Jamie dimon to wells fargo: go ahead, make my day

Jamie Dimon at the 2016 World Economic Forum in Davos, Switzerland. David A. Grogan | CNBC It sounds like Jamie Dimon has been brushing up on his Sun Tzu. The JPMorgan boss appears to be

goading one of his biggest rivals into the perilous terrain of global investment banking. He suggested in an interview with Bloomberg that, if Wells Fargo wants to compete internationally,

it'll have to buy a Wall Street franchise. That would recklessly push the otherwise boring lender led by John Stumpf deeper into businesses it doesn't know well. Three hot frontier

markets to invest in now San Francisco-based Wells Fargo's generally narrower focus on U.S. home buyers and corporate borrowers appeals to investors these days. Simplicity has trumped

cost of capital. History suggests that kind of derring-do is fraught with danger, however. It would be uncharacteristic for Wells Fargo, and undoubtedly spook its shareholders, including

Berkshire Hathaway. Stumpf will be familiar with Warren Buffett's aversion to investment banking. Such a bold move would distract Wells Fargo from the traditional lending at which it

excels and developing the technology needed to attract a new generation of customers. Surely, Dimon wouldn't want any of that to happen. Trump vs. Clinton: The election no one wants
