Since the establishment of Modern Portfolio Theory in the 1950s, the 60/40 portfolio has been the “set it and forget it” gold standard of investing. Its logic was simple – when stocks took a tumble, bonds acted as the shock absorber.

But, in 2026, that spring has gone damp. Bonds are no longer behaving like the defensive anchor they once were.

Recent research from KKR confirms what investors might already have suspected – a fraying relationship between stocks and bonds. Instead of moving in opposite directions, the two asset classes are becoming increasingly positively correlated. When the “risk-off” switch is flipped, both sides of the traditional portfolio are now bleeding at the same time.

The Great Repositioning

This shift isn’t just a theoretical headache for retail investors; the world's biggest “smart money” players have been front-running this reality for years.

Norway's $2.1 trillion Sovereign Wealth Fund, the world's largest, has slowly rewritten its playbook. Once a conservative giant with roughly 40% in equities in the late 2000s, the fund has pushed its equity exposure as high as 70%.

Yet, despite the volatility, Norway is doubling down on growth. In a recent interview with the Financial Times, Finance Minister Jens Stoltenberg reiterated the commitments to have roughly half of the fund invested in the U.S., "because the ​American stock market is so dynamic and reflects the strength ‌of ⁠the U.S. economy.”

Alternatives: The New Ballast

If bonds can't protect you, what can? JP Morgan suggests that macro uncertainty, driven by sticky inflation and fiscal dysfunction, needs a broader toolkit.

The bank points to 3 core reasons to pivot toward alternatives:

  • Flexibility: When bonds and stocks move in tandem, hedge funds can navigate volatility by playing shifts in currencies and interest rates.
  • Innovation Scarcity: With the S&P 500 heavily concentrated in mega-cap tech, the most transformative growth in AI and deep tech is now happening in private markets.
  • Inflation Resilience: Core infrastructure provides durable, inflation-linked cash flows that bonds currently lack.

De-risking the “New Normal”

For those looking to shore up their defenses without simply buying more volatile stocks, Fidelity recommends building “ballast” through specific sub-sectors. The firm's Investment Director, Tom Stevenson, suggests "fixing the roof while the sun is shining," and finding assets that don't respond to negative events in the same way.

Fidelity's 2026 de-risking strategy includes:

  1. Short-Duration Bonds: Using tools like the AXA Sterling Credit Short Duration Bond Fund to reduce sensitivity to interest rate hikes. The US equivalents would be Vanguard Short-Term Corporate Bond ETF (NASDAQ:VCSH), or the iShares 1-3 Year Investment Grade Corporate Bond ETF (NYSE:IGSB).
  2. Gold: Using the physical gold exposure as an "insurance policy" during geopolitical stress. Vehicles include Sprott Physical Gold Trust (NYSE:PHYS) or SPDR Gold Shares (NYSE:GLD).
  3. Infrastructure: The First Sentier Global Listed Infrastructure Fund (NASDAQ:FLIIX) invests at least 80% of its net assets in global infrastructure company equities, while also providing a steady yield.
