Transcripts

Quants short for quantitative.

They're a special type of nerd that has come to invade

our beautiful world of finance.

I have always imagined the classic Wall Street

trader to be your typical, handsome

fella who knows how to handle the cross

stick and a non-disclosure agreement.

But lately, it's come to my attention

that the real

wolves of Wall Street are not charismatic Buck Mason bros,

but instead this army of reclusive dweebs

who are pulling in fat salaries and wrestling with complex

mathematical algorithms

that would make my old buddies on the trading floor

commit seppuku inside of a Just Salad.

Learning about quants

folks has truly turned my world upside down.

So put on your sweatpants, pick up your calculators,

and leave those boat shoes in the mudroom.

We're about to learn.

How. Today, quantitative strategies are incorporated

across the financial industry, But when people say quant,

they're probably referring to the most famous types: traders

and researchers at fancy hedge

funds and investment firms like Jane Street, Citadel

and Two Sigma.

These quants use financial models to try to pin down the future

values of securities, commodities, currencies

and all types of financial products.

And it's a job usually given to young people fresh out of top

tier schools

and seasoned from years of math competitions and Adderall.

and it's these people who generate a lot of moolah

and a lot of buzz.

what exactly is a quant?

what's a quant? the pinnacle of finance?

They get paid a lot.

like $5,000.

$250 an hour

$500k to $700k total comp

how do I become a quant?

That's my quant.

Your what? My quantitative.

My math specialist. Look at him.

You notice anything different about him?

So who exactly are the people behind the monitors?

I spoke to some Smarties who have been inside the world

of quant in various ways,

some of whom prefer to stay anonymous,

but none of whom were afraid to give it to Papa

Journalism fast and straight.

What do quants actually do?

Right...umm...

Code.

And do maths.

Well, great.

This has been a lovely interview

A lot of math

and a lot of computer science.

As a quant-

a signal in the market is just

anything that can happen

that we think is predictive

of something else.

The signals that quants excel at

are things that your average

banker would never

in a million years notice.

Things that are buried

into the math.

Stuff you can only find with

big amounts of data analysis

and-

machine learning.

There’s huge amounts

of research

on being able to predict

the weather in like Nebraska

five days from now

because if we

figure out that it’s gonna be

three degrees hotter

than it actually

like-

the weather forecast predicts

then we know that a pipeline

that’s carrying oil

from the Northeast to Texas

going through Nebraska

might cost an extra

ten microcents

per liter

so we can

you know, adjust those markets

ever so slightly.

I obviously had no idea what he was talking about.

So to learn

more about how the hell

bookworm freaks like him ended up in finance, I had to go

back to the beginning, which for quants means the Renaissance

technologies.

Renaissance technologies.

leader of the quant trading movement and founded in 1982.

Renaissance Technologies is a trading firm

who embraced algorithms years

before everything else in the world embraced algorithms.

Renaissance’s king dork

Was Jim Simons

one of the few early mathematicians

who brought their talents from the halls of academia

to Wall Street in the sixties and seventies.

Yeah so he’s

a pioneer. I wouldn’t say THE pioneer,

the only pioneer, he’s among the pioneers

of this quantitative push

Gregory Zuckerman is an investigative reporter

at the Wall Street Journal and author of The Man

Who Solved the Market, a Biography of Jim Simons.

If he had only done mathematics

He’d be worthy of a book and all kinds of recognition.

And he gave it all up to go into trading and investing.

And his firm, it’s called Renaissance Technologies, and the key hedge fund, Medallion,

is the greatest moneymaking entity Wall Street’s ever seen.

Their average returns are 66% a year over many, many deacdes.

For context averaging 66% in returns is literally better

than any investor you've ever heard of.

Warren Buffett.

Ray Dalio.

Wilmer Guffins. George Soros.

Literally, none of these guys even came close to that number.

Not even the one I made up.

But why then, isn't Slim Jim as big of a name as these guys?

He was very secretive. He didn’t want the acclaim,

If anything, he avoided it.

It was a really difficult project to write this book.

People weren’t allowed to talk to me. They’re not allowed to talk in general.

They have these really thick NDAs.

And it turns out the secrecy that defined Renaissance is actually quite characteristic of the quant industry in general.

They’re worried someone’s gonna pick up on some of their secrets.

They don’t let people talk, and they sue you if you go to another firm.

