With bond yields surging to 4.7%, T-notes are looking like a better deal than the pricey S&P, says the Research Affiliates’ formula

Research Affiliates’ Asset Allocation Interactive projects just 3.2% annualized returns for U.S. large caps and 1.7% for U.S. large-cap growth through May 2036, versus 4.6% for intermediate Treasuries and 3.5% for cash. The article argues that high valuations and rising yields have made bonds and cash more attractive than the S&P 500, with U.S. large-cap growth ranking last among more than three dozen asset classes. It also highlights better expected returns in undervalued areas such as Emerging Markets Value, Europe, and U.S. small caps.

Analysis

The second-order implication is not just “equities expensive, bonds cheap,” but that the market is shifting from a scarcity-of-growth regime to a scarcity-of-carry regime. If intermediate Treasuries can deliver mid-single-digit nominal returns while large-cap growth re-rates lower, the risk-adjusted hurdle for crowded duration-in-equity trades rises sharply. That is especially toxic for passive-cap-weighted portfolios because the same handful of mega-cap names are doing most of the index work, so any valuation compression transmits disproportionately into broad-market sentiment and index-level volatility.

The biggest loser is likely not just the named mega-cap tech cohort, but the entire ecosystem that monetizes their momentum: derivatives market makers, thematic ETF providers, and structured-product distributors that have been selling upside participation on the assumption of persistent trend. A prolonged multiple reset in NVDA/GOOGL/TSLA would also pressure adtech, cloud capex suppliers, and consumer discretionary beneficiaries that were priced as secondary call options on AI and EV adoption. Meanwhile, fund flows could become self-reinforcing into value, short-duration credit, and international cyclicals as allocators chase income and lower starting multiples.

The key risk to the thesis is that valuation compression can be slower than expected if rates peak and earnings keep compounding faster than feared. Over the next 1-3 months, a macro pullback in yields would likely trigger a violent short-covering rally in the most crowded growth names even if the 10-year remains structurally unattractive over a 12-24 month horizon. In other words, the investment case is strongest as a medium-term relative-value trade, not an all-in directional macro short.

The contrarian angle is that the market may already be partially priced for mean reversion in mega-cap growth, but not for a regime where cash itself out-earns equity risk. If that persists, the real underowned trade is not simply short tech, but long high-quality fixed income and non-U.S. equity where starting valuations are still compatible with positive real returns. The best expression is to harvest premium on the crowded winners while using duration as ballast, rather than trying to pick the exact top in names with strong balance sheets and buyback support.

Key Decisions for Investors

• Add duration via intermediate Treasuries (IEF/IEF equivalent) over the next 2-6 weeks; target a 6-9% total return over 12 months if yields normalize 50-75 bps lower, with limited equity-beta correlation.
• Initiate a relative-value short basket in NVDA/GOOGL/TSLA against a long in quality bond proxies or cash-like instruments; time horizon 3-9 months, aiming for multiple compression rather than earnings misses.
• Use put spreads on QQQ rather than outright shorts to express the view; 3-6 month tenor offers convexity if the mega-cap bid unwinds, while limiting drawdown if rates roll over.
• Rotate incremental risk budget into value/international cyclicals and EM value exposure; prefer EEM/VEA-style exposure over U.S. large-cap growth for a 12-24 month horizon where valuation mean reversion should dominate.
• For existing long-only books, reduce factor concentration by trimming passive mega-cap overlap and reallocating to short-duration credit; this lowers left-tail risk if the market transitions from momentum-led to carry-led.
