I've no clue why. Guinor's candlestick price pattern has simply looked suspicious to me for many months. The daily drop with pull-up at the close, day after day forming a "horizontal line with hanging icicles" is not seen in any other gold stock. I don't know what it means -- it seems to me more that the price is being artificially held up rather than artificially held down, but what do I know? If a broker pool tries to put a "ceiling" on a stock against real buyer interest, I've read that the pool usualy fails after a while and the price breaks out upwardly. The volume in Guinor is so light that such standard maxims may not apply. A group of insiders may be orchestrating the whole thing.
I have a little Guinor (thanks to jeepdriver) and a little Cassidy and I'm not very happy about either one. My third Guinean mining investemnt, Semafo, has been a dandy -- so far.
