Rick Rieder's active bond ETF has just set a remarkable milestone—reaching $15 billion in just 644 days, making it the fastest-growing active bond ETF in history by a significant margin. To put that in perspective, the current category leader took considerably longer to achieve similar growth. In fact, this fund's expansion pace nearly doubled that benchmark and ranks as the third-fastest among all active ETFs, trailing only a couple of other standout performers. At this trajectory, it could potentially overtake the category leader down the line. The rapid accumulation of assets speaks volumes about investor appetite for this particular fund structure.
