Ekdantaya (one-tusked) is another name for Lord Ganesh. His one tusk is symbolic for weeding out the bad from the good.
Many investors lack the ability to understand that holding on to bad investments for their portfolio can derail their financial journey. This is as equally damaging as the removal of a worthy investment from your portfolio.
Hence reviewing and rebalancing your portfolio semi-annually will ensure your journey of wealth creation is on track. It gives you the opportunity to weed out the duds that have been underperforming consistently and to replace these with new ones, if you want to accomplish your goals.
