BlackRock’s iShares Core S&P 500 ETF (IVV) has recorded negative year-to-date flows of $7 billion, a sharp reversal from its typical $80 billion annual contribution. This underperformance has left BlackRock as the only major ETF issuer not reaching record territory this year. The outflows coincide with the rapid rise of SPYM, which has attracted $60 billion in year-to-date inflows. Market observers suggest BlackRock could respond to this competitive pressure by reducing IVV fees to 2 basis points or even 1 basis point to regain market share.
