You have selected two funds with different investment objectives and character. While HDFC Top 200 is one of the best performing large- and mid-cap funds, with an impeccable track record; the same cannot be said of Magnum Contra, a multi cap fund. This fund’s performance has been in the decline in recent years. There are better performing multi cap funds such as HDFC Equity or Quantum Long Term Equity that you can switch to.
There is a lesson for you from this investment; review and track the performance of your fund holdings at least once a year and take necessary action if there is a need.
