this, Renaissance made a bunch of other funds that do different things than Medallion, and whose strategies scale up more. These have done generally well, but they're no Medallion...

https://t.co/ZsXQ4NNUI8
10/Even as Medallion racked up huge gains in 2020, Renaissance's other funds largely tanked.

This shows that consistently beating the market AT SCALE is incredibly hard, even for the smartest and best-managed people on the planet.

https://t.co/oowJd3k8GH
11/That's no knock against Renaissance, of course. They're the best in the biz.

But it does mean that Renaissance's existence doesn't prove that stock markets are inefficient. Indeed it shows us just how not-so-hugely-inefficient they are!

More from Noahtogolpe ๐Ÿ‡

When Republicans started to believe in racial bloc voting - when they stopped believing that nonwhite people could ever be persuaded to vote Republican - they started to see immigration as an invasion.

This explains why immigration is now at the center of partisan conflict.


Of course, the belief in ethnic bloc voting becomes a self-fulfilling prophecy.

When a slight Dem tilt among Hispanics and Asians caused the GOP to turn against them, Hispanics and Asians shifted more toward the Dems. Etc. etc. A self-reinforcing cycle.

Bush's 2006 amnesty attempt, and the 2013 intra-GOP fight over immigration reform, were two moments when the GOP could have turned back to the approach of Reagan, and courted Hispanics and Asians.

But they decided against this, and...here we are.

What will disrupt this bad equilibrium, and save American politics from being an eternal race war?

Either:
A) More white voters will grow disgusted with the GOP approach and defect, or
B) The GOP will find some non-immigration-related issues to attract more Hispanics and Asians.

As long as both parties see elections in terms of racial bloc voting - where the only way to win is to increase turnout among your own racial blocs or suppress turnout by the other party's racial blocs - American politics will not improve, and the country will decline.

Our first panel is about cryptocurrency! We have @matt_levine, @tylercowen, @eiaine, @nirkaissar, and Camilla

Ou: Crypto will be useful for the unbanked.

Cowen: Crypto has to compete against a bunch of other emerging payments technologies. Bitcoin is too inflexible.

Cowen: I'll bet on the payments companies over crypto.

Covid recovery money is going to the oligarchy.

Ottawa and the provinces have put very little on the table to help clean-tech companies directly during Covid 19 while targeting fossil-fuel producers with more than $16 billion in aid.

Coast to coast people have demanded treaties be honored. We demanded climate action, divestment and land back but Canada is not listening. This video shows 10 years of rallies in Waterloo Ontario. City & regional council declared a climate emergency. ๐Ÿšจ

The Bank of China (BOC), SNC-Lavalin and WE Charity were recipients of taxpayer-funded the Covid 19 Canadian Emergency Wage Subsidy (CEWS)

Once upon a time there was a Raja named Uttฤnapฤda born of Svayambhuva Manu,1st man on earth.He had 2 beautiful wives - Suniti & Suruchi & two sons were born of them Dhruva & Uttama respectively.
#talesofkrishna https://t.co/E85MTPkF9W


Now Suniti was the daughter of a tribal chief while Suruchi was the daughter of a rich king. Hence Suruchi was always favored the most by Raja while Suniti was ignored. But while Suniti was gentle & kind hearted by nature Suruchi was venomous inside.
#KrishnaLeela


The story is of a time when ideally the eldest son of the king becomes the heir to the throne. Hence the sinhasan of the Raja belonged to Dhruva.This is why Suruchi who was the 2nd wife nourished poison in her heart for Dhruva as she knew her son will never get the throne.


One day when Dhruva was just 5 years old he went on to sit on his father's lap. Suruchi, the jealous queen, got enraged and shoved him away from Raja as she never wanted Raja to shower Dhruva with his fatherly affection.


Dhruva protested questioning his step mother "why can't i sit on my own father's lap?" A furious Suruchi berated him saying "only God can allow him that privilege. Go ask him"
