Everyone knows what it takes to become a good investor. Hardly, anyone follows. Market veteran Nilesh Shah is of the opinion that there is one Duryodhana inside every investor that keeps him/her away from choosing the right path to successful investing. Duryodhana was one of the main antagonists of the Hindu epic legend Mahabharata. While sharing his views at the Business Today Market Summit in Mumbai, the managing director, and CEO, Kotak Mahindra AMC said regular and long-term investment coupled with disciplined asset allocation are the only mantras to become a successful investor.
