What I'm looking for is for the RSI to find support in the weekly chart on the Aug/09 low. This means that there could be a little more weakness before we see the first buyers returning, if no support is found in the 35-40 zone (RSI, that is), then the longer term bullish trend is broken and that may be a good time to sell.

Needless to mention that my preferred scenario is for CMM to bottom out quite soon.
