Eminent portfolio manager Paul Black says the best way investors can ensure consistent wealth creation is by betting on good growth companies with superior culture that have a strong competitive advantage over peers. Black says in order to become a successful growth investor, one should be optimistic about the future because optimists can conquer great heights. “If you look back through history, optimists are the ones who ultimately get it right. Buffett says it all the time: never bet against America. I'd say never bet against great growth companies with superior cultures and the ones that are highly competitively advantaged,” Black said in an interview with CapitalAllocatorsPodcast.com.
