Whats the correlation, if any?

I've noticed something weird chart wise whilst looking at CMY, CHP and RFN. IMO there seems to be a strong correlation in price movement between RFN and CMY only over the last 6 months since Dykes and Dunlop came to CMY. Yet there is no public evidence of a relationship between the two companies.

Sorry I'm unable to post the pic of the three companies overlayed in comparison, but check it out yourselves. Try a 6 month comparison of chart of the above companies and you'll see what I mean.

CHP and RFN SP should correlate strongly as CHP owns part of RFN by virtue of its ownership in Digital4ge. Whilst CHP owns a small percent of CMY and they share the same directors (Dykes and Dunlop) I don't expect much correlation between CMY and CHP as CMY is just a shell and a small part of CHP's interests.

It can't be mere coincidence that CMY and RFN can shadow each other so tightly.. or is it.
