🔮 The Future of Quantitative Finance
Dimitri discusses the future of quantitative finance in response to a subscriber's question. He highlights the evolution of educational requirements for data scientists and the potential trajectory for quants. Dimitri expresses skepticism about the devaluation of data science as a field, noting the shift from requiring a master's degree to accepting undergraduate degrees. He criticizes the industry's dilution of what constitutes a data scientist, suggesting that the role has been reduced to basic data analysis. Dimitri also touches on the maturity of quantitative finance compared to data science, suggesting that quant finance has already undergone a cycle of devaluation and is now more structured.
📉 The Dichotomy of Quantitative Roles
In paragraph two, Dimitri delves into the bifurcation of quantitative roles within the finance industry. He describes how firms are separating junior and senior quantitative positions, with juniors handling data analytics and seniors focusing on complex model development. Dimitri argues that while junior roles might be filled by undergraduates, the senior roles increasingly require PhDs due to the complexity and rigor required. He also discusses the reluctance of firms to invest in extensive training programs for undergraduates, preferring to hire those with advanced degrees who are already well-prepared.
📈 The Role of Data Science in Finance
Paragraph three addresses the role of data science within the broader context of finance and machine learning. Dimitri views data science as a subset of machine learning and AI, which in turn are subsets of statistics. He criticizes the data science community for being insular and resistant to traditional statistical methods. Dimitri also discusses the cultural divide between data scientists and statisticians, suggesting that data scientists often lack a deep understanding of the models they create. He emphasizes the importance of model robustness and reliability in finance, contrasting the data science approach of rapid model development with the more cautious and rigorous approach required in quantitative finance.
🏦 The Economic Reality of Hiring in Quantitative Finance
In the final paragraph, Dimitri reflects on the economic considerations of hiring within quantitative finance. He notes that banks and firms are often looking to hire undergraduates to save on the costs associated with higher degrees. However, he argues that this approach rarely results in high-quality models due to the complexity of the work. Dimitri suggests that the industry may be moving towards a segmentation where more technical roles require master's degrees, while less technical roles might suffice with undergraduate degrees. He concludes by reiterating the need for the data science community to mature and integrate more traditional statistical methods into its practices.

hey YouTube It's Dimitri and today we're
going to answer a subscriber's questions
specifically on the future of
quantitative Finance here so I was going
to read this whole thing but I don't
want to bore you too much essentially
what the question is here which I'll put
on the screen
um is they've been talking about you
know what do you think is going to
happen to the future of quantitative
Finance uh you know you speak extremely
difficult to become a data scientist and
there used to be this minimum required
requirement to have a master's degree
and then it's kind of evolved in change
and now it's basically like you can get
in with an undergrad
uh but you know they're kind of
wondering what's going to happen with
Quant finance and essentially like
they've seen you know kind of mixed
perspectives on you know do you need a
masters do you not need a master's in
Quant Finance in the future where do I
think this is kind of going to go
um and they understand you know that you
know for data scientists a lot of
companies don't know what they really
are and so that kind of muddies the
water a little bit
um so basically what are the minimum
requirements here of a Quant in the
future
these videos you guys ask the tough
questions uh honestly it's because data
science I think is a massive joke
um I'm gonna find so many people
watching this but that's okay
um the longer I study data science the
more data scientists I work with uh the
more I realize it's like everybody just
wants a shortcut and everybody wants the
get rich quick scheme and I don't blame
actual true data scientists per se
I'm going to put a little pin in that
for now because there's really yeah it's
just been degraded down to nothingness
like data analytics is the same as data
science now uh using Excel and GBA
apparently is now data science and
everybody I talked to as a data
scientist like even people that have
degrees that aren't even related like oh
I've taken a day of the science course
as if like they're gonna like you know
stamp their resume or stamp their
graduate degree like their data
scientist because they took a course
um I mean it's laughable it's like me
taking you know English 401 or something
and then being like I'm an English
expert I'm going to write a bunch of
books and novels and you know stories
and fairy tales and I'm excellent of
