CNBC's Bob Pisani spoke with Jay Jacobs, Head of Research and Strategy at Global X ETFs – along with Alex Shephard, founding partner at ETF Action. They discussed the lay of the land for ETFs this year – what the most pivotal themes and trends driving the action were – and what investors can expect as they prepare to ring in a new year for the markets. Plus, while the so-called hot “thematic” trends like ESG and crypto may appear to be all the rage, the flows may be telling a different story. In the ‘Markets 102’ portion of the podcast, Bob continue the conversation with Jay Jacobs from Global X Funds.
