KC, please ignore him and continue sharing your articles. In fact I find your articles so informative that I attend your course. Through the exercises I understand that it takes so many work to write the articles which you share like simple essay. I respect you for this free sharing.

I think the criticism against KC is irrational. In investment we all have different methods. There is no need for angry if others put out different opinions. We should instead appreciate it as it help us to look from different angle. I don't there is a perfect method or else all of us here will be rich long time ago. Any opinions should be appreciated as it may remind us of areas that we missed out.

Interesting discussion, really appreciate you all for the sharing. It is blogs and discussion like this which attract me to here.
