Calibre (CXB on the TSX.V exchange,) trades very little as can be verified at Stockwatch, for example. *The share price has been between .06 and .08 these past six weeks on relatively low volume after coming back from its year low.
What may have caused this 100% rise in SP is a rumour that management could be more than just looking for acquisitions. Not much to go on, yet, this rise comes after filing to deregister from the SEC and announcing the closing of a private placement at .05. Mind you, two directors subscribed to this PP.
I figure Calibre is a good one to watch. I recently bought a few shares, not a major investment.
