Ahead of the JPMorgan Chase shareholder vote Tuesday to split the chairman and CEO roles currently held by Jamie Dimon, influential banking analyst Richard Bove predicted on CNBC an outcome in favor of Dimon.
But Bove of Rafferty Capital added, "It should be 75 to 25 [percent]."
"If you look at this guy's career," he explained in a "Squawk Box" interview, "he goes into JPMorgan Chase when it's all messed up as a result of making big bets on the dot-com area and he turns it around into a company that makes more money than any other bank in the world, except for the big Chinese monoliths."
JPMorgan has outperformed other bank stocks, Bove continued, adding that Dimon doesn't lose money and "he takes care of the government ... when there's a major crisis."

Two influential shareholder advisory groups, Institutional Shareholder Services (ISS) and Glass Lewis, have recommended that JPMorgan shareholders vote to split Dimon's role as chairman and chief executive. They've cited the bank's $6.2 billion "London Whale" trading losses as a need for more oversight of company executives.
"What in heaven's name do [critics] think this company could do in assisting in terms of assisting the United States economy, giving people jobs, that it's not doing?" Bove said. "It lends $800 billion. It protects a trillion dollars in deposits. It does what we want it to do. And it makes money for its shareholders. Why are we fooling around this way?"
The AFSCME Employees Pension Plan, the Connecticut Retirement Plans & Trust Funds, Hermes Equity Ownership Services, and various New York City pension funds originally issued the non-binding proposal calling for an independent chairman.
A similar measure received 40 percent of the vote last year—right after the disclosure of the London losses.
"We're sitting around discussing some silly thing called corporate governance," Bove argued. "There's no evidence that if you have a split chairman and a CEO that your company is going to do better than if one person has both positions."
While the roles of chairman and CEO should remain with Dimon, there are going to be some dramatic changes on the board, Bove said. "[We're probably going to see a change in the structure of what the lead director does ... and on the communications between the board and the management team."