course I'm not I'm terrible at these
sorts of things
um but no data science and machine
learning as a whole is one of those
weird Fields now or if you look at a lot
of the job descriptions so I've been in
this industry a bit here in Quant
Finance
um I sit on fintech now it's where I'm
working currently I advise and discuss
and chat with people in D5 fintech
Finance traditional Finance it's Quant
Finance Banks investment firms like I
rub shoulders a lot of different people
even in industries that are analytical
driven that have full staffed data
science teams that are highly rigorous
but the reality is is that now people
have kind of gotten away from data
science because when it started being a
data scientist with somebody who could
actually build models and they took it
seriously as an actual science
unfortunately though what's ended up
happening is that
it's degraded down into like I mentioned
people using Excel and you know coding
things now in Python and R so simply
that they have no idea what's even going
on they can't even address the issues
themselves and so uh all these firms now
all these big Tech firms those other
companies have started now just changing
titles like you're now a machine
learning engineer or you're I don't know
a machine learning scientist or I work
in AI uh again they're technically
different things but the industry is now
coping with the struggle of you've
degraded data science what it was
originally down to like lowly data work
and there's nothing wrong with that but
to do General analytical data
calculations and things like taking
averages
or just haphazardly fitting something
like a model to you know a bunch of dots
on the screen it doesn't really matter
you don't need a rocket scientist or a
Quant to do this or someone super
rigorously educated and trained with a
master's degree from top university or
even a PhD and so you have to kind of
weed through this this is the one piece
of this this is the
you know this is what's happening to
data science as a whole uh Quant Finance
has got already gone through this so
Quant Finance is much more mature uh in
the life cycle of career development
education and things and it is
struggling as well here which I perhaps
make another video on in the future
um but it went through that phase where
it was like being a Quant was like top
paying amazing stellar and then you know
people couldn't pay you enough people
couldn't find you if you had a master's
in Quant Finance uh before like 2007
2008 it was the dream time to be a Quant
so what ended up happening here is that
financial markets blew up 2007 2008 uh
way too many Master's programs have been
created over the years and again the
quality and standard of quants has been
degraded down to very very minimalist
portions but I think more importantly
here we have had many many banks and
firms so quantitative finances much more
structured and defined uh so Banks and
firms that need people to build models
to to do things where you're either
right or wrong and if you're wrong you
lose a lot more money it's easier to see
when you're right and wrong these sort
of firms they've sampled and tried doing
the undergrad path and there are still
some which I won't name here firms and
banks that are doing it and most firms
that have attempted and tried this have
failed absolutely miserably the ones
that are still continuing to do it here
in 2023 they've actually split these
into two different jobs and you have
like a junior quantitative person in a
senior quantitative person and
realistically what's happening is Junior
quantitative people are doing like the
data scientists are doing they're just
doing data analytics and simple
things uh and then what's ended up
happening is they have the actual quants
which now they're bringing in a lot of
them are just phds and they're having
the phds actually do the model fitting
and the theoretical part of actually
putting all the pieces together making
sure it's correct and it's going to work
um so they can say and I've seen many of
them standing on their uh you know Ivory
Towers saying oh we're equal opportunity
employers and we're trying to bring in
undergrads here but Quant Finance is one
of those areas where it's like they just
can't boil it down you have to have so
many skills to do it correctly that
there's no way I don't think to get
under the Masters minimum here now you
could create massive training programs
and I've seen firms do this where
they've brought in undergrads and then
they have all this mandatory Education
and Training and it's like hundreds or
thousands of hours of training to get
these undergrads to that point but again
it's an investment piece here do firms
really want to do this some do some
don't 99.9 of all Quant Firearms don't
want to do that because to hire a bunch
of training and educational people which
is just expensive and often it's not
worth the effort when you can just go
out and find Master's students now data
science as a whole let's just break this
down more specifically it's kind of like
a weird I don't know it's like the
little brother of Quant Finance in many
ways but a lot more General so iview
data science as just like the whole
picture of your model Developers for a
wide area but unfortunately you
