Importance of investment horizon
Investment horizon is another important aspect which influences returns. They are directly
related i.e. longer the investment horizon the better the returns. The reasons for this are
two-fold – Rupee Cost Averaging and the Power of Compounding.
Rupee Cost Averaging (RCA)
RCA involves investing a set amount of money at regular intervals over a long period of time.
This not only takes the guess work out of ‘timing’ the market but you automatically buy more
units when prices are lower and fewer units when prices are higher. Thus, over time you pay
lower average cost per unit.
Power of Compounding
Compounding is a simple concept that offers astounding returns: if you park your money in an
investment with a given return, and then reinvest those earnings as you receive them, your
investment grows exponentially over time. With simple interest, you earn interest only on
the principal (that is, the amount you initially invested); with compounding, you earn interest
on the principal and additionally earn interest on the interest. In other words, it’s a way of
making your money work harder for you, and is perhaps the most powerful tool that an average
investor can use to plan for many of life’s financial goals, including retirement.
The illustration below gives an indication of the importance of disciplined investing and
returns generated over the investment horizon.
