Well, okay. Sorry to be rude. Mawcheck's numbers are indeed what you say assuming you simply take highest point to lowest point. So, 20-40% is an okay range (although they're trending downward from the 40's to the 30's to the 20's...)
But, those peak and valley points have a lot of time and volatility between them for the most part.
If you look at rate of change, like we've seen recently, then the picture is different. Especially with the huge volume associated with it.
The rapid rise at the start of May was unusually strong to confound things. Before that, there were lots of shares traded in the 25-27 range, and I think HOTT will find lots of resistance in the 26's.
I'll be trying to find cash to buy more if HOTT hits the 25's
