An AI Bubble Could Hit Stocks. Inflation Could Hit Bonds. How Do You Diversify and Keep Both?
For wealth professionals, the discussion focuses on portfolio construction trade-offs that can affect client conversations: how added strategies are funded, what collateral they require, and whether investors can stay with a diversifier through long periods of disappointment.
Summary
By the markets & outlook deskCorey Hoffstein and Adam Butler discuss why diversification is difficult for investors to maintain and how return stacking changes what can be held alongside stocks and bonds. They cover inflation shocks that hurt stocks and bonds together, managed futures as an example, leverage and collateral questions, low correlation versus crash protection, and liquidity lessons from 2008.
- Return stacking lets an investor keep the stock and bond exposure of a 60/40 portfolio and use futures to add another strategy, introducing leverage.
- An inflation shock can hurt stocks and bonds at the same time, making the case for owning something different easier to see.
- Low correlation is not the same as protection during a stock market crash; a strategy with little connection to stocks can still lose money when stocks fall.
- In 2008, some hedge funds suspended withdrawals just as investors needed cash to rebalance, highlighting liquidity issues when liquid futures are paired with illiquid hedge funds.
