I've tried to treat you with some respect even as you've posted misleading statements again and again. It's useless, you seem to truly think that you're fooling everyone.
Your last post is filled with so many crude attempts at (self-?)deception that I'm puzzled where to even begin.
Examples from the post I'm replying to *alone*:
* three data points can't possibly show a three-year trend (slope). this is called first differences, and you only get two of those from three points * you ignored most historical earnings data, which left us with only points that supported your point. * 18.3% is (really) not significantly different from 18.6% * 16.7% is (laughably) not significantly different from 16.8% * you stated that 16.7% is the lowest net margin ever. That is yet another glaring error. For many of us, "ever" extends back before the year 2000. The company is about 15 years old, and data back to the early '90s is very easy to get. In fact I posted plenty of pre-2000 earnings data less than a week ago.
The arguments you are trying to use are too transparent to fool anybody. Give it up.
