A record 23% of the flows are now going to young ETFs less than 3yrs old- a relatively new phenomenon. It used to take longer but investors are pretty trusting of ETFs and willing to use new ones (plus many are legacy active brands) not to mention about HALF of all ETFs are under 3yrs old so there's just sooo many young products. It adds up. Nice find from @psarofagis(Eric Balchunas)
