Wall Street sees risk-on return despite valuation fears as markets price 87% chance of a December policy pivot.
MARKET INSIDER – Global equities staged a decisive comeback, reversing a weak start to December as the market’s highest-beta assets—Bitcoin and AI-linked technology stocks—jumped, signaling a sharp return of risk-on sentiment. With the Dow Jones, S&P 500, and Nasdaq Composite all posting gains, the rally was fundamentally driven by a 3.8% surge in Bitcoin and strong rebounds from AI bellwethers like Nvidia and Oracle. This synchronization reinforces the current market mechanism: where the two most speculative sectors dictate the direction for traditional indices. For international investors, the rally is less about fundamentals and more about the delicate balance between FOMO (Fear of Missing Out) and the high probability of a monetary policy pivot.
The immediate catalyst overriding recent pessimism is the spiking optimism regarding the U.S. Federal Reserve. Markets are now pricing in a greater than 87% chance that the Fed will announce an interest rate cut at the conclusion of its December 10th policy meeting, a dramatic increase from mid-November. This dovish expectation has effectively nullified recent “risk-off” drivers, which included persistent inflation worries, dangerously elevated valuations, and the severe crypto slump that saw Bitcoin record its worst day since March.
However, beneath the technical and seasonal tailwinds—December is historically the third-best month for the S&P 500—deep fissures remain. The market rally is narrowly concentrated, relying almost entirely on the continued, rapid expansion of the AI infrastructure buildout. As Mark Hackett, Chief Market Strategist at Nationwide, notes, while bulls enjoy strong technical and fundamental factors (such as steady fund flows and improved breadth), “The bear’s argument relies on concern over the sustainability of the AI buildout and elevated valuations.” This indicates that the market is trading not on current earnings, but on the future promise of technology that some analysts fear may be overvalued.
The current rebound is thus a highly vulnerable convergence of hope and hype. The market is betting simultaneously on sustained, exponential growth from the AI giants—which drives the stock indices—and on the Fed cutting rates, which allows liquidity to flow back into volatile assets like Bitcoin and speculative tech. If the Fed fails to deliver the dovish pivot currently priced in, or if the “sustainability” concerns surrounding the AI sector materialize, the sharp rebound will likely give way to an equally swift, and perhaps far more severe, correction.
