An unidentified investor has sold its entire stake in the Zurich-listed bank.

An unnamed institutional UBS shareholder sold all its SFr503 million ($621 million) stake, exploiting recent rises in the bank’s shares, Bloomberg reported earlier this week. 

The identity of the investor wasn’t revealed. UBS declined to comment to WealthBriefing yesterday when asked about the matter. 

The newswire said the investor offered around 16 million shares through an overnight placing, which was priced at SFr31.46 per share. The report quoted terms it had seen; the price was a 1.4 per cent discount to the bank’s closing price of SFr31.91 on Monday this week. 

Since the start of January, UBS shares have risen about 12 per cent. The news report said UBS stock fell in Zurich trading on Tuesday morning, by as much as 1.4 per cent, before recovering somewhat. On Wednesday, the share price was down about 0.4 per cent from the open around late-morning, Zurich time. 

The offering was reportedly arranged by Goldman Sachs.

At the end of July, profits at Swiss private bank UBS increased by more than anticipated to $2.4 billion in the second quarter of 2025, supported by its global wealth management division and trading revenues.
