Oopsfolio

What it does

Oopsfolio turns "I should've bought the stock" into a number. Enter any product, price, and purchase month, and we show what that money would be worth in the company's stock today — using real historical market data. Get a personalized roast, share a regret card, and post your worst misses to the Hall of Shame.

Find out how rich you'd be if you had invested in the company instead of buying their product. Real stock history, brutal roasts, shareable regret cards.
