Once again this year, some enterprise IT names are falling in AH trading in response to a weak earnings report. This time, the culprit is IBM, which posted a huge revenue miss thanks in large part to a 17% Y/Y drop in hardware sales. Flat software sales didn't help either. Big Blue tried to put much of the blame on deal-closing/execution issues, but the fact U.S. federal and China were named as weak spots might have some investors an edge. EMC -1.3%. HPQ -1.1%. CSCO -0.7%. RHT -1.2%.
