Conexant was the one I was thinking of. Good thing I dumped it when I did. I wish I would have sold it when it was above $100 but I still make a good profit. When it started dropping it went down like a rock over just a few months.
The best spinoff was Boeing which wasn't really a spinoff. Rockwell sold the aircraft and rocket portion of their business to Boeing and we received BA shares as a result. The Rockwell Collins was a true spinoff (or division of the company) and those shares have done pretty well and pay a dividend.