So if you’re, you know

going on yapping about

you know, this

wacky new trading strategy

you found

they’re gonna go implement it

at their firm

and you’re gonna lose

all your edge

because-

you can’t have edge

in the market

when everyone knows

what you know

all of the value

is to be had

in being the only one that

knows what’s going on

in that specific scenario.

fortunately for these firms under the radar

is how their mathletes like to operate.

These are academics, these are kinda quirky people.

They’re not people that bask in the limelight. They run from the limelight.

So I enjoyed solving maths as a kid. I used to enjoy the process of

being able to apply some solution and get some exact answer and know it was correct.

I enjoyed having to think about-- kind of work out the puzzle.

And I think after a while you can kind of get addicted to that feeling of trying to solve these problems.

You’re not really

motivated as much

by money

even though money is certainly

a part of it.

These are people

who just wanna solve

basically interesting problems

but I think it’s a completely

different motivator

in some ways than other parts

of the

banking world.

I mean, I'm

sure the salary doesn't doesn't doesn't hurt either, I imagine.

Right, right, right

But even if these basement lurking money droids

don't seek the limelight,

the limelight has certainly found them.

By 2017,

quantitative funds accounted for over a quarter of all U.S.

stock market trading and unlike

Like the Ivy League of a Cappella Wars of 2013.

I'm not the first one to report on this.

Quants becoming a central player in finance.

is old news.

But as the amount of the market

that we're putting into the hands

of computers continues to grow, and as computers

become more powerful,

fear around algorithmic doomsday scenarios grows as well.

Today, parts of these advanced programs are so-called

black boxes, meaning we don't always know

why algorithms recommend certain trades.

also people are worried about fun stuff like AI

going off the rails and making rogue buy and sell decisions.

then there's stuff that's already happened.

For example, in August 27,

billions of dollars

evaporated from the largest hedge funds after an algorithmic

fire sale

or maybe you look at what happened in 2010

when an automated trading software

rapidly sold a shit ton of futures contracts

to do with the S&P 500 and erased $1 trillion in market value

I remember that day well before dawn.

I was lying in bed next to my second wife,

my eyes wide open, peering over a field of frosted grass

outside of our window.

And I said, Honey, I don't know what it is,

but I feel like $1 trillion in market value

will be erased from the S&P 500 today.

And then she said, Hush, Dan,

I'm dreaming of a man who can make me climax.

You know, we stayed together for three years after that,

but in that moment I knew the relationship was over.

It’s sort of like the boogeyman today where everybody,

if you can’t figure out why the market moves, then it’s gotta be the quants.

That’s sort of like the instinctive explanation.

And I think that’s a little bit unfair.

I don’t think they’re foolproof.

I don’t think they’re necessarily so much better than everybody else.

But we’ve had panics throughout history

in financial markets, so...

we’ll have some computer-oriented panics

in the future, but we’ve had em in the past as well.

So then can I ask, what's your read on the quant industry today?

Have most hedge funds embraced

quantitative trading as a strategy,

So, there are two things when it comes to investing. There’s the

idea of what to buy or sell.

and there’s how to buy or sell, what we call execution.

When it comes to execution, pretty much everybody has embraced quantitative financing.

Where to allocate, how to break up the trade so it doesn’t move prices around...

When it comes to the idea-- the genesis, the thesis of what to buy--

not everyone has embraced it. Not everyone should embrace it.

Even the Renaissance people believe in man plus machine kinda thing.

Or more machine plus man.

So what do quants actually do?

Well, they do a more precise academic version of what

we all do in this green flat Amex card shaped world of finance.

They speculate.

They gamble.

try as hard as they can to turn uncertainties into certainties

all in the glorious name of get in the bag.

These robots just do it with higher IQ, better degrees

and more advanced tools than the rest of us

quants, believe it or not.

your people, too.

And I'm sorry for ever judging you

for good work.

I'm Dan Toomey.

But surely this world of quants wasn't

beyond the grasp of a man like myself.

So I had one of my anon quants engage in a roleplaying exercise

where I pretended to be them

and they pretended to be a higher

up at an elite quant trading firm.

Somehow this wasn't sexual.

Hey Dan

ummm

the ultima for uhh

PLTRs a little bit

lagging behind the uhh

the polynomial fit we

ran the GBU on

do you have any idea of how

we could you know

better implement like a

decay skewed Black Scholes

on this or something?

I think there’s

some sort of like

Stochastic drift

I’m not catching in my model.

Yeah I can look at that.
