TheStreet's Jim Cramer is keeping an eye on Boeing (BA) Wednesday when the aerospace company releases its third quarter earnings results before the opening bell. Cramer says investors should wait for the conference call before jumping on Boeing. He says, 'the first trade in Boeing is often wrong...you can't read headline numbers and make any judgements, it's much too hard.' Cramer says investors will also want to pay close attention to what the company says about whether there is a wide body glut as the Delta (DAL) CEO recently indicated. Finally, Cramer says he wants to hear about defense. He says since Lockheed Martin (LMT) didn't raise for 2016, the question is, will Boeing raise for 2016? Analysts polled by Reuters are expecting Boeing to post earnings of $2.22 a share on $24.7 billion for the quarter. Shares of BA are up almost 7 percent year-to-date.
