UOB shares jump 10% in 1 week to record highs — Is the cheapest Singapore bank finally catching up to DBS and OCBC?Okay so quite a few of you have asked me about UOB this week.And I get why.UOB’s share price jumped almost 10% in 1 week, including a 4.7% gain in a single session — without any earnings result.For a stock I bought in the low S$33s when everyone hated it, this has been a satisfying ride.But all-time highs force a decision.Is UOB — still the cheapest of the 3 Singapore banks — finally catching up to DBS and OCBC?Or is this a momentum move that changes nothing about why UOB trades at a discount in the first place?In plain English — should I buy more UOB at S$44, or stick with OCBC and DBS?I want to cover 3 things:1. Why all 3 Singapore banks rallied this week?2. Whether UOB’s valuation discount is justified?3. What I am doing with my UOB position today?https://financialhorse.com/uob-shares-jump-10-in-1-week-to-record-highs-is-the-cheapest-singapore-bank-finally-catching-up-to-dbs-and-ocbc/
