The Cohorts · Vintage portfolios
36 vintages · 27-stock universe
Every portfolio Mr. Market would have picked, archived.
Each cohort is a frozen, buy-and-hold portfolio created at a historical date — the top 5, 10, and 20 most-undervalued names by Mr. Market's protocol at that moment, locked in, and tracked forward. Browse them by year. Click into any one to see the constituents and their performance since inception.
