About

Hey there — I’m Ruitao Wang (most people call me Ray), and this is my little corner of the internet for thinking out loud about quantitative finance — and, increasingly, the AI reshaping it.

What I’m into

I spend most of my time around quant research, and these are the topics I keep coming back to:

  • Portfolio Construction — optimization, risk management, and asset allocation
  • Asset Pricing — factor models, stochastic discount factors, and market dynamics
  • Statistical Methods — empirical methods in finance and dynamic modeling
  • AI & Machine Learning — applying modern ML to markets and research; I’m also studying CS/AI part-time at Penn, so expect this corner to keep growing

About this blog

This is a casual research-and-learning blog, not a journal. I write here to challenge myself to think in a structured way, to document what I’m learning, and to connect with other people who find this stuff as fun as I do. Expect posts on portfolio optimization, statistical methods, asset pricing, and — more and more — where machine learning meets markets, plus the occasional detour into the tools I build along the way.

Say hi

I’d genuinely love to hear from you:

Thanks for stopping by!
