The amusing thing is, the performance of these companies apparently has little to do with whether or not they can get Ex-Im Bank loan guarantees. On December 4, 2015, the last time the Ex-Im Bank authorization legislation was signed into law, a share of Boeing stock sold for $148.50. But even as the Ex-Im Bank was reauthorized back in December 2015, it had a separate problem – because it didn't have enough directors on its board, it was confined to approving loan guarantees for no more than $10 million. That doesn't help a company like Boeing, which signs contracts to sell in multi-billion-dollar units. So for the last three and a half years, Boeing has looked elsewhere for financing – and, in fact, it essentially set up its own bank to help finance its deals. And the price of Boeing stock today? As of Friday, a share of Boeing stock sold for $395.86. That's a 266 percent increase in less than three and a half years. So why, exactly, does Boeing need the Ex-Im Bank?
