Another $16b into ETFs yesterday, now +$73b for the week. Only two years ago that would be considered a good month. Now +$348b YTD in 34 trading days = $10b/day = $2.5T ann pace (last yr set record w $1.5T). What's behind this extra gear? The number of star ETFs has grown while the bench is getting deeper at same time. Lot of funds you never heard of contributing sizably. (And I was told tokenization (and DI before that) was going to kill this industry. I guess ETFs didn't get the memo! )(Eric Balchunas)
