Semi ETFs took in $12b leading up to the big bounce yesterday (btw semi ETFs accnt for 1% of ETF aum but took in 25% of the net flows this week) as degen traders bought the crap out of the Mon-Wed dip. Rewarded again w yest 7% bounce. You can also see just how insane these numbers are vs these ETFs' past history. Volume is the same, just a total explosion of activity(Eric Balchunas)
