Understanding markets,
businesses and decisions.

I'm Brian Cui. My interests sit at the intersection of finance, economics, investment research, and data analysis.

I'm particularly interested in understanding how businesses create value, how markets respond to changing incentives, and how data can help separate useful signals from noise.

I built this website as a place to organize my projects, research, and ideas — instead of letting them disappear into spreadsheets, notebooks, presentations, and browser tabs.

Over time, I plan to use this space to document more work across investment analysis, market research, economics, and applied data projects.
