HSBC's shares experienced a remarkable jump of over 3% early Wednesday, as a series of updates instilled a renewed sense of optimism among investors. The lender's commitment to purchasing approximately $3 billion in shares marks a significant step in its ongoing efforts to revitalize its flagging stock price. This latest move follows a $5 billion buyback announced earlier this year, indicating that the bank has now executed $18 billion in share buybacks during N Quinn's tenure as CEO.
