There’s been roughly 10 billion individual ETF trades in the past 25 years with almost no issues. This McDonald’s-esque track record of happy customers is one of the reasons ETFs have become so popular. One of the main reasons behind the stellar track record of trading is the important role played by ETF market makers, who provide liquidity for popular ETFs but also lesser traded ones— stepping in to be a buyer or a seller when there are none.  On this week’s Trillions, Eric and Joel speak with veteran ETF market maker Chris Hempstead of Deutsche Bank as well as Annie Massa of Bloomberg News, who just wrote about the secretive market maker Susquehanna in the latest issue of Bloomberg Markets. The discussion covers ETF mechanics, liquidity, and poker. Yes, poker. See omnystudio.com/listener for privacy information.
