where your money actually sits, per cent
Friend tells me his fund averaged a great year, up 50, down 50, so it broke even. It did not. Rs 100 goes to 150, then loses half, lands at 75. The average of the two years is zero. The money is down a quarter. The average is a story. Your account keeps a different number.
