According to JP Morgan’s 2026 Outlook, the traditional 60/40 portfolio — 60% stocks and 40% bonds — has left many investors heavily concentrated in just a few mega-cap tech stocks. The report notes that “diversification isn’t dead, just different,” and recommends moving toward a “60/40+” approach that includes alternative assets as a key part of the portfolio.
Factors Impacting Traditional Allocation
A static 60/40 portfolio may no longer behave the way investors expect. In prior cycles, bonds often provided ballast when equities sold off. But when inflation becomes one of the primary market force, that relationship can break down. Instead of offsetting one another, both asset classes can decline together.
Compounding the issue, stock–bond correlations are generally not static. During inflation-driven stress periods, correlations can turn positive — undermining the very diversification the 60/40 framework relies upon.
Finally, today’s equity markets are far more concentrated than in decades past. A passive 60% equity allocation may now embed significant exposure to a small group of dominant companies or sectors, which may increase portfolio-level risk in ways that historical comparisons fail to capture.

Active Management in Portfolio Implementation
Rather than abandoning the 60/40 framework, some market participants are adopting more flexible, actively managed approaches within the equity and bond sleeves such as the JPMorgan US Bond Active ETF. Active bond management allows for dynamic duration positioning in response to interest rate cycles, selective credit exposure based on issuer fundamentals and broader diversification across sectors and geographies among other potential benefits.
The 60/40 framework remains a foundational concept, but its passive implementation may face challenges in a changing market regime. As market dynamics evolve, the ability to adapt within the allocation is becoming a central consideration for many investors, often utilized through the active ETF structure.
