UBS shares surged 3.8%, marking their largest increase in two months, following an upgrade from BNP Paribas analyst Jeremy Sigee, who raised the target price from 27.5 CHF to 35 CHF. Sigee anticipates increased stock buybacks and believes concerns over revised Swiss capital rules are overstated, suggesting that capital releases from overseas subsidiaries may mitigate potential impacts. While UBS may not address the new regulations in its upcoming full-year results, it could provide clarity on these capital releases, reassuring investors.
