There’s a number that used to matter a lot in portfolio construction and has been quietly ignored for most of the last 15 years. It’s the equity risk premium — the extra return investors expect to earn for owning stocks instead of just buying government bonds.
Right now, that number has nearly disappeared.
The S&P 500’s realized earnings yield is roughly 3.4%. The 10-year Treasury note is sitting around 4.37% to 4.40% as of late June. That leaves the gap at roughly negative 110 basis points — the widest negative reading since 2003.
Translation: bonds are now paying more than stocks, on a realized basis, for the first time in over two decades. And Treasuries, unlike stocks, don’t require you to be right about earnings growth, margin expansion, or AI monetization timelines.
This matters for a very specific reason. For the better part of 2009 through 2021, stocks always won the yield comparison. Rates were so low that there was no real competition. The TINA trade — There Is No Alternative — drove a 15-year bull market that pushed S&P multiples into the 26x to 30x range without serious pushback from bond math. That math is now fundamentally different.
The counterargument is forward earnings. Using projected rather than realized earnings, the picture shifts somewhat. S&P earnings are expected to grow roughly 21% in 2026, followed by 14% in 2027 and 11% in 2028. If that holds, the forward earnings yield is more competitive. And the companies driving that growth — particularly in AI infrastructure — are largely spending from cash flow, not borrowed money, which makes them less sensitive to rate increases than traditional rate-sensitive sectors.
But here’s what the bond market is saying more broadly. The $50 trillion market for G7 sovereign debt has seen long-term yields climb to two-decade highs as investors demand more compensation for structural inflation and recurring supply shocks. Markets are now pricing in a meaningful probability of a rate hike later this year — around 63% odds of a September move as of late June. Goldman Sachs has already pushed its first expected rate cut all the way to June 2027.
The Schwab fixed income team put it plainly in their mid-year outlook: inflation remains sticky, the Fed appears likely to stay patient, and the 10-year may hold in the 4% to 4.5% range with risks tilted to the upside.
What that means in practice is that the investment-grade corporate bond market — which offers spreads above Treasuries — is now genuinely competitive with dividend-paying equities on a risk-adjusted basis for the first time since the early 2000s. Short and intermediate duration bonds are yielding enough to matter in a portfolio context.
The part people keep skipping is what this does to relative sector positioning inside equities. When bonds offer a real alternative, the sectors that benefit most are the ones with the most bond-like characteristics — predictable cash flows, strong balance sheets, pricing power. The sectors that lose are the ones pricing in multiple years of future earnings at premium multiples with no current dividend support.
The equal-weighted S&P 500 has been quietly outperforming the cap-weighted index throughout 2026. The Russell 2000 is up roughly 21% year-to-date versus less than 10% for the S&P 500. That broadening isn’t random. It’s what happens when capital starts to flow toward value and away from a concentrated bet on a handful of mega-caps that have already priced in the best-case outcome.
None of this means the bull market is over. The earnings growth underpinning this market is real in a way it wasn’t during the zero-rate era. But the old portfolio math — hold concentrated tech, ignore bond competition, trust the AI premium — is operating in a very different rate environment than the one that made it work.
If you haven’t stress-tested your equity holdings against a world where Treasuries pay 4.5% and stay there through mid-2027, now is a reasonable time to start.
