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!

1/People I know on the Right tend to be obsessed with the idea of "crimethink", taboos, and the (supposedly) oppressive, omnipresent enforcement of liberal cultural norms.

Why?

My new theory: A lot of it is guilt.

2/It's true that in some circles - the media, universities, many big corporations - liberal norms *are* enforced to some degree, and the enforcement has probably gotten stronger in recent years.

But I don't think this explains all of the Right's obsession.

3/The stereotype is that people on the Right tend to be more threat-sensitive. That would help explain the perception that liberal norm-enforcers are lurking everywhere, ready to pounce and anathematize anyone who makes a misstep.

But I don't think that's all of it either.

4/And of course, it's always fun - whether you're on the Right or the Left, or playing a video game, or whatever - to style yourself as the brave iconoclastic rebel fighting against the oppressive forces of blah blah blah.

But I don't think this is all of it, either.

5/The reason I think it's more than these things is that even *in private*, people on the Right express their "crimethink" ideas very gingerly and hesitantly.

I get the sense that they're not just afraid of external censure, but have also internalized liberal norms.

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.

1/Here is a thread about climate change that's going to make a lot of people mad.

Basically, America, on its own, has a LOT power to stop climate change than almost anyone admits.

2/China now emits far more CO2 than the U.S. It emits almost as much as Europe and the U.S. combined.

3/In fact, even this huge disparity dramatically understates the degree to which China is in the driver's seat of climate change.

China, being still much poorer than us, has much more room to grow its economy. Hence, the emissions gap will only grow larger.

4/This leads to an uncomfortable but unavoidable fact: The battle to halt climate change will be won or lost in China.

America's power - and thus, the power of American politicians, activists, businesses, etc. - to save the planet from climate catastrophe is very marginal.

5/This is just a fact. But it's an uncomfortable one for a people like Americans who are used to thinking that the world lives or dies at their command.

Thus, I see many Americans desperately trying to preserve the illusion of control with respect to climate change.

1/Today's @bopinion post is about Trump's taxes, and what they show about how America allocates capital.

We appear to have some big problems.

2/Trump has a bunch of businesses that lose money. Our financial system has lent him money to throw into unsuccessful golf courses, hotels, and so

3/A lot of these loans are loans that Trump hasn't even paid back yet, using loopholes in the tax system to avoid paying taxes on those unpaid debts.

Why would creditors give money to a guy who wastes the money on bad businesses and doesn't even pay them back?

4/One seemingly obvious answer is that capital is just really cheap these days. Companies are able to borrow more easily than at any time in the last few decades.

5/But this presents us with a mystery.

Why hasn't an abundance of cheap capital caused the return on financial capital to fall? Interest rates are low, but stock returns have held up strongly.

Today's @bopinion post is a review of the excellent new book "The Gift of Global Talent: How Migration Shapes Business, Economy & Society", by

This is an excellent, short, highly readable, very important book. Every business executive and politician should have a copy.

Why are skilled immigrants so good, and so important?

Because they're the backbone of high-value industries where the U.S. has a dominant position.

If we don't bring skilled immigrants to the United States, high-value industries will migrate to other countries, and America will lose industrial dominance and be a poorer country.

Contrary to popular belief, skilled immigrants - including H-1b workers - RAISE wages for native-born skilled workers.

Why?

Because downward wage pressure from competition is more than canceled out by the upward wage pressure from CLUSTERING.

Trevor Chinn has funded various Labour MPs over the years including Owen Smith, Tony Blair, Joan Ryan, Ruth Smeeth, Tom Watson, Ian Austin, Rachel Reeves, Lisa Nandy, David Lammy, Liz Kendall, Dan Jarvis, Tristram Hunt, Jack Dromey, Liam Byrne. #LabourLeaks #StarmerOut #BICOM

Chinn has funded BOTH Labour Friends of Israel and Conservative Friends of Israel . The multi-millionaire pro-Israel lobbyist donated $62,000 to Keir Starmer to win the UK Labour Party’s leadership election. April 2020 #LabourLeaks #StarmerOut #BICOM

Tom Watson, former BICOM staffer Ruth Smeeth and Labour Friends of Israel’s then chair Joan Ryan.

