What did Warren Buffett mean when he said, “Diversification is protection against ignorance. It makes little sense if you know what you are doing.” By Investopedia | Updated October 18, 2018 — 9:48 PM EDT

A:
Billionaire investor Warren Buffett famously stated that "diversification is protection against ignorance. It makes little sense if you know what you are doing." In Buffet's view, studying one or two industries in great depth, learning their ins and outs, and using that knowledge to profit on those industries is more lucrative than spreading a portfolio across a broad array of sectors so that gains from certain sectors offset losses from others.
