I would have thought it was a double top more than head and shoulders. But in any case technical analysis is valid for AVZ because, despite the low SP, the volume of shares is fairly high and therefore statistical correlation of price movement with patterns becomes more certain.

The share is a buy now (IMHO) for anyone who hasn't already, but if it retraces back a bit more I will find some money myself and buy even more shares. On a fundamental level I think China would be nuts not to develop this mine.
