Funny you mention this stock. I bought it for my ira a few times in the 6's and 8's. I don't know anything about it, it just showed up on my screener and it filled a void.
What makes you like it? Do you think they are going to be bought?
It's a 3G provider. Why would it double in 2013? While it look cheap it has -rev growth and 3G is a dinosaur. I don't think it's a double unless it's rolling out 4G asap (doesn't look to be). The TV stuff is a bottomless pit.
I have bought CEL before so I am tell you from my experience. Many people buy it for its dividend rate but they pass all their income to the shareholders as dividend so low P/E does not mean anything. You will also need to pay foreign tax on your dividend which is about 6%. Don't expect a bounce on that.
