Ejemplo

daily_returns = [0.01, -0.005, 0.008, 0.003, -0.002, 0.006, 0.004]
vol = annualized_volatility(daily_returns, 252.0)
# Volatilidad anualizada (std * sqrt(252))

Notas

Formula: std_muestral(returns) * sqrt(periods_per_year). Usa desviacion estandar muestral (n-1) para ser consistente con la practica financiera. Retorna 0.0 si hay menos de 2 retornos o periods_per_year es menor o igual a cero.
