TheStreet's Jim Cramer asks how Boeing can be down even though the earnings were so fabulous. Cramer says that Boeing is a complicated story. Boeing is very inexpensive all of a sudden because the earnings came from taxes and margin work and not because of free cash flow, which is what investors wanted to see. Cramer says that the stock had been dogged because everyone, including Cramer, thought it was because of the Export-Import Bank reauthorization which hangs in the balance and not knowing whether the republicans would go against it. Boeing didn't have the explosive free cash flow that investors thought it did. Boeing is one of the stocks in Cramer's charitable trust portfolio. Cramer thinks it is a buy but he may be alone.
