CNBC's Bob Pisani spoke with  Ed Rosenberg, Head of ETFs for American Century Investments, Jerome Schneider, Head of Short & Low Duration Portfolio Strategies at PIMCO, and Ben Johnson, Director of Global ETF Research at Morningstar. They discussed the age-old battle between active management and passive strategies - armed with fresh data from Morningstar’s latest report. Overall, passive is still the big winner despite a very topsy-turvy couple of years. In the ‘Markets 102’ portion of the podcast, Bob continues the conversation with Ben Johnson from Morningstar.
