In SIP, a fixed amount of money is debited by the investors in bank accounts periodically and invested in a specified mutual fund. The investor is allocated a number of units according to the current Net asset value. Everytime a sum is invested, more units are added to the investors account. The strategy claims to free the investors from speculating in volatile markets by currency cost averaging. As the investor is getting more units when the price is low and less units when the price is high, in the long run the average cost per unit is supposed to be lower. SIP claims to encourage disciplined investment. SIPs are flexible, the investors may stop investing a plan anytime, or may choose to increase or decrease the investment amount.
