Fund Ranking Method 

Fund Eligibility to be ranked

Each category must have 10 funds which are a minimum three-year-old. We do not consider AUM (Asset Under Management) as a criterion. Three-year data is used for ranking.

Rank Calculation

The fund is ranked based on the total score obtained for returns, risk, and risk-adjusted factors. The process for obtaining a ranking score for the fund is as follows:

  1. Calculated funds factor
  2. Calculate the mean and standard deviation for category
  3. Obtain the p-value for the fund using the mean and standard deviation of the category and factor value of the fund. 
  4. Multiply the p-value of the fund with the weight of the factor.


For return score calculation rolling return of the fund and percentage-positive returns are used.


For risk score calculation, VaR, standard deviation, and drawdown are used.

Risk-Adjusted Return

For risk-adjusted score calculation, Sharpe ratio, Sortino Ratio, and alpha are used.

  • An investment instrument that pools money from many investors and uses that money to invest in a diversified portfolio of stocks, bonds, or other securities.
