This tax-saving ELSS fund gave 14.3% returns in five years; should you invest?

Axis ELSS Tax Saver Fund: This fund has undergone a shift in its investing stance in recent years. The big change is in the form of a more diversified portfolio (currently around 60 stocks), against the earlier preference for a compact portfolio of around 40 stocks. This has also reduced the heavy concentration at the top end of its portfolio, with the fund diluting positions in its top bets. It has also sizeably hiked its presence in mid-cap stocks, even as it retains a large-cap tilt. Should you invest?
