Sustaining the S&P 500's Rally: A Delicate Dance with Risk

The S&P 500’s 24.7% surge in 2024 marked its second consecutive year of gains exceeding 20%, a rare feat in market history. Yet as traders celebrate this technical triumph, a darker question looms: Can this rally survive the storm of valuation excesses and policy uncertainty now gathering on the horizon? The answer hinges on reconciling two stark realities—the market’s short-term optimism, fueled by falling volatility and technical momentum, with the long-term risks of tariff-driven inflation, geopolitical tension, and overvalued equities. For investors, the path forward demands a blend of opportunism and caution.

The Technical Rally: A Triumph of Hope

The S&P 500’s recent gains have been bolstered by a collapse in market fear. The

highlights this complacency, with the "fear gauge" hitting levels not seen since the 2000s. Meanwhile, technical indicators such as the 50-day moving average crossing above the 200-day line—a classic "golden cross"—have fueled optimism. These signals, coupled with a 9.5% one-day surge in early 2025 after a U.S.-China trade truce, have emboldened bulls to push targets as high as 5,700 by year-end.

Yet beneath this surface lies a precarious imbalance. reveals valuations at 2.8x sales—well above the 10-year average of 2.2x. This overextension suggests that even a modest contraction in earnings or multiples could trigger a sharp correction. Indeed, Carter Worth’s analysis warns of a potential drop to 4,200—a 32% decline from February’s peak—if the P/S ratio reverts to historical norms.

Valuation Risks: The Elephant in the Room

The market’s exuberance ignores a critical truth: earnings growth has stalled. shows estimates falling for nine consecutive weeks, down to $268.49 by April—a 2.2% drop from early 2025. With price-to-earnings multiples at 19.6x (above the 10-year average of 18.3x), even a modest earnings miss could pressure valuations further.

This is not the first time markets have flirted with such extremes. The 1920s and 1930s saw similar rallies end in calamity, while the late 1990s tech boom—often cited as a parallel—benefited from falling rates and a Fed eager to support growth. Today’s environment is far less forgiving. Rising Treasury yields (now at 4.48%) and a Fed hesitant to cut rates amid tariff-driven inflation risks mean bonds, not equities, offer the safer return.

Policy Uncertainty: The Sword of Damocles

The greatest threat to this rally is not valuation but policy. President Trump’s trade agenda—coupled with China’s retaliatory measures—has introduced a new era of economic friction. While a 90-day truce in early 2025 provided a brief reprieve, the structural damage to global supply chains and inflation remains unresolved.

Consider the math: Every 1% increase in tariffs adds 0.2% to core inflation. With the Fed紧盯inflation at 2.3% in late 2024, further tariff hikes could force prolonged rate hikes, stifling the very economic growth markets are pricing in. Meanwhile, fiscal expansion—needed to offset private sector weakness—faces political gridlock. The U.S. faces a “no-win” scenario: cut rates and risk inflation, or tighten and risk recession.

Investment Strategy: Hedge While the Rally Runs

The paradox is clear: the S&P 500’s technical momentum remains intact, yet its foundations are crumbling. Investors face a binary choice—ride the rally or brace for a fall. Our advice? Hedge the exposure.

• Take Profits in Overbought Sectors: Tech stocks (e.g., NVIDIA) and AI plays have led this rally, but their valuations are now stretched. shows a divergence from broader market trends, raising the risk of a sector-specific correction.
• Use Put Options: Buying puts on the S&P 500 ETF (SPY) or sector ETFs like XLK (tech) offers downside protection without abandoning equity exposure.
• Increase Cash and Bonds: Allocate 10-15% of portfolios to U.S. Treasuries (e.g., TLT) or inverse ETFs (e.g., SH) to mitigate volatility.
• Focus on Defensive Sectors: Healthcare (XLV) and utilities (XLU) offer stability in turbulent times, though recent leadership shifts (e.g., UnitedHealth’s 17.8% plunge) demand scrutiny.

Conclusion: A Rally Built on Sand

The S&P 500’s 20% rally is a testament to the market’s “animal spirits”—but these spirits are increasingly divorced from reality. With valuations at precarious heights and policy risks mounting, this rally is less a sustainable climb and more a final rally before the music stops. Investors would be wise to dance with caution, hedging their bets while the party continues. As history shows, the road from exuberance to correction is often swift—and unkind to those who linger too long.
