The bromance between Warren Buffett and Jamie Dimon grows deeper.

Buffett’s Berkshire Hathaway snatched up 35.6 million shares of Dimon-led JPMorgan Chase in the third quarter, according to filings revealed Wednesday.

Dimon and Buffett have joined forces on issues recently. The duo penned an op-ed claiming that quarterly earnings forecasts are bad for the economy. And they are working with Amazon to create a health care company for their employees.