All three played key roles in promoting the smear campaign that Corbyn’s Labour Party was a hotbed of anti-Semitism. BICOM is important to Starmer. #LabourLeaks #Defence #Brexit

Hoping to remove Corbyn as leader. Chinn funded Corbyn’s rival in the resultant leadership election, Owen Smith.

Smith took donations for his campaign from Chinn totaling $33,000, the register shows. #BICOM #LabourLeaks #StarmerOut

The BICOM group arranges for influential figures to take trips to Israel. These have included trips to the Herzliya conference, a major “security” event at which powerful business and political figures discuss how to reinforce Israeli occupation and apartheid. #StarmerOut #BICOM

I am bemused by those who demand that we repay the UK government’s debt. It makes me wonder, do they know what it is? And how do they think it can be repaid? And do they appreciate the consequences? A thread is coming on......bear with me, because I think you need to know this.

First, what is the UK government’s debt? I’ve immersed myself in this issue and can confidently say the Office for National Statistics’s figures are wrong, most especially because they claim that the UK government is in debt by owing money to itself. That’s not possible.

Whatever the Office for National Statistics like to claim, money you owe yourself is not debt, and so quantitative easing cancels about £800 billion of UK national debt right now. There are other mistakes in their numbers, but I’ll just stick with this one for the moment.

So, if the ONS claim the national debt is around £2.1 trillion at present, it isn’t. Allowing for the UK government owning around £800 billion of its own debt the figure reduces to maybe £1.3 trillion, give or take a bit. But that, I hasten to add, is not the end of the story.

It’s important to understand that the ONS includes some things few would think of as debt in their figures. For example, around £200 billion (£0.2 trillion) of National Savings balances are included in the national debt. Whoever knew Premium Bond holders were such a burden?

I don't normally do threads like this but I did want to provide some deeper thoughts on the below and why having a video game based on a real world war crime from the same people that received CIA funding isn't the best idea.

This will go pretty in depth FYI.

I couldn't possibly guess why Six Days in Fallujah is being revived at a time when US army recruitment is at an all time low.

This reboot is from the same people that worked with the FBI and CIA on training systems and is basing its game on excusing US war crimes. pic.twitter.com/5H8vVqKh9s
— Daniel Ahmad (@ZhugeEX) February 11, 2021

The core reason why I'm doing this thread is because:

1. It's clear the developers are marketing the game a certain way.

2. This is based on something that actually happened, a war crime no less. I don't have issues with shooter games in general ofc.

Firstly, It's important to acknowledge that the Iraq war was an illegal war, based on lies, a desire for regime change and control of resources in the region.

These were lies that people believed and still believe to this day.

It's also important to mention that the action taken by these aggressors is the reason there was a battle in Fallujah in the first place. People became resistance fighters because they were left with nothing but death and destruction all around them after the illegal invasion.

This is where one of the first red flags comes up.

The game is very much from an American point of view, as shown in the description.

When it mentions Iraqi civilians, it doesn't talk about them as victims, but mentions them as being pro US, fighting alongside them.

Talking with Georgie about the horrible crime committed against Brittany Higgins.

I hope Brittany finds some justice, somehow.

Here's the thing: nothing that matters will change.

A thread:

Two side notes:
* Content warning for trauma and sexual assault
* I initially drafted this and was going to delete it because it's too cynical and very bleak, but it's also the truth and Georgie asked me to be brave and post it.

A Royal Commission has changed nothing.
Paris Street's revelation about St Kevin's changed nothing.
Grace Tame's bravery has changed nothing.
The Pell case has changed nothing.
The Wilson case has changed nothing.
The Redress Scheme has changed nothing.

Georgie burning two careers to jail a serial child rapist has changed nothing.
The National Apology has changed nothing.
The hundreds, if not thousands, of people who report sexual assaults each year have changed nothing.

Because the rules don't apply to the people at the top.

If you're at the top, it doesn't really matter if you're a politician, a political staffer, a journalist, a senior police officer, an ADF officer, a bishop, a business tycoon, or anything else.
If you're in the club, you're in the club.

