The S&P Just Rallied 8 Straight Weeks. Treasury Yields Are Saying It's a Problem.

Key Concepts

• Fed Model: A valuation framework comparing the S&P 500 earnings yield (the inverse of the P/E ratio) to the 10-year Treasury note yield to determine if stocks are overvalued or undervalued relative to bonds.
• Earnings Yield: The earnings per share divided by the share price; represents the percentage of earnings generated per dollar invested in a stock.
• Valuation Compression: The process where rising interest rates force a decrease in P/E multiples, often leading to lower stock prices despite earnings growth.
• Transmission Mechanism: The process by which economic shocks (like rising oil prices) translate into broader market impacts (like inflation and higher bond yields).
• Sticky Inflation: Inflation that remains elevated due to structural factors, such as supply chain disruptions and energy costs, rather than temporary geopolitical spikes.

1. The Current Market Landscape

The S&P 500 has experienced a significant rally, characterized by a "broadening out" beyond mega-cap tech stocks. Growth is now visible in sectors like memory, robotics, and automation—all downstream components of the AI infrastructure build-out. However, this rally is occurring alongside rising bond yields, creating a tension between equity performance and fixed-income attractiveness.

2. The Fed Model and Valuation Tension

The core debate centers on the Fed Model, which posits that if the S&P 500 earnings yield is higher than the 10-year Treasury yield, stocks are the preferred investment.

• The Risk: As Treasury yields rise, they converge with the S&P 500 earnings yield. If bond yields exceed the earnings yield, the risk-to-reward ratio for equities becomes unfavorable, suggesting the market is overvalued.
• Current Status: Despite the recent rise in yields, the Fed model currently suggests the S&P 500 remains "a touch undervalued," though the margin is narrowing.

3. Lessons from 2022: The "Yields Win" Scenario

The speakers highlight 2022 as a cautionary case study. During that period, despite strong earnings growth, the rapid explosion in Treasury yields caused significant valuation compression, leading to a year-long bear market. The key takeaway is that when interest rates rise fast enough, they can overwhelm positive earnings data, causing sentiment to shift toward a "tightening cycle" that the market feels unable to withstand.

4. The Role of Inflation and Geopolitics

A central argument is whether the current rise in yields is merely a temporary geopolitical reaction to conflict or a sign of deeper, structural inflation.

• Evidence of Sticky Inflation: The speakers argue that inflation has moved beyond geopolitical shocks and is now embedded in services and supply chains.
• The Transmission Mechanism: Rising crude oil prices act as a catalyst. If oil prices remain elevated (e.g., near $100/barrel), it creates a "long tail" of higher input costs for petrochemicals, fertilizers, and agriculture. This compounds supply chain stress, which in turn keeps bond yields elevated.
• Market Sensitivity: The market is currently highly sensitive to this narrative. Intraday price action shows that optimism regarding geopolitical de-escalation is quickly erased, with liquidity returning to the market and pushing yields back up and stocks down.

5. Synthesis and Outlook

The market is currently caught in a battle between earnings growth and interest rates.

• Bullish Perspective: If oil prices remain range-bound (e.g., below $90) and supply chain pressures do not compound, interest rates may stabilize. This would keep the valuation backdrop supportive for equities.
• Bearish Perspective: If oil prices sustain levels at or above $100, the resulting supply shock will keep yields high enough to "subsume" the benefits of good earnings, potentially leading to a market correction similar to 2022.

Conclusion: The sustainability of the current equity rally depends on whether the "supply shock" remains contained. Traders are advised to monitor the relationship between energy input costs and bond yields, as these are the primary indicators of whether the current valuation of the S&P 500 can be maintained or if the market will succumb to the pressure of rising interest rates.
