CNBC’s Bob Pisani spoke with Sylvia Jablonski, CEO of Defiance ETFs, and D.J. Tierney, Senior Investment Portfolio Strategist at Schwab Asset Management.They dug deep into a new ETF on the market that’s looking to capitalize on a massively popular way to make short-term market bets – zero-day options. The world’s first-ever “zero days to expiration” ETF is here, and it’s making big waves in the ETF business – particularly as options trading has been red-hot in recent years. They also broke down the latest ETF flows from the third quarter and told investors how to equip themselves for the fourth quarter. In the “Markets 102” portion, Bob continued the conversation with D.J. Tierney from Schwab.
