I have no idea why Cummins Engine (CMI) is up 14% this AM to the $72s; I do see a news event involving Caterpillar (CAT), and Navistar but fail to see a direct connection - I could be missing the forest for the trees. Either way I am going to use this opportunity to cut back my position from a 1.6% stake to 0.6% (I actually bought some yesterday as it spiked downward to its 50 day moving average, but not enough of a stake to mention, so sort of lucked out on those shares)If anyone can decipher why that news is good for Cummins or if there is something else going on behind the scenes with this name, feel free to add a comment. We'll buy back on future pullbacks.[Apr 30: Cummins Engine Excellent Report on Strong International Sales]...
