Tom Nathan's value investing blog

Welcome!

My name is Tom Nathan – I’m a recent (June 2025) MBA graduate of the Kellogg School of Management at Northwestern University and trying to break into public equities research / investing. At school I participated in Kellogg’s asset management practicum, received 2nd place in the Thompson Street Investment Competition, and was a Booth Investment Competition finalist.

I’m a self-taught value investor, have managed my personal portfolio for over 10 years, and love the work! My background is in strategy consulting / private equity due-diligence (L.E.K. Consulting) and fintech strategy (Affirm). Please contact me at thomasnathan0501@gmail.com or via my LinkedIn: https://www.linkedin.com/in/tom–nathan/

For an example of my work, see my investment write-ups below (Chime, Fiserv, Lululemon). Thanks for visiting!
