The large volume and continuos down trend tells me that this stock will continue to go down. The way that it is trading, it could mean that bad news is forthcoming. From the chart, it looks like CDN could breakdown into the mid-twenties. I think it's a sell for the short-term with the idea of buying it back when the chart (with strong volume) shows a real rebound. It's always smart to go with the trend. Don't try to pick a bottom on this one. Wait until the rebound is clear. Shorts often let stocks trade up in the early morning (i.e. 9:30 to 10:15a.m.) and then hit the stock. Longs might want to get out at this time. Simply my opinions.
