Rare 20-Year Scenario in U.S. Stocks: Year-End Liquidity Vacuum and Market Consensus

On Monday, the “Santa Claus rally” paused. The S&P 500 fell 0.35%, Dow Jones dropped 0.51%, and Nasdaq declined 0.50%.

Year-end trading sees most institutional and quant traders on holiday, causing extremely thin market liquidity. This has two consequences:

1. Shallow market depth — even small profit-taking triggers gap-down moves;
2. Price discovery dysfunction — price swings driven by liquidity inertia rather than fundamental reassessment.

This technical sell-off mirrors last week’s gains: no sellers during the rise, no buyers during the fall. Recovery often occurs once institutions return, either via rapid technical repair or a slow upward volatility path.

Tesla Order Shock
Tesla led the tech FAANG decline, down over 3%. Supplier L&F in Korea slashed Cybertruck-related contract execution from KRW 3.83 trillion to only KRW 973 million (99% cut). Cathie Wood of ARK also sold $30 million in Tesla stock, magnifying downside pressure in thin markets.

Silver “Panic” Affects Equities
Silver fell over 8%, gold retreated to ~$4,300. The drop was liquidity-driven: profit-taking forced leveraged positions to liquidate, prompting cross-market hedge funds to sell liquid equities, further pressuring tech stocks.

Microsoft’s Custom Chip Strategy
Microsoft partners with Broadcom to develop custom AI chips, shifting some supply from Marvell. This highlights the drive for computational sovereignty and potential 2026 semiconductor profit redistribution.

Trump and Fed Independence
Trump hinted he has a candidate for the next Fed chair but may announce in January, reiterating Powell should resign and considering administrative pressure to enforce aggressive rate cuts.

Unprecedented Wall Street Optimism
S&P 500 rebounded nearly 90% from October 2022 lows. Bloomberg surveyed 21 top strategists — none forecast a 2026 decline. Average consensus: +9% S&P 500 growth. Some expect consecutive double-digit returns for four years, but zero-disagreement sentiment carries hidden risk.

Caution: Hidden Risks in Extreme Consensus
Analysts warn: prolonged Fed rates, potential U.S. tariffs on Canada/Mexico, and corporate earnings revisions. High valuations could lead to a 20% crash if a recession hits, amplified by Bitcoin and other risk asset volatility.
