1359 GMT - HSBC Holdings' cost guidance restricts forecast upgrades, with its wealth-management offering crucial to the market's view on the bank, UBS analysts say. The wealth segment delivered for the London-based bank in the second quarter, with wealth non-interest income up 21% and 8% annualized net new money growth, UBS writes. However, banking net interest income is the larger driver of revenue, the analysts add. The signal that HSBC might look to invest in revenue opportunities in 2027 is also key, UBS says. As a result, profit margins might be tighter than UBS expected. UBS leaves its earnings per share estimates for 2026 through 2028 largely unchanged as higher income is offset by additional costs. HSBC shares are down 4.6% in London.
