## Ejemplo
|
|
|
|
```python
|
|
daily_returns = [0.01, -0.005, 0.008, 0.003, -0.002, 0.006, 0.004]
|
|
sr = sharpe_ratio(daily_returns, 0.02, 252.0)
|
|
# Sharpe ratio anualizado
|
|
```
|
|
|
|
## Notas
|
|
|
|
risk_free_rate es la tasa anual (ej: 0.02 para 2%). Se convierte a tasa por periodo internamente.
|
|
periods_per_year indica la frecuencia de los retornos (252 para diarios, 12 para mensuales).
|
|
Retorna 0.0 si la desviacion estandar es cero o la lista esta vacia.
