# UBS Group's $617B Q4 2025 Filing Cut SPY by Half While Quietly Accumulating Its Own Stock

> UBS Group AG cut its SPY ETF position by more than half (from $27B to $12.3B) in Q4 2025 while growing its self-owned UBS stock to $6.8B — a restructuring that reshuffled the entire top-15.

UBS Group AG filed its Q4 2025 13F showing $616.7 billion across 8,980 unique holdings — a 3.4% decline from the $638.4B reported in Q3. But the headline isn't the AUM dip. It's the dramatic reshuffling inside the top 15: SPY dropped from #1 ($27.0B) to #4 ($12.3B), while UBS's own stock climbed into the top 12 at $6.8B. TL;DR AUM: $616.7B (Q4 2025), down 3.4% from $638.4B (Q3 2025) Holdings count: 8,980 unique positions (up from 8,763) SPY slashed: From $27.0B (#1, 4.22%) to $12.3B (#4, 2.00%) — a 54% reduction in value New top holding: Nvidia (NVDA) at 3.25%, worth $20.1B UBS own stock: $6.8B (1.10%), up 19.2% from $5.7B — accumulated while cutting elsewhere QQQ also cut: From $11.5B to $7.1B (down 38%) Gold (GLD): Entered top 15 at $5.1B (0.82%) Whale Score: 65.25 The SPY Halving: From #1 to #4 SPY was UBS's largest holding in Q3 at $27.0B (4.22%). In Q4 it dropped to $12.3B (2.00%). That's not price action — the S&P 500 didn't decline 54% in one quarter. UBS actively reduced its SPY allocation by selling roughly half the position (from 40.5M shares to 18.1M shares). Similarly, Invesco QQQ dropped from $11.5B to $7.1B. This looks like a systematic shift away from U.S. equity ETF wrappers toward direct stock holdings. Nvidia, Microsoft, and Apple all moved up in the rankings as SPY dropped. UBS Accumulating Its Own Stock UBS Group AG stock sits at #12 in the filing at $6.8B (146.3M shares, 1.10%). In Q3 it was $5.7B (138.6M shares, 0.89%). The firm added 7.6M shares while the position grew 19.2% in value. Self-accumulation of this magnitude in a wealth management firm's 13F is distinctive — it reflects either corporate treasury activity or client-directed holdings in UBS shares managed through the U.S. entity. Gold Enters the Picture SPDR Gold Trust (GLD) entered the top 15 at $5.1B (0.82%), up from below-threshold in Q3. Combined with the ETF reduction, this suggests UBS is rotating some allocation from equity beta into real assets. What Analysts Might Misread Misread #1: “AUM declining 3.4% means outflows” The decline is consistent with SPY/QQQ position reductions, not client departures. Direct stock holdings actually grew. This is portfolio restructuring, not shrinkage. Misread #2: “UBS buying its own stock is a conflict” Many global banks hold their own shares in 13F portfolios due to client-directed mandates, corporate treasury activity, or structured product hedging. It's structural, not necessarily a bet. Frequently Asked Questions Why did UBS cut its SPY position in half? UBS reduced SPY from $27.0B (40.5M shares) to $12.3B (18.1M shares) in Q4 2025. The shift appears to be a systematic rotation from ETF wrappers toward direct stock holdings. What is UBS Group's largest holding now? Nvidia (NVDA) at 3.25% ($20.1B), followed by Microsoft at 3.03% ($18.7B) and Apple at 2.64% ($16.3B). Does UBS hold its own stock in the 13F? Yes. UBS Group AG shares are the 12th largest position at $6.8B (1.10%), and the position grew 19.2% quarter-over-quarter.
