CNBC's Bob Pisani spoke with with Patrick O’Shaughnessy, CEO of O’Shaughnessy Asset Management and Dave Nadig, Director of Research at ETF Trends. They discussed a new investing strategy known as direct indexing – essentially, slicing and dicing preexisting indices and cherry-picking individual stocks to create a custom-made index all your own. What are the benefits and what are the burdens of such a methodology? In the ‘Markets 102’ portion of the podcast, Bob continues the conversation with Dave Nadig from ETF Trends about Bitcoin ETF's.
