This week is a classic year-end setup: a holiday-shortened tape, falling participation, and a market that can drift higher on seasonality — until one rates move or one headline reminds everyone that liquidity is a risk factor, not a footnote.
In late December, “what matters” shifts from fundamentals to mechanics. Depth gets thinner, spreads widen, and price impact rises. That means modest flows can create big moves, and intraday reversals can look more dramatic than they truly are.
Seasonality is supportive into late December and early January, but the trade works best when investors aren’t already heavily committed. If exposure is already elevated, you often get a grind rather than a melt-up — and any risk-off impulse tends to hit crowded leadership first.
The market remains highly sensitive to the path of inflation and the implied path of cuts. If yields stay stable or drift lower, the “duration complex” stays favored. If yields rise, the market often rotates defensively — and in thin liquidity, that rotation can look abrupt.
Think in scenarios, not predictions: (a) stable yields → slow upside drift, (b) yield pop → quick de-risking in crowded names, (c) surprise macro headline → outsized move, then mean reversion. The edge is sizing, patience, and letting the market show its hand.
