For a long time, you could make plenty of money and sleep easy at night with a simple 60/40 portfolio. You put 60% of your money in stocks and 40% in Treasuries. The stocks generally went up. The Treasuries cushioned you during times of volatility and provided income. Then we got the worst inflation in 40 years, and the Treasury part of those portfolios got obliterated. So does it still work? And if not, how should an investor think about their own personal allocations to various asset classes.
