The better comparison is the Nifty 50 of the 70s. Which is today a Nifty 7 version. Many of those Nifty 50 stocks were good businesses for decades. But the stock investments collectively in that era were clunkers for a long time.

Which is why you can't simply buy and hold the "top N" stocks.

This is where & why you have to periodically run them through a momentum or relative strength filter.
