The Bull Market Trap
The tape does not lie. Prices are high. Yields are stubborn. Investors are trapped in a cycle of confirmation bias. After three years of relentless gains, the market is navigating a precarious peak. BlackRock’s latest internal assessment, shared via their podcast The Bid on January 16, suggests that equity momentum remains intact. Carrie King and Oscar Pulido argue that artificial intelligence investment and robust earnings growth provide a fundamental floor. However, a deeper look at the technical architecture of this rally reveals a more complex reality. The S&P 500 has defied traditional gravity since 2023. This is not merely a recovery. It is a structural shift in how capital is allocated.
The Three Year Streak
Institutional memory is short. The rally that began in late 2023 has extended through 2024 and 2025 with surgical precision. According to data compiled by Bloomberg, the index has returned over 50 percent on a cumulative basis during this period. This performance was fueled by a unique cocktail of fiscal stimulus and a technological arms race. The following table illustrates the performance metrics that have defined this era.
| Year | S&P 500 Annual Return | Primary Market Driver |
|---|---|---|
| 2023 | 24.2% | AI Speculation and Rate Peak |
| 2024 | 11.5% | Corporate Earnings Recovery |
| 2025 | 18.7% | AI Monetization and Productivity |
Risk is now concentrated. The top five companies in the index represent a disproportionate share of the total market capitalization. This concentration creates a fragile equilibrium. When BlackRock discusses momentum, they are essentially discussing the continued dominance of hyperscalers. These companies are spending billions on capital expenditures. The market is betting that this spending will translate into exponential margin expansion. If that expansion fails to materialize, the momentum will evaporate.
The AI Capex Reality Check
Capital expenditures are surging. Silicon is the new oil. Large-cap tech firms have committed hundreds of billions to data center infrastructure. This is the foundation of the BlackRock thesis. As reported by Reuters, institutional inflows into the semiconductor and cloud infrastructure sectors reached record levels in the final quarter of 2025. But there is a hidden cost to this growth. Depreciation and amortization are beginning to weigh on balance sheets. The ‘show me the money’ phase of AI has arrived. Investors are no longer satisfied with promises of future utility. They demand immediate revenue contribution from generative AI tools.
Valuations are stretched. The forward price to earnings multiple for the technology sector has decoupled from historical norms. To visualize this disparity, we examine the current valuation landscape across the broader market as of mid-January.

The Earnings Growth Mirage
Earnings are the ultimate arbiter. BlackRock points to earnings growth as a pillar of support for current prices. However, much of this growth is synthetic. Share buybacks have artificially inflated earnings per share (EPS) figures across the S&P 500. When companies use cheap debt or excess cash to reduce share count, the underlying business performance is obscured. We are seeing a divergence between top-line revenue growth and bottom-line EPS. This gap is widening. According to Yahoo Finance historical data, the quality of earnings has been declining as companies resort to aggressive accounting treatments for AI-related investments.
The Federal Reserve remains a wild card. Inflation has proved more resilient than the consensus anticipated. While the market expects a series of rate cuts, the ‘higher for longer’ reality is still exerting pressure on small-cap stocks and highly levered firms. This creates a two-tiered market. The giants thrive while the rest of the economy struggles with the cost of capital. This divergence is unsustainable in the long run. Momentum can only carry a market so far before the gravity of interest rates pulls it back to earth.
Forward Looking Milestone
The next critical data point arrives on February 12. The release of the January Consumer Price Index (CPI) report will serve as the ultimate test for the current rally. If core inflation remains sticky above 2.5 percent, the Federal Reserve will be forced to maintain its restrictive stance. This would directly challenge the valuation multiples currently enjoyed by the technology sector. Watch the 10-year Treasury yield closely as we approach this date. A move above 4.5 percent would likely trigger a significant rotation out of momentum stocks and into defensive assets.
