December’s Big Question: Santa Rally or Coal?

​November Was a Messy Hand-Off
December is here, and markets are walking in with a limp. November turned into a volatility festival: U.S. stocks stumbled hard, especially tech, with the Nasdaq taking the worst of it. Europe, strangely enough, held up better — the Stoxx 600 even eked out another monthly gain, making it five green months in a row.

So the setup for December feels split-screen: the U.S. looks bruised, Europe looks sturdy, and everyone’s staring at tech like it’s both hero and hazard.

The Case for a Santa Rally
There’s still a bullish holiday script on the table. History helps: Fidelity’s data shows the U.K.’s FTSE 100 has finished December higher in most recent years, and traders are now pricing a very strong chance that the Bank of England cuts rates this month. If that happens, it could pour fuel into risk assets just as the calendar turns festive.

In the U.S., rate-cut expectations are also drifting upward again, and each time those odds rise, global stocks tend to catch a lift. The Fed and ECB are both expected to keep rates steady at their final meetings, but “steady” can still be market-friendly if investors believe cuts are next in line.

In short: central banks might hand investors the holiday tailwind they’re hoping for.

The “Bah Humbug” Case
But December isn’t walking into a clean slate. The same issues that spooked markets in November are still hanging around like smoke in the room. AI valuations remain the big stress point. Some investors are still uneasy about how fast hyperscalers are spending — and whether that spending stays profitable once the hype cycle cools.

Europe’s central bank has already warned about frothy U.S. tech pricing and the risk of a sharp, synchronized drop if sentiment turns. That fear doesn’t go away just because it’s December.

Then there’s crypto. Bitcoin has been sliding, and analysts expect more weakness as newer investors bail out and some long-term holders sell into the post-halving phase. If crypto keeps draining confidence, it can drag broader risk appetite down with it.

The Calendar Is Loaded With Triggers
Even if you believe in Santa, December has a packed schedule that can flip the mood fast. Key central bank decisions are coming from the Fed, the Swiss National Bank, the Bank of England and the ECB. Each one is a potential spark — not necessarily because of what they do, but because of what they signal about 2026.

By the time the month ends, markets won’t just be pricing year-end performance. They’ll be pricing next year’s narrative — and right now that narrative is still fuzzy.

Bottom Line
December has two scripts fighting for control. One says seasonal strength plus rate-cut hope equals a Santa rally. The other says AI nerves, valuation risk, and crypto weakness could leave investors chewing coal instead of cookies.

​Either way, this last month won’t be boring. It’s a high-stakes finale to a year that refused to follow tradition — and it may set the tone for what kind of market 2026 becomes.