realistically only use tools in the
machine learning space uh that's kind of
what's happened here because if you
start backing out the reality of this
when firms hire such as myself in the
quantitative Finance space I view data
science as just a subset in machine
learning and AI as a subset
AI is kind of on the border because you
can do automation with that but the
model development portions of these as a
subset of Statistics so and then data
scientists get up in arms and machine
learning people and they're yelling and
screaming oh you don't know it's
completely different uh you're still
using logistic regression you're still
using OLS as much as you cry and
complain and hate linearity and you know
oh what about these non-linear cases
here you know you can do all that
actually with linear regression again
I'm not going to go into that doing data
Transformations and variable
Transformations going to the models but
what ends up happening is that they're
so specialized into only one area it's
like you kind of have a specialty but
you only can use a couple tools because
if you use all the tools you're not
really a data scientist or machine
learning expert you're just a
statistician or a Quant in the finance
space but more or less I figure like
data science was going to take a more
well-rounded role which they have not
the community itself I think is quite
um quite toxic to be quite honest with
you like people I've met and ran into it
ends up in this weird weird nuanced
space where it's like they don't want to
use any tools except for those in their
space and there's this like I'm on
LinkedIn the last few weeks you're
scrolling and it's like there's so many
just garbage pieces of people
complaining about how horrible
statistics are how horrible econometrics
are uh there's even people in Quant
Finance like this which I don't have
much respect for in this aspect though
they have other great contributions as
well the industry
um but it's like why would you do
anything with half the tools like I
wouldn't go fix my car and say I'm only
going to use this half the toolbox
because the other half isn't good and
this applies you into the stats for them
as well there are many people that are
pro and anti machine learning on the
stat side I think though it is starkly
different that data science machine
learning is very toxic as a culture in a
community it's very anti-stats where on
the stats I think a lot of us are just
more or less like
we're leery like why are you like you're
doing this new approach and often I put
it in air quotes new approach which is
typically a traditional approach been
relabeled and then it just takes us time
to figure out what you're trying to do
uh and then a lot of it's just
nonsensical so the data science approach
I am a hundred percent against for most
problem solving there are cases where
you could use it but the data science
approach being I have data I need
maximum accuracy Do or Die let's get
maximum accuracy and that's what ends up
happening and they even have these so
someone who actually managed teams and
runs people and worries about
profitability and things that have
nothing to do with the model development
process
um on the management side of this right
I don't want to have to have models blow
up because in Quant Finance again here
it's going to act my finance background
the issue with this is I can't afford to
have a model just blow up and just not
have a model
like this might be okay in the investing
side because again in investing you have
so many dollars and if you have a model
blow up and you just want to close the
position so you're like ah the model is
not really working anymore we didn't
really lose too much but it's not
working you can just close that and just
hold on to cash now on the banking in
the sell side of this uh we have to make
loans to people that's how we make money
and that's how we employ thousands and
thousands and thousands of people at
these massive Banks and even fintech uh
D5 and crypto firms as well a lot of
these that are not focused on the buy
side the investing piece of it but are
on the sell side you have to have a
fraud detection model to detect fraud
you have to have all these operational
models to determine optimizations of
different sorts of problems like
portfolio positions for example perhaps
more on the investing side and when
these things blow up you have to have
something there the problem with the
data science approach is that you know
you just
slap something together to hurry to get
to a solution and you don't care if it
blows up or not because you're just
going to redevelop a new model and
there's always this idea that keeps
getting pushed so it's not actually
implemented in practice by many firms
which is that you're going to automate
this whole process completely so now you
take machine learning and Ai and you put
them together and what people oddly
don't understand is you can take
statistics and Ai and automate
statistics as well that's what stepwise
regression or stepwise uh variable
selection is so stepwise forward and
backward selection you could literally
just automate it and have it go out and
magically pick variables throw them in
find the best fit and then just keep
