Can you beat the S&P 500 when the era is hidden?
Blindfolio keeps the index in the room. Every round ends with the same honest question: did your choices beat simply buying the S&P 500?
The index stays visible
Your return is shown next to the S&P 500 for the same period. A big nominal gain can still be a weak result if the market did better.
Market regimes stay hidden
Inflation, crashes, bubbles and rate shifts change what the index does. You learn the exact years only after the round is over.
More useful than bragging
Sometimes the index is hard to beat because it already owns the winners. Sometimes careful blind stock selection really does add value.
