Since I just turned 35 years old, I figured I would a podcast episode on the journey and the lessons I learned. It was a mixed bag of great years, some struggles, and now coming out the other side. Quantitative finance is a wild ride and never the same for any two professionals.


Reflecting on 30 Years: The Journey to Becoming a Quant

As many of you know I work in a high paying field and rub shoulders with many wealthy people. That being said, I didn't grow up around Wall Street or any other high powered field. I was an average American who took an interest in quantitative finance and ended up falling in love with statistics and economics. I tend to understand people from a variety of backgrounds because I wasn't sheltered in one group. This perspective has allowed me to understand some of the biggest issues America faces however it is very frustrating sitting in the middle. No one wants to be in the middle anymore as the rise of the internet has made it so easy to segregate people based off of race, religion, social status, wealth, politics, and many other random groups.

We need to come together as a nation and embrace what makes America unique. The values of capitalism, family, freedom, and hard work seem to have become taboo as the new "acceptance of everyone" mentality continues. There is right and there is wrong but there is also a need for deeper discussions and debates on topics.

Should you have friends at work?

Of course! You need a network around you. You need people to talk to who can relate to you. It makes work easier as you understand your colleagues better, it helps find work in the future, and it makes it enjoyable to go to work.

That being said, I rarely ever hang out with my colleagues outside of work. However I do grab lunch with past colleagues and my Santander friends did all text and call congratulating me on my new daughter.

A subscriber asked how I paid for my masters degree as they are very expensive. The short answer on how I paid for it was working part-time and taking out government loans. For my undergrad my parent's paid the first 1.5 years and then I got married and was poor so the school covered my tuition. I also worked two part-time jobs during my undergrad to pay for rent, books, food, and other necessities. I would recommend students really focus on their school work when possible however if you can't afford school, you need to work.

A subscriber asked how I manage my family, working as a quant, two YouTube channels, and a fair amount of hobbies including my homestead. There are really four tips that allow me to manage my schedule. It is also important to realize I do not succeed at everything. Social media makes it look like everything is running smooth with minimal stress however my life can be very stressful however I find the rewards from juggling so many thing worth the effort. So here are me four tips:

1) Repetition
2) Paper Planner
3) Advanced Prioritization
4) Perspective

An industry professional asked me why is it so hard to get changes made within a company. They had made some suggestions for improving model validation however they were told there were resource constraints. Resource constraints are very real however this often includes company politics. For example, even if your team can make changes that will improve efficiency, save money, and great better outcomes it will disrupt other teams. As a manager or department head you now have to convince other departs to make the changes which will cost them and money. This impacts company and team performance in the short-run which impacts their bonuses. It is also important to realize that many projects and changes will fail. Failures cost more time and money which is also a consideration.

As advice, ask yourself, am I willing to lose my job over this change? If the answer is yes, then push for the change really hard. If the change is needed but not critical you might consider just waiting and asking later down the road. Resources could change or people could move jobs making the request easier.

In quantitative finance I hear a lot of students say, "I love money" implying that will make them good at quant finance. It is a very shallow statement and one that shows the student hasn't thought much about that statement. The students that do truly love money for the sake of money are shallow people that won't make it in quant finance. Now that being said, I think many students making the statement either find economics interesting which covers how money transfers value, stores value, and how people create value. And or they love what money can do for them. Money can buy you things such as experiences, assets, or even provide financial freedom which is why people save or invest for retirement.

So before you tell someone you love money, think twice. Communicating why you would be a good fit for finance or quant finance has nothing to do with loving money. Those that excel at quant finance do so because they love stats, math, and understanding how the world works.

The biggest lie in quant finance is that you can do everything required at the highest level of a model. This includes data engineering, model development (quant research), implementation (quant dev), and be the end user (often a trader or operations team). This full stack quant does exist however they are never the best at everything and they often work in a very specific niche. Examples of a niche could be, auto loans, equity HFT, commodities, securitization, or etc. The systems, languages, math, stats, financial theory, and business uses are all different.

I would encourage people to focus on one main area (data engineer, quant, quant dev, or business user) and dig as deep as possible. There are a lot of topics inside of each of these and it is easier to jump around business types than to try and cover too many areas with non-overlapping skills. 

For this Thanksgiving season I would like to express my gratitude for my dad. My dad was a traveling salesman and the reason my mom was able to be a stay at home mom. The one skill that I am most grateful for is my work ethic. I learned to work along side my dad as a kid growing up. The example my dad set helped engrain in my the need and desire to work. I spent a lot of my childhood working on our house, cleaning cars, or traveling across the country for my dad's job.
