What if you invested at literally the worst possible moments in market history? According to Ben Carlson, the co-host of the Animal Spirits podcast and an advisor at Ritholtz Wealth Management, even the world's worst market timer could still become a millionaire. Carlson's new book, Risk & Reward, explores why long-term investing remains so psychologically difficult.

On this episode of Trillions, Eric Balchunas and Joel Weber speak with Carlson about his new book, which implores you to stop panicking and just stay the course. They discuss the genius of boring index funds, "fun accounts" as a behavioral release valve, whether buffer ETFs are financial Xanax and how the ETF wrapper may help turn tax efficiency into the new alpha. They also drill into Carlson's other big launch: Goaltender (GTND), a new ETF from Ritholtz, and go over why wealth managers are becoming ETF issuers.
