VGSH: Why Short-Term Treasuries May Outperform Stocks Over The Next Decade

With the S&P 500 trading at historically high valuations, including a 38.93x CAPE ratio and a 30.07x P/E (3.32% earnings yield), short-term Treasuries like the Vanguard Short-Term Treasury Index Fund ETF (VGSH) are presented as a compelling alternative, currently yielding 4.11%. The analysis suggests that due to anticipated multiple compression, the S&P 500 could deliver annual total returns as low as 3.22% over the next decade, making low-risk fixed income a potentially superior strategy for capital preservation and even outperformance in the current market cycle.

Analysis

Current market dynamics present a rare inversion where the anemic earnings yield of the S&P 500, at 3.32% (based on a 30.07x P/E ratio), is surpassed by the yield on short-term Treasuries, with instruments like the Vanguard Short-Term Treasury ETF (VGSH) offering 4.11%. This valuation strain is further underscored by a cyclically adjusted P/E (CAPE) ratio of 38.93x, a level historically seen only once before, preceding the dot-com bust. A forward-looking projection suggests that even with an optimistic 6% annual earnings growth, the S&P 500's total return could be compressed to approximately 3.22% annually over the next decade due to a necessary reversion of its valuation multiple. In this context, short-term government bonds are positioned as a compelling vehicle for capital preservation and potential outperformance. The Vanguard Short-Term Treasury ETF (VGSH), which tracks 1-3 year Treasuries with a low 0.03% expense ratio, is highlighted as a primary option, though its 2-year average maturity introduces more price volatility than alternatives like the iShares Short Treasury Bond ETF (SHV), which focuses on maturities under one year.

Key Decisions for Investors

• Given the S&P 500's historically elevated valuations and the risk of multiple compression, investors should consider trimming exposure to broad-market equity indices and re-evaluating their risk/reward assumptions for the next decade.
• A tactical allocation to short-term Treasury ETFs like VGSH should be considered to capture a yield (4.11%) that currently exceeds the S&P 500's earnings yield (3.32%), offering a defensive posture with the potential for superior risk-adjusted returns.
• For investors prioritizing capital preservation over very short time horizons, an ETF with a shorter duration like SHV may be more suitable than VGSH, despite its higher expense ratio, to minimize price volatility risk.
• Rather than fully divesting from equities, consider using low-risk, yielding instruments like Treasuries to build a capital reserve, positioning the portfolio to capitalize on more attractive entry points in the stock market should a valuation correction occur.
