Not to be outdone by Fidelity, flows to the top 10 funds were very active today, totaling nearly $1 billion, according to Eric Balchunas, ETF analyst at Bloomberg. It was the second best day since mid-March. A total of $3.30 billion has flowed in the past four weeks, and a net inflow of $15 billion this year (the highest in our 12-month estimate). The "third wave" is turning into a tsunami. It was previously reported that FBTC had net inflows of $378.70 million yesterday.
