Passive investing? That S&P 500 index fund is basically a tech fund: McGeever
SPY•Passive flows continue to pile into crowded trades
Passive investing itself arguably exacerbates the problem by pushing more money into already crowded trades — and passive investment flows have long dwarfed their active counterparts. US equity funds currently hold over $16 trillion in assets under management, based on funds that report at least weekly, according to Société Générale, and roughly 70% of that is now passively managed.
These passive funds have attracted cumulative inflows of almost $3 trillion since 2019, while investors have pulled around $1 trillion from actively managed funds, SocGen analysts note.
Even the concentration within the passive fund universe is rising rapidly. The three largest listed passive S&P 500 index exchange-traded funds (ETFs) — State Street SPDR SPY.P, iShares Core IVV.P, and Vanguard's VOO VOO.P — have nearly $2.7 trillion in assets under combined management. It's a near-constant, one-way flow.
