52 week highs, page-15

Fantastic run from CLH since end of Nov where SP was at 94c. Now 122c!! I took a 5-6cent profit back in October and am obviously kicking myself. The reason i exited is i now feel i have to fully understand a business before holding... and that includes being able to understand the macro surrounding the business. I know CLH has done exceptionally well but i don't understand the environment in which it works. Nevertheless, the ann confirms a brilliant interim is due next month. Congrats to holders.
I don't hold CCP for same reason.
