Purpose: To get high returns with low riskIdeal investment duration: 4+ yearsRationale: If you want high returns, you have to go with equity mutual funds. In equity mutual funds, the least risky is the category large cap funds. Large cap funds invest in the biggest companies of the country and have a relatively good track record of performance. They are also better positioned to weather ups an downs of the market. In this portfolio, I have included the best large cap funds that are low risk and give high returns.
