BlackRock vs. Vanguard: The world's biggest asset managers don't see eye to eye on the classic 60/40 investment strategy.

• A 60/40 investing strategy allocates 60% of a portfolio to stocks and the remaining 40% to bonds.
• The classic approach delivered steady returns for investors for nearly a decade – then cratered in 2022 as equities plunged.
• BlackRock and Vanguard, the world's biggest money managers, now disagree on how the portfolio will fare over the coming years.

The world's two largest money managers no longer see eye to eye on the classic 60/40 portfolio.

BlackRock and Vanguard – both of which manage over $8 trillion worth of assets – are split on the strategy, in which investors allocate 60% of their portfolio to stocks and the other 40% to bonds.
