A portfolio simulator with real historical pressure
Blindfolio is not only a stock-picking game. It asks how you spread capital when you do not yet know whether the next decade rewards risk, patience or caution.
Allocation changes the result
Stocks may lead, but bonds, gold, oil, cash and index funds can completely change how a hidden-era portfolio behaves.
Monthly decisions
You receive recurring income and decide whether to add to winners, diversify, hold cash, or move into new instruments.
A clear final breakdown
At the end you see total return, CAGR, drawdown, trades, best and worst positions, and the comparison with the index.
