As a practitioner in this area, I’d say some of the authors here stand out as extremely influential to this day.

Clearly these include:

Cliff Asness (AQR is huge, lots of publications)

Ronald Kahn (early pioneer, standard book, successful ex. BGI people everywhere)

Neill Chriss (Almgren-Chriss)

Pete Muller (famous stat arb pioneer, PDT still going strong)

Not sure who I’ve overlooked.

I wonder how fun being a modern quant really is. It seems like one of those things that sounds more fun in your head, but the reality is different. Kinda like "studying physics", going pro in a sport, or becoming a rockstar. People see the end result and don't see how much work it takes to get there or what the day to day is really like

What kind of quant?

Trading huge equity portfolios and getting paid a lot? Pretty fun

Pricing structured products all day in a bank that charges you for lunch? Not great

Imo the fun quant stuff these days is about predicting returns and not pricing derivatives. As others have said here, the pricing part is mostly commoditised and more about managing software.

Yes although if you are predicting the returns swaps and options and so on then you need to be able to do both

I came across this guide (dated 2025) a couple years ago and thought it was interesting. Not a quant or even in finance though, so I don’t know how accurate it is: https://www.dropbox.com/scl/fi/da7zfjj2rplwzf2sfiriz/Buy-Sid...

Gappy is one of the more decorated, public figures in the space. That PDF gives a candid overview of what it's like to interview/work in the industry.

Gappy is very good but occupies a slightly odd role in that he's sort of a jobbing philosopher for hedge funds at this point

Im reasonably familiar with the exotics quant space. It’s essentially IT/data work - the days of sophisticated maths are mostly gone. There always was a lot of code, but these days for most people there’s little to no new maths. From what I’ve seen, post-2008 the job changed significantly, with more IT, less maths, more standardization - basically the job moved from bespoke everything to super industrialized. You’ll…

I started my career in derivatives. Mostly vanilla, but I did have a look in the exotics.

Intellectually, it's interesting when you start. There's all these weird payoffs that you are introduced to, and it feels like a game.

The thing is, there's a limit to how exotic things can get. People have already figured out how to price most of the things you can imagine, including all the things that customers normally ask for. Most of the day goes on looking after your hedges, basically implementing the model.

It's like a zoo. When you arrive there's a bunch of different, interesting animals. After a while, you've met them all. There's no new animals, just variations of existing ones.

However the thing that is really an issue is how the business works. Over time I came to the conclusion that the quants in the derivs space are really secondary to the salespeople. How important is the quant who can get the price right to within 1%, when the sales guy can talk the customer into overpaying by 5%? Sometimes it feels like the customer is not even shopping the structure around at all, he just feels comfortable with his sales guy and is willing to hand over a few million bucks of customer money with barely any thought.

Kind of reads 25 people's stories about "How I became a parasite". Why not create new things, instead of making a career out of leeching the wealth created by others?

Did you actually read them? I didn't go to NYC, but Money is fungible so it's a simple math problem. How much non-parasite good can you do making $50k/year * 10 years? Even if we ignore taxes and you donated your entire salary, that tops out at $500k worth. If instead you could make, say, $500k/year * 10 years, and then quit and form your own non-profit for $2,000,000 and do 4x as much good.

I get your point, but that was the exact logic of Effective Altruism and Sam Altman is now jailed for the Largest Fraud of All Time. It's a slippery slope.

and I wonder how much of your success / failure is luck vs advanced-anything. You could wager 7-figure bankrolls in vegas on blackjack or baccarat and _possibly_ double or triple it. Doesn't mean your equation-solving had anything to do with it (in fact it expressly doesn't in that case).

The salesman can't tell you how to hedge the product. If you can't hedge you will lose that 5% upfront pretty fast.

You need quants and sales and trading. Which is why all banks have all three.

the leeches are the publicly traded companies that are listed on the stock market. Any market should be happy to have more participants, unless you like price-uncertainty.
