There are different ways to estimate it, depending on the factor. Simplest is factors like industry or country exposure where the entries can be 0/1 depending on whether the stock is in that industry/country or not.
A few things that I didn't cover yesterday when I talked about equity factor models (it's a huge area and it's impossible to more than scrape the surface)
A few people in the DMs asking about equity factor models so here's a short explainer.

Let's make it a concrete problem -- you are the risk manager at a big multi-manager hedge fund with ~100 sub-PMs each of whom has a portfolio of 10-50 stocks, long and short.
There are different ways to estimate it, depending on the factor. Simplest is factors like industry or country exposure where the entries can be 0/1 depending on whether the stock is in that industry/country or not.
Now you have a set of linear equations on each day, and you can solve the linear equations to get the vector of factor returns for each day using the normal equation - pic.twitter.com/YwVkUzSM69

It varies depending on the application. The simplest models would have just a few, maybe the market factor plus a couple of others that you care about (think about Fama-French 3 factor or 5 factor model) but it will normally be more.
Yes -- you hear a lot about the well known ones like value, momentum quality etc but there are hundreds of others which are widely known in academia and industry and thousands of proprietary in-house factors.

Tomorrow, January 6th, MAGA chuds, Proud Boys, and white supremacists are planned to descend on Washington D.C. to contest the election. Among them will be NSC-131, a New England based neo-Nazi organization. Let's welcome them by saying hi to one of their members, Eddie Stuart!
Edward Stuart, from Chester, New Hampshire, has been a member of Nationalist Social Club (NSC) since the very beginning and is a staple participant in their actions. He is known in NSC chats as "Carl Jung" and is well connected in the New England Nazi scene.

NSC-131 is a neo-Nazi group that was started in Massachusetts in early 2020 by Chris Hood. You can learn more about NSC and it's members in these threads:
Eddie describes his ideology as "Esoteric Hitlerism" which is an occult form of Nazism that literally worships Adolf Hitler as a god, or, specifically, as an incarnation of the Hindu God Vishnu. Here is Ed holding the RigVeda with some of his occult Nazi pals. Interesting Ed!

Much of this ideological insight was gained from Eddie's Twitter, where he originally used his "Carl Jung" persona and reposts explicit neo-fascist content and racist memes. In one edited picture, Eddie can be seen at an NSC event in late June 2020 holding a Nazi Sonnenrad flag

He now runs a new crew, the National Socialist Club, based on football hooliganism.\u2070\u2070
Some of you already know him.\u2070\u2070
His name is Chris Hood, of Boston, MA. pic.twitter.com/nXAxWugHcu

1/ One year of destroyed economies, social isolation & deep social splits calls for an anniversary ⬇️thread ⬇️ to celebrate the RT-qPCR manuscript by Christian Drosten (@c_drosten) & Victor Corman (@vmcorman), submitted on 21st Jan 2020 to @Eurosurveillanc. #UnbiasedScience
2/ Before this very publication, virologists were neither treated like superstars, nor were they considered icons or half-gods. In 2009, Drosten almost succeeded in installing the false premise virology could supersede holistic medical sciences as discussed in this thread.
3/ Drosten is a virologist. He neither has any background in epidemiology, nor has he ever worked in the civil service. He also doesn’t have a background in public health. Yet he and his colleagues affect our daily lives to the level of whom to meet up or how to flush the toilet.
4/ Before January 2020, Drosten and Corman were common virologists at Charité Berlin, whenever they were not involved in economic implications (https://t.co/UTDwG8U7Du). Other than that, they looked at coronaviruses in dromedary calves in the Middle East or Africa. 😍 #cute
5/ Finally in Jan 2020, the published paper laid the theoretical grounds for the current pandemic, the RT-qPCR mass testing-religion, for which he was awarded his second German Federal Cross of Merit (he received the first one in 2005 for developing the SARS-CoV PCR test).

We finally have the U.S. Citizenship Act Bill Text! I'm going to go through some portions of the bill right now and highlight some of the major changes and improvements that it would make to our immigration system.
Thread:
First the Bill makes a series of promises changes to the way we talk about immigrants and immigration law.
Gone would be the term "alien" and in its place is "noncitizen."
Also gone would be the term "alienage," replaced with "noncitizenship."
Now we get to the "earned path to citizenship" for all undocumented immigrants present in the United States on January 1, 2021.
Under this bill, anyone who satisfies the eligibility criteria for a new "lawful prospective immigrant status" can come out of the shadows.
So, what are the eligibility criteria for becoming a "lawful prospective immigrant status"? Those are in a new INA 245G and include:
- Payment of the appropriate fees
- Continuous presence after January 1, 2021
- Not having certain criminal record (but there's a waiver)
After a person has been in "lawful prospective immigrant status" for at least 5 years, they can apply for a green card, so long as they still pass background checks and have paid back any taxes they are required to do so by law.
However! Some groups don't have to wait 5 years.
