With a 40% rise with no news one has to wonder what is happening in VZ. This 40% rise occured with virtually no volume 3.9million shares. Which means somebody wanted in and did not care what price they were paying. Since there seems to be an urgency to the action today I would imagine sometype of news coming out soon.
Remember the reverse happened in April where someone went short by 4 million shares. We all know what happened next. Since the regulators did not clamp down on that action I think the trading houses have no fear about using insider info.
