RE:TimberrrrVolume has increased by about 15k per day over the last 10 days. I don't have the exact data, but it looks liike RBC might have unloaded over 100k shares, maybe as high as 150k. It amounts to a dollar volume of about $14 million to $20 million. It is not huge when considering the company's size, but in such a short period it is obviously influencing the price, negatively.
Few funds or institutions hold this much MRC. Matco Financial and DFA do. And there is a TD fund with with about 100k shares. It is likely that the selling from the RBC broker is approaching an end if these funds are liquidating part of their position. If they were to liquidate all, then the selling would only be half way done.