RANI GAIDINLIU:THE LESSER KNOWN FREEDOM FIGHTER

Rani Gaidinliu joined the freedom struggle at 13 &was sentenced to life imprisonment at 16."We r free people—the White should not rule over us.”Thus calling out to her Zeliangrong tribesmen was the voice of 13yr-old Rani Gaidinliu.

She joined the freedom struggle in the present-day Northeast India. Today, her struggle is lost in history as most of her countrymen wouldn’t even have heard her name. B'coz our history textbooks tell us that only Mahatma Gandhi &Pandit Nehru got India its Independence.

At 16 yrs of age, this valiant girl was sentenced to life imprisonment for leading a movement to drive out the colonial rulers from Manipur and Nagaland. Nevertheless, she was released in 1947 after India’s independence and was given the title ,"Rani of Nagas".

EARLY LIFE AND HERAKA MOVEMENT

Gaidinliu belonged to the Rongmei clan of the Zeliangrong tribe in the Tamenglong district of western Manipur. Born on January 26, 1915, she was fifth among eight children.

Her native village was Nungkao, which is present day Tamenglong distt. Brought up in a specially backward region,she couldn't receive any formal education. However,this didn't stop her from joining the freedom struggle. At the age of 10 she came under the influence of her cousin.

Manipulation Sign:

If you are compromising too much, there is a chance that you are getting manipulated.

Why are you the one that's always compromising?

How come the other person always gets their way?

Be more curious.

If something seems off, stick up for yourself.

'Wait, you sure I am being manipulated?'

I have no clue, that is only something that you can decide for yourself.

'Dang is there anything I need to look out for?'

Plenty..

But let me give you a few things to look out for.

👇

I see manipulation as skillfully controlling someone's behavior for egotistical or unethical purposes.

'How come people don't leave when it's happening to them?'

Because most people have 0 clue that they are being manipulated.

1. Guilt Trip

You ever made a mistake around someone, only for them to hold it over your head?

The will always bring up the mistake when you 2 are not seeing eye to eye.

These people will use that mistake as leverage to get what they want from you in the future.

Look out.

2. The Rationalizer

This person will commit the worst acts & find a way to rationalize it.

Example: cheaters when they get caught.

They have every excuse in the book for why they did it.

Heck, they are so good at rationalizing, they will make it seem like your fault.

❤✈️🌎 2 years ago today @JamesIvings and I sold all our belongings and left the UK to travel for a year. We've never been happier and we have no plans to ever return there 🙂

Thread 👇

Since then we've started a remote web dev company @SquarecatWebDev and been lucky enough to have completed several freelance projects 💻 that have kept us on the road.

In the last few months we've become a huge part of this amazing new Maker community and have found so many new friends from @makerskitchen, @women_make_ and several others! 🥰

We love travelling together (even if I'm only a glorified laptop watcher 😒) but we're both much happier being able to share our ideas outside of our own little bubble and our products have benefitted too!

Here's to another year of nomading with my favourite person and to the Maker community continuing to grow with our help! Maybe one day we'll all get to meet each other ✌️ 💛

THE BATTLE OF SARAIGHAT (1671)

Lachit Borphukan's humiliation of Aurangzeb.

The battle of Saraighat was a naval engagement fought on the Brahmaputra river near Saraighat between the M0ghul empire and Ahom kingdom in 1671.

Guts, resolve and glory!

(Elaborate thread)

Koch was a state situated between the dominions of M0ghuls and Ahoms. For Ahoms, it was a buffer state for keeping M0ghul territorial expansions at bay.(1)

Times changed when the ruler of the Koch kingdom, Nara Narayana passed away in 1587 resulting in Koch being divided into 2. Western Koch was ruled by his son Lakshmi Narayan and the eastern Koch by his nephew, Raghudev.(2)

Lakshmi Narayan formed an alliance with M0ghuls after which he attacked Parikshit, son of Raghudev, in 1602. Parikshit Narayan was defeated while his brother Bali Narayan took refuge in the Ahom Kingdom.(3)

The M0ghuls used it as a pretext to invade Ahom kingdom. The first battle between them took place in 1615 leading to a series of engagements in which both sides had their shares of ups and downs resulting in a stalemate.(4)
