#Sortino Ratio

The Sortino ratio is a magical sieve in finance that filters out the screams of downward volatility, boasting only of its well-behaved returns. It politely ignores catastrophic drawdowns, glorifies tame gains, and lulls investors into a comforting illusion of perfection. By counting only positive days, it nurtures an inflated sense of self-satisfaction and 'risk-managed' complacency. In truth, it is a black box concealing the market's murkiest downturns under a shiny guise of statistical sophistication.
