Stocks and bonds haven’t moved together like this in three decades – and that’s putting portfolios at risk, says State Street

It’s the time of year when many investors click on their brokerage account and set up their strategy for the next 12 months.

Matthew Bartolini, head of SPDR Americas Research at State Street Global Advisers, says there’s a key reason why a typical 60/40 portfolio –60% stocks, 40% bonds – is at risk.

He notes in the firm’s 2025 outlook that the rolling 12-month correlation of U.S. stocks and bonds has been positive for over 600 days, which is the longest streak since between 1992 and 1995. That link suggests that bonds won’t necessarily be a cushion if stocks fall, as indeed they weren’t in 2022.

That’s not the only risk – concentration risk has risen, in terms of companies, sectors and countries, he says. (Think Magnificent Seven, tech, and the U.S.)

“The key takeaway? Stock, sector, and geographical diversification attributes are as weak as ever for core equity exposures within the traditionally balanced portfolio,” he says.

His view is that investors should turn to so-called real assets – like gold, Treasury inflation-protected securities, commodities, infrastructure, natural resources, real estate and (intriguingly) digital assets.

Those assets could help hedge against inflation, generate yield or act as a diversifier to broad equities and fixed income, he says.

Bartolini also suggests allocations to private assets, though he does warn about their illiquidity.

An interesting chart from Variant Perception – they charted the VIX outperformance on days when the S&P 500 went down, vs. the S&P 500. Their conclusion was that in 2021 and 2023, the markets climbed a wall of worry, but in 2024, this stopped happening – “showing a lack of desire to hedge, even after the August vol event.”
