Allianz Global Investors

Indeed, UOB is working just as hard as its peers to improve its long-term performance.

For instance, it recently said it will sell its asset management arm to Allianz Global Investors for $555 million and forge a strategic distribution partnership with Allianz.

UOB's goal is to be able to provide its customers with a broader range of investment solutions, which could support the growth of its wealth management business.

The way I see it, with high expectations across the banking sector, it may be the underdog that offers the most potential at this point.
