Carrier's a blue chip that largely invented air conditioning around 1902. Originally I owned Rockwell International decades ago which, around 2001, split into Rockwell Automation and Rockwell Collins, a respected maker of aircraft electronics and radio equipment. Rockwell Collins was acquired by United Technologies for stock and cash. UTX merged with Raytheon.
In April, I received shares in Raytheon and some in Carrier and Otis, the elevator company. It's a long, complex story involving many successful spinoffs, a story that's been very, very profitable for me.
I only own blue chips and almost never sell them.