generating model after model after model
and when the models blow up it just
automatically generates new models now
the problem with this is in practice I
mentioned it's just when they blow up
data scientists just go
wasn't me I don't really care it was
just a model and like
I just want to strangle people to death
often because I see this everywhere and
it's not even like it's not even in
firms I'm at it's like you see people on
LinkedIn posting this I look in forums
and communities I talk to friends of
mine that are running large teams I talk
to friends of mine that are on the data
science side and I'm like
I respect you and you're an expert and
there are good data scientists out there
so do not take this as they're all bad I
have friends that work in the data
science Community top-notch
um again master's degrees and they are
excellent and I bring these up I'm like
doesn't this just drive you absolutely
nuts like they fit do you have this
issue and I'll explain like this person
fit a model there's no consideration for
the actual usage of it it was all just
slapped together and yes the fit was
Stellar nobody understood the model
nobody could figure out how Dependable
the model is going to be and nobody
could tell me how robust the model was
going to be and there was almost no
testing because again why the hell would
you test anything when you can just slap
it into python or into R and it will
magically shoot out a model and it just
gives you magical operational you know
execution of it so ml Ops as we like to
call it
um but who cares how it really works
like it just and I asked you don't
doesn't this drive you nuts do you not
look at the mathematical equations do
you not need to understand how these
things are freaking working and my
friends like yeah yeah Dimitri it does
it does drive me nuts but you get over
it and I think that's going to be the
difference between so going back to the
point of this video uh that's going to
be the difference here between I think
machine learning data science and Quant
Finance I think that as we're seeing now
data science is starting to like segment
into
um
not very technical roles like simple
analytic roles where you can do an
undergrad I think the more technical
roles are starting to require Masters
again it's still there so I think in
many ways if you're on the job search
one easy way to sort them is to look at
does it require a master's degree it's
probably pretty rigorous if it does not
require a master's degree it's probably
going to be data analytics because again
they're all labeled data science but
again I think the problem with machine
learning data science as a whole is it
has to merge back in with traditional
statistics at some point and
just the way that it's set up and
operates
um I think you're going to continue to
see this weird segmentation inside of
machine learning and I think
unfortunately it's going to take
probably at least 20 years or more for
the machine Learning Community to
realize like we need to know what we're
doing before just slapping things in or
like trying to hurry and get a solution
and trying to reinvent the wheel every
single day which is just tiring beyond
belief to deal with and so I think that
piece of it once it finally becomes more
mature I think you'll finally get maybe
some new titles where you have uh like
we're having data scientists now it's
kind of viewed as like a not real
skilled position and now we have like ml
Engineers is a more skilled technical
position I think you'll continue to see
that split
um where eventually ml will hopefully
mature enough as a community and as a
field of study that it will come full
circle and actually utilize all the
tools just like stats is trying to do in
many cases and I don't know how we're
going to merge these two things back
together
um because I mean the terminology is
different current and yet it's the exact
same thing in many situations so that's
going to be a little bit of a challenge
here but I think you will start to see
that again those that actually need a
master's degree will continue to need it
and those it can do with an undergrad
continue to do with an undergrad I don't
think Quantum Finance though is going to
deviate down that
I have seen so many banks so it's a side
note wrap up here in a story I have seen
so many banks pushing for this because
they do not want to pay the price tag
that Master and PhD quants cost firms do
not want to pay it they are desperately
looking for solutions to hire undergrads
unfortunately though it just it never
results in good quality models because
there's so much effort work that goes
into this and even as someone who hires
and trains training someone with a
masters in a PhD is still a ton of work
even when you hire the best of the
brightest from the best programs in the
country in the world it is still a ton
of training and a ton of cost and
because of that it's just easier to hire
Master students who already have that
rigor who have that you know that drive
to actually get that graduate degree and
have all that additional education that
a university actually did for them and
they paid you know 70 to 100 000 for so
anyways thanks for listening thanks for
watching and as always until next time

thank you
