BlackRock CEO Larry Fink has proposed a shift from the traditional 60/40 investment portfolio, suggesting a 50/30/20 model—50 per cent stocks, 30 per cent bonds, and 20 per cent private assets like real estate and infrastructure.

BlackRock Chief Executive Officer Larry Fink is proposing a new tweak to an age-old investing formula. Instead of a traditional 60/40 split between stocks and bonds, the prominent asset manager wants everyday investors to branch out and diversify into private market assets.

When it comes to investing, a 50/30/20 allocation to stocks, bonds and private assets may become the "future standard portfolio," BlackRock's Larry Fink says.
