NEW YORK, Dec. 28, 2025, 9:28 a.m. ET — Market closed
Zurich’s SIX Swiss Exchange is dark today — as it is every Sunday — but “closed” doesn’t mean “quiet.” With the Swiss market heading into one of its first full sessions since the Christmas shutdown, investors are using the weekend to game out a familiar year-end problem: how much of the recent rally is real conviction, and how much is thin liquidity plus seasonal optimism.
The Swiss Market Index (SMI) — the flagship blue-chip benchmark for Swiss equities — last traded on Tuesday, Dec. 23, and it did so in style, notching a fresh intraday record (13,288.66) before settling at 13,242.80, up 0.6% on the day. [1]
That matters because the SMI isn’t just “Switzerland’s Dow.” The index includes 20 of the largest and most liquid Swiss stocks and represents roughly three-quarters of Swiss equity market capitalization, making it the main global reference point for Switzerland’s biggest listed companies. [2]
Why Monday’s Swiss open could feel bigger than usual
The SIX calendar around Christmas can create a “compressed price discovery” effect: Swiss equities pause, while macro news keeps moving. SIX’s own holiday calendar for the Swiss Stock Exchange shows market holidays around Christmas (including Christmas Eve, Dec. 24, plus Dec. 25–26), leaving Swiss investors to catch up once the next regular session arrives. [3]
In other words: when Zurich reopens, it’s not reacting to one overnight headline — it’s digesting multiple days of global positioning.
The global tone: a calm U.S. tape, but still a “Santa Rally” mindset
The most recent cue from New York was subdued. U.S. equities ended Friday’s post-Christmas session (Dec. 26) marginally lower in thin trading, snapping a short winning streak but remaining close to record territory. Strategists framed the action as typical year-end profit-taking rather than a change in trend; Carson Group’s chief market strategist Ryan Detrick described it as a pause after a strong run during the seasonal “Santa Claus rally” window. [4]
For Swiss large caps — which are heavily tilted toward global defensives like healthcare and consumer staples — the significance isn’t that Wall Street slipped by a hair. It’s that global risk appetite hasn’t obviously cracked, even with liquidity thinning and year-end books being squared.
Another key cross-current: booming precious metals and the “real asset” bid
A second theme running through late-December markets is the surge in precious metals. Reuters reported gold and silver hitting fresh record levels amid holiday-thinned trading and a cocktail of macro narratives — from central-bank demand to broader concerns about currency debasement and global debt. [5]
Why should SIX investors care? Because Switzerland sits at the crossroads of global capital, commodities finance, and “safe-haven” reflexes. Big commodity and luxury flows often show up indirectly through Swiss-listed multinationals, the franc’s behavior, and portfolio rotations into perceived stability.
Switzerland-specific headline risk: defense readiness enters the conversation
One of the more striking Switzerland-related headlines over the weekend was geopolitical rather than corporate. Reuters reported that Lieutenant General Thomas Suessli, head of Switzerland’s armed forces, said Switzerland cannot defend itself against a full-scale attack and needs to boost military spending amid rising risks from Russia. He cited equipment gaps and argued that neutrality only has value if it can be defended. [6]
That isn’t a direct input into Monday’s open for Roche or Nestlé — but it can affect the market’s backdrop: sovereign risk perceptions, fiscal debates, and (in extreme cases) the premium investors attach to “stability trades,” a bucket where Swiss assets often live.
What investors should know before the next SIX session
With the exchange closed today, the edge comes from preparation — not prediction. Here are the practical things investors tend to miss when the market reopens after a holiday cluster:
1) Expect wider spreads early — and don’t confuse that with “real selling.”
After multi-day pauses, the first hour can be dominated by price discovery, rebalancing, and catching up to global moves. For less liquid Swiss names (and even some SMI constituents), spreads can widen briefly.
2) Watch the “outside market” signals that Swiss stocks tend to follow.
For Switzerland, that usually means a three-part dashboard:
- U.S. equity momentum (still constructive, but thin) [7]
- Big macro/safe-haven narratives (boosted lately by precious metals) [8]
- Switzerland/EU geopolitics (back in headlines this weekend) [9]
3) Know where liquidity will disappear next week.
The end of the year is about to deliver another round of calendar-driven market structure. U.S. traders have a full session on New Year’s Eve (Dec. 31), while U.S. markets are closed on New Year’s Day (Jan. 1, 2026); U.S. bond trading closes early at 2 p.m. ET on Dec. 31. [10]
Even if you’re focused on Zurich, these closures matter because cross-border flows, hedging, and ADR-related liquidity can get weird fast.
Outlook: the base case remains “modest gains,” but with selective risk
Swiss equities typically aren’t priced like a high-beta rollercoaster — the SMI’s sector mix tends to dampen extremes. Looking into 2026, UBS Wealth Management recently wrote that it sees potential for equity prices to rise in 2026, estimating around 5% for the Swiss Market Index (SMI) (and around 10% for a global equity benchmark). [11]
That’s a “steady grind” outlook — not a moonshot — and it fits the way many global allocators use Switzerland: as a core holding when they want quality balance sheets, dividends, and relative resilience.
For additional context on how 2025 has behaved, SIX reported in its November exchange figures that the SMI rose 4.9% in November to 12,834, contributing to a 10.6% increase across 2025 to date at that point in the year. [12]
The bottom line for Monday’s Swiss open
The Swiss market is heading into its next session with three forces in tension:
- Technically strong pricing (the SMI just printed record territory before the holiday break) [13]
- Supportive global sentiment that hasn’t rolled over, even as trading gets thin [14]
- A louder geopolitical and “real asset” backdrop, with Switzerland-related security headlines and record precious metals adding a defensive undertone [15]
That combination often produces a very Swiss outcome: not necessarily fireworks, but a market that can move sharply in the first hour — then settle into a calmer, fundamentals-driven rhythm once liquidity normalizes.
