Nifty Next 50 beats Nifty 50 most times. Time to move there?

When it comes to large-cap investing, many investors instinctively pick a Nifty 50 index fund. For instance, ICICI Prudential's Nifty 50 has net assets worth over Rs 12,600 crore, whereas its Nifty Next 50 index fund is a little over half its size, at about Rs 6,700 crore. This is a common theme for all fund houses. Their Nifty 50 funds attract most investor money, while the Next 50 funds get a step-sibling treatment.
