Spikes up and downThis is a very volatile stock and is not for the faint of heart. If you use margin, at least leave enough wiggle room so you don't have to sell at the low end to meet margin. Probably today the spike down is due to the Can $ spiking up due to the Nafta deal with the US. Crooks and co, are always eager to take advantage of any possible situation to make their money from the downside. That is how they make their money by being predators in the market. And this co partly due to the stupidities of its management sometimes and partly due to outside factors, is vulnerable to short sellers and other prredators. Also take into account that money is moving from sector to sector at a moments notice due to market forces. GL.
