When investing for the long term and that too in a product with a lock-in period, the decision between the best and the consistent performer becomes critical. While chasing the best performer might seem tempting, but a steady, consistent performer could be a more reliable option. If considering investment in a tax-saving mutual fund, such as equity-linked savings scheme (ELSS), do remember that you will be tied for three years, even if the fund underperforms. So, it is important to choose a fund that has a sound track record of consistent performance.
