Mathematical Analysis of Fund Performance
To assess whether a fund adds value, I use the Sharpe Ratio, which measures risk-adjusted returns:
Sharpe\ Ratio = \frac{R_p - R_f}{\sigma_p}Where:
- R_p = Portfolio return
- R_f = Risk-free rate (assume 2\%)
- \sigma_p = Standard deviation of portfolio returns
Example Calculation for TWCUX:
- Annualized return (R_p) = 9.2\%
- Standard deviation (\sigma_p) = 14\%
- Sharpe Ratio = \frac{9.2 - 2}{14} = 0.51
A Sharpe Ratio above 0.5 is considered good.
