It is funny. what is Regular investment? It is through some broker. The broker may give back some of the commission; but the point is that the Company gives very less commission to the agent but keeps the NAV (price) quite low.
I suggest not to invest in mutual fund because the Fund never passes on the entire benefit to the unit holder; rather keeps lot for itself. Hence, I suggest that the Fund investing in equities may be studied and 5-10 Companies should be selected; and shares of these 5-10 companies should be purchased whenever any of these is at 52 weeks low. No hurry should be made.
